Abstract:
1. A medium viscosity clear fabric softening composition, comprising (a) from about 1 to 20 wt. % of an oligomeric esterquat, derived from the reaction of an alkanol amine with a polycarboxylic acid and with a fatty alcohol and optionally a fatty acid, followed by partial quaternization (leading to a mixture of oligomeric esteramine and of esterquat); (b) at least about 0.2 wt. % dipropylene glycol (c) from about 0.2 to 2.5 wt. % of a water insoluble perfume; and (d) to provide a viscosity of 80 to 700 to the composition, wherein the thickening agent is 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 fatty alcohol polyurethane associative thickener; and (iii) cationic polyacrylate copolymer; said composition being clear.
