Patent ID: 7671008

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 is a quaternized amido-amine surfactant and preferably has a methylsulphate counter-ion; and the co-fragmenting agent is a sugar or a sugar alcohol.
