Sodium Carboxymethyl Tallow Polypropylamine is a substance used in cosmetic preparations where it acts as a surfactant (washing-active substance), hair conditioner (makes the hair easy to comb, smooth, soft and shiny and gives it volume) and antistatic agent (reduces static charges by neutralizing the electrical charge on the surface of e.g. hair). "Sodium" here refers to a sodium salt, "carboxymethyl" means that individual hydroxy groups (mostly of sugar molecules) are linked to a carboxymethyl group (-CH2-COOH) as ether.
