Abstract
Disclosed are antiperspirant stick compositions that exhibit substantially less visible residue (whitening) upon application to the skin or after drying and which exhibit improved aesthetics and superior cosmetic properties. The compositions include (a) non-volatile emollients that are not silicone materials and which have (individually or as a mixture) a refractive index of at least 1.4460, and which have adsorption and desorption properties relative to the antiperspirant material sufficient to achieve the desired reduction in residue (whiteness); (b) a vehicle (for example, cyclomethicone), (c) a gelling agent (for example, stearyl alcohol and hydrogenated castor oil); (d) at least one active antiperspirant material (for example, particulate antiperspirant metal salts); and (e) a surfactant.
