Abstract
A composition and process for cleaning hard surfaces, the composition containing from 0.001 to 2% by weight, based on the weight of the composition, of a detergency booster comprising a copolymer of (a) from 20 to 80% by weight of esters selected from the group consisting of acrylic acid and methacrylic acid containing 1 to 4 carbon atoms in the alcohol component, and (b) from 20 to 80% by weight of acrylic acid or methacrylic acid, wherein the copolymer has an intrinsic viscosity of at least 200 ml.g.sup.-1 as measured in tetrahydrofuran at 20.degree. C.
Claims12
An aqueous composition for cleaning hard surfaces consisting of anionic or nonionic surfactants, water-soluble organic or inorganic builder components, water-soluble solvents or solubilizers, and from 0.001 to 2% by weight based on the weight of said composition, of a detergency booster consisting of a copolymer of
- (a) from 20 to 80% by weight of esters selected from the group consisting of acrylic acid and methacrylic acid containing 1 to 4 carbon atoms in the alcohol component, and
- (b) from 20 to 80% by weight of acrylic acid and methacrylic acid, said copolymer having an intrinsic viscosity of at least 200 ml.g.sup.-1 as measured in tetrahydrofuran at 20.degree. C.
The process of boosting the detergency of a hard surface cleaning composition consisting of anionic or nonionic surfactants, water-soluble organic or inorganic builder components, water-soluble solvents or solubilizers, comprising adding to said composition from 0.001 to 2% by weight, based on the weight of said composition, of a detergency booster consisting of a copolymer of
- (a) from 20 to 80% by weight of esters selected from the group consisting of acrylic acid and methacrylic acid containing 1 to 4 carbon atoms in the alcohol component, and
- (b) from 20 to 80% by weight of acrylic acid and methacrylic acid, said copolymer having an intrinsic viscosity of at least 200 ml.g.sup.-1 as measured in tetrahydrofuran at 20.degree. C.
