Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
A process for suppressing body odor in a warm-blooded animal comprising applying topically to said warm-blooded animal an effective deodorizing amount of a substantially anhydrous cosmetic preparation containing from 1 to 25% by weight based upon the total weight of at least one citrate ester of an acid selected from the group consisting of citric acid and acetylcitric acid with an alcohol selected from the group consisting of alkanol having from 1 to 6 carbon atoms, a cycloalkanol having from 5 to 6 carbon atoms and an alkanepolyol having 2 to 6 carbon atoms and 2 to 6 hydroxy groups; and the remainder of inert cosmetic ingredients.
Claim 2
Dependent Claim
107 words
A process for suppressing body odor in a warm-blooded animal comprising applying topically to said warm-blooded animal an effective deodorizing amount of a substantially anhydrous cosmetic preparation containing from 1 to 25% by weight based upon the total weight of at least one citrate ester of an acid selected from the group consisting of citric acid and acetylcitric acid with an alcohol selected from the group consisting of alkanol having from 1 to 6 carbon atoms, a cycloalkanol having from 5 to 6 carbon atoms and an alkanepolyol having 2 to 6 carbon atoms and 2 to 6 hydroxy groups; and the remainder of inert cosmetic ingredients.
Claim 3
Dependent Claim
17 words
The process of claim 1 wherein said citrate ester is esterified with 3 mols of said alcohol.
Claim 4
Dependent Claim
18 words
The process of claim 2 wherein said alcohol is an alkanol having from 1 to 6 carbon atoms.
Claim 5
Dependent Claim
23 words
The process of claim 1 wherein said preparation contains from 5 to 15% by weight based upon the total weight of said ester.
Claim 6
Dependent Claim
22 words

Claim 7
Dependent Claim
82 words
A process for suppressing body odor in a warm-blooded animal comprising applying topically to said warm-blooded animal an effective deodorizing amount of at least one citrate ester of an acid selected from the group consisting of citric acid and acetylcitric acid with an alcohol selected from the group consisting of alkanol having from 1 to 6 carbon atoms, a cycloalkanol having from 5 to 6 carbon atoms and an alkanepolyol having 2 to 6 carbon atoms and 2 to 6 hydroxy groups.
Claim 8
Dependent Claim
82 words
A process for suppressing body odor in a warm-blooded animal comprising applying topically to said warm-blooded animal an effective deodorizing amount of at least one citrate ester of an acid selected from the group consisting of citric acid and acetylcitric acid with an alcohol selected from the group consisting of alkanol having from 1 to 6 carbon atoms, a cycloalkanol having from 5 to 6 carbon atoms and an alkanepolyol having 2 to 6 carbon atoms and 2 to 6 hydroxy groups.
