Uses
Used in Cosmetics and Personal Care Industry:
Cetearyl Alcohol is used as an emulsifying and stabilizing wax to help mix oil and water-based ingredients in cosmetic and personal care products. It also acts as an emollient, providing a smooth and soft texture to the skin, and is used to give high viscosity to finished products.
Used in Pharmaceutical Industry:
Cetearyl Alcohol is used in the preparation of solid lipid nanoparticles, nanostructured lipid carriers, and nanoemulsions for transdermal drug delivery. It helps improve the solubility, stability, and bioavailability of drugs, making them more effective for targeted delivery to the skin or other body tissues.
Used in Industrial Applications:
Cetearyl Alcohol is also used in various industrial applications, such as in the production of waxes, polishes, and coatings, due to its emulsifying, stabilizing, and viscosity-increasing properties.
Production Methods
Cetearyl alcohol is a combination of cetyl and stearyl alcohols. Stearyl alcohol is manufactured by transesterification and distillation of coconut or palm kernel oil using a methanol and a zinc catalyst, followed by hydrogenating the resulting methyl esters using a copper catalyst. The catalysts are removed during the fractional distillation phases, so there are little or no metals in the final product.Cetyl alcohol is manufactured by reducing ethyl palmitate (the waxy ester of palmitic acid) with metallic sodium and alcohol or under acidic conditions with lithium aluminum hydride as a catalyst.The final product melts at a temperature higher than that of the human body, which makes it useful for makeup and other things that are warmed by the skin.
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.
Flammability and Explosibility
Nonflammable
Check Digit Verification of cas no
The CAS Registry Mumber 67762-27-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,6 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67762-27:
(7*6)+(6*7)+(5*7)+(4*6)+(3*2)+(2*2)+(1*7)=160
160 % 10 = 0
So 67762-27-0 is a valid CAS Registry Number.
