About
A hindered amine light stabilizer (HALS) derivative used in cosmetic and industrial formulations to protect products from UV-induced degradation. Functions primarily as an antioxidant and stabilizer.
Bis-(Tetramethyl Hydroxypiperidinyl) Sebacate is a bis-substituted HALS (hindered amine light stabilizer) molecule linked through a sebacic acid spacer. The tetramethyl piperidine moiety is a classic antioxidant functionality that scavenges free radicals generated by UV exposure. This compound is more commonly used in industrial polymers (plastics, coatings) than in cosmetics, but its antioxidant properties make it relevant for stabilizing sensitive cosmetic actives. The sebacate linker provides lipophilicity. It has no EU cosmetic restrictions and is considered low concern at typical usage levels.
Skin benefits
- Antioxidant — scavenges free radicals
- May help stabilize other cosmetic actives against UV degradation
Known concerns
- Primarily an industrial stabilizer, limited cosmetic-specific safety data
- Large molecular weight may limit skin penetration
