FIELD: chemistry.
SUBSTANCE: group of inventions relates to a detergent. A composition of a detergent for clothes contains modified hydroxyalkylcellulose and at least one substance selected from an anionic or non-ionic surfactant, wherein hydroxyalkylcellulose is a component, in which a cation group and a hydrophobic group represented by the formula (1): 
are bound to a group formed by substitution of a hydrogen atom in a hydroxyl group of hydroxyalkylcellulose, where Z is a single bond or a hydrocarbon group having an oxygen atom; R1 is a hydrocarbon group with 6-24 carbon atoms, and * is a position of binding with a group formed by substitution of a hydrogen atom in a hydroxyl group of hydroxyalkylcellullose, where the cation group includes a quaternary ammonium cation, an average-weighted molecular weight of hydroxyalkylcellulose is 1000-3,000,000, the mass ratio of the total content of the anionic and non-ionic surfactant to the content of modified hydroxyalkylcellulose is 0.1-2000. The use of a composition as a detergent composition, in particular for a hydrophobic surface, is also disclosed.
EFFECT: group of inventions provides for enhancing a detergent for dirt removal.
