1-Hexadecanol #CAS36653-82-4
Cetyl alcohol is a long-chain saturated fatty alcohol. It is insoluble in water, soluble in ethanol, ether and most organic solvents. It is chemically stable under neutral, weakly acidic and weakly alkaline conditions. It will not hydrolyze under normal conditions. When heated together with strong acid or strong base, esterification or saponification reaction can occur. It can undergo oxidation reaction under high temperature or in the presence of oxidants, generating aldehydes and carboxylic acids. It has good compatibility with surfactants, oils and other cosmetic raw materials. It has low volatility. It will not cause violent chemical reactions under conventional storage and application conditions. It can form esters with organic acids. It has emulsifying and thickening auxiliary properties.

cetyl alcohol is a versatile ingredient that can serve as an emollient, emulsifier, thickener, binder, foam booster, or emulsion stabilizer, depending on the formulation and need. It is derived from coconut or palm oil as well as being synthetically manufactured. It is considered by some sources to be a non-comedogenic material.
Cetyl alcohol, also known as hexadecanol, is a widely used fatty alcohol in cosmetic, personal care, pharmaceutical and chemical industries. It functions as an opacifier, thickener, emulsifying auxiliary and stabilizer in creams, lotions, ointments, hair conditioners and hair masks. It can increase the viscosity of oil-water systems, improve the stability of emulsions, prevent the separation of oil and water phases, and bring soft, non-greasy skin feel. It also acts as a consistency regulator to adjust the hardness and spreadability of paste products. In the pharmaceutical industry, it is used as an ointment base, lubricant and carrier for topical preparations, helping active ingredients spread evenly on the skin surface. In the chemical industry, it is an important raw material for manufacturing cetyl alcohol ethoxylates, cetyl sulfates and other surfactants. It can also be used to produce lubricants, plasticizers, defoamers and perfume fixatives. In textile industry, it serves as fiber softener and finishing agent to improve the smoothness and hand feel of fabrics.
