  • Publication number: 20060225617
    Abstract: Pigments are used to impart color in finished products. The performances of pigments can be improved by coating with suitable materials rendering suitable properties. For cosmetic applications the pigments are usually surface treated with hydrophobizing material rendering the pigments hydrophobic. This invention relates to the use of polyhydroxy fatty acid preferably dihydroxysteadc acid (DHSA) and/or metallic salts of dihydroxystearic acid (Metallic DHSA) to coat pigments in particular pigments to be used in color cosmetic formulations. DHSA is produced either from crude or refined oleic acid or via chemical transformation or biotransformation of suitable substrates, used either in crude or refined form and the metallic salts are produced either using crude or refined DHSA. DHSA and Metallic DHSA are used to coat pigments and when these coated pigments are incorporated into finished products formulations such as cosmetic formulations, enhanced performances are observed.

  • Patent number: 7098351
    Abstract: This invention discloses a rapid method of production for fatty acid amide from fatty acid and urea. One example is the preparation of oleylamide from oleic acid and urea. The yields are high and oleylamide is selectively formed by judicious choice of catalyst. The production of fatty acid amide involves heating fatty acid and urea in a microwave oven with the use of Lewis acid catalyst. The product from the reaction is subjected to solvent extraction with chloroform and then followed by purification with n-hexane, ethanol and acetonitrile via recrystalization method. Such an oleylamide is preferred for application as a mould release agent, slip agent in plastic film production, water repellent and as a raw material for cosmetics production.

  • Publication number: 20060003903
    Abstract: The present invention relates to a process for producing oligomers and a method for improving the low temperature properties of fatty alkyl esters by using these oligomers. The oligomers according to the present invention are used as pour point depressant and cloud point reducer to improve the pour point and cloud point of fatty alkyl esters such as isopropyl, butyl, ethyl, ethylhexyl esters particularly fatty acid methyl esters at low temperature.

  • Publication number: 20050240041
    Abstract: The present invention relates to an improved process for producing hydroxy fatty acids preferably dihydroxy or polyhydroxy acids from unsaturated fatty acids derived from natural oils and fats. The unsaturated fatty acids extracted from natural vegetable oils or animal fats preferably palm-based oleic acid is hydroxylated or oxidized by peracetic acid which formed in situ from a mixture of hydrogen peroxide and formic acid. The process for producing dihydroxy or polyhydroxy fatty acids according to the present invention involve less cost, easier to perform and reduced reaction time. In addition, the dihydroxy or polyhydroxy acids produced according to the present invention is non irritant and suitable to be used in production of cosmetic products.

  • Publication number: 20050192452
    Abstract: A process for producing wax ester comprising of esterifying dihydroxy fatty acid preferably dihydroxystearic acid with at least one alcohol in the presence of lipase as a catalyst which is then remove by filtration. The filtered catalyst could be reuse and provides a number of cost advantages. In the preferred embodiment of the present invention, the dihydroxystearic acid is derived from palm based oleic acid and the alcohol contains 8 to 18 carbon atoms per molecules.

  • Publication number: 20050112267
    Abstract: The invention relates to a biodegradable functional fluid composition based on vegetable oil. This functional fluid suitable for lubricant, hydraulic and like fluid comprises palm olein and its by-product generated from fractionation of palm oil. The by-product is esterified by a hindered alcohol prior to blend together with palm olein and additive packages. The hydraulic fluid particularly suited for tropical climate with temperature ranging from 15-40° C.

  • Publication number: 20020019550
    Abstract: A process for the production of alpha-sulfonated polyhydric esters (ASPA) is disclosed using starting materials derived from palm oil or palm kernel oil. The process involves reacting saturated alkyl carboxylic acids or, alkyl esters with sulfonating agent, such as gaseous SO3 followed by reaction with stoichiometric amount of polyhydric alcohols. The resultant product may be bleached with bleaching agent, such as H2O2 and neutralised with an aqueous base to produce water soluble alpha-sulfonated polyhydric alcohol ester salt (ASPA). The product is obtained with good color and yield. This process is more efficient as it requires only stoichiometric amounts of reagents, and can reduce the formation of undesirable by-product such as sodium sulfonated soaps.
