Sodium Tripolyphosphate (STPP)
General
Product Name
Sodium Tripolyphosphate
Description
The majority of STPP is consumed as a component in various types of
commercial detergents. Sodium tripolyphosphate (STPP) is a builder agent
and a provider of a wide range of benefits in detergent formulations.
Its role consists of sequestration of calcium and magnesium, provision
of alkalinity, transition metal ion complexation, metal oxide colloid
stabilization, and provision of substantial surface charge for
peptization and suspension of other soils. Modern builders are usually
less multifunctional than STPP, as their role is primarily focused on
binding and neutralizing the calcium and magnesium ions—the culprits of
hardness in water. Calcium and magnesium ions insolubilize anionic
surfactants by forming soap curd, LAS, and AS. They also bind to stains
and prevent their removal. Hardness ions can also flocculate soil
presenting in the wash solution, leading to its deposition on fabrics.
STPP is a colorless salt, found either in anhydrous form or as the
hexahydrate. As a chelating agent, both a bidentate and tridentate, STPP
binds strongly to metal cations, preventing them from interfering with
the sulfonate detergent. Builders like STPP have a substantial role in
detergents, including improving the removal of various stain classes and
levels (particulates, blood, grass, beverages), together with enhanced
whiteness maintenance. Builders can neutralize hardness via a variety of
mechanisms. Sequestering builders like STPP form soluble complexes with
the hardness ions. Precipitating builders like fatty acids are soluble
materials that form insoluble Ca/Mg salts. Finally, ion exchange
builders like zeolites are insoluble materials that can bind hardness
ions by ion exchange. STPP provides fast and effective binding of both
Ca2+ and Mg2+ ions. Additionally, it presents an excellent
dispersion/suspension agent for insoluble soils. However, its use is
banned or limited in some countries based on concerns about its role in
the eutrophication of surface water.

Linear Alkyl Benzene Sulphonic Acid
General
Product Name
Linear Alkyl Benzene Sulphonic Acid
Description
Linear alkylbenzene sulfonate (LAS) is now the world’s largest-volume
synthetic surfactant, which includes the various salts of sulfonated
alkylbenzenes. It’s widely used in household detergents as well as
numerous industrial applications. LABSA is an anionic surfactant, with
molecules belonging to a hydrophilic and a hydrophobic group. This is a
nonvolatile chemical compound, synthesized through the process of
sulfonation. The sulfonation process includes reagents like sulfuric
acid, chlorosulfonic acid, sulfamic acid, and diluted sulfur trioxide.
The starting material LAB (linear alkylbenzene) is a product of the
alkylation of benzene with n-paraffins. The catalyst is either hydrogen
fluoride (HF) or aluminum chloride (AICI3). LAS is further produced by
the sulfonation of LAB with oleum in batch reactors. As a compound of
homologs, LABSA comprises various alkyl chain lengths (C10 to C13 or
C14) together with phenyl positional isomers of 2 to 5-phenyl. The
phenyl proportions are dictated by the starting materials and reaction
conditions. Each of those contains an aromatic ring. Sulfonated at the
para position, it’s attached to a linear alkyl chain at any position,
with the exception of terminal one (1-phenyl). The chemical and physical
properties of LABSA differ based on the length of the alkyl chain. This
results in a variety of formulations, adequate for many applications.
The resulting surfactants are often used in the chemical industry to
improve contact between water and minerals. The majority of other
applications are featured in industrial, institutional, and commercial
cleaners. LABSA is also used as an emulsifier and as a wetting agent.
Linear alkylbenzene sulfonic acid is a highly usable synthetic
surfactant due to its relatively low cost and good performance.
Additional advantages are featured in the ability to be dried to a
stable powder. Its straight chemical chain makes it biodegradable,
adding to the environmental consciousness factor. Although some of the
competitive surfactants have advantages of greater hard-water tolerance
or better compatibility with enzymes, LABSA has overall more favorable
properties and is often more affordable. Commonly, the percentage range
of LABSA in detergent powder is 5%-28%. The amount of 5%-12% is usually
considered low-class quality. The range of 12%-16% is a mid-class
quality, while 16%-28% belong to the high-class grade.

Sodium sulphate anhydrous
General
Product Name
Sodium sulphate anhydrous
Description
While thenardite is the anhydrous form of Na2SO4, mirabilite is a
naturally-occurring decahydrate, Na2SO4·10H2O. The white, water-soluble,
solid hydrate is also known as the Glauber’s salt. It’s formed by
heating sodium chloride and sulfuric acid. This compound is used in
dyeing, glass production, and the preparation of sodium bisulfate.
Anhydrous sodium sulfate is found in the form of white crystalline
powder with an orthorhombic or hexagonal structure. It’s hygroscopic,
soluble in water, insoluble in ethanol. The decahydrate consists of
colorless monoclinic crystals, soluble in water, but insoluble in
ethanol. Sodium sulfate is one of the essential sodium salts. The
decahydrate was first prepared by Johann Glauber in the 17th century, in
the form of a by-product while making hydrochloric acid from sulfuric
acid and sodium chloride. SSA is mainly used as the filler of synthetic
detergent. In the paper industry, it’s an integral part of the Kraft
Process as the atmometer during sulfate pulp production. In the glass
industry, it’s a substitute for pure alkali. The chemical industry
implements it as the raw ingredient for the manufacturing of sodium
sulfide, sodium silicate, and similar chemical products. The application
in the textile industry is in the formulation of a Vinylon spinning
coagulation bath. It also has a purpose in the pharmaceutical industry,
in the form of a laxative. Other uses include ultramarine production,
printing and dyeing textiles, and standardizing dyes. A principal use of
anhydrous sodium sulfate is in the form of an agent to eliminate water
from organic solvents and their extracts for organic synthesis and
instrumental analysis. Sodium sulfate is a standard laboratory reagent
that can also be used in the preparation of other sodium salts. In the
laboratory, sodium sulfate can be synthesized from the reaction between
sodium bicarbonate and magnesium sulfate. Bulk sodium sulfate is
customarily purified via the decahydrate form. The anhydrous form tends
to attract organic compounds and iron compounds. The anhydrous form is
easily produced from the hydrated form by gentle warming.

Sodium Carbonate Anhydrous
General
Product Name
Sodium Carbonate Anhydrous
Description
Sodium carbonate naturally occurs in arid regions, especially in mineral
sediments formed when seasonal lakes evaporate. Since ancient times,
deposits of the mineral natron have been mined in Egypt, from dry lake
bottoms. Natron was utilized in the preparation of mummies but also in
the early manufacture of glass. The anhydrous form of sodium carbonate
is a rare mineral called natrite. Sodium carbonate also erupts from
Tanzania’s unique volcano, Ol Doinyo Lengai. It is considered to have
erupted from other volcanoes in the past as well, but these minerals
have likely been eroded due to their instability on Earth’s surface.
Sodium carbonate (Na2CO3) has been used for making glass, soap, and
gunpowder. Along with potassium carbonate, sodium carbonate was the
foundation of the alkali industry, one of the first major chemical
industries. Soda ash was also generated by burning wood and percolating
the ashes with water. The ashes were “lixiviated” in order to form an
alkali solution. After the water was boiled off, what remained was the
yielded soda ash. The particular name Soda Ash originates from the
Barilla plant, used to produce sodium carbonate through the
aforementioned process. Its scientific name is salsola soda; however, it
goes by the common names of Sodawort or Glasswort, the latter pointing
to the use in making glass. Soda ash is used in glassmaking, in the
production of sodium chemicals (sodium chromates, phosphates, and
silicates), in the wood pulp industry, manufacturing soaps and
detergents, in water softening and refining of oils and nonferrous
metals. Its hydrous crystallized form is known as soda crystals, sal
soda, or washing soda. Soda ash (Na2CO3) should not be confused with
baking soda (sodium hydrogen carbonate or sodium bicarbonate, NaHCO3).
The safety specifications for sodium carbonate can be considered less
demanding than those for the related bicarbonates, due to its lower
alkalinity.

Sodium Silicate
General
Product Name
Sodium Silicate
Description
The formulations of Sodium Silicate vary, depending on the amounts of
Na2O and SiO2. Also, replacing the sodium by another alkali metal, such
as potassium or lithium, results in other kinds of silicate glasses.
Some compounds are better suited than others for particular
applications, but they all share the same essential properties. Water
glass can be used to make silica gel beads or packets used to protect
clothing and electronics from moisture. It’s also effective in passive
fire protection, making of cement, stabilizing boreholes when drilling
wells, in the cardboard manufacturing, as a flocculant in wastewater
treatment. Additional applications are in food preservation, in the
processing of lumber and textiles, and for automotive repair. A water
glass solution can seal the pores of the eggs to protect them against
bacteria and gases when refrigeration isn’t an option. Fresh eggs stored
under cool conditions in a viscous silicate solution remain preserved
for months. Liquid glass can also harden the artificial stone, as it’s a
naturally occurring chemical in some mineral baths. Dissolved water
glass is moderate to highly alkaline. In detergents, this property
supports the removal of fats and oils, the neutralization of acids, as
well as the division of starches and proteins. The same property makes
the compound useful in the bleaching of paper pulp and the deinking of
waste paper. Small quantities of dissolved water glass can be useful in
the treatment of municipal water supplies as well as wastewater. It aids
in the formation of loose agglomerations of particles (flocs) through
adsorption of metallic ions. That process filters the water from
undesirable suspended materials. Under acidic conditions, liquid Sodium
Silicate reacts to form a hard, glassy gel. This property makes it
valuable as a bonding agent in cemented products such as concrete and
abrasive wheels. It is also an excellent adhesive for porcelain and
glass.

Sodium Metasilicate Pentahydrate
General
Product Name
Sodium Metasilicate Pentahydrate
Description
Sodium metasilicate is a silicic acid salt, classified as an inorganic
salt product. It is non-toxic, harmless, and odorless, with purifying,
emulsifying, moistening, dispersing, permeating, and PH buffering
abilities. As an aqueous solution, it is capable of hygroscopy and
deliquescence when in contact with air. Its forms include anhydrous,
pentahydrate, and nonahydrate compounds. It is estimated to be generally
less aggressive and safer to use than caustic soda (sodium hydroxide).
Sodium silicate reacts with metal oxides to establish a protective film
on metal surfaces, reducing the alkali’s tendency to corrode and
dissolve metals. This sort of protection is maintained as long as minute
amounts of soluble silica remain in the presence of water. In
conjunction with surfactants, sodium metasilicate aids the
neutralization of acidic soil, the deflocculation of particulate soil,
and the emulsification of oily and greasy soil. Furthermore, it enhances
the suspension of removed soil and prevents its reaccumulation. The
grease and dirt deposits get dispersed into small, suspended particles
that rinse away without redepositing on freshly washed surfaces. As a
builder, sodium metasilicate enhances/maintains the surfactant’s
cleaning efficiency by balancing water hardness. Also, it has the
highest active alkalinity and PH buffering index among inorganic
electrolytes, which enables its strong moistening, emulsifying, and
saponifying effect on fats. For this reason, it’s broadly used in
manufacturing high-efficiency in soaps, detergents, and metal cleaners.
Sodium metasilicate pentahydrate can substitute STPP in detergent
formulas to increase their cleaning efficiency while reducing
environmental pollution. Sodium metasilicate is also applicable in
fireproofing mixtures, insecticides, fungicides, and antimicrobial
compounds, as well as in dairy cleaning, paper deinking, and washing
carbonated drink bottles. It’s a chemical intermediate for silica gel
catalysts, an active ingredient in adhesives, and a bleaching aid to
stabilize hydrogen peroxide. Furthermore, it’s utilized as a clay
deflocculant in the ceramics industry and a boiler compound. In
combination with other salts such as sodium bicarbonate, it creates a
paint stripper for aluminum.

Sodium hydroxide
General
Product Name
Sodium hydroxide
Description
Around half of the sodium hydroxide production is used by manufacturers,
prevalently in the paper industry. Other applications include the
manufacturing of sodium salts and detergents, pH regulation, and organic
synthesis. In the petroleum industry, sodium hydroxide is utilized as an
additive in drilling mud. It increases the mud viscosity and alkalinity
in bentonite mud systems. Additionally, caustic soda neutralizes any
acid gas encountered in the geological formation as drilling progresses.
The process known as caustic washing utilizes caustic soda to clean and
improve low quality crude oil. Treating with sodium hydroxide eliminates
sulfurous impurities through reaction with weak acids. Sodium hydroxide
is broadly applied in the pulping of wood for creating paper or
regenerated fibers. It plays a crucial role in several later stages of
bleaching the brown pulp emerging from the pulping process. All of these
stages require a strongly alkaline environment with a pH > 10.5 at the
end of the phase. Sodium hydroxide reacts with aluminum and water to
produce hydrogen gas and sodium aluminate. This reaction converts a
polished surface to a satin-like finish. In the biodiesel industry,
anhydrous sodium hydroxide is a catalyst for the transesterification of
methanol and triglycerides. Food uses include washing or chemical
peeling of fruits and vegetables, as well as chocolate, cocoa and soft
drink processing, caramel coloring, poultry scalding, and thickening ice
cream. Olives can be soaked in sodium hydroxide for softening.
Furthermore, pretzels and German lye rolls are glazed with a sodium
hydroxide solution before baking to achieve crispiness. Another broad
usage of sodium hydroxide is in the production of parts washer
detergents. This includes defoamers, surfactants, and rust inhibitors. A
parts washer heats detergent and water in a closed cabinet, spraying
them at pressure against dirty parts for degreasing applications. While
parts washer detergents based on sodium hydroxide are among the most
aggressive parts washer cleaning chemicals, they are also considered
environmental improvements over the solvent-based cleaning methods.

Sodium percarbonate
General
Product Name
Sodium Lauryl Ether Sulfate
Description Sodium percarbonate is utilized primarily as a bleaching agent in cleaning products, eco-friendly bleaches, and as a laboratory source of anhydrous hydrogen peroxide. It is widely used as anionic surfactant in household detergents, such as washing powder, laundry detergent liquid, dishwashing liquid and other daily cleaners, pH regulators and water treatment products, water treatment chemicals, cosmetics, and personal care products, metal and non-metal surface treatment products, metalworking fluids, textile treatment products, dyes, and water softeners. Additionally, other uses include fungicides, algaecides, chemical synthesis, and environmental applications.
Sodium percarbonate is obtained through the reaction of sodium carbonate with hydrogen peroxide, which can be achieved via dry, spray, and wet processes. The dry method comprises spraying of aqueous hydrogen peroxide solution on solid sodium carbonate. A solid-liquid reaction yield sodium percarbonate. In the spray process, sodium percarbonate is created by a fluid bed process. Solutions of hydrogen peroxide and sodium carbonate are sprayed into a drying chamber to dehydrate. The wet process forms sodium percarbonate by crystallization.
The final product appears in the form of a white, powdered, or granular solid oxidizer.
Exposure of sodium percarbonate to impurities can lead to decomposition, resulting in the liberation of oxygen gas, heat, water, and possibly steam. These impurities include strong acids, bases, and transition metals such as copper, manganese, or chromium. Systems used for transport and storage of sodium percarbonate must be adequately vented with enough emergency venting capacity to allow the system’s contents to withstand a decomposition event without consequences.

Sodium sulphate (90%)
Description
A colorful speckle composition in laundry detergent powders and tablets
is diverse. The speckles feature exceptional dissolution behavior and
flow properties and should leave no residue or cause adverse effects,
such as staining, on the laundry. The overall composition usually
comprises a major proportion of white or neutral particles and a minor
proportion of colorful speckles. However, it’s not uncommon to have a
compound featuring a significant proportion of colorful particles as the
base, mixed with a small amount of a contrasting hue. Apart from purely
aesthetic purposes, colorful speckles can serve some practical
functions, too. Including visually contrasting particles can be a clue
to the consumer, indicating the presence of some specific ingredient,
such as bleach. If used solely as a visual enhancer, the colorful
speckles composition is commonly present in an amount of 1% – 3%. The
colorful speckles are especially suitable for incorporation in detergent
compounds which contain sodium chloride.

Disodium 4,4′-bis (2-sulfo styryl) biphenyl
General
Product Name
Disodium 4,4′-bis (2-sulfo styryl) biphenyl
Description
Optical brightening agents (OBAs), or fluorescent whitening agents
(FWAs), or fluorescent brightening agents (FBAs) are chemical compounds
with the ability to absorb ultraviolet light and re-emit it in the blue
region by fluorescence. This light-reflecting process provides an effect
of extraordinary whiteness/brightness. Optical brightener gets absorbed
from the formula by textile fibers, without getting removed in rinsing.
For that purpose, they are commonly utilized as additives with a role to
enhance the color appearance of fabric and paper through a “whitening”
effect. By compensating for the deficit in blue and purple light
reflected by the material, fluorescent brightening agents minimize the
visibility of yellow and orange hues. Once deposited on fabrics, optical
brighteners improve the crispiness of white or light-colored fabrics.
Even at low levels, their contribution to the overall whiteness
performance of the detergent formulas is significant. That asset made
OBAs a popular ingredient in almost all kinds of detergents. Most white
fabrics in the market have already been brightened during the
manufacturing process. This initial brightener gets progressively
removed by successive washes. The optical brightener’s function in the
solution is to take the role of that brightener and gradually replace it
while preserving the original features of the fabric. As the fluorescent
material loses energy, some slight changes in color may occur. New
optical whiteners, applied during the next laundering process, reverse
that effect. Chemically, brighteners are large organic molecules derived
from stilbenes or biphenyls. While the optical brightening agents
resemble old-style laundry bluing in several ways, there are significant
distinctions between the two methods. The first process results in blue
dye or pigment absorbing yellow light falling on the fabrics, thus
reflecting light richer in blue hues that enhance the brightening
effect. With the bluing process, however, the material absorbs a portion
of the light falling on it, reflecting less light than it receives. That
leads to a whiter, but not brighter appearance of the fabric.

Sodium Lauryl Ether Sulfate
General
Product Name
Sodium Lauryl Ether Sulfate
Description There are several good
reasons why SLES is highly sought-after by manufacturers, not the least
due to its chemical features. SLES also boasts great solvency, good
resistance against hard water, and high biodegradation levels. This
chemical ingredient is typically derived from palm kernel oil or coconut
oil. Sodium laureth sulfate has an extensive application in the cosmetic
industry, where it’s featured in a number of products to improve their
cleaning and emulsifying properties. Sodium lauryl sulfate (SLS) used to
be a good rival for SLES. However, SLS comes with a couple of
significant disadvantages: it has been proved to cause adverse effects
on skin and features relatively low aqueous solubility. Furthermore, its
ability to thicken the cosmetic formulation is low. At the same time,
SLES fulfills a plethora of demands at a friendly low cost. SLES is a
modified, improved version of SLS. It takes the high ground with a
series of benefits such as long-lasting bubbles, still commonly
perceived as a sign of high cleaning power. It has been proven to cause
minuscule levels of skin irritation, without stripping the epidermis of
excess moisture – a perk highly desirable among customers. Moreover,
SLES shows almost no sensitivity to hard water, which allows for the
formulation of products suitable for a worldwide market. On top of all,
sodium laureth sulfate’s biodegradation capacity meets the
eco-protection requirements. SLES biodegrades rapidly and in entirety.
Sodium laureth sulfate is used in a range of concentrations. In
cosmetics, it can go from as little as 0.01% up to 50% of the formula.
In cleaning products, the common range is from 1% to 30%.

Alpha Olefin Sulphonate (AOS)
General
Product Name
Alpha Olefin Sulphonate (AOS)
Description
A-olefin sulfonate is mostly derived from coconut oils. Alpha olefin
sulfonates are typically created by processes such as ethylene
oligomerization, or by the Fischer-Tropsch process of synthesis. The
sulphonation process starts inside a continuous thin film reactor.
High-temperature hydrolysis reacts with sultones to form a mixture of
cyclic sulfonate esters and alkene sulfonic acids. This is followed by
incorporating aqueous sodium hydroxide to neutralize the mix.
Neutralization and hydrolysis are carried out in isopropanol instead
of water in order to form Alpha olefin sulfonates in solid form. Alpha
olefin sulfonate features excellent cleaning and degreasing
properties, strong wetting effect, foam booster, slight viscosity
enhancer. It’s compatible with other surfactants, including amphoteric
and non-ionic co-surfactants. It’s gentle on the skin, without drying
effects, which makes it ideal for making sulfate-free cleansing
products. Those features, along with decent biodegradability, lead to
the high popularity of Alpha olefin sulfonate as a cosmetic
ingredient. In general, non-sulfate anionic surfactants are gradually
becoming the prime solution for use in personal care cleansing
products, particularly for scalp and hair care. The most common AOS
used in cosmetics is sodium C14-16 olefin sulfonate. This
multifunctional variety can act as a detergent, emulsifier, and
wetting agent. Properly formulated, it enhances viscosity, foaming
properties, and the production of a stable lather. Alpha olefin
sulfonate can be added to formulas on its own, in a range of 4-30% of
the final product. The concentration depends on desired properties,
such as foaming and cleansing effects.

Cocamidopropyl Betaine
General
Product Name
Cocamidopropyl Betaine
Description
CAB interacts with water, making the molecules slippery to prevent
them from sticking together. It’s an essential condition to make them
bond with dirt and oil in order to act as a cleanser and remove the
impurities with rinsing. Together with overall mildness compared to
anionic surfactants, that property makes Cocamidopropyl betaine a
common ingredient in various household formulas. Despite initial
beliefs that Cocamidopropyl betaine is an allergen, researchers have
debunked the claim. It has been found that two impurities that may
emerge during the manufacturing process might cause irritation;
however, when produced under proper conditions, the compound is safe.
Although the terms Cocamidopropyl betaine and Coco betaine are often
used interchangeably as synonyms, these two substances are not
identical. While both are created through a synthetic process and used
in similar applications, there are differences in their chemical
formulas. Coco betaine is a natural surfactant obtained from coconut
oil. Cocamidopropyl betaine can be derived from palm oil, also
featuring some other minor differences. On average, there are not many
alternatives to Cocamidopropyl betaine in terms of performance and
properties. In fact, there are not many amphoteric surfactants
available on the market. Although most glucosides are similar to each
other, their carbon chain length determines the differences. Depending
on the chain, each surfactant will provide slightly diverse
performance, particularly in terms of foaming and longevity. However,
they can substitute one another in simple formulas. Surfactant blends
are highly effective and balanced. Typically, they comprise one
anionic or non-ionic primary surfactant and secondary supporter, such
as amphoteric Cocamidopropyl betaine. Other non-ionic surfactants can
also be present in low percentages. Such a proportion makes the final
product milder, with good consistency and foaming abilities. For
instance, a quick-foaming, low viscosity surfactant supported with CAB
works well in a face/body wash formula. A thick, stable foaming agent
combined with a secondary surfactant and Cocamidopropyl betaine makes
a good shampoo.

General
Product Name
Coconut Diethanolamide (CDEA)
Description
Coconut diethanolamide is a mixture of amines able to neutralize acids
to form salts plus water through an exothermic reaction. Amines may be
incompatible with anhydrides, isocyanates, peroxides, halogenated
organics, epoxides, acidic phenols, and acid halides. In combination
with strong reducing agents, such as hydrides, amines can generate
flammable gaseous hydrogen. CDEA is typically used as a foaming agent
in shampoos, hand soaps, and bath products. Additionally, it has an
application in various types of cosmetics as an emulsifying agent; and
in detergents – such as dishwashing liquid – as a foaming agent.
Coconut DEA features good stabilizing properties. As an anti-corrosion
inhibitor, it’s utilized in metal-working fluids and polishing agents.
Additional advantages of Coconut DEA include excellent
decontamination, wetting, dispersion, and antistatic performances. In
washing detergent formulas, it’s a water softener, thickening,
foaming, and foam-stabilizing agent. Combined with other anionic
surfactants, such as LABSA, Coconut diethanolamide significantly
improves the foaming ability of the formula, making the final product
stable, rich, and long-lasting. CDEA can soften fiber textile, which
makes it particularly suitable for use in formulas for washing rigid
natural and animal fibers. The addition of Coconut diethanolamide to
the washing detergent notably enhances overall laundry effects.

Sodium Aluminosilicate
General
Product Name
Sodium Aluminosilicate
Description
Aluminosilicates can be obtained directly from the aluminosilicate rocks
or manufactured as synthetic materials. Natural aluminosilicate powders
used in investment casting are supplied with diverse Al2O3 content.
Malachite, for instance, ranges in 42–47% compared to 60% in Remasill or
Mulgrain 60%. The content of Al2O3 in the powder determines its
resistance to heat—the higher, the better. Typical contaminants in
aluminosilicate powder are Fe2O3, TiO2, and ZrO2, with a very small
content of CaO, MgO, K2O, P2O5, and Cr2O3. An important advantage of
aluminosilicate powders is their availability and affordability. Zeolite
is a member of a group of hydrated aluminosilicate minerals. They appear
in nature; however, they’re also manufactured for their ion-exchange and
selective-absorption properties. Due to the open crystal structure,
zeolites can be used as molecular sieves. Recently, such use of
synthetic zeolites has become significant in the separation of organic
compounds or as catalysts in petroleum refining. A natural or synthetic
zeolite features a three-dimensional crystal structure, in which water
molecules are held in cavities of the lattice. If the water content is
eliminated by heating, it makes space for zeolite to incorporate other
molecules of suitable size. Selective absorption makes zeolites valuable
agents in separating mixtures. They are also used in pumps for vacuum
systems, while certain types are useful in ion-exchange processes like
water-softening. A similar alkali aluminosilicate is prepared
artificially using sodium as the alkali metal. One process requires
adding aluminum sulfate to soluble silicate solutions. The other is
based on a combination of sodium aluminate with sodium silicate. In the
presence of calcium, iron, and other cations, the sodium ion is
substituted with a heavier metal ion. This method is successful for
removing metal ions from solutions, in processes such as softening hard
water. The permutite or artificial zeolite can be regenerated through
treatment with a strong sodium chloride solution that will lead to
replacing the calcium or iron by sodium. 4A Zeolite is a hydrated
silicate of aluminum and either sodium or calcium—or both. Zeolite in
its natural or artificial form has an extensive application in water
softening, as a detergent builder, and a cracking catalyst. The sodium
or potassium compounds are required for the former purpose since their
usefulness depends on the cationic exchange. When the zeolite has become
saturated with calcium or magnesium ion, it gets flooded with a strong
salt solution. After a reverse exchange of cations takes place, the
material is regenerated.

Tetraacetylethylenediamine
General
Product Name
Tetraacetylethylenediamine
Description
Tetraacetylethylenediamine, abbreviated as TAED, is an organic
compound widely used as a bleach activator in laundry detergents. It
has an active role in the cleaning process, enabling safe and
effective results in lower temperatures. TAED is a vital component of
laundry detergents as an alternative to “active oxygen” bleaching
agents, from sodium perborate to urea peroxide. While typical “active
oxygen” agents work by releasing hydrogen peroxide during the wash
cycle, that effect is only possible in temperatures below 60 °C (140
°F). On the other hand, TAED and its ability to form peroxyacetic acid
allow efficient cleaning and bleaching results in lower temperature
wash cycles. Powdered TAED can be easily stabilized by granulation,
with the support of the sodium salt of carboxymethylcellulose
(Na-CMC). Despite the comparably low solubility of TAED in cold water,
the granules still effectively dissolve in the washing solution within
a couple of minutes. After starting the washing process, it melts
easily and quickly in its entirety. At present, TAED is the principal
bleach activator used in European laundry detergent formulations, with
a substantial annual consumption. Typical concentrations of TAED range
from 1.4% to 13% in various products. TAED is essentially non-toxic
and easily biodegradable. Both Triacetylethylenediamine and its
by-product DAED have low aquatic ecotoxicity and very low toxicity in
all exposure routes. TAED, TriAED, and DAED are all fully
biodegradable and efficiently removed during wastewater treatment.
TAED is also not teratogenic or mutagenic. Its properties as a
detergent component help with reducing energy usage, subsequently
minimizing environmental impact in the process. TAED has no irritating
effects on skin and eyes. It also does not give any indication of skin
sensitization as a result of prolonged exposure, such as hand wash.
