Patent attributes
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 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) from 0% to 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.
