Description:
Cysteamine hydrochloride is also used in cosmetics as an antioxidant, a hair straightening agent, and a hair waving agent. It functions as a reducing agent at concentrations between 5% and 12% in permanent-wave solutions
The functions of the cosmetic ingredient
ANTIOXIDANT : inhibiting reactions promoted by oxygen, thus avoiding oxidation and rancidity.
HAIR WAVING OR STRAIGHTENING : modifying the chemical structure of the hair, allowing it to be set in the style required (permanent waves or hair straightening).
REDUCING : changing the chemical nature of another ingredient by adding hydrogen (or removing oxygen).
