Abstract:
1. A medium viscosity fabric softening composition, comprising (a) from about 1 to 20 wt. % of an oligomeric esteramine or oligomeric esterquat, obtainable by the reaction of an alkanol amine with a polycarboxylic acid and with a fatty alcohol and optionally a fatty acid, optionally followed by quaternization; and (b) an effective amount of a thickening agent or mixture of thickening agents, selected from the group consisting of (i) non-ionic water-soluble cellulosic polymer derived from the condensation of cellulose and ethylene oxide and/or propylene oxide; (ii) ethoxylated and/or propoxylated C 10-15 fatty alcohol; (iii) ethoxylated and/or propoxylated fatty alcohol polyurethane associative thickener; and (iv) cationic polyacrylate copolymer wherein the thickening agent is a non-ionic water-soluble cellulosic polymer derived from the condensation of cellulose and ethylene oxide.
