Cetyl alcohol is a white unctuous mixture of solid alcohols consisting chiefly of n-hexadecanol. It is soluble in ethanol, ether, chloroform and toluene and insoluble in water. It conforms to the formula: CHs ( CH2 ) lKH,OH Cetyl alcohol is an important ingredient in cosmetic products like creams, lotions, etc. either as such or after ethoxylation. It is obtained by high pressure hydrogenation of palmitic acid. In certain cosmetic products, a mixture of cetyl alcohol and stearyl alcohol gives better properties than pure cetyl alcohol. Cetearyl alcohol, a mixture of cetyl and stearyl alcohols. is an odourless, white, waxy solid which is soluble in diethyl ether, benzene and chloroform. It is slightly soluble in petroleum ether, ethanol and acetone and is insoluble in water. This standard provides specifications for pure cetyl alcohol, whereas requirement for cetearyl alcohol ( mixture of cetyl and stearyl alcohols ) are given for information only. This standard is essentially based on Cosmetic, Toiletries Fragrance Association ( CTFA ) Specification For Cetyl alcohol and Cetearyl alcohol. For the purpose of deciding whether a particular requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test, shall be rounded off in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values (.revised )‘. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard. - . _- “. _ _.. ,_“._. .‘_‘~II IS 14137: 1994 Indian Standard CETYLALCOHOL FOR COSMETIC INDUSTRY- SPECIFICATION 3.2 The material shall comply with the requirements 1 SCOPE . given in Table 1.
