Abstract
This invention relates to colored acidic thickened aqueous compositions comprising a source of peroxygen and from 0.002% to 0.05% by weight of the total composition of an .alpha. or .beta. metal phthalocyanine dye, or mixtures thereof. Preferred compositions therein comprise a thickening surfactant system such as a quaternary ammonium compound together with a short chain amine oxide. Said compositions are particularly suitable for the cleaning of toilet bowls providing enhanced perceived viscosity by the consumer and enhanced ease of rinsing perceived by the consumer.
