LIQUID DETERGENT COMPOSITION Russian patent published in 2014 - IPC C11D1/722 C11D1/02 C11D3/43 C11D17/08 

FIELD: chemistry.

SUBSTANCE: invention relates to a liquid detergent composition for use in textile articles, comprising component (a), component (b), component (c) and component (f), where the total content of component (a) and component (b), expressed by the formula [(a)+(b)], ranges from 50 wt % to 90 wt %, and the ratio of the mass of component (a) to the mass of component (b), expressed by the formula (a)/(b), ranges from 25/75 to 90/10; and component (a): 15 to 75 wt % non-ionic surfactant obtained by adding p1 mole of ethylene oxide to a compound of formula R-OH (where R denotes an alkyl group or an alkenyl group having 8 to 18 carbon atoms), then adding q1 moles of propylene oxide and then adding p2 moles of ethylene oxide, where p1 is a number from 3 to 30, q1 is a number from 1 go 5, the sum (p1+p2) is equal to a number from 16 to 50; and the value p1/(p1+p2) ranges from 0.2 to 0.8; component (b): anionic surfactant, and component (c): 5 to 25 wt % water-miscible organic solvent, where the water-miscible organic solvent is at least one solvent selected from a group consisting of (c1), (c2), (c4) and (c6): (c1) is ethanol, (c2) is ethylene glycol having 2 to 6 carbon atoms and glycerol, (c4) is a mono- or dialkyl ether of (poly)alkylene glycol obtained from (poly)alkylene glycol consisting of alkylene glycol links having 2 to 4 carbon atoms, and alkanol having 1 to 5 carbon atoms, and (c6) is an aromatic ether of (poly)alkylene glycol cotaining an alkylene glycol fragment with 2 to 3 carbon atoms; component (f): 0.5 to 8 wt % alkaline agent. The present invention also relates to a washing method (versions) and to use of the liquid composition.

EFFECT: obtaining a liquid detergent composition with excellent solubility in water and gold stability.
