ARACHIDYL ALCOHOL

Arachidyl alcohol is a long-chain fatty alcohol, also called 1-eicosanol. Although its name includes "alcohol," it behaves as a waxy material and is unlike the volatile alcohols that can give some cosmetics an immediately dry feel.

ARACHIDYL ALCOHOL: what it is

Arachidyl alcohol is a long-chain fatty alcohol, also called 1-eicosanol. Although its name includes "alcohol," it behaves as a waxy material and is unlike the volatile alcohols that can give some cosmetics an immediately dry feel.

Its long chain helps explain its more structured consistency and its affinity for the oily phase of creams and lotions. The compound can also be made through biotechnology: a study of modified Crambe abyssinica roots detected arachidyl alcohol among the fatty alcohols produced.

ARACHIDYL ALCOHOL: what it does in cosmetics

In creams, lotions, and richer-textured products, arachidyl alcohol works as an emollient, helping the product leave a less rough, softer feel. It also supports the structure of an emulsion, helping water and oily components remain more evenly dispersed over the product's shelf life.

Viscosity control means a formula can be less runny and have a more substantial body, which may make the cosmetic easier to spread or dispense. This is a texture and formulation-stability role, not a treatment for acne, wrinkles, dark spots, or other skin conditions.
