STABLE AQUEOUS DISPERSIONS OF QUATERNARY AMMONIUM COMPOUNDS AND IMIDAZOLINE DERIVATES

摘要

Aqueous dispersions of barely water-soluble quaternary ammonium compounds and/or imidazoline derivates are stabilized by adding water-in-oil dispersions of water-swelling cationic cross-linked polymers. The stabilizing water-in-oil dispersions consist of 30 to 70 % by weight of a cationic homo- or copolymer, 20 to 50 % by weight of a hydrophobic organic liquid, 0.5 to 10 % by weight of a water-in-oil emulsifyer and 0 to 10 % by weight of a cross-linking agent, the remaining percentage being constituted by water. These stabilizing cationic cross-linked polymers are preferably prepared by inverse emulsion polymerisation. Also disclosed is the use of such stabilizing aqueous dispersions as textile and laundry softeners.
