Abstract (en)

[origin: WO2004056741A1] The invention relates to a method for producing monoalky hydroxycarboxylic acid esters. The inventive method consists in reacting hydroxycarboxylic acids of the salts thereof with a mixture consisting of alcohols of a general formula (i) R<1>-OH and (II) (C2H4 )n-OH, wherein R<1> and R<2> independently represent an alkyl saturated or non-saturated, branched or non-branched group which comprises from 6 to 22 carbon atoms, and n ranges from 1 to 20 at a temperature ranging from 120 to 180 DEG C, the compounds of the formulas (I) and (II) being used at mass ratios ranging from 10:1 and 1:10.
