ABSTRACT:
Disclosed is a non-flowable anhydrous topical antiperspirant composition comprising a first portion and a second portion contiguous with the first portion. The first portion is semi-opaque to opaque and comprises a first hydrophobic carrier vehicle and a first gellant and has a particulate antiperspirant active suspended therein. The second portion is translucent to transparent and comprises a second hydrophobic carrier vehicle and a second gellant. Preferably, the second hydrophobic carrier vehicle has an average refractive index that approximately matches the refractive index of the second gellant. Ideally, for greater translucency the second portion will be substantially free of antiperspirant salt and/or other opacifying materials. Preferably, the first hydrophobic carrier vehicle also has an average refractive index that approximately matches the refractive index of the first gellant. Even more preferably, the second hydrophobic carrier vehicle and second gellant are comprised of substantially the same materials in substantially the same proportions as the first hydrophobic carrier vehicle and first gellant.
