Abstract

Abstract A deodorant composition which prevents the formation of unpleasant odors due to bacterial decomposition of perspiration comprises a cosmetic carrier and, as the active component, a mixture of at least one weak organic acid and at least one salt of a weak organic acid and an aminated organic compound. The composition on application to the desired area of the body maintains the pH of the perspiration at a value of about 3 to 6.

Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 141 words
A deodorant composition for body hygiene to prevent the formation of unpleasant odors due to bacterial decomposition of perspiration, comprising a cosmetic carrier and essentially as the active component in said composition a mixture of at least one weak organic acid and at least one salt of a weak organic acid and an aminated organic compound, said weak organic acid having the formula C n H m (OH) x (COOH) y wherein n is 0 or a whole number from 1 to 6, m is a whole number from 1 to 8, x is 0, 1 or 2 and y is 1, 2 or 3 and having a molecular weight not exceeding 192, the said mixture on application to the selected areas of the body maintains the pH of the perspiration at a value approximately fixed between about 3 to 6.
Claim 2
Dependent Claim 141 words
A deodorant composition for body hygiene to prevent the formation of unpleasant odors due to bacterial decomposition of perspiration, comprising a cosmetic carrier and essentially as the active component in said composition a mixture of at least one weak organic acid and at least one salt of a weak organic acid and an aminated organic compound, said weak organic acid having the formula C n H m (OH) x (COOH) y wherein n is 0 or a whole number from 1 to 6, m is a whole number from 1 to 8, x is 0, 1 or 2 and y is 1, 2 or 3 and having a molecular weight not exceeding 192, the said mixture on application to the selected areas of the body maintains the pH of the perspiration at a value approximately fixed between about 3 to 6.
Claim 3
Dependent Claim 38 words
The composition of claim 1 wherein said weak organic acid is selected from the group consisting of formic acid, acetic acid, citric acid, malic acid, lactic acid, tartaric acid, adipic acid, phthalic acid, salicylic acid and succinic acid.
Claim 4
Dependent Claim 26 words
The composition of claim 1 wherein said aminated organic compound is a mono- functional compound or pluri-functional compound having a primary, secondary or tertiary amine function.
Claim 5
Dependent Claim 32 words
The composition of claim 1 wherein said aminated organic compound is an amino alcohol selected from the group consisting of 2-amino-2-methyl propanol-1, 2-amino-2-methyl-1,3-propanediol, monoethanolamine, diethanolamine, triethanolamine and mono- isopropanolamine di-isopropanolamine and tri-isopropanolamine.
Claim 6
Dependent Claim 25 words

The composition of claim 1 wherein the pH transmitted to the perspiration is approximately equal to the pK of the weak organic acid present in said active component mixture.
Claim 10
Dependent Claim 30 words
The composition of claim 1 wherein said active component mixture is present in an amount from 0.5 to 15 percent by weight relative to the total weight of said composition.
Claim 11
Dependent Claim 17 words

Claim 16
Dependent Claim 60 words
A process for preventing the formation of unpleasant odors due to bacterial decomposition of perspiration, comprising applying to the axillary, inguinal or interdigital areas of the body, an effective deodorant amount of the composition of claim 1 so as to maintain the pH of the perspiration at a value between about 3 to 6 for a prolonged period of time.
Claim 17
Dependent Claim 28 words
