The vessel was then sealed and mixing continued until the contents were uniform, and then the mixture is allowed to equilibrate for about 30-60 minutes. The liquid concentrate mixture thus produced is added into a sealable aluminum spray can, the can is sealed and then the propellant (component 6) is charged into the can.

[0249] The formulation is prepared by first adding the indicated amounts of components 1, 2, 3B and 4 into a beaker and then mixing those components until uniform using a rotor stator mixer. The mixture built viscosity as mixing continued. Then component 5 is added as mixing is continued and viscosity slowly continued to increase as mixing continued for an additional five (5) minutes. The mixture of components 1, 2, 3B, 4 and 5 from the beaker is then added into a sealable container with component 3A (trans-1233zd) that had been chilled to a temperature below 19° C. The vessel is then sealed and mixing continued until the contents are uniform, and then the mixture is allowed to equilibrate for about 30-60 minutes. The liquid concentrate mixture thus produced is added into a sealable aluminum spray can, the can is sealed and then the propellant (component 6) is charged into the can.

[0250] The formulation is tested by spraying onto the skin of a user. The formulation has acceptable spray characteristics similar to representative commercially available antiperspirant aerosol products based on D-5 as described in Comparative Example C1 and it has a feel on the skin that is as good as or better than the commercially available D-5 antiperspirant aerosol products based on comparison to the results from Example C1.
