APPLICATIONS
Isolauryl Alcohol belongs to the family of Guerbet alcohols (high molecular weight of saturated primary alcohols with branch of the carbon chain).  As their both alkyl chains are linear, they features low viscosity, biodegradability, clarity and thermostability. They are also primary, branched, and saturated alcohols of high molecular weight and show the properties of
  • low irritation potential
  • low freezing point
  • low volatility
  • superior reactivity
  • good lubricant
  • greater oxidative and hydrolytic
  • better stability over unsaturated or linear alcohols containing the same number of carbon atoms

Guerbet alcohols with chain lengths upto C24 are clear liquids at temperatures 0 C whereas they are solids (white wax) with unique melting points from C28. They are raw materials in the industries of cosmetics, drug delivery, metal processing, fiber finish, thermostable and biodegradable lubricant and solvent as well as surfactant.

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.
