Abstract
Abstract Phase, stable, hard surface cleaners are provided comprising an acidic aqueous phase in which a linear alkyl aryl sulfonic acid and an alkali metal peroxymonosulfate are dissolved. The former component can provide improved chemical stability of the solubilized peroxymonosulfate, and the two components, when present in sufficient amounts, result in a flowable, plastic liquid which is capable of stably suspending abrasives.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
A liquid hard surface cleaner comprising: a single-phase, substantially phase stable aqueous solution, said aqueous solution having linear alkyl aryl sulfonic acid and potassium peroxymonosulfate dissolved therein, said potassium peroxymonosulfate having a determinable chemical stability, said linear alkyl aryl sulfonic acid in an amount not greater than about 10 wt. % and with a weight ratio with respect to said potassium peroxymonosulfate of from about 1:0.05 to about 0.05:1, the aqueous solution having a pH of about 1 to about 1.5, said amount of linear alkyl aryl sulfonic acid being effective to increase the chemical stability of said potassium peroxymonosulfate with respect to the determinable chemical stability thereof.
Claim 2
Dependent Claim
108 words
A liquid hard surface cleaner comprising: a single-phase, substantially phase stable aqueous solution, said aqueous solution having linear alkyl aryl sulfonic acid and potassium peroxymonosulfate dissolved therein, said potassium peroxymonosulfate having a determinable chemical stability, said linear alkyl aryl sulfonic acid in an amount not greater than about 10 wt. % and with a weight ratio with respect to said potassium peroxymonosulfate of from about 1:0.05 to about 0.05:1, the aqueous solution having a pH of about 1 to about 1.5, said amount of linear alkyl aryl sulfonic acid being effective to increase the chemical stability of said potassium peroxymonosulfate with respect to the determinable chemical stability thereof.
Claim 3
Dependent Claim
37 words
The liquid hard surface cleaner as in claim 1 wherein said amount of linear alkyl aryl sulfonic acid is effective in increasing the chemical stability of said potassium peroxymonosulfate with respect to the determinable chemical stability thereof.
