Abstract
Abstract A stable liquid detergent composition comprises a peroxide derivative, at least one surface-active agent, a salt of a polymer derived from an alpha-hydroxyacrylic acid, which salt contains units of the formula ##STR1## wherein R 1 and R 2 independently represent hydrogen atoms or alkyl groups containing from 1 to 3 carbon atoms which may or may not be substituted and where M represents a cationic radical resulting from the dissociation of a base, and at least one solvent.

Claim 1
Independent Claim
153 words
A stable liquid detergent composition made of an equeous solvent and from 5 to 60% by weight of active constitutents comprising (a) a peroxidic compound selected from the group consisting of hydrogen peroxide and the organic and inorganic addition products of hydrogen peroxide, with the concentration of alkali metal ions in the free state not exceeding 10 g per kg of solvent, (b) at least one surface-active agent and (c) a stabilizer which is a salt, of an organic or inorganic base and of a polymer derived from an alpha-hydroxyacrylic acid, which salt contains units of the formula ##STR4## where R 1 and R 2 independently represent hydrogen atoms or alkyl groups containing from 1 to 3 carbon atoms which may or may not be substituted and where M represents a cationic radical resulting from the dissociation of said base, with the average molecular weight of the polymer being greater than about 300.
Claim 2
Dependent Claim
