    Abstract: Agents for the fatliquoring of, in particular, leathers and hides tanned in the absence of chromium comprise A) at least one modified natural oil and B) at least one stabilizer L n R where R a is H or methyl, R b is methyl, ethyl or tert-butyl, R c is methyl, tert-butyl, cyclohexyl or methylcyclohexyl, R is an n-valent C 3 - to C 30 -hydrocarbon radical which is unsubstituted or substituted and/or contains hetero atoms and n is an integer from 1 to 10, the stabilizer L n R having altogether at least 20, in particular altogether at least 28, carbon atoms, and, where n is 2, -R- also being -S-, -O-, -N(H)-, -CH 2 -, -(CH 2 ) 2 -, -CH(CH 3 )-, -CH 2 ) 3 -, -CH(C 2 H 5 )- or -C(CH 3 ) 2 -. The novel fatliquoring agents are used in leather production and/or leather treatment, and leather is produced and/or treated using aqueous dispersions of these fatliquoring agents.

    Abstract: Mixture comprising sulfo-functional di- or tribasic carboxylic acid esters and nonhydroxylic ethers and esters with 18-45C atoms, is new. Composition (I) comprises: (a) di- or tribasic carboxylic acid esters of formula (I); (b) nonhydroxylic ethers and esters with 18-45C; and (c) optionally alkanols of formula (II) and alkanediols of formula (III) Provided that, based on the sum of the weights of nonhydroxylic ethers, nonhydroxylic esters, alkanols, alkanediols and OR and (O)2R groups, the mixture comprises up to 85% OR groups, up to 16% (O)2R groups and up to 45% nonhydroxylic ethers and esters. ((MOOC)a-bR (COO)b)m(R )n(R )p(OH)q (I) R OH (II) R (OH)2 (III) a, b = 2 or 3, provided that b = (a) a 2-6C di- or trivalent, saturated or mono- or diunsaturated, aliphatic or alicyclic hydrocarbon group, at least 50 mole% of R being saturated or monounsaturated and having a sulfonic acid group or (b) a 6C di- or trivalent aromatic hydrocarbon group bearing a sulfonic acid group; R = branched 9-51C alkyl optionally substituted by alkoxy, alkylcarbonyloxy or alkoxycarbonyl; and R = 10-30C alkanediyl. Independent claims are included for: (1) a process for preparing (I); (2) aqueous and nonaqueous compositions comprising: (i) an ester mixture comprising (I) and optionally monoesters of formula (IV) and (V); and (ii) dubbing and/or hydrophobizing substances. (MOOC)dR COOR (IV) ((MOOC)dR COO)2R (V) d = 1 or 2.

    Abstract: Polysiloxane-containing compositions are prepared using carboxyl-containing polysiloxane(s), aprotic substance(s) which is liquid at room temperature, organic solvent(s), and up to 2 wt.% water. Preparation of polysiloxane-containing compositions comprises using: (A) carboxyl-containing polysiloxane(s) which has structural element(s) of formula (Ia), (Ib), or (Ic) per molecule; (B) aprotic substance(s) which is liquid at room temperature; (C) organic solvent(s); and (D) up to 2 wt.% water. At least one amino-containing polysiloxane which has structural element(s) of the formula (IIa), (IIb), or (IIc) per molecule is reacted, in the presence or absence of component (B). At least one dicarboxylic anhydride of the formula (IIIa) or at least one dicarboxylic acid derivative of the formula (IIIb) and then, if required, component (B) or (C) is added. R1>H, OH, 1-6C alkyl, 6-14C aryl or 1-4C alkoxy; R2>H or 1-6C alkyl; Z1>2-25C alkylene, 3-10C cycloalkylene, 6-14C arylene, -[(CH2)n-NR2>-(CH2)m]p, or structure of formula (1); n, m : 1-10; p : 1-5; A1>2-20C alkylene, optionally substituted by R3> and/or R4>, -CH=CR3>, -CR4>=CR3>-, or structure of formula (2); R3>, R4>H, 1-20C alkyl, 2-20C alkenyl, 6-14C aryl, or 1-4C alkoxy; M : H, alkali metal or ammonium, which may be substituted or cyclic; X : leaving group; Z2>2-25C alkylene, 3-10C cycloalkylene, 6-14C arylene or -[(CH2)n-NR2>-(CH2)m]p. R3> and R4> can be linked to one another with formation of a mono- or bicyclic system. An independent claim is also included for a process for imparting water repellency to or refating materials having a fibrous structure, comprising applying the inventive composition to material having a fibrous structure, allowing to act with or without simultaneously carrying out mechanical treatment steps, and optionally washing and drying.
