Abstract
Abstract An aqueous composition for hard surface cleaning containing, by weight thereof, about 30% of an alkanolamine and about 0.8% of a water insolubilized polysaccharide having both hydroxyl and carboxyl groups, the ratio range of the free acid form to the salt form of the carboxyl groups being about 0.07/1 to 3/1. Preferably, the alkanolamine is monoethanolamine and the polysaccharide is a carboxyalkyl cellulose ether, such as a water insolubilized form of sodium carboxymethylcellulose. Preferably, the composition also contains about 0.5% of a fluorochemical and/or organo silicone type surfactant.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
86 words
A composition for hard surface cleaning consisting essentially of a minimum amount of about 5%, by weight thereof, of an alkanolamine selected from the group consisting of monoethanolamine, diethanolamine, triethanolamine, and mixtures thereof, an amount between about 0.3% and about 1.5%, by weight thereof, of a water insolubilized polysachharide having hydroxyl and carboxyl groups, the ratio range of the free acid form to the salt form of the carboxyl groups being about 0.07/1 to about 3/1, and up to about 93.5%, by weight thereof, of water.
Claim 2
Dependent Claim
86 words
A composition for hard surface cleaning consisting essentially of a minimum amount of about 5%, by weight thereof, of an alkanolamine selected from the group consisting of monoethanolamine, diethanolamine, triethanolamine, and mixtures thereof, an amount between about 0.3% and about 1.5%, by weight thereof, of a water insolubilized polysachharide having hydroxyl and carboxyl groups, the ratio range of the free acid form to the salt form of the carboxyl groups being about 0.07/1 to about 3/1, and up to about 93.5%, by weight thereof, of water.
