Ammonium dodecyl sulphate is the INCI name and common name for Ammonium lauryl sulfate (CH3(CH2)10CH2OSO3NH4).
The anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group.
The combination of nonpolar and polar groups confers surfactant properties to the anion: Ammonium dodecyl sulphate facilitates dissolution of both polar and non-polar materials.
This salt is classified as a sulfate ester.
Ammonium dodecyl sulphate is made from coconut or palm kernel oil for use primarily in shampoos and body-wash as a foaming agent.
Lauryl sulfates are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles at the surface-air interface.
Ammonium dodecyl sulphate is an anionic surfactant consisting of a nonpolar hydrocarbon chain and a polar sulfate end group.
Ammonium dodecyl sulphate is used as a foaming agent, and as a detergent in many industrial applications.
Ammonium dodecyl sulphate is a common surfactant found in many cosmetics and personal care products.
Ammonium dodecyl sulphate plays a crucial role in these formulations by reducing the surface tension between different substances, allowing them to mix effectively.
The chemical formula of Ammonium dodecyl sulphate is C12H29NO4S.
Ammonium dodecyl sulphate is an anionic surfactant widely used in personal care, cleaning, and detergent formulations.
Ammonium dodecyl sulphate provides effective cleansing, foaming, wetting, and emulsifying performance and is commonly found in shampoos, body washes, liquid soaps, facial cleansers, and household cleaning products.
Ammonium dodecyl sulphate's good compatibility with aqueous surfactant systems makes it a versatile ingredient for formulations requiring strong foam generation and efficient soil removal.
Ammonium dodecyl sulphate is classified as an alkyl sulfate and is an anionic surfactant.
Lauryl sulfates disrupt the surface tension of water by forming micelles around the polar water molecules.
Sulfates have been the focus of critical parties, even though they are an incredibly efficient fat remover and create a ton of foam.
Ammonium dodecyl sulphate is usually made from coconut or palm kernel oil.
Ammonium dodecyl sulphate is often used in detergents, emulsifiers (stabilizers), foaming agents, and dispersants.
Ammonium dodecyl sulphate can also be used in many detergent applications.
Ammonium dodecyl sulphate has an excellent viscosity response when formulated correctly with alkanol amides and amphoteric, and it generates large quantities of foam.
Since it is a high-foaming product, Ammonium dodecyl sulphate can be used in rug and upholstery shampoos.
Ammonium dodecyl sulphate will give off an ammonia odor when the pH is alkaline.
Ammonium dodecyl sulphate can be derived from coconut and is used primarily as a detergent cleansing agent.
Ammonium dodecyl sulphate is considered to be gentle and effective.
Ammonium dodecyl sulphate is an anionic surfactant.
This means Ammonium dodecyl sulphate lowers the surface tension of water, making the water spread more easily.
Ammonium dodecyl sulphate is added to products as a foaming agent and as a detergent.
Ammonium dodecyl sulphate must be used in a low-pH shampoo or shower gel since high-pH systems smell of ammonia.
Ammonium dodecyl sulphate is typically used at 20-35%.
Ammonium dodecyl sulphate is designed for low-pH shampoos, bath products, and cleansers requiring dense, rich foam, low color, and low odor.
Action in Solution:
Above the critical micelle concentration, the anions organize into a micelle, in which they form a sphere with the polar, hydrophilic heads of the sulfate portion on the outside (surface) of the sphere and the nonpolar, hydrophobic tails pointing inwards towards the center.
The water molecules around the micelle in turn arrange themselves around the polar heads, which disrupts their ability to hydrogen bond with other nearby water molecules.
Up to the critical micelle concentration, increasing amount of dissolved surfactant reduces the surface tension of the solution, which affords a greater ability to penetrate or "wet out" various surfaces, including porous structures like cloth, fibers, and hair.
Accordingly, this structured solution allows the solution to more readily dissolve soils, greases, etc. in and on such substrates.
Lauryl sulfates however exhibit poor soil suspending capacity.
Applications of Ammonium Dodecyl Sulphate:
Ammonium dodecyl sulphate is widely used in shampoos, body washes, shower gels, liquid soaps, facial cleansers, and other personal care formulations.
Ammonium dodecyl sulphate is incorporated into household and institutional cleaning products where effective detergency, wetting, and foam generation are required.
Ammonium dodecyl sulphate is also used in emulsifying and dispersing systems to improve the distribution of oils, soils, and other formulation components.
Ammonium dodecyl sulphate's strong surface-active properties make it suitable for a broad range of aqueous cleansing, detergent, and specialty formulation applications.
Ammonium dodecyl sulphate can be used as:
A catalyst in the synthesis of 1H-benzo[d]imidazole, quinoxaline, and 2,3-dihydro-1H-benzo[b][1,4]diazepine derivatives by reacting with benzene-1,2 diamine and aromatic aldehydes/1,2-diketones/ketones respectively.
A corrosion inhibitor for carbon steel and copper in acidic solution.
A surfactant in the fabrication of porous ceramics by gel casting.
Uses of Ammonium Dodecyl Sulphate:
Ammonium dodecyl sulphate is an anionic surfactant.
This means Ammonium dodecyl sulphate lowers the surface tension of water, making the water spread more easily.
Surfactants are also called wetting agents, and are said (somewhat paradoxically) to make water "wetter".
Ammonium dodecyl sulphate is added to products as a foaming agent, and as a detergent.
Notice in the structural formula that one end of the molecule is a long chain of carbon and hydrogen, while the other end is a salt of sulfuric acid and ammonia.
The long chain is hydrophobic, and the salt is hydrophilic, making this a good detergent and surfactant.
Ammonium dodecyl sulphate is used in many shampoos, toothpastes, and skin cleansers.
Ammonium dodecyl sulphate can be used in hard water.
When Ammonium dodecyl sulphate is reacted with ethylene oxide, the result is the larger molecule ammonium laureth sulfate.
This larger molecule has the same detergent and surfactant qualities, but is larger, so Ammonium dodecyl sulphate does not penetrate the skin and hair as easily.
The term "laureth" is actually a contraction.
The full name is "ammonium lauryl ether sulfate".
Sodium Lauryl Sulfate is the same compound and has the same uses, but the ammonium group has been replaced with a sodium atom.
Ammonium dodecyl sulphate is used as an anionic detergent or surface-active agent in hair and rug shampoos, bath products, detergents, skin cleansing preparations, hand soaps, hair dyes, conditioners, and shaving products.
Ammonium dodecyl sulphate finds extensive use in various cosmetic products, particularly in shampoos and hair care items.
Ammonium dodecyl sulphate's exceptional surfactant properties allow it to effectively remove dirt, excess oil, and impurities from the hair and scalp, leaving a clean and refreshed feeling.
Moreover, Ammonium dodecyl sulphate creates a rich lather, enhancing the overall shampooing experience.
Ammonium dodecyl sulphate's versatility extends beyond hair care, as it can also be found in certain skin care products, where it aids in creating cleansing and foaming properties.

Origin of Ammonium Dodecyl Sulphate:
Ammonium dodecyl sulphate is typically produced by reacting lauryl alcohol with sulfur trioxide gas to form lauryl sulfate, which is then neutralized with ammonium hydroxide to create Ammonium dodecyl sulphate.
This process results in a versatile surfactant widely used in cosmetics for Ammonium dodecyl sulphate's excellent cleansing and foaming properties.
