Beschreibung
Cetostearyl alcohol (synonyms: cetearyl alcohol, cetyl stearyl alcohol; CAS No. 8005-44-5 and 67762-27-0) is a mixture of saturated fatty alcohols. It contains 65 to 80% stearyl alcohol (C18H37OH, 1-octadecanol) and 20 to 35% cetyl alcohol (C 16H33OH, 1-hexadecanol). The European Pharmacopoeia requires a content of stearylalcohol not less than 40% and that the sum of the contents of cetyl alcohol and of stearylalcohols is not less than 90%. Cetostearylalcohol is obtained by reduction of the appropriate fatty acids in coconut oil and palm kernel oil. Cetostearylalcohol is also a natural component in whale oil (spermaceti).
Chemische Eigenschaften
Cetearyl alcohol is a white or pale yellow, wax-like mass, plates, flakes or granules that is a combination of cetyl and stearyl alcohols, which occur naturally in plants and animals.
Physikalische Eigenschaften
Cetearyl alcohol has emulsifying and stabilizing properties, and is also known as cetylstearyl alcohol and Lanette O. It is essentially a mixture of two long‐chained stereoisomers, cetyl and stearyl alcohol. These alcohols are components of lanolin.
Verwenden
cetearyl alcohol (cetostearyl alcohol) is an emulsifying and stabilizing wax produced from the reduction of plant oils and natural waxes. Also used as an emollient and to give high viscosity to a finished product. Cetearyl alcohol is a mixture of fatty alcohols consisting primarily of cetyl and stearyl alcohols.
Cetearyl alcohol (cas# 67762-27-0) is a fatty alcohol which is understood to cause contact dermatitis. Ceteryl alcohol also appears in the preparation of solid lipid nanoparticles, nanostructured lipid carriers and nanoemulsion of lornoxicam for transdermal delivery.
Health Hazard
When used in skin care, cetearyl alcohol is completely safe for skin! Although some alcohol for skin can definitely be drying and irritating, fatty alcohols like cetearyl alcohol are the opposite. In fact, they help nourish and moisturize the skin and help give cosmetics their consistency (otherwise, you’d have a big, gloopy, gloppy mess in every jar!).
The Cosmetic Ingredient Review (CIR) Expert Panel concluded in 1988 that fatty alcohols, including cetearyl alcohol, are safe for use in cosmetic products. A subsequent 2005 review confirmed these results.
In clinical studies, cetearyl alcohol was found to have no significant toxicity and was non-mutagenic.
