Abstract: The invention relates to a method for producing leather, said method being characterised in that tanned animal skins are treated in step (A) with an aqueous bath containing (a) at least one copolymer that can be obtained by the copolymerisation of (a1) at least one ethylenically unsaturated C4-C8 dicarboxylic acid or at least one derivative of an ethylenically unsaturated C4-C8 dicarboxylic acid and (a2) at least one C8-C100-α-olefin, and optionally by hydrolysis and/or at least partial neutralisation, (b) at least one paraffin which is liquid at room temperature, and (c) at least one synthetic non-ionic emulsifier, the aqueous solution being free of silicons. The invention also relates to silicon-free aqueous formulations and to the use thereof.

Abstract: The invention relates to agents for stuffing especially Cr-free tanned leather and skins. Said agents contain A) at least one modified native oil, in addition to B) at least one stabiliser LnR, wherein L represents formula (I) and Ra = H or methyl, Rb = methyl, ethyl or tert-butyl, Rc = methyl, tert-butyl, cyclohexyl or methylcyclohexyl, R represents an n-valent, optionally substituted and/or heteroatom- containing, C3- - C30- hydrocarbon radical, and n is a whole number from 1 10. The stabiliser LnR comprises a total of at least 20 C-atoms, especially a total of at least 28 C-atoms, and in the case where n = 2: R also represents -S-, -0-, - N(H)-, -CH2-, -(CH2)2-, -CH(CH3)-, -(CH2)3 -, -CH(C2H5)- or -C(CH3)2. The invention also relates to the use of the inventive stuffing agents in the production and/or treatment of leather and to a method for producing and/or treating leather with aqueous dispersions of said stuffing agents.
