Noms anglais : (C16-C18) ALKYL ALCOHOL; (C16-C18)-ALKYL ALCOHOL; ALCOHOLS, C16-18 cas no : 67762-27-0; Cetearyl alcohol; Cetylstearyl alcohol; Cetyl/stearyl alcohol; Cetearyl alcohol is a chemical found in cosmetic products. It’s a white, waxy substance made from cetyl alcohol and stearyl alcohol, both fatty alcohols. They’re found in animals and plants, like coconut and palm oil. They can also be made in a laboratory. They are used in personal care products, mainly skin lotions, hair products, and creams. They help create smoother creams, thicker lotions, and more stable foam products. Fatty alcohols are sometimes called long-chain alcohols because of their chemical formula. They usually have an even number of carbon atoms, with a single alcohol group (–OH) attached to the last carbon.Cetostearyl alcohol, cetearyl alcohol or cetylstearyl alcohol is a mixture of fatty alcohols, consisting predominantly of cetyl (16 C) and stearyl alcohols (18 C) and is classified as a fatty alcohol. It is used as an emulsion stabilizer, opacifying agent, and foam boosting surfactant, as well as an aqueous and nonaqueous viscosity-increasing agent. It imparts an emollient feel to the skin and can be used in water-in-oil emulsions, oil-in-water emulsions, and anhydrous formulations. It is commonly used in hair conditioners and other hair products
