Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
30 words
A stabilized peroxide composition comprising or consisting essentially of a peroxygen component, a metal chelating agent and water, characterized in that there is also present a free radical scavenging agent.
Claim 2
Dependent Claim
30 words

Claim 3
Dependent Claim
45 words
A stabilized liquid peroxide bleaching composition comprising an aqueous composition of a peroxygen component, a metal chelating agent and an organic component selected from nonionic surfactants, fluorescent whiteners, a dye, and mixtures thereof, characterized in that there is also present a free radical scavenging agent.
Claim 4
Dependent Claim
45 words
A stabilized liquid peroxide bleaching composition comprising an aqueous composition of a peroxygen component, a metal chelating agent and an organic component selected from nonionic surfactants, fluorescent whiteners, a dye, and mixtures thereof, characterized in that there is also present a free radical scavenging agent.

Independent Claim
32 words
A method for stabilizing peroxide based oxidizing or bleaching compositions comprising admixing into said compositions a metal chelating agent, characterized in that there is also admixed therein a free radical scavenging agent.
Claim 9
Independent Claim
32 words
A method for stabilizing peroxide based oxidizing or bleaching compositions comprising admixing into said compositions a metal chelating agent, characterized in that there is also admixed therein a free radical scavenging agent.
Claim 10
Independent Claim
43 words
A method for stabilizing organic components of liquid peroxide bleaching formulations into which said organic components have been mixed, comprising admixing into said peroxide bleaching formulations a metal chelating agent, characterized in that there is also admixed therein a free radical scavenging agent.
Claim 11
Independent Claim
43 words
A method for stabilizing organic components of liquid peroxide bleaching formulations into which said organic components have been mixed, comprising admixing into said peroxide bleaching formulations a metal chelating agent, characterized in that there is also admixed therein a free radical scavenging agent.
