Abstract: The invention relates to a degreasing agent for treating skins, fur, limed skins and other intermediate products in leather and fur production, and for treating wool or related protein substances, based on non-ionic surfactants of the alcohol alcoxylate type. Alcohol alcoxylates are used which are obtained by reaction with at least one alcohol ROH with n mols of at least one alkylene oxide per mol of alcohol ROH, wherein R represents an alkyl radical containing between 5 and 30 carbon atoms, and having a main chain which contains between 4 and 29 carbon atoms and is branched in the centre thereof with at least one C1 - C10 alkyl radical; the alkylene oxide comprises between 2 and 6 carbon atoms; and n represents a whole number between 1 and 100. The invention also relates to a method for degreasing skins, fur, limed skins and other intermediate products in leather and fur production, and for treating wool or related protein substances, a degreasing agent according to the present invention being used. The invention further relates to the use of said degreasing agent.

Abstract: New block copolymers (I) comprise a polyisobutenyl-succinic acid mono-esterified with a (co)polyalkylene oxide monoalkyl or monoaryl ether (i.e. a lipophilic polyisobutene block bonded to a hydrophilic polyoxyalkylene block via a succinic acid linker). Polyisobutenyl-succinic acid derivatives of formula (I) are new. [Image] L : polyisobutenyl group of number average molecular weight (Mn) 200-20000; M+>H+> or an equivalent of alkali(ne earth) metal, ammonium or mono- or polyalkylammonium ion; R : group formed from oxyethylene, oxypropylene and/or oxybutylene units; A : methyl, ethyl, propyl, butyl or aryl (optionally substituted). An independent claim is included for the preparation of the above copolymers.

Abstract: A mixture comprises: (A) mono- or polyfunctional 2-24C alcohol, thiol or amine, alkoxylated with 1-30 ethylene oxide units and 0-3 3-10C alkylene oxide units; (B) water; and (C) water-soluble polymers having repeating units containing, optionally in salt form, hydroxy, carboxy, amine, amide, nitrogen-containing heterocyclyl, thiol, sulfonate, sulfinate, sulfate, phosphonate, phosphinate and/or phosphate groups. An independent claim is included for the preparation of (I) by mixing (A) - (C), where (C) is added before, during or after the alkoxylation reaction for the preparation of (A).

Abstract: Evaluation of emulsifiers comprises preparing at least two crude emulsions in which the dispersed phase contains different tracers, mixing together equal parts of the emulsions, finely emulsifying the mixture, and determining to proportion of coalesced dispersed-phase droplets by measuring the area occupied by droplets containing at least two tracers as a percentage of the total area occupied by the sample. Independent claims are also included for: (1) use of a continuous high-pressure homogenizer in which the whole emulsion is forced through a perforated diaphragm under constant pressure to perform the emulsification in the above method; (2) use of reactive dyes, direct dyes, vat dyes, sulfur dyes, naphthols, developer dyes, disperse dyes, metal complex dyes, acid dyes, chrome dyes, cationic dyes or pigments, fluorescent dyes or fluorescence-generating donor-acceptor pairs as tracers in the above method; (3) use of emulsifiers selected from oleic acid ethoxylates, fatty alcohol ethoxylates, castor oil ethyoxylates, alkylphenol ethoxylates, C13 Oxo alcohol ethoxylates and sodium fatty alcohol polyglycol ether sulfates in the above method; (4) use of emulsifiers together with coemulsifiers in the above method; (5) use of active ingredients and/or additives in the aqueous phase and/or oil phase of the emulsion in the above method; (6) use of a microscope slide allowing preparation of emulsion films with a defined thickness of 10-50 mum for microscopic determination of the area percent of tracer-containing droplets in the above method.
