FIELD: chemistry.

SUBSTANCE: invention relates to the field of compositions of liquid laundry detergents. Liquid detergent composition according to the present invention can contain: (a) liquid phase; (b) water-soluble solid phase of 10 wt% to 50 wt% of the composition, wherein the solid phase contains a cleansing active substance of at least 30 wt% of the solid phase, wherein the cleansing active substance contains a surfactant of from 50 wt% to 90 wt% of cleaning active substance, and non-surfactant cleaning active substance, making from 10 wt% to 20 wt% of cleaning active substance; wherein the solid phase is dispersed in the liquid phase and wherein the water-soluble solid phase is defined as a solid substance obtained by centrifuging the liquid detergent composition for washing at 1,200g for 10 minutes; and wherein the liquid phase contains alcohol comprising from 5 wt % to 40 wt% of a liquid which is selected from a group comprising ethylene glycol, 1,3-propanediol, 1,2-propanediol, tetramethylene glycol, pentamethylene glycol, hexamethylene glycol, 2,3-butanediol, 1,3-butanediol, diethylene glycol, triethylene glycol, polyethylene glycol, glyceryl formaldipropylene glycol, polypropylene glycol, dipropylene glycol n-butyl ether and mixtures thereof, alcohol is preferably selected from group comprising 1,2-propanediol, dipropylene glycol, polypropylene glycol, 2,3-butanediol, dipropylene glycol n-butyl ether and mixtures thereof; and wherein the composition contains an anionic surfactant neutralized with a material different from an amine, ranging from 10 wt% to 50 wt% of the composition, and wherein the liquid laundry detergent composition contains an amine-neutralized anionic surfactant of less than 10 wt% of liquid laundry detergent composition; and wherein the composition has an equilibrium relative humidity of less than 65 % at 20 °C, which is measured using an eRH composition test described herein; and wherein the composition contains a hydroxyl-containing amino compound of less than 5 wt% of the composition.

EFFECT: creation of compositions of liquid laundry detergents with low relative humidity, containing less amount of hydroxyl-containing amino compounds, but providing acceptable viscosity values for the consumer and method implementation.
