FABRIC SOFTENER Russian patent published in 2014 - IPC C11D1/62 C11D3/00 C11D11/00 C11D3/20 

FIELD: chemistry.

SUBSTANCE: invention relates to methods of producing a fabric softener. Disclosed are methods of producing a fabric softener composition, containing 1-49% bis-(2-hydroxyethyl)-diethylammonium chloride of a fatty acid ester by weight of the composition, which include a step of mixing water with an active composition (FSAC), wherein the FSAC contains 65-95% by weight of FSAC of bis-(2-hydroxyethyl)-diethylammonium chloride of a fatty acid ester, having molar ratio of fatty acid fragments and amine fragments of 1.80-1.96, average chain length of fatty acid fragments of 16-18 carbon atoms and iodine number, calculated for a free fatty acid, of 0-50, 2-8% by weight of FSAC of a fatty acid triglyceride, having average chain length of fatty acid fragments of 10-14 carbon atoms and iodine number, calculated for a free fatty acid, of 0-15, and 3-12% by weight of FSAC of alcohol, selected from ethanol, 1-propanol and 2-propanol.

EFFECT: preparing a fabric softener composition with low content of flammable solvents, low melt viscosity and high stability in molten state.
