GENERAL DESCRIPTION AND APPLICATIONS

Fatty alcohols, derived from natural fats and oils, are high molecular straight chain primary alcohols. They include lauryl (C12), MyrIstyl (C14), Cetyl ( or palmityl: C16), stearyl (C18), Oleyl (C18, unsaturated), and Linoleyl (C18, polyunsaturated) alcohols. There are synthetic fatty alcohols equivalent physically and chemically to natural alcohols obtained from oleochemical sources such as coconut and palm kernel oil. Fatty alcohols are emulsifiers and emollients to make skin smoother and prevent moisture loss. Identical fatty esters are used to improve rub-out of formulas and to control viscosity and dispersion characteristics in cosmetics, personal care products and pharmaceutical ingredients. As chemical intermediates, the primary use of fatty alcohols are as raw material for the production of fatty sulfate salts and alcohol ethoxylates for foaming and cleaning purposes in the field of detergent industry. Chemical reactions of primary alcohols include esterifications, ethoxylation, sulfation, oxidation and many other reactions. Their derivatives and end use applications include;

Nonionic surfactants (Ethoxylates and propoxylates)
Anionic surfactants (Alkyl sulfates and alkyl ethoxy sulfates)
Chemical intermediates and polymerization modifiers (Alkyl halides, Alkyl mercaptans)
Quaternary ammonium compounds for detergent sanitisers, softner for textiles, phase transfer catalyst and biocides
Antioxidants for plastics (Alkyl thiopropionates and alkyl phosphites)
Lubricant additives (Metallic and thio alkylphosphates)
Flavor and Fragrance (Aldehydes and ketones)
PVC plasticizers (Dialkyl Phthalates, adipates and trimellitates)
Coatings and inks (acrylate and methacrylate esters)
Water treatment (acrylate and methacrylate esters)

Large amount of fatty alcohols are used as special solvents, fillers in plasticizer and insulating materials for the building industry. Fatty alcohols are used as ingredients in the industries of agricultural, foodstuff, metal processing, cosmetics, lube additive, pharmaceutical, rubber, textile, perfume and flavouring as well as synthetic detergent.

GENERAL DESCRIPTION OF FATTY ACID

Fatty Acids are aliphatic carboxylic acid with varying hydrocarbon lengths at one end of the chain joined to terminal carboxyl (-COOH) group at the other end. The general formula is R-(CH₂)_n-COOH. Fatty acids are predominantly unbranched and those with even numbers of carbon atoms between 12 and 22 carbons long react with glycerol to form lipids (fat-soluble components of living cells) in plants, animals, and microorganisms. Fatty acids all have common names respectively lilk lauric (C12), MyrIstic (C14), palmitic (C16), stearic (C18), oleic (C18, unsaturated), and linoleic (C18, polyunsaturated) acids. The saturated fatty acids have no solid bonds, while oleic acid is an unsaturated fatty acid has one solid bond (also described as olefinic) and polyunsaturated fatty acids like linolenic acid contain two or more solid bonds. Lauric acid (also called Dodecanoic acid) is the main acid in coconut oil (45 - 50 percent) and palm kernel oil (45 - 55 percent). Nutmeg butter is rich in myristic acid (also called Tetradecanoic acid ) which constitutes 60-75 percent of the fatty-acid content. Palmitic acid(also called Hexadecylic acid ) constitutes between 20 and 30 percent of most animal fats and is also an important constituent of most vegetable fats (35 - 45 percent of palm oil). Stearic acid ( also called Octadecanoic Acid) is nature's most common long-chain fatty acids, derived from animal and vegetable fats. It is widely used as a lubricant and as an additive in industrial preparations. It is used in the manufacture of metallic stearates, pharmaceuticals, soaps, cosmetics, and food packaging. It is also used as a softener, accelerator activator and dispersing agent in rubbers. Oleic acid (systematic chemical name is cis-octadec-9-enoic acid) is the most abundant of the unsaturated fatty acids in nature.
