FIELD: chemistry.
SUBSTANCE: invention relates to the field of compositions of liquid laundry detergents. Liquid laundry detergent composition of the present invention may comprise: (a) liquid phase; (b) phase in the form of a lamellar liquid crystal; (c) phase in the form of particles; phase in the form of a lamellar liquid crystal and the phase in the form of particles dispersed in the liquid phase, and phase in the form of particles is defined as a solid, obtained by centrifuging the composition of liquid detergent for washing at a speed of 12 n (1,200 g) for 10 min, and the term "lamellar liquid crystal" in this document means a system status, in which the molecules of the surfactant are organized in stacks with a two-layer structure of the surfactant in the molten state, separated by thin layers of solvent; and while the liquid phase contains alcohol, comprising from 5 to 40 mass. % liquid, which is selected from the group consisting of ethylene glycol, 1,3-propanediol, 1,2-propanediol, tetramethylene glycol, pentamethylene glycol, hexamethylene glycol, 2,3-butanediol, 1,3-butanediol, diethylene glycol, triethyleneglycol glycol, polyethylene glycol, formaldehyde propylene glycol glycerin, polypropylene glycol, n-butyl dipropylene glycol ether and mixtures thereof, preferably the alcohol is selected from the group containing 1,2-propandiol, dipropylene glycol, polypropylene glycol, 2,3-butanediol, dipropylene glycol n-butyl ether and mixtures thereof; and while the composition has an equilibrium relative humidity of less than 65 % at 20 °C, which is measured using the eRH test described herein; and while the composition contains a hydroxyl-containing amine compound, amounting to less than 5 mass. % composition; the composition contains a phase in the form of a lamellar liquid crystal, comprising from 5 to 35 mass. % composition; the composition contains a phase in the form of particles, comprising from 25 to 55 mass. % composition.
EFFECT: creation of compositions of liquid detergents containing a smaller amount of hydroxyl-containing amino compounds, providing acceptable values of viscosities.
