Abstract
An aqueous, isotropic liquid detergent composition comprising an aqueous solution of: PA0 a) an anionic surfactant; and PA1 b) an optical brightener of formula I ##STR1## in which X is hydrogen, NH.sub.4.sup..sym., or a cation of an alkali metal, an alkaline earth metal or an organic amine; PA0 R.sub.1 is selected from morpholino or anilino unsubstituted or substituted by 1, 2 or 3 groups selected from C.sub.1-4 alkyl, C.sub.1-4 alkoxy and halogen; piperidinyl, unsubstituted or substituted by 1 or 2 C.sub.1-4 alkyl groups; hexamethyleneimino, pyrrolidino, C.sub.1-8 alkylamino; C.sub.1-8 dialkylamino; or a 2,2,6,6-tetramethylpiperidinyl residue; PA0 R.sub.2 has a significance of R.sub.1 independently of R.sub.1 ; provided that when both groups R.sub.1 (or R.sub.2) are morpholino or unsubstituted anilino, the other groups R.sub.2 (or R.sub.1 respectively), are not both unsubstituted anilino.
