Abstract

Abstract A microbially self-decontaminating dermatological cleansing concentrate containing at least one washing-active surfactant and at least one standard cleansing concentrate additive, and having a viscosity of about 500 to 5,000 mPas, improved by incorporating hydrogen peroxide, at least one fatty acid alkanolamide, and at least one water soluble alkali salt or ammonium salt; and a method for its use.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 201 words
In a water-miscible dermatological cleansing concentrate consisting essentially of about 5 to 15 wt% of at least one washing-active surfactant which is an alkylether sulfate, an amide ether sulfate, a sulfosuccinic acid ester, or a protein-fatty acid condensate, in the form of their Na or NH 4 salts; about 0.5 to 5 wt% of at least one standard cleansing concentrate additive; and having a viscosity of about 500 to 5,000 mPas, the improvement of rendering said cleansing concentrate microbially self-decontaminating while maintaining its viscosity and water miscibility by incorporating therein ingredients consisting of: (A) about 0.05 to 2 wt% of hydrogen peroxide; (B) about 0.2 to 5 wt% of a fatty acid alkanolamide which is a combination of coconut oil fatty acid diethanolamide and oleic acid diethanolamide in a weight ratio of about 0.2-5:1; (C) about 0.5 to 3 wt% of at least one water-soluble salt, which is ammonium sulfate; sodium chloride, potassium chloride, sodium sulfate, or potassium citrate; and (D) at least one standard cosmetic preservative, either not present or present in at least a minimally preservative-effective amount, all wt% being based upon the total formulation weight, and wherein said viscosity is maintained after incorporating all of the above ingredients.
Claim 2
Dependent Claim 201 words
In a water-miscible dermatological cleansing concentrate consisting essentially of about 5 to 15 wt% of at least one washing-active surfactant which is an alkylether sulfate, an amide ether sulfate, a sulfosuccinic acid ester, or a protein-fatty acid condensate, in the form of their Na or NH 4 salts; about 0.5 to 5 wt% of at least one standard cleansing concentrate additive; and having a viscosity of about 500 to 5,000 mPas, the improvement of rendering said cleansing concentrate microbially self-decontaminating while maintaining its viscosity and water miscibility by incorporating therein ingredients consisting of: (A) about 0.05 to 2 wt% of hydrogen peroxide; (B) about 0.2 to 5 wt% of a fatty acid alkanolamide which is a combination of coconut oil fatty acid diethanolamide and oleic acid diethanolamide in a weight ratio of about 0.2-5:1; (C) about 0.5 to 3 wt% of at least one water-soluble salt, which is ammonium sulfate; sodium chloride, potassium chloride, sodium sulfate, or potassium citrate; and (D) at least one standard cosmetic preservative, either not present or present in at least a minimally preservative-effective amount, all wt% being based upon the total formulation weight, and wherein said viscosity is maintained after incorporating all of the above ingredients.
Claim 3
Dependent Claim 34 words

Claim 4
Dependent Claim 13 words
The concentrate of claim 2 wherein (B) is present in about 2 wt%.
Claim 5
Dependent Claim 13 words
The concentrate of claim 2 wherein (C) is present in about 2 wt%.
Claim 6
Dependent Claim 21 words
The concentrate of claim 2 wherein (D) is present in up to about 2 times the amount of (A), by weight.
Claim 7
Dependent Claim 15 words
The concentate of claim 1 wherein (A) is present in about 0.2 to 1 wt%.
Claim 8
Dependent Claim 13 words
The concentrate of claim 1 wherein (b) is present in about 2 wt%.
Claim 9
Dependent Claim 13 words
The concentrate of claim 1 wherein (C) is present in about 2 wt%.
Claim 10
Dependent Claim 26 words
The concentrate of claim 1 wherein (B) is a combination of coconut oil fatty acid diethanolamide and oleic acid ethanolamide, each present in about 1 wt%.
Claim 11
Dependent Claim 16 words
The concentrate of claim 1 wherein (B) and (C) together comprise up to about 4 wt%.
Claim 12
Dependent Claim 21 words
The concentrate of claim 1 wherein (D) is present in up to about 2 times the amount of (A), by weight.
Claim 13
Dependent Claim 15 words
The concentrate of claim 1 having an initial viscosity of about 500 to 4,000 mPas.
Claim 14
Dependent Claim 23 words
A method for cleansing hands comprising applying thereto the concentrate of claim 1 in a cleansing-effective amount, and rinsing the hands with water.
Claim 15
Dependent Claim 23 words
A method for cleansing hands comprising applying thereto the concentrate of claim 2 in a cleansing-effective amount, and rinsing the hands with water.
Claim 16
Dependent Claim 23 words
A method for cleansing hands comprising applying thereto the concentrate of claim 7 in a cleansing-effective amount, and rinsing the hands with water.
Claim 17
