Fatty alcohols are high molecular weight, long-chain primary alcohols with the number of carbon atoms varying from 4 to as many as 22-26. These are generally derived from natural fats and oils. The physical state of Fatty Alcohols is highly dependent on the chain length, unsaturation or saturation and branching. For example, stearyl alcohol is a saturated alcohol possessing 18 carbons and melting point of 58 deg. Celsius while oleyl alcohol is an unsaturated 18-carbon alcohol possessing one double bond and melting point of -7.5 deg. Celsius. Iso-stearyl alcohol is an 18-carbon alcohol with one methyl branch and melting point of less than -60 dec. Celsius. Fatty Alcohols have several commercial applications, including their use as lubricants, surfactants, solvents, emulsifiers, plasticizers, thickeners, and even fuels. They are the most common ingredients of personal care and home care products. They are used in a variety of cosmetics such as as shampoo, conditioner, shower gel, antiperspirant and lipstick. Fatty Alcohols are usually manufactured by two processes- the first is an oleochemical process, based on natural oils and fatty acids and the other is a synthetic route. Naturally, Fatty Alcohols are produced by transesterification of vegetable or animal derived triglycerides followed by hydrogenation of the thus formed esters to alcohol. The natural oils used are mainly palm oil and palm kernel oils (for C16-18 alcohols), coconut oil (for C12-14 alcohols) and other natural vegetable oils (like corn, soybean etc.) may also be used. In the synthetic route, petroleum feedstocks are made to undergo the Ziegler process in which Ethylene is further polymerized using triethylaluminium (TEA) as a catalyst, followed by air oxidation. The process produces even-numbered fatty alcohols.
