POWDERY DETERGENT COMPOSITION

摘要

Disclosed is a powdery detergent composition comprising the following components (A) and (B). Component (A): at least one member selected from dimethyl polysiloxane and a derivative thereof. Component (B): a polysaccharide derivative which is substituted by a group represented by the general formula (I) [wherein a hydrogen atom in a hydroxy group as the substituent of the general formula (I) may be substituted by the substituent of the formula (I)], which has 1 to 100 pieces of the substituent per 1000 monosaccharide units, and which has a weight average molecular weight of 1,000 to 5,000,000. Formula (I): -E1-(OA)n-E2-R wherein E1 represents a linear or branched bivalent saturated hydrocarbon group having 1 to 6 carbon atoms which may be substituted by a hydroxy or oxo group; n represents a numerical number of 0 to 300; n pieces of A independently represent a linear or branched bivalent saturated hydrocarbon group having 1 to 6 carbon atoms; E2 represents an ether bond or an oxycarbonyl group (-OCO- or -COO-); and R represents a linear or branched alkyl group having 4 to 30 carbon atoms which may be substituted by a hydroxy group.
