  • Liquid acidic limescale removal composition packaged in a spray-type dispenser
    Patent number: 6333299
    Abstract: The present invention relates to liquid acidic compositions suitable for removing limescale-containing stains from a hard-surface, comprising an acid, from 0.001% to 20% by weight of the total composition of a polysaccharide polymer and from 0.001% to 20% by weight of the total composition of a vinylpyrrolidone homopolymer or copolymer, said composition being packaged in a spray type-dispenser. Such a composition provides improved shine to the surface treated while exhibiting effective limescale removal performance. The use of a polysaccharide polymer and a vinylpyrrolidone homopolymer or copolymer, in a liquid acidic composition being packaged in a spray-type dispenser, to treat a hard-surface, reduces or even prevents the formation of watermarks and even limescale deposits on said hard-surface after said hard-surface has first been treated with said composition and subsequently comes in contact with water.

  • Colored acidic aqueous liquid compositions comprising a peroxy-bleach
    Patent number: 5910473
    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.
