APPLICATIONS

Undecylenic Acid is an unsaturated carboxylic acid. The molecules of most natural fatty acids have an even number of carbon chains due to the linkage together by ester units. Analogous compounds of odd numbers carbon chain fatty acids are supplemented synthetically. Pelargonic acid, C-9 odd numbers carbon chain fatty acid, is relatively high cost fatty acid. Pelargonic acid can be prepared by ozonolysis which uses ozone is to cleave the alkene bonds. Eexample of ozonolysis in commerce is the production of odd carbon number carboxylic acids such as azelaic acid and pelargonic acid and simple carboxylic acids such as formic acid and oxalic acid. When ricinoleic acid, an unsaturated fatty acid containing one -OH group, derived from castor oil, is pyrolyzed by heating in the absence of air, it breaks down to give undecylenic acid and n-heptaldehyde. This product has the bifunctionality, odd carbon number and the position of its unsaturated solid bond at the end of the chain, makes it a versatile tool for chemical synthesis. It's anti-fungal properties are useful in cosmetics and pharmaceuticals. Undecylenic Acid and its aldehyde are used to formulate perfumes. Undecylenic acid and its zinc salt are used for the treatment and prevention of superficial fungus infections of the skin, primarily tinea pedis as well as relieves itching, burning and irritation.

Undecylenic Alcohol is one of common ingredient in flavor and fragrance. Odor description: floral, ozone, waxy.

GENERAL DESCRIPTION OF FATTY ALCOHOL
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.
