Patent number: 4765875Abstract: This invention relates to sulfonated lubricating agents for leather and furs. More specifically, this invention relates to a process for the production of sulfonated lubricating agent for leather and tanned furs consisting of the steps of:(a) sulfochlorinating higher fatty acids or esters of higher fatty acids having chain lengths of from 8 to 24 carbon atoms with chlorine and SO.sub.2 at a temperature of from about 20.degree. to 90.degree. C. under UV-radiation for a time sufficient to obtain a compound having a chlorine content of from about 5 to 30 percent by weight and a content of --SO.sub.2 Cl groups of from about 1 to 20 percent by weight, the ratio of chlorine atoms to --SO.sub.2 Cl groups being from about 0.7:1 to 70:1; and(b) forming a water-emulsifiable alkali metal, ammonium, or lower alkyl-ammonium salt of the compound produced in step (a).Type: GrantFiled: August 29, 1983Date of Patent: August 23, 1988Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Wolf-Dieter Willmund, Jurgen Plapper, Friedrich Pieper, Jochen Heidrich

Patent number: 4655960Abstract: The formation of troublesome microfoams in aqueous lacquer and synthetic resin dispersions, particularly in gloss lacquers, is prevented by the addition of from about 0.01 to about 1.5% by weight of a silicone-free foam inhibitor mixture. This mixture consists of (a) from about 70 to about 98% by weight of a mineral oil liquid at room temperature or a mixture of such mineral oil with a C.sub.16 -C.sub.30 branched alcohol of the following formulaR.sup.1 --CH.sub.2 --CH.sub.2 --CHR.sup.2 --CH.sub.2 --CH.sub.2 --CH.sub.2 OH (I)in which R.sup.1 and R.sup.2 are C.sub.4 -C.sub.16 alkyl radicals, (b) from about 0.2 to about 5% by weight of a microcrystalline wax, (c) from about 0.5 to about 20% by weight of hard paraffin, (d) from 0.05 to 5% by weight of hydrophobized finely divided silica, and (e) from 0 to about 10% by weight of a soft paraffin (M.p. 32.degree.-42.degree. C.). Component (a) preferably consists of a mixture of mineral oil and branched alcohol (I) in a ratio of from 50:1 to 1:1.Type: GrantFiled: January 2, 1985Date of Patent: April 7, 1987Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Juan C. Wuhrmann, Heinz Mueller, Karl-Dieter Brands, Adolf Asbeck, Jochen Heidrich
