HIGH OIL CLEAR EMULSION WITH ELASTOMER.

摘要

A clear antiperspirant and/or deodorant composition is disclosed 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 dimethicone/vinyldimethicone crosspolymer composition made by reacting a polymethylhydrogensiloxane with an alpha, omega-divinylpolydimethyl siloxane for which the dimethicone/vinyl-dimethicone crosspolymer composition is used at a concentration of 4-10% in cyclomethicone, has a refractive index in the range of 1.392-1.402 at 25 degrees C and a viscosity in the range of 0.013-1x104 Pascal seconds; (ii) 0.1-5% of a silicone copolyol having an HLB value <=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 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.
