Abstract
Abstract A water based cleaning composition including a major portion of water, a minor portion of a cleaning agent such as ammonium hydroxide or a lower alcohol such as isoproponal and a small portion of a polyethylene glycol of high molecular weight which not only acts as a lubricant but has a preferential affinity for glass and the like as compared with oil, grease, dirt and/or a lubricity component such as ammonium bicarbonate or ammonium carbonate.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
154 words
A water based cleaning composition consisting essentially of water on the order of about 59.3 to about 99.58 weight percent, a cleaning agent selected from the group consisting of ammonium hydroxide, a monohydroxy alcohol containing not more than 3 carbon atoms and mixtures thereof on the order of about 0.31 to about 40.3 weight percent plus an amount of at least one lubricity compound selected from the group consisting of a water soluble polymer of ethylene glycol having at least 16 carbon atoms according to the formula ROCH 2 (CH 2 OCH 2 ) n CH 2 OR having a molecular weight of at least 380 wherein n is at least seven and R is a radical selected from the group consisting of H + and CH 3 + ammonium carbonate, ammonium bicarbonate and mixtures thereof on the order of about 0.025 to about 0.3 weight percent to impart substantial lubricity to the composition.
Claim 2
Dependent Claim
154 words
A water based cleaning composition consisting essentially of water on the order of about 59.3 to about 99.58 weight percent, a cleaning agent selected from the group consisting of ammonium hydroxide, a monohydroxy alcohol containing not more than 3 carbon atoms and mixtures thereof on the order of about 0.31 to about 40.3 weight percent plus an amount of at least one lubricity compound selected from the group consisting of a water soluble polymer of ethylene glycol having at least 16 carbon atoms according to the formula ROCH 2 (CH 2 OCH 2 ) n CH 2 OR having a molecular weight of at least 380 wherein n is at least seven and R is a radical selected from the group consisting of H + and CH 3 + ammonium carbonate, ammonium bicarbonate and mixtures thereof on the order of about 0.025 to about 0.3 weight percent to impart substantial lubricity to the composition.
