Process for stabilizing solutions of peroxidic compounds used for bleaching. At least one polymer derived from an alpha-hydroxyacrylic acid, which contains units of the formula ##STR1## where R.sub.1 and R.sub.2 represent hydrogen or an alkyl group comprising from 1 to 3 carbon atoms which can be substituted by a hydroxyl group or a halogen atom, R.sub.1 and R.sub.2 being identical or different, and where M represents an alkali metal atom, a hydrogen atom or an ammonium group, is added to the solution as a stabilizer.

Particulate washing and bleaching compositions containing a peroxy compound and an alkali carbonate have their tendency to cake during storage reduced by incorporating within the compositions an alkaline aryl sulphonate, such as sodium methyl naphthalene sulphonate, and a water-insoluble inorganic compound, such as magnesium trisilicate. The compositions can be used for washing and bleaching textiles and fibers and cleaning hard surfaces.

Composition and process for washing and bleaching

Substituted anthraquinones are obtained by thermal or catalytic dehydrochlorination of the corresponding substituted ortho-benzoylbenzoic acid chloride. They may be used for the production of hydrogen peroxide and the synthesis of dyes.
