The invention relates to the liquid cleanser composition for individual use which contains: (a) from 15 to 50 wt% of fatty acylisethionate surfactant product containing from 10 to 50 wt% of fatty acids and/or fatty soaps and from 35 to 85 wt% of fatty acylisethionate in the said product, said product comprising at least 60% of total surfactant product (a) and cosurfactant (b) in the liquid composition (b) up to 15 wt% of optional cosurfactant selected from the group containing anionic, except fatty acylisethionate (a), amphoteric and nonionic surfactants and a mixture thereof, wherein the amount of said cosurfactant is up to 40 wt% of the total amount of fatty acylisethionate surfactant product (a) and cosurfactant (b) (c) from 1 to 16 wt% of an elevated temperature stabilizing system comprising: (i) from 0.1 to 8 wt% of a compound selected from the group consisting of alkanolamide, alkylamineoxide and a mixture of above (ii) from 0.3 to 8 wt% of a compound selected from the group consisting of C9 to C30 aliphatic hydrocarbon oils, ammonium salt, organic amine, linear C8 to C13 fatty acid/fatty alcohol, branched fatty acid and mixtures thereof, wherein the total amount of fatty alcohols and branched fatty acids is no more than 2 wt% in the liquid composition, wherein the ratio of fatty acylisethionate surfactant product (a) to cosurfactant (b) is in the range of 10/0 to 6/4 the viscosity of the said liquid cleanser composition at 0.01 s-1 is at least 250 Pa∙s and the ratio of the viscosity at 40°C to the viscosity at 25°C, when measured at 0.01 s-1, is at least 0.1. The invention also relates to a process for preparing a liquid cleansing composition for individual use.Изобретение относится к жидкой композиции очищающего средства для индивидуального применения, которая содержит: (a) от 15 до 50 мас.% жирного ацилизетионатного поверхностно-активного продукта, содержащего от 10 до 50 мас.% жирной кислоты и/или жирных мыл и от 35 до 85 мас.% жирного ацилизетионата в ука
