Abstract: An agent for conditioning and imparting water repellency to leather comprises a homogeneous mixture of(a) 10 to 35% by weight of a compound of the formula ##STR1## wherein R is linear or branched alkyl or alkenyl each having 14 to 22 carbon atoms, m is a number average from 1.0 to 1.5 and n is 2 minus m;(b) 0 to 10% by weight of non-ionic emulsifiers;(c) 0 to 3% by weight of anionic emulsifiers with the proviso that the sum of (b) and (c) is 0.5 to 10%;(d) 0 to 5% by weight of an epoxide of the formula ##STR2## wherein R' is alkyl or alkenyl having 15 to 40 carbon atoms; (e) 0 to 25% by weight of fat liquors; and(f) 25 to 89.5% by weight of water or a water-miscible organic solvent.

Abstract: Phospholipids which are obtained within the framework of protein synthesis from fermentatively produced constituents of micro-organisms may be used, following a conversion into a water-dilutable form, for example by emulsification or by a chemical modification, such as saponification or sulfonation, as greasing agents for the greasing of leather and fur skins. In this capacity they are superior to vegetable and animal phospholipids.

Abstract: Conditioning and water-repellent compositions containing agents for cellulose-containing textiles or leather comprising sulphonylureas of the formula ##STR1## wherein R is alkyl or alkenyl having 10-30 carbon atoms; B is a member selected from the group comprising ##STR2## wherein R.sup.1 is alkyl having 1-4 carbon atoms, R.sup.2 is hydrogen or alkyl having 1-4 carbon atoms and n is 2, 3 or 4;And X is .beta.-halogenoalkyl or alkenyl with 2 to 4 carbon atoms each. Also disclosed are novel sulphonylureas per se and a method of use for sulphonylureas as conditioning and water repellent compositions.
