Abstract: A cosmetic composition containing a polyether urethane thickener corresponding to formula I: wherein R1, R2 and R3, independently of one another, represent linear or branched alkyl and/or alkenyl groups containing from about 6 to 22 carbon atoms, x, y and z, independently of one another, represent a number from 1 to 10 and k, m and n, independently of one another, represent a number from about 10 to 200.

Abstract: Aqueous dispersions containing at least: a) a copolymer of compounds corresponding to formula (I): R1—O—CO—CR2?CH2??(I), ?in which R1 is a branched or unbranched alkyl group containing 8 to 22 carbon atoms and R2 is a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms, with monomers selected from compounds corresponding to formula (Ia): R3—O—CO—CR4?CH2??(Ia), ?in which R3 is a branched or unbranched alkyl group containing 1 to 6 carbon atoms and R4 is a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms, and b) a copolymer of compounds corresponding to formula (II): CnF2n—CH2—CH2—O—CO—CR5?CH2??(II), ?in which R5 is a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms and n is a number of 4 to 12, with monomers selected from compounds corresponding to formula (Ia), and c) emulsifiers, with the proviso that the ratio by weight between the copolymers a) and the copolymers b) is 10:1 to 1:10.

Abstract: The invention relates to cosmetic preparations containing polyetherurethane thickening agents according to formula (I), in which R1, R2 and R3 independently of one another represent linear or branched alkyl and/or alkenyl groups with between 6 and 22 carbon atoms, x, y, z independently of one another represent numbers from 1 to 10 and k, m and n independently of one another represent numbers between 10 and 200. The invention also relates to the use of said preparations for cleansing the skin and hair and for skin and hair care.

Abstract: Cosmetic preparations are comprised of a thickening effective amount of a polyether urethane thickener of the formula (I):

Abstract: An aqueous thickener composition containing an organic water-dispersible or water-soluble polymeric thickener and a viscosity reducer comprising a compound corresponding to formula (1):R.sup.1 --O--(R.sup.2 --O).sub.n --H (1)in whichR.sup.1 is an aliphatic hydrocarbon radical containing 8 carbon atoms,R.sup.2 represents an alkylene radical containing 2 to 4 carbon atoms, andn is an integer of 3 to 7.

Abstract: Water-in-oil emulsions of preferably polar oils are prepared by adding as emulsifiers or stabilizers 0.1 to 10% to weight, relative to the oil phase, of block polyesters of the general formula (I) R.sup.1 CO--(OR.sup.2 CO)y--(OC.sub.2 H.sub.4)--O--(COR.sup.2 O)z--COR.sup.1, in which R.sup.1 CO is an acyl group with 1-22 C-atoms or a hydroxyacyl group derived from a fatty acid with 16-22 C-atoms or a hydroxyacyl group (OR.sup.2 CO) derived from a fatty acid with 16-22 C-atoms, x is a number from 5 to 150 and y and z are numbers from 2 to 75, the group (OC.sub.2 H.sub.4) x making up 10 to 20% by weight of the total molecular weight.

Abstract: The invention is a process for oiling of leather and skins which imparts washing and dry-cleaning resistance to the treated leather and skins and a composition useful in the process. The washing and dry-cleaning resistance of leather is improved by impregnating the leather with an aqueous dispersion of a co-oligomer containing residues of a partial ester of maleic acid and acrylic acid and/or methacrylic acid and optionally up to 45% by weight of residues of ether hydmphilic and oleophilic monomers. The composition can contain semiesters of sulfosuccinic acid as additional oiling agents.
