Behenyl alcohol also referred to as 1-docosanol, is a 22-carbon aliphatic alcohol, that works as a thickening, opacifying, emollient, and emulsifying agent that can be made synthetically or from plants. It functions as a hydrating component as well. It also works as a stabilizer and is used in personal care products like scrubs and body butters. It is a fatty alcohol that is unlike the drying alcohols. It is a waxy, white solid in its unprocessed state.

What is BEHENYL ALCOHOL used for?

Behenyl alcohol works as a texture enhancer to improve the appearance and feel of the product. It is also an opacifier and a thickener-cum-stabilizer which helps to regulate the viscosity of the product. It is also an emollient and an emulsifier for cosmetics and personal care products.
  • Skin care: It works as an emollient to soften and soothe the skin. After topical application, it forms a protective layer on the skin’s surface that prevents moisture loss and keeps the skin hydrated
  • Hair care: It works as an emollient in hair products to increase the hair’s moisture content and makes it more manageable


Behenyl alcohol is produced via a high-temperature, high-pressure, catalytic hydrogenation of fatty acids, and can also be produced via the Ziegler process. Alternatively, it can also be obtained from vegetable sources.
