The invention relates to diacids resulting from tetrahydrophthalic acid (chlorendic acid). The diacids correspond to the formula ##STR1## in which R represents the radical ##STR2## or the radical ##STR3## They are prepared using an excess of chlorendic acid. They can be used as fireproofing additives for polymeric materials or as prepolymers for polycondensation reactions.

Chlorobromodicarboxylic acids and processes for their manufacture and

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.sub.1 and R.sub.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.
