A method to produce polyethylene glycol ester comprises the step of reacting polyethylene glycols with polyhydroxy carboxylic acids or estolides polyhydroxy fatty acids at a temperature of 120&#xb0; C. to 200&#xb0; C. in the absence of any catalysts.

Method to produce polyhydroxy carboxylic acid esters of polyethylene glycol

A fuel composition comprising a water-in-oil phase emulsion comprises bio-diesel; water; and at least one type of polymeric surfactant.

Fuel composition

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.

Palm-based hydroxy fatty acid

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.
