     FIELD OF THE INVENTION 
     This invention relates generally to aerosols and to methods and devices for delivering aerosols to the skin and/or hair of a person, including to antiperspirant compositions and other personal care compositions for delivery via aerosols of the powder suspension type suitable for spraying from a pressurized container. 
     BACKGROUND 
     Antiperspirant compositions normally contain an antiperspirant active compound which chemically suppresses the production of perspiration by sweat glands. One example of such a compound is aluminum chlorohydrate, which acts as an astringent to inhibit perspiration of the user. Such antiperspirant formulations can be applied to the skin using several different modes of application, including roll-on and stick forms. However, those skilled in the art will appreciate that applying an antiperspirant formulation in the form of an aerosol spray can have several advantages when applied on the skin. 
     For aerosol antiperspirant sprays, the antiperspirant active compound is usually suspended as an insoluble powder in a liquid carrier together with a non-aqueous liquefied volatile propellant in a pressurized aerosol container. The aerosol spray is produced by rapid transition of the propellant from the liquid to the vapor phase as it dispenses from the atomizing valve of the aerosol container. As a result, application of antiperspirant using an aerosol spray has gained wide acceptance for a number of reasons. Aerosol application of an antiperspirant active compound in the form of a dry powder suspended in the propellant is cosmetically desirable because the antiperspirant can be smoothly and effectively applied to the skin in a manner that feels dry and comfortable. Furthermore, because the antiperspirant powder does not dissolve in the liquefied propellant medium, the antiperspirant salt does not corrode ordinary metal aerosol cans. 
     One difficulty associated with antiperspirant aerosol sprays is that the delivery of small particles of antiperspirant active compound can pose some technical difficulties. For example, a finely divided spray can create difficulties in ensuring that a large proportion of the active components travel to, remain on and are absorbed by the skin of the user. This problem arises because the dry powder spray in many cases tends to form a wide dispersion or cloud, resulting in many of the active particles not hitting the target area. Also, even when the particles hit the target area, the relatively high energy imparted to the particles by the propellant can cause many particles to bounce off the skin of the user. In order to address these problems, it has been common practice to utilize an anhydrous liquid carrier component to disperse and/or suspend the active powder, and then fine droplets of the anhydrous carrier are able to travel to the target area in a more well-formed spray pattern, and the problem of dry particles bouncing off the user is greatly reduced. Certain silicone liquids have been heretofor developed for use as carrier fluids for the active ingredients in several personal care compositions, including in antiperspirant aerosol sprays. However, a need has developed to reduce or eliminate the use of the frequently used volatile silicone fluids “D-4,” which is octamethylcyclo-tetrasiloxane [(CH3)2SiO]4 and “D-5,” which is decamethylcyclopentasiloxane [(CH3)2SiO]5, in products which result in those liquids escaping into the biosphere. For example, see the publication by the Danish Ministry of the Environment has published a paper entitled “Siloxanes (D3, D4, D5, D6, HMDS) Evaluation of health hazards and proposal of a health-based quality criterion for ambient air Environmental Project No. 1531, 2014), which is incorporated herein by reference. Developing a substitute carrier liquid for the silicone liquids used for the active ingredients in personal care products, including antiperspirant aerosol spray products, represents significant technical challenges. For example, the substitute fluid must be able to effectively disperse and/or suspend the active compounds without deteriorating the effectiveness of the particles for the intended purpose, such as to prevent perspiration. In addition, the carrier fluid must satisfy a difficult-to-achieve combination of features, including the ability to remain as a fine, well-targeted spray as it travels to the skin of the user and at the same time contact the shin without imparting either an overly wet/oily feel or an overly dry feel. It is a difficult technical challenge to develop a new carrier fluid that is able to at once achieve this combination of features at the same level as has been achieved by the previously used silicone liquids.

     The formulation was prepared by first adding the indicated amounts of components 1, 2 and 4 into a beaker and then mixing those components until uniform using a rotor stator mixer. The mixture builds viscosity as mixing continued. Then component 5 was added as mixing was continued and viscosity slowly continues to increase as mixing continues for an additional five (5) minutes. The mixture of components 1, 2, 4 and 5 from the beaker was then added into a sealable container with trans-1233zd that had been chilled to a temperature below 19° C. 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. 
     The formulation is tested by spraying onto the skin of a user. While the formulation has generally acceptable spray characteristics similar to representative commercially available antiperspirant aerosol products based on D-5 as described in Comparative Example C1, it has a feel that is much dryer on the skin than commercially available D-5 antiperspirant aerosol products based on the results from Example C1. 
     Example 1

     The formulation was 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 was added as mixing was 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 was then added into a sealable container with component 3A (trans-1233zd) that had been chilled to a temperature below 19° C. 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. 
     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. 
     Example 3 
     A formulation the same as shown in Table C1 was prepared except a 75:25 weight ratio mixture of trans-1233zd and safflower oil is used in place of D-5 on an equal weight basis as indicated in Table 3 below:

     The formulation was prepared by first adding the indicated amounts of components 1, 2, 3 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 was added as mixing was continued and viscosity slowly continued to increase as mixing continued for an additional five (5) minutes. The mixture of components 1, 2, 3, 4 and 5 from the beaker was then added into a sealable container. 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. 
     The formulation is tested by spraying onto the skin of a user. The formulation has spray characteristics substantially inferior to the representative commercially available antiperspirant aerosol products based on D-5 as described in Comparative Example C1, that is, the spray was found to be wet and to have a high level of liquidity.

     A formulation the same as shown in Table C1 was prepared except diheptyl succinate based carrier sold under the trade designation Lex-Feel N-20 is used in place of D-5 on an equal weight basis as indicated in Table C4 below:

     The formulation was 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 was added as mixing was 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 was then added into a sealable container with component 3A (trans-1233zd) that had been chilled to a temperature below 19° C. 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. 
     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. 
     Comparative Example 5—D-5 Replaced by diheptylsuccinate in Lex-Feel N-7 
     A formulation the same as shown in Table C1 was prepared except diheptyl succinate based carrier sold under the trade designation Lex-Feel N-7 (with a lower viscosity than N-20) is used in place of D-5 on an equal weight basis as indicated in Table C5 below:

     The formulation is tested by spraying onto the skin of a user. The formulation has spray characteristics similar to the representative commercially available antiperspirant aerosol products based on D-5 as described in Comparative Example C1. However, in terms of feel on the skin the formulation was substantially inferior to the representative commercially available antiperspirant aerosol products based on D-5 as described in Comparative Example C1, that is, the formulation felt very oily.

     The formulation was 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 was added as mixing was 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 was then added into a sealable container with component 3A (trans-1233zd) that had been chilled to a temperature below 19° C. 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. 
     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. 
     Example 5 
     A formulation the same as shown in Table C1 was prepared except a 75:25 weight ratio mixture of trans-1233zd and safflower oil is used in place of D-5 on an equal weight basis as indicated in Table 3 below:

     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. 
     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.
