Surfactants ammonium lauryl ether sulfate

When ammonium lauryl sulfate is reacted with ethylene oxide, the result is the larger molecule ammonium laureth sulfate. This molecule has the same detergent and surfactant qualities, but it is larger consequently it does not penetrate the skin and hair as easily. The term laureth is actually a contraction of lauryl ether. The full name is ammonium lauryl ether sulfate. 

The most common ingredient in shampoos is also the most common detergent in use in other products a class of surfactants known as straight-chain alkyl benzene sulfonates. Examples are ammonium lauryl sulfate, its sodium relative, and the slightly larger but related molecule ammonium lauryl ether sulfate (sometimes abbreviated as ammonium laureth sulfate).

Shampoo compositions generally comprise one or more anionic cleansing surfactants, which are cosmetically acceptable and suitable for topical application to hair. Anionic surfactants (negatively charged molecules) provide a lot of lather and detergency in the shampoo. The most commonly used anionic surfactants are sodium lauryl ether sulfate (SLES), ammonium lauryl sulfate (ALS), and ammonium lauryl ether sulfate (ALES), and sodium lauryl sulfate is also occasionally used. 

Sodium lauryl ether sulfate and ammonium lauryl ether sulfate are common analogues that are also used regularly as an alternative, the former having less health consequences. These compounds are prepared by the addition of ethylene oxide and are also structurally related compounds found in many beauty products of a lower pH and have a higher compatibility with other surfactants. 

DLSS, DPMS, DSIS, and a blend containing SLAS and DCAD are the components to improve the formulations skin mildness, i.e., the skin compatibility of the other surfactants present. SLES/ALAS/SLAS, i.e., sodium lauryl ether sulfate, ammonium lauryl sulfate, sodium lauryl sulfate, are examples of high-foaming basic surfactants. 

MACKAMIDE MC being a "superamide" is not soluble in water by itself below 10%. However, the addition of small amounts of anionic surfactants such as lauryl sulfate, lauryl ether sulfate, linear alkane sulfonate and even soap will clarify it. MACKAMIDE MC will respond to viscosity control with the addition of sodium or ammonium chloride.

Asgher et al. (2011b) have also reported another FI-CL method to determine retinol and a-tocopherol in pharmaceuticals and human blood serum based on the enhancement effect of the lucigenin CL reaction in alkaline medium. Surfactants including polyoxyethylene lauryl ether (Brij-35), Triton X-100, cetyltrimethyl ammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) enhance lucigenin CL intensity. With Brij-35, the enhancement was 67% for retinol and 58% for a-tocopherol. With CTAB, the enhancement was 16% for retinol whereas for a-tocopherol, the CL intensity was quenched by up to 95%. Retinol could be determined specifically in the presence of a-tocopherol using CTAB.
