Cysteamine HCL
Product name: Cysteamine HCl Synonyms: cysteamine hydrochloride, cysteamine, cysteamin INCI name: Cysteamine CAS No.: 156-57-0 EINECS: 205-858-1 Quality: assay 99% up by HPLC Molecular formula: C2H8ClNS Molecular weight: 113.61 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).
