Abstract (en)
[origin: EP0564980A1] The present invention relates to fatliquoring compositions based on oxysulphitised oils of animal and/or vegetable origin, wherein the fatty substances used are a) 70 - 99 % by weight fatty substances of animal and/or vegetable origin and b) 30 - 1 % by weight compounds of the formula I <IMAGE> which differ from the compounds of component a) and in which R<1>, R<2> and R<3> are independently of each other branched or straight-chain, optionally substituted C1-C24-alkyl radicals, R<4> is hydrogen or a straight-chain or branched, optionally substituted C1-C6-alkyl radical, m is an integer greater than zero, and n is an integer greater than zero. The invention also provides a process for preparing fatliquoring compositions, comprising the measures of - oxidising compositions based on fatty substances containing the components a) and b) at a temperature above 40 DEG C, and - subsequently sulphitising by adding a 5 to 50 % strength by weight solution of a sulphitising agent with simultaneous or subsequent heating.
