Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
109 words
HYDROGEN PEROXIDE CONTAINING ABOUT 1 TO ABOUT 100 MILLIGRAMS OF A WATER-SOLUBLE ORGANIC CHELATING AGENT HAVING AT LEAST ONE TRIVALENT NITROGEN ATOM TO WHICH ARE ATTACHED AT LEAST TWO CARBOXYL GROUPS WHICH ARE EACH LINKED TO SAID NITROGEN ATOM BY A SATURATED ALIPHATIC HYDROCARBON GROUP OF NOT MORE THAN TWO CARBON ATOMS, PER LITER OF HYDROGEN PEROXIDE, TOGETHER WITH FROM ABOUT 1 TO 2 TIMES THE STOICHIOMETRIC AMOUNT, BASED ON THE CHELATING AGENT, OF A WATER-SOLUBLE ALUMINUM COMPOUND FOR COMPLEXING WITH SAID CHELATING AGENT, AND AN AMOUNT OF WATERSOLUBLE PHOSPHATE BETWEEN ABOUT 25 MILLIGAMS PER LITER OF HYDROGEN PEROXIDE AND THE SOLUBILITY LIMIT OF SAID PHOSPHATE IN HYDROGEN PEROXIDE.
Claim 2
Dependent Claim
109 words
HYDROGEN PEROXIDE CONTAINING ABOUT 1 TO ABOUT 100 MILLIGRAMS OF A WATER-SOLUBLE ORGANIC CHELATING AGENT HAVING AT LEAST ONE TRIVALENT NITROGEN ATOM TO WHICH ARE ATTACHED AT LEAST TWO CARBOXYL GROUPS WHICH ARE EACH LINKED TO SAID NITROGEN ATOM BY A SATURATED ALIPHATIC HYDROCARBON GROUP OF NOT MORE THAN TWO CARBON ATOMS, PER LITER OF HYDROGEN PEROXIDE, TOGETHER WITH FROM ABOUT 1 TO 2 TIMES THE STOICHIOMETRIC AMOUNT, BASED ON THE CHELATING AGENT, OF A WATER-SOLUBLE ALUMINUM COMPOUND FOR COMPLEXING WITH SAID CHELATING AGENT, AND AN AMOUNT OF WATERSOLUBLE PHOSPHATE BETWEEN ABOUT 25 MILLIGAMS PER LITER OF HYDROGEN PEROXIDE AND THE SOLUBILITY LIMIT OF SAID PHOSPHATE IN HYDROGEN PEROXIDE.
Claim 3
Independent Claim
92 words
A METHOD OF STABILIZING HYDROGEN PEROXIDE WHICH COMPRISES ADDING TO THE PERIOXIDE ABOUT 1 TO ABOUT 1000 MILLIGRAMS PER LITER OF A WATER-SOLUBLE ORGANIC CHELATING AGENT HAVING AT LEAST ONE TRIVALENT NITROGEN ATOM TO WHICH ARE ATTACHED AT LEAST TWO CARBOXYL GROUPS WHICH ARE EACH LINKED TO SAID NITROGEN ATOM BY A SATURATED ALIPHATIC HYDROCARBON GROUP OF NOT MORE THAN TWO CARBON ATOMS TOGETHER WITH SUFFICIENT WATER SOLUBLE ALUMINUM COMPOUND TO FORM A COMPLEX WITH SAID CHELATING AGENT AND BETWEEN ABOUT 50 AND ABOUT 500 MILLIGRAMS PER LITER OF A SOLUBLE PHOSPHATE.
Claim 4
Independent Claim
92 words
A METHOD OF STABILIZING HYDROGEN PEROXIDE WHICH COMPRISES ADDING TO THE PERIOXIDE ABOUT 1 TO ABOUT 1000 MILLIGRAMS PER LITER OF A WATER-SOLUBLE ORGANIC CHELATING AGENT HAVING AT LEAST ONE TRIVALENT NITROGEN ATOM TO WHICH ARE ATTACHED AT LEAST TWO CARBOXYL GROUPS WHICH ARE EACH LINKED TO SAID NITROGEN ATOM BY A SATURATED ALIPHATIC HYDROCARBON GROUP OF NOT MORE THAN TWO CARBON ATOMS TOGETHER WITH SUFFICIENT WATER SOLUBLE ALUMINUM COMPOUND TO FORM A COMPLEX WITH SAID CHELATING AGENT AND BETWEEN ABOUT 50 AND ABOUT 500 MILLIGRAMS PER LITER OF A SOLUBLE PHOSPHATE.
