Surfactant - Ammonium Lauryl Sulfate

INCI: Ammonium Lauryl Sulfate (ALS)



Ammonium lauryl sulfate is the generic name for ammonium dodecyl sulfate

(CH 3 (CH 2) 10 CH 2 OSO 3 NH 4).

Origin: synthetic

Appearance: Colorless or yellowish liquid


Solubility: in water

Class: Anionic surfactant

Toxicity: mild irritant to skin, eyes


Country: India



Anion Ammonium Lauryl Sulfate consists of a non - polar hydrocarbon chain and a polar sulfate end group. The combination of non - polar and polar groups gives the anion the properties of a surfactant: it facilitates the dissolution of both polar and non - polar materials. ALS is classified as a sulfate ester. It is found primarily in shampoos and body washes as a foaming agent. Lauryl sulfates are very high foaming surfactants that reduce the surface tension of water by forming micelles at the surface - air interface.

Above the critical micelle concentration, anions are organized into a micelle, in which they form a sphere with polar hydrophilic heads of the sulfate part outside the sphere and non - polar hydrophobic tails directed inward towards the center. The water molecules around the micelle, in turn, are located around the polar heads, which violates their ability to hydrogen bond with other neighboring water molecules. The overall effect of these micelles is to reduce the surface tension of the solution, which gives a greater ability to penetrate or "wet" a variety of surfaces, including porous structures such as tissue, fibers and hair. Accordingly, this structured solution allows the product to more easily dissolve dirt, grease, etc.

  • shower gels.


ALS is a harmless detergent. Shampoos containing up to 31% ALS received 6 health complaints out of 6.8 million units sold, according to the Cosmetic Ingredient Review. These complaints included two cases of itchy scalp, two allergic reactions, one hair damage and one eye irritation.

The Cosmetic Ingredient Review concluded that ammonium lauryl sulfate “appears to be safe in formulations intended for short - term use followed by thorough rinsing from the skin surface. In products intended for long - term use, not rinsed off, the concentration should not exceed 1% . "

The Human and Environmental Risk Assessment (HERA) has undertaken a rigorous study of all alkyl sulfates and applies the results directly to ALS. Most alkyl sulfates exhibit low acute oral toxicity, no skin toxicity, concentration - dependent skin irritation and concentration - dependent eye irritation. They do not sensitize the skin and have not been shown to be carcinogenic in a two - year study in rats.

Usage: Due to the rather high melting point (15 ° C), it is recommended to introduce into the recipe with heating (30 ° C)

Input: The normal percentage of input in shampoos as the main blowing agent is 10 to 25% . In indelible skin cleansers - up to 1% Storage: Store at a temperature of 25 - 30 ° C. If the storage temperature is less than or equal to 15 ° C, the product will be frozen, but after thawing at room temperature (25 - 28 ° C) and stirring until smooth, it can be used. Store in tightly closed containers.
