What is SODIUM COCOAMPHOACETATE used for?

Sodium cocoamphoacetate is a surfactant, a compound with a hydrophobic tail and a hydrophilic head. This means it attracts oil and water, helping the different ingredients of a formula to blend, and sebum and impurities to be lifted from the skin and washed off with water. As a foam stabilizer, it increases the surface tension of the liquid that surrounds individual bubbles, resulting in a rich foam that doesn't just disappear. It is also conditioning the hair and helps creams and shower gels to glide smoothly on the skin.

Skin care: It is used as a surfactant, foam booster and conditioning agent, foam stabilizer in shaving cream, soap, makeup, cleaners. It is often used in makeup removers and products designed for use on people with sensitive skin, children and babies because of its mild and non-irritating properties
Hair care: In hair care preparations such as shampoo, conditioners, it cleanses, enhances the appearance of hair by increasing hair body, suppleness, or sheen of hair that has been damaged physically or by chemical treatment

Origin

Sodium cocoamphoacetate is made by reacting coconut acid with aminoethylethanolamine to produce an imidazoline. It is then reacted with monochloracetic acid or monochloropropionic acid in the presence of sodium hydroxide. This forms mono- or dicarboxylated products, which are supplied as amber liquids containing 40% to 50% solids. Adding sodium chloride makes the mixture more viscous.
