Patent ID: 8461097

Claim:
A method of making a fabric softener composition comprising 1% to 49% of the bis-(2-hydroxyethyl)-dimethylammonium chloride fatty acid ester by weight of the fabric softener composition comprising the step of mixing water with a fabric softener active composition (FSAC), wherein the FSAC comprises: (i) from 65 to 95% by weight of the FSAC of the bis-(2-hydroxyethyl)-dimethylammonium chloride fatty acid ester having a molar ratio of fatty acid moieties to amine moieties from 1.80 to 1.96, an average chain length of the fatty acid moieties from 16 to 18 carbon atoms and an iodine value, calculated for the free fatty acid, from 0 to 50, (ii) from 2 to 8% by weight of the FSAC of a fatty acid triglyceride having an average chain length of the fatty acid moieties from 10 to 14 carbon atoms and an iodine value, calculated for the free fatty acid, from 0 to 15, and (iii) from 3 to 12% by weight of the FSAC of an alcohol selected from ethanol, 1-propanol and 2-propanol; to form the fabric softener composition having from 1% to 49% of the bis-(2-hydroxyethyl)-dimethylammonium chloride fatty acid ester by weight of the fabric softener composition.
