Abstract
A process and surfactant-containing composition for reducing incrustation on washed laundry. The composition contains finely-divided, water-insoluble builder components and an at least partly water-soluble co-builder which is the oxidation product of polyglucosans wherein, on average, at least 15 mole percent thereof consists of oxidized anhydroglucose units corresponding to formula I ##STR1## and which have an average molecular weight of up to 15,000.
Claims21
A surfactant-containing detergent composition comprising finely-divided, water-insoluble builder components and from 0.5% to 15% by weight, based on the weight of said composition, of an at least partly water-soluble co-builder, said co-builder comprising the oxidation products of polyglucosans wherein, on average, at least 15 mole percent thereof consists of oxidized anhydroglucose units corresponding to formula I ##STR3## and which have an average molecular weight of up to 15,000.
The process of reducing incrustation on laundry, comprising washing said laundry with a phosphate-free detergent composition comprising finely-divided, water-insoluble builder components and from 0.5% to 15% by weight, based on the weight of said composition, of an at least partly water-soluble co-builder, said co-builder comprising the oxidation products of polyglucosans wherein, on average, at least 15 mole percent thereof consists of oxidized anhydroglucose units corresponding to formula I ##STR4## and which have an average molecular weight of up to 15,000.
