Cetyl alchol on the surface water information
Answers
Cetyl Alcohol also known as hexadecan-1-ol and palmityl alcohol, is a fatty alcohol with the formula CH3(CH2)15OH. At room temperature, cetyl alcohol takes the form of a waxy white solid or flakes. The name cetyl derives from the whale oil (Latin: cetus) from which it was first isolated.
Other names:
Cetanol, Cetyl alcohol, Ethal, Ethol, Hexadecanol, Hexadecyl alcohol, Palmityl alcohol
Preparation:
Cetyl alcohol was discovered in 1817 by the French chemist Michel Chevreul when he heated spermaceti, a waxy substance obtained from sperm whale oil, with caustic potash (potassium hydroxide). Flakes of cetyl alcohol were left behind on cooling. Modern production is based around the reduction of palmitic acid, which is obtained from palm oil.
Uses:
Cetyl alcohol is used in the cosmetic industry as an opacifier in shampoos, or as an emollient, emulsifier or thickening agent in the manufacture of skin creams and lotions.It is also employed as a lubricant for nuts and bolts, and is the active ingredient in some "liquid pool covers" (forming a surface layer to reduce evaporation and retain heat).
Side effects:
People who suffer from eczema can be sensitive to cetyl alcohol,though this may be due to impurities rather than cetyl alcohol itself.However, cetyl alcohol is sometimes included in medications used for the treatment of eczema.
