Abstract
Abstract A formulation and method for a pump spray or roll-on antiperspirant is disclosed which antiperspirant is characterized by having superior drying properties while substantially eliminating clogging of the valve or roll-ball. The formulation comprises one or more alcohol soluble aluminum chlorhydroxide compounds in combination with an alcohol vehicle and selected silicone liquids.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
95 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 polyorgano-siloxane selected from the group consisting of polyphenylmethyl siloxane, poly-higher alkyl siloxane and mixtures thereof 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 when applied from a pump spray or a roll-on applicator and a substantially reduced tendency to malfunction when applied from said pump spray or roll-on applicator.
Claim 2
Dependent Claim
95 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 polyorgano-siloxane selected from the group consisting of polyphenylmethyl siloxane, poly-higher alkyl siloxane and mixtures thereof 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 when applied from a pump spray or a roll-on applicator and a substantially reduced tendency to malfunction when applied from said pump spray or 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.
