Amphoteric polymer for treating hard surfaces

摘要

The present invention is directed to the use of hydrophilic terpolymers in hard surface cleaners which provide easier cleaning for surface soils such as hard water stains, soap scum, limescale, mud, food, toilet stains, oil, grease, particulates and the like as well as anti-fog effects on hard surfaces such as glass, mirrors, ceramic and plastic by causing water droplets to coalesce into a film.

主权项

1. A hard surface cleaning composition comprising about 0.01 to about 5 wt. % of a terpolymer formed from monomer components consisting of a), b) c) and optionally d)
wherein a) is defined as a monomer having the following structure (I): whereinR1 and R4 independently represent a hydrogen atom or a linear or branched C1-C6 alkyl group:R2 and R3 independently represent an alkyl, hydroxyalkyl or amino alkyl group in which the alkyl group is a linear or branched C1-C6 chain;n and m independently represent integers between 1 and 3;X− represents a counterion; b) at least one hydrophilic monomer bearing a function of acidic nature which is copolymerizable with (a) and capable of ionizing in the application medium and is selected the from group consisting of acrylic acid and methacrylic acid, c) is selected from the group consisting of acrylamide and methacrylamide; and d) optionally, a crosslinking agent, wherein monomer c) makes up at least 60 wt. % based on the total weight of the formed terpolymer wherein monomer a) will exceed the molar amount of component b) incorporated into the terpolymer by at least 10 molar% and an effective amount of a surfactant for improving cleaning performance.
