Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
65 words
A preparation for the bleaching of hair consisting essentially of: A. 0.05% to 10% by weight of keratose, B. 3% to 10% by weight of at least one oxidizing agent for liberating active oxygen, calculated as hydrogen peroxide, and C. the balance being an ingredient selected from the group consisting of a wetting agent, a thickening agent, a pH adjustment reagent, water, and mixtures thereof
Claim 2
Dependent Claim
65 words
A preparation for the bleaching of hair consisting essentially of: A. 0.05% to 10% by weight of keratose, B. 3% to 10% by weight of at least one oxidizing agent for liberating active oxygen, calculated as hydrogen peroxide, and C. the balance being an ingredient selected from the group consisting of a wetting agent, a thickening agent, a pH adjustment reagent, water, and mixtures thereof
Claim 3
Dependent Claim
21 words
The preparation of claim 1, wherein the weight of said keratose is 3% to 7% of the weight of said preparation.
Claim 4
Dependent Claim
12 words
The preparation of claim 1, wherein said oxidizing agent is hydrogen peroxide.
Claim 5
Dependent Claim
36 words
The preparation of claim 1 wherein said oxidizing agent is selected from the group consisting of hydrogen peroxide, percarbamide, an alkali metal perborate, an alkali metal percarbonate, melamine perhydrate, an alkali metal persulfate and mixtures thereof.
Claim 6
Dependent Claim
61 words
In a process for bleaching hair which comprises applying a bleaching agent containing an oxidizing agent to the hair at a temperature and for a time effective to bleach said hair, and removing said agent from the hair; the improvement which consists essentially in utilizing from 0.05% to 10% by weight of keratose in said bleaching agent containing an oxidizing agent.
Claim 7
Dependent Claim
61 words
In a process for bleaching hair which comprises applying a bleaching agent containing an oxidizing agent to the hair at a temperature and for a time effective to bleach said hair, and removing said agent from the hair; the improvement which consists essentially in utilizing from 0.05% to 10% by weight of keratose in said bleaching agent containing an oxidizing agent.
Claim 8
Dependent Claim
42 words
A process for the bleaching of human hair consisting essentially of applying to said hair at a temperature ranging from about 15°C to 40°C for a time sufficient to bleach said hair, an effective amount of the preparation according to claim 1.
Claim 9
Dependent Claim
20 words
The process of claim 6, wherein the weight of keratose is 3% to 7% of the weight of said preparation.
Claim 10
Dependent Claim
12 words
The process of claim 6 wherein said oxidizing agent is hydrogen peroxide.
Claim 11
Dependent Claim
36 words
The process of claim 6 wherein said oxidizing agent is selected from the group consisting of hydrogen peroxide, percarbamide, an alkali metal perborate, an alkali metal percarbonate, melamine perhydrate, an alkali metal persulfate, and mixtures thereof.
