Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
78 words
An antiperspirant solution suitable for pump spray or roll-on application consisting essentially of an alcohol soluble aluminum chlorhydroxide complex; a sufficient amount of a polydimethyl siloxane of the structural formula ##STR2## to substantially reduce the tackiness of said complex during drying; and a sufficient amount of alcohol to result in said solution; said composition being characterized by having substantially reduced tackiness and giving a preception of quick drying when applied from a pump spray or a roll-on applicator.
Claim 2
Dependent Claim
78 words
An antiperspirant solution suitable for pump spray or roll-on application consisting essentially of an alcohol soluble aluminum chlorhydroxide complex; a sufficient amount of a polydimethyl siloxane of the structural formula ##STR2## to substantially reduce the tackiness of said complex during drying; and a sufficient amount of alcohol to result in said solution; said composition being characterized by having substantially reduced tackiness and giving a preception of quick drying when applied from a pump spray or a roll-on applicator.
Claim 3
Dependent Claim
28 words
An antiperspirant solution as defined in claim 1 having a gel inhibitor incorporated into said solution in an amount sufficient to substantially reduce gelling thereof upon extended aging.

An antiperspirant solution as defined in claim 6 wherein said complex is a 1,2-propylene glycol complex of aluminum chlorhydroxide.
Claim 9
Dependent Claim
32 words
An antiperspirant solution as defined in claim 6 wherein said gel inhibitor is selected from the group consisting of triple pressed stearic acid, isostearic acid, hexadecyl alcohol, oleyl alcohol and mixtures thereof.
Claim 10
Dependent Claim
78 words
An antiperspirant solution as defined in claim 1 consisting of: a. 15% by weight of an aluminum chlorhydroxide complex having the formula Al 2 (H 2 O) 0 .7-l1.1 (OH) 4 .9-5.1 (Cl) 0 .1-1.1 (1,2-propylene glycol) 0 .7-1.3, b. 1.5% by weight of triple pressed stearic acid; c. 1.0% by weight of isopropyl myristate; d. 15% by weight of polydimethylsiloxane of the structural formula ##STR4## e. 0.5% by weight of perfume; and f. 67% by weight ethanol.
Claim 11
Dependent Claim
18 words

Claim 13
Independent Claim
59 words
A method for substantially reducing the tackiness during drying and giving the perception of being quick drying of an alcohol solution of an alcohol soluble aluminum chlorhydroxide complex comprising introducing into said solution a sufficient amount of a polydimethyl siloxane of the structural formula ##STR5## to result in said substantial reduction of tackiness, and said perception of quick drying.
Claim 14
Independent Claim
