Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
An aerosol oxidation hair dyeing composition in an aerosol container under pressure wherein prior to release the composition is physically separated into mixtures A and B wherein: a. mixture A comprises a stabilized aqueous hydrogen peroxide solution comprising from about 10 to 20 weight percent of hydrogen peroxide, from about 0.25 to 1.4 weight percent of at least one monoterpenoid compound wherein the chemical structure of said compound is acyclic, monocyclic or bicyclic, and water wherein the pH of mixture A is about 2.5 to 4; and b. mixture B is an aerosol hair dye composition comprising a propellant blend and an aqueous oxidation hair dye concentrate, said concentrate containing at least one oxidation dye intermediate whose color is developable by means of an oxidizing agent, wherein the pH of mixture B is about 8 to 11.
Claim 2
Dependent Claim
137 words
An aerosol oxidation hair dyeing composition in an aerosol container under pressure wherein prior to release the composition is physically separated into mixtures A and B wherein: a. mixture A comprises a stabilized aqueous hydrogen peroxide solution comprising from about 10 to 20 weight percent of hydrogen peroxide, from about 0.25 to 1.4 weight percent of at least one monoterpenoid compound wherein the chemical structure of said compound is acyclic, monocyclic or bicyclic, and water wherein the pH of mixture A is about 2.5 to 4; and b. mixture B is an aerosol hair dye composition comprising a propellant blend and an aqueous oxidation hair dye concentrate, said concentrate containing at least one oxidation dye intermediate whose color is developable by means of an oxidizing agent, wherein the pH of mixture B is about 8 to 11.
Claim 3
Dependent Claim
34 words
The composition of claim 1 wherein said concentrate comprises about 90 to 97 weight per cent of mixture B and said propellant blend comprises about 3 to 10 weight per cent of mixture B.
Claim 4
Dependent Claim
23 words
The composition of claim 1 wherein said monoterpenoid compound is selected from the group consisting of d-limonene, myrcene, pinene, terpineol, ionone and carvone.
Claim 5
Dependent Claim
11 words
The composition of claim 3 wherein said monoterpenoid compound is d-limonene.
