Abstract
Composition for cleaning or rinsing hard surfaces in an aqueous or aqueous/alcoholic medium comprising at least one polybetaine for contributing to said surfaces antideposition and/or antiadhesion properties with regard to soiling substances capable of being deposited on said surface.
Claims28
A process of cleaning or rinsing a hard surface, comprising the step of treating a hard surface with a composition comprising in an aqueous or aqueous/alcoholic medium at least one surfactant and at least one polybetaine (B) comprising:
- a homopolymer comprising betaine units comprising (-SPE-), (-SPP-), (-SHPE-), or (-SHPP-);
- a copolymer comprising at least two different hetaine units of formulae (-SPE-), (-SPP-) (-SHPE-) or (-SHPP-);
- a copolymer comprising identical or different betaine units of formulae (-SPE-), (-SPP-), (-SHPE-) or (-SHPP-) and methacrylic acid units,
- wherein the amount of methacrylic acid units is less than 50 mol % of said copolymers;
- or
- mixtures thereof.
A process of preventing the redeposition or adhesion of soiling substances on a hard surface, comprising the step of:
- treating said hard surface with a composition comprising in an aqueous or aqueous/alcoholic medium at least one surfactant and at least one polybetaine (B) comprising:
- a homopolymer comprising betaine units comprising (-SPE-), (-SPP-), (-SHPE-), or (-SHPP-);
- a copolymer comprising at least two different betaine units of formulae (-SPE-), (-SPP-), (-SHPE-) or (-SHPP-);
- a copolymer comprising identical or different betaine units of formulae (-SPE-), (-SPP-), (-SHPE-) or (-SHPP-) and methacrylic acid units,
- wherein the amount of methacrylic acid units is less than 50 mol % of said copolymers;
- or
- mixtures thereof.
