Substance type:

Lauryl Betaine is an amphoteric surfactant derived from N-dodecyl-N,N-dialkanol amine with protein denaturing potency.

Lauryl Betaine is mainly used in shampoo, personal hygiene products and cleaning agents

Description of key information

Lauryl betaine is a clear, colourless crystalline solid, with a slight characteristic odour, usually available in liquid form as a clear or pale yellow liquid.

Alkyl betaines are zwitterionic ingredients comprised of tertiary ammonium substituted acetate.

They are mild surface-active agent (or surfactant) that is commonly used in hair and skin preparations.
