About

Tris-tributoxysiloxymethylsilane is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Tris-tributoxysiloxymethylsilane is an organosilane compound that functions as a conditioning agent and film-former in cosmetic preparations. No GHS hazard statements are listed in the source data, and it does not appear on EU Annex II (banned) or Annex III (restricted) lists under CosIng. The butoxy groups may release n-butanol under certain conditions, which has its own toxicity profile. Used primarily in nail and hair care formulations rather than skin care. Limited biomonitoring data available; precautionary approach recommended for leave-on formulations.
