ABSTRACT:
The application relates to 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 (i) a polycarboxylic acid; and (ii) a fatty alcohol or a fatty acid; or (iii) a mixture of a fatty alcohol and 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, said fabric softening composition being free of isopropanol, ethylene glycol, propylene glycol and polyglycols;(c) from about 0.2 to 2.5 wt. % of a water insoluble perfume; and(d) an effective amount of a thickening agent to provide a viscosity of from 80 to 700 mPa·s in the softening composition, said thickening agent being 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.
