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 a selected mixture of silicone liquids or selected silicone liquids with silicone polyether copolymers.
Claims15
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 mixture of a volatile cyclic polydimethyl siloxane of the structural formula ##STR2## and a non-volatile silicone selected from the group consisting of polyalkyl siloxane, polyalkylaryl siloxane, polyether siloxane copolymer and mixtures thereof, to substantially reduce the tackiness of said complex during drying;
- and a sufficent amount of alcohol to result in said solution;
- said composition being characterized by having substantially reduced tackiness and giving a perception of quick drying 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.
A method for substantially reducing the tackiness during drying giving the perception of being quick drying and substantially reducing the tendency to cause pump or roll-on malfunction of an alcohol solution containing an alcohol soluble aluminum chlorhydroxide complex comprising introducing into said solution a sufficient amount of a mixture of volatile cyclic polydimethyl siloxane of the structural formula ##STR5## and a non-volatile silicone selected from the group consisting of polyalkyl siloxane, polyalkylaryl siloxane, polyether siloxane copolymer and mixtures thereof, to result in said substantial reduction of tackiness, said perception of quick drying and said tendency to malfunction.
