Ammonium dodecyl sulphate is an ideal surfactant for use in acidic shampoos and other personal care formulations such as hand soaps and bath products.
Ammonium dodecyl sulphate can also be used in many detergent applications.
Ammonium dodecyl sulphate has an excellent viscosity response when formulated correctly with alkanolamides and amphoterics, and it generates large quantities of foam.
Since Ammonium dodecyl sulphate is a high foaming product, Ammonium dodecyl sulphate can be used in rug and upholstery shampoos.
Ammonium Lauryl Sulfate will give off an ammonia odor when the pH is alkaline.

CAS Number: 7783-20-2 is the common name for ammonium dodecyl 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: it facilitates dissolution of both polar and non-polar materials.
CAS Number: 7783-20-2 is classified as a sulfate ester.
CAS Number: 7783-20-2 is found primarily in shampoos and body-wash as a foaming agent.
CAS Number: 7783-20-2 are very high-foam surfactants that disrupt the surface tension of water in part by forming micelles at the surface-air interface.

Identification of Ammonium dodecyl sulphate
Name: Ammonium lauryl sulfate
Synonyms: Ammonium dodecyl sulphate; Dodecyl sulfate ammonium salt
Molecular Formula: C12H25O4S.NH4
Molecular Weight: 283.42
CAS Registry Number: 2235-54-3
EINECS: 218-793-9
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.
The overall effect of these micelles is a reduction in 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.
Ammonium dodecyl sulphate however exhibit poor soil suspending capacity.
Safety of Ammonium dodecyl sulphate:
Ammonium dodecyl sulphate is an innocuous detergent.
Shampoos containing up to 31% ALS registered 6 health complaints out of 6.8 million units sold.
These complaints included two of scalp itch, two allergic reactions, one hair damage and one complaint of eye irritation.
The CIR report concluded that both sodium and ammonium dodecyl sulphate “appear to be safe in formulations designed for discontinuous, brief use followed by thorough rinsing from the surface of the skin.
In products intended for prolonged use, concentrations should not exceed 1%.
The Human and Environmental Risk Assessment (HERA) project performed a thorough investigation of all alkyl sulfates, as such the results they found apply directly to Ammonium dodecyl sulphate.
Most alkyl sulfates exhibit low acute oral toxicity, no toxicity through exposure to the skin, concentration dependent skin irritation, and concentration dependent eye-irritation.
Ammonium dodecyl sulphate do not sensitize the skin and did not appear to be carcinogenic in a two-year study on rats.
The report found that longer carbon chains (16–18) were less irritating to the skin than chains of 12–15 carbons in length.
In addition, concentrations below 1% were essentially non-irritating while concentrations greater than 10% produced moderate to strong irritation of the skin.
Occupational exposure of Ammonium dodecyl sulphate:
The CDC has reported on occupations which were routinely exposed to Ammonium dodecyl sulphate between 1981 and 1983.
During this time, the occupation with the highest number of workers exposed was registered nurses, followed closely by funeral directors.
Environment:
The HERA project also conducted an environmental review of alkyl sulfates that found all alkyl sulfates are readily biodegradable and standard wastewater treatment operations removed 96–99.96% of short-chain (12–14 carbons) alkyl sulfates.
Even in anaerobic conditions at least 80% of the original volume is biodegraded after 15 days with 90% degradation after 4 weeks.
Product advantages of Ammonium dodecyl sulphate:
excellent alternative for SLS and SLES,
concentrated form,
milder effect towards the skin than typical anionic surfactants,
capability to produce a thick and stable foam,
resistance to hard water,
high washing efficiency, even with an excessive sebum content,
ensures excellent stabilisation of polymer dispersions in lower pH ranges,
very good dispersant properties,
high biodegradability,
products manufactured using production systems covered by the GMP EFfCI system (for cosmetic raw materials).
Applications of Ammonium dodecyl sulphate:
personal hygiene cosmetics: shampoos, body wash liquids, shower gels,
agents reducing plasterboard weight,
aeration and plasticizing admixtures,
plastics, emulsion polymerisation,
additives to food packaging.
