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.

Abstract: Emulsifier composition containing elthoxylated alkanols. An emulsifier composition consisting of three components A, B, and C, where component A comprises a 6-14C alkoxylated alkanol with 4-12 AO units, component B 12-14C alkoxylated fat- alcohol mixture with 5-30 AO units, and component C 12-24C alkoxylated fat-alcohol mixture with 40-100 AO units, where AO = alkylene oxide. Independent claims are included for: (1) a stuffing agent for stuffing leather including one or more modified, native fatty substances and optionally synthetic stuffing agent, emulsifiers, and optionally dilution agents, especially water, and the above emulsifier composition; and (2) a method for stuffing leather and hides by treatment with aqueous liquors containing a stuffing agent and emulsifiers, where 10-90, preferably 25-75 wt.% of the stuffing agent is a relatively highly oxidized, relatively poorly sulfited neutral oil and the liquor contains 1-10, preferably 2.5-7.5 wt.% of the above emulsifier composition.
