Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
A cleaning and fire-proofing composition comprising the reaction product of: a. 40-60 parts by weight of a polyalkanol amine; b. 30-50 parts by weight of phosphoric acid; c. 35-60 parts by weight of a fire-proofing agent selected from the group consisting of monoammonium phoshate, diammonium phoshate and ammonium salts of sulfamic acid; d. 1-30 parts by weight of a detergent selected from the group consisting of alkali metal derivatives of aryl sulfonic acids, alkali metal alkyl sulfates, alkali metal alkyl sulfonates, alkali metal and ammonium salts of ethanolamine, the monoethers of polyethylene glycol which contain a long chain lipophile group, the higher alkyl phenol polylower alkoxy alkanols, alkali metal phosphates, and mixtures thereof; and e. 250-550 parts by weight of water; said composition having a pH in the range of 5.5 to 6.5.
Claim 2
Dependent Claim
