    Abstract: The invention comprises a liquid composition which provides a drier feel and reduced leakage when used with certain types of applicators, especially an applicator having a porous surface, which composition is made by combining an active phase and a silicone phase. The active phase is made by combining: (a) 10-70% of a selected glycol; (b) 0.1-10% of a nonionic emulsifier having an HLB greater than 8; (c) 0.01-30% of a cosmetically active ingredient; and (d) 0-20% of ethanol and/or isopropanol. The silicone phase is made by combining: (a) from 0.1-10% of a selected emulsifier; (b) 0-30% of a non-volatile silicone; (c) 0-30% of a volatile silicone; and (d) 0-25% of an organic emollient; provided that: (a) the silicone phase contains at least 10% silicone; (b) the ratio of silicone phase to active phase is in the range of 1:1 to 1:4; and (c) the composition is processed to maintain a viscosity in the range of 2,000-200,000 centipoise ("cps").
