Patent ID: 7015187

Claim:
A method of forming a liquid fabric softener composition for later use in the rinse of a laundry process comprising the step of adding sufficient water to a solid particulate composition comprising: (A) from 50% to 95% by weight of the composition of a biodegradable fabric softening active, wherein the fabric softening active comprises a quaternary ammonium salt, the quaternised ammonium salt being a quaternised product of condensation between: a)—a fraction of saturated or unsaturated, linear or branched fatty acids, or of derivatives of said acids, said fatty acids or derivatives each possessing a hydrocarbon chain in which the number of atoms is between 5 and 21, and b)—triethanolamine; (B) from 5% to 20% by weight of the composition, of a dispersibility modifier; and (D) from 0.1% to 5% by weight of the composition a pH modifier; wherein the dispersibility modifier is a non-ionic surfactant or a fatty acid; wherein the pH modifier is a solid, water soluble Bronsted acid; and wherein the composition has 85% to 95% of the particulates having a diameter between 50 and 400 microns; wherein sufficient water is added to provide the composition of from about 0.5% to about 8% by weight of liquid composition of the fabric softening active.
