Abstract
A polyacrylic resin which can be a polyacrylic acid or a mixture of a polyacrylic acid and an acrylic polymeric complex with a phosphinate or sulfur containing moiety is used as a builder in an aqueous glass cleaning composition of the spray-on wipe-off type containing an organic solvent system and at least one detergent surface active agent. Cleaning efficiency is comparable to and even superior to tetrasodium pyrophosphate built compositions.
Claims29
An aqueous composition for cleaning glass and similar hard surfaces comprising an aqueous solution of
- (a) about 0.5-8% of at least one lower aliphatic monohydric alcohol having about 2-4 carbon atoms and a boiling point not in excess of about 100.degree. C.;
- (b) about 0.5-5% of at least one higher boiling polar organic solvent selected from the group consisting of glycols having from 2-6 carbon atoms and 1-4 carbon alkyl ethers of a glycol containing a total of about 3-8 carbon atoms and having a boiling point not in excess of about 250.degree. C.;
- (c) about 0.05-5% of at least one surface active agent compatible with components (a) and (b) and selected from the group consisting of water soluble anionic and non-ionic surface active agents;
- and
- (d) about 0.005 to 2.0% of a low molecular weight polyacrylic resin comprising polyacrylic acids and the corresponding alkali metal, ammonium and amine salts thereof characterized by the formula ##STR7## wherein R.sub.1 is hydrogen or methyl, and x is a number of from about 10 to about 100, the weight average molecular weight being between about 500 to about 8000;
- all percentages being by weight, and water being the balance.

- with an acrylic polymer complex of the type ##STR9## and the corresponding alkali metal, ammonium and amine salts thereof, where R.sub.1 is as previously defined, and M's are independently a hydrogen atom or a member selected from the group consisting of alkali metal, ammonium and amino cations, and y is from about 5 to about 60, the ratio of said polyacrylic acid to the acrylic polymeric complex being on a weight basis between about 1:1 to about 15:1;
- all percentages being by weight, and water being the balance.
