Patent ID: 7923189

Claim:
A process for manufacturing a hydrophobic salt of a layer-like metal hydroxide comprising the step of adding to a layer-like metal hydroxide salt containing trivalent, divalent and, optionally, monovalent metal cations, and one or more organic anions A of the formula (1) X—R—Y (1), wherein X is hydrogen, hydroxyl, carboxyl, sulfato or sulfo; Y is carboxyl, sulfato or sulfo, and R is an aliphatic, cycloaliphatic, heterocycloaliphatic, olefinic, cycloolefinic, heterocycloolefinic, aromatic, heteroaromatic, araliphatic or heteroaraliphatic radical having 2 to 50 carbon atoms, wherein one or more substituents selected from the group consisting of hydroxyl, amino, halogen, C 1 -C 22 -alkyl, C 1 -C 22 -alkoxy, C 1 -C 22 -alkylene-(CO)—O—(CH 2 CH 2 O) 0-50 -alkyl, C 1 -C 22 -alkylene-(CO)—O—(CH 2 CH 2 O) 0-50 -haloalkyl, carboxyl, sulfo, nitro and cyano is optionally present, in a dispersion, with intensive thorough mixing, one or more hydrophobic compounds selected from the group consisting of waxes metal soaps or a mixture thereof in an amount of from 0.2 to 200 wt. %, based on the metal hydroxide salt, and optionally removing the liquid medium to form a product, optionally drying the product and optionally isolating the product as a powder, wherein the metal soap is a compound selected from the group consisting of di-, tri- or tetravalent metals salts of saturated or unsaturated C 7 -C 43 -carboxylic acids, C 8 -C 44 -sulfonates, C 8 -C 44 -sulfates, C 8 -C 44 -phosphates, acid waxes, partly esterified acid waxes, partly hydrolyzed ester waxes and oxidized PE waxes, or wherein the metal soap is a compound selected from the group consisting of di-, tri- or tetravalent metals salts of C 8 -C 44 -alkyl ether-sulfates, C 8 -C 44 -alkylamido ether-sulfates, C 8 -C 44 -aralkylsulfonates, wherein aryl is C 6 -C 12 and alkyl is C 1 -C 32 , C 8 -C 44 -alkyl ether-sulfosuccinates, C 8 -C 44 -N-alkylsulfosuccinamates, C 8 -C 44 -acyl glutamates, C 8 -C 44 -fatty acid isethionates, C 8 -C 44 -fatty acid methyltaurides, and C 8 -C 44 -fatty acid sarcosides.
