Product Description
Cetyl Alcohol (CAS 112-92-5), also known as C16 Alcohol or Hexadecan-1-ol, is a long-chain saturated fatty alcohol. It exists as white waxy flakes at room temperature, with high purity (typically ≥98%) and mild properties. Its unique molecular structure gives it excellent emulsifying, thickening, and stabilizing capabilities, making it a core raw material in cosmetics, personal careand industrial fields. It is non-irritating to human skin, safe for daily use, and compatible with most organic ingredients.
