  • Patent number: 5833964
    Abstract: Disclosed are antiperspirant stick compositions that exhibit substantially no visible residue (whitening) upon application to the skin or after drying. The compositions include both emollients that are silicone materials and emollients that are not silicone materials, these materials having a refractive index of at least 1.4460, in addition to including a vehicle (for example, cyclomethicone), a gelling agent (for example, stearyl alcohol and hydrogenated castor oil) and the active antiperspirant material (for example, particulate antiperspirant metal salts). These compositions reduce the necessity of using expensive silicone materials, while still achieving antiperspirant compositions with substantially no visible residue.
