Shampoos often contain surfactants such as AOS, SLES, or SLS due to their capacity to remove oil and dirt from the hair and scalp and because they produce a good lather during washing.

Alpha Olefin Sulfonate (AOS) and Sodium Lauryl Ether Sulfate (SLES) are both suitable for body wash formulas and provide cleansing, wetting, and foaming properties. Other surfactants can be added to adjust the foam, viscosity, or cleaning strength of the final product.

SLES and AOS are commonly used in liquid hand washes for cleansing and foam. They can be combined with other surfactants and thickeners to adjust the consistency and foaming of the product.

AOS are generally used in facial cleansers as they feature good cleansing, wetting, and foaming properties. The amount used and the ingredient combination should be adjusted according to the final product and the grade of raw material.
