Patent ID: 7625858

Claim:
A concentrated liquid fabric softening composition comprising: i) from 10% to 40%, by weight of the total composition, of an ester-linked triethanolamine (TEA) quaternary ammonium fabric softening material comprising a mixture of mono-, di- and tri-ester linked components; ii) from 0.1% to 20%, by weight of the total composition, of a single long chain cationic surfactant; and iii) from 0.1% to 20%, by weight of the total composition, of a co-fragmenting agent; wherein the TEA quaternary ammonium fabric softening material contains at least 10% mono-ester (by weight of the quaternary material) and has an Iodine Value of between 0 and 60, the single long chain cationic surfactant has one or more ethoxylate groups and preferably has a methylsulphate counter-ion, and the co-fragmenting agent is a sugar or sugar alcohol.
