Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
37 words
A method for reducing the volume of perspiration produced which comprises applying to the epidermal surface area where reduction in volume of perspiration is desired, a perspiration volume reducing amount of a substantially water-insoluble aldehyde polysaccharide compound.
Claim 2
Independent Claim
37 words
A method for reducing the volume of perspiration produced which comprises applying to the epidermal surface area where reduction in volume of perspiration is desired, a perspiration volume reducing amount of a substantially water-insoluble aldehyde polysaccharide compound.
Claim 3
Dependent Claim
18 words
A method according to claim 1 in which the aldehyde polysaccharide compound is at least 10 percent oxidized.
Claim 4
Dependent Claim
34 words
A method according to claim 1 in which the aldehyde polysaccharide compound is one which has been prepared from a polysaccharide having a degree of polymerization of at least 400 repeating units per molecule.
Claim 5
Dependent Claim
30 words
A method according to claim 1 wherein the aldehyde polysaccharide compound is applied in an amount sufficient to supply 0.02 mg. to 1 mg. per square cm. of epidermal surface.
Claim 6
Dependent Claim
16 words
A method according to claim 1 in which the aldehyde polysaccharide compound is a dialdehyde starch.
Claim 7
Dependent Claim
16 words
A method according to claim 1 in which the aldehyde polysaccharide compound is a dialdehyde cellulose.
Claim 8
Dependent Claim
35 words
A method according to claim 1 in which the aldehyde polysaccharide compound is supplied in a composition containing said aldehyde polysaccharide compound in an amount of at least 0.5 percent by weight of ultimate composition.
Claim 9
Dependent Claim
33 words
A method according to claim 1 in which the aldehyde polysaccharide compound is present in the composition in an amount sufficient to supply at least 0.2 percent by weight of the aldehyde group.
