Disodium Tetramethylhexadecenyl Succinoyl Cysteine

What is Disodium Tetramethylhexadecenyl Succinoyl Cysteine?

Disodium Tetramethylhexadecenyl Succinoyl Cysteine is a synthetic compound derived from the amino acid cysteine, modified with a succinoyl group and a branched long-chain alkyl moiety (tetramethylhexadecenyl) to enhance lipophilicity and skin penetration. Classified as a skin conditioning agent in cosmetic formulations, it is typically used in serums, creams, and treatments targeted at facial skin. This ingredient functions by interacting with skin cells to support conditioning effects, helping maintain hydration and smoothness while contributing to a more uniform complexion through its influence on natural pigmentation processes. Its structure allows for stability in products, making it suitable for daily skincare routines without common preservatives or harsh additives.
