Question

Formulation and preparation of shampoo

Answer 1

Explanation:

shampoo is a preparation of a surfactant (i.e. surface active material) in a suitable form – liquid, solid or powder – which when used under the specified conditions will remove surface grease, dirt, and skin debris from the hair shaft and scalp without adversely affecting the user.Shampoo is generally made by combining a surfactant, most often sodium lauryl sulfate or sodium laureth sulfate, with a co-surfactant, most often cocamidopropyl betaine in water.The primary surfactant is the key foaming/cleansing agent in the shampoo. When we first got started formulating shampoos the most popular primary surfactant was SLS (sodium lauryl sulfate). In more recent years it has been replaced by ALS (ammonium lauryl sulfate).
