Abstract
Neutral to basic compositions comprising surfactants other than amphoteric surfactants, copolymers of vinylpyrrolidone and an alkylenically unsaturated monomer, and a polysaccharide polymer. Also, employment of these compositions in processes for treating hard surfaces, providing a shine benefit to the hard surfaces, reducing limescale deposits and watermarks from hard surfaces, and for providing a “next-time” cleaning benefit to hard surfaces.
Claims21
A liquid composition, having a pH of from 7 to 14, comprising a nonionic surfactant, a copolymer of N-vinylpyrrolidone and an alkylenically unsaturated monomer, and a polysaccharide polymer, wherein the composition is essentially free of any amphoteric surfactant.
A process for treating a hard surface to provide a shine benefit and/or to provide a long-lasting shine benefit to the hard surface, the process comprising:
- applying a composition comprising at least one nonionic surfactant, a copolymer of vinypyrrolidone and an alkylenically unsaturated monomer, and a polysaccharide polymer, to the hard surface.
A process for treating a hard surface to reduce the formation of limescale deposits and/or watermarks on the hard surface, the process comprising:
- applying a composition comprising at least one nonionic surfactant, a copolymer of vinypyrrolidone and an alkylenically unsaturated monomer, and a polysaccharide polymer, to the hard surface.
A process for treating a hard surface to provide a “next-time” cleaning benefit to the surface, the process comprising:
- applying a composition comprising at least one nonionic surfactant, a copolymer of vinypyrrolidone and an alkylenically unsaturated monomer, and a polysaccharide polymer, to the hard surface.
