Abstract:
A clear antiperspirant and/or deodorant composition in the form of an emulsion having a refractive index less than 1.42 and comprising:(a) 25-70% of an external phase comprising: (i) 0.1-10%, on an actives basis, of at least one elastomer which is a cyclomethicone (and) dimethicone crosspolymer made with an â‰¡Siâ€”H containing polysiloxane and an alpha, omega-diene of formula CH2&boxH;CH(CH2)xCH&boxH;CH2, where x=1-20, to form a gel by crosslinking and addition of â‰¡Siâ€”H across double bonds in the alpha, omega diene, which crosspolymer has a viscosity in the range of 50,000-3,000,000 centipoise; (ii) 0.1-5% of a silicone copolyol having an HLB value &lE;8; (iii) 0.1-68% of a volatile silicone selected in an amount to complete the external phase; (iv) 0-10% of a cosurfactant or emulsifier having an HLB value in the range of 1-15; (v) 0-5% of a non-volatile silicone; and (b) 30-75% of an internal phase which is made with: (i) 7-25% (on an anhydrous actives basis (excluding the waters of hydration) of an antiperspirant active; (ii) 0-10% ethanol; (iii) additional water as required to adjust the refractive index; (iv) 0-5% of an antimicrobial agent; and (v) 0-5% of an ionizable salt; wherein (1) the conductance of a water droplet applied to the surface of a thin film of the antiperspirant and/or deodorant composition is at least 250 micro Siemens/cm/ml as measured by a fixed geometry test at a loading of at least 7% by weight level of antiperspirant active; and (2) all amounts are in percent by weight based on the total weight of the composition.
