    • 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").
    • 本发明包括一种液体组合物,当与某些类型的施用器特别是具有多孔表面的施用器一起使用时,其提供干燥的感觉和减少的泄漏,该组合物通过组合活性相和硅氧烷相制成。 活性相通过组合:(a)10-70%的选择的二醇; (b)0.1-10%HLB大于8的非离子乳化剂; (c)0.01-30%的化妆品活性成分; 和(d)0-20%的乙醇和/或异丙醇。 硅氧烷相通过以下方法制备:(a)0.1-10%选择的乳化剂; (b)0-30%的非挥发性硅酮; (c)0-30%的挥发性硅酮; 和(d)0-25%的有机润肤剂; 条件是:(a)硅氧烷相含有至少10%的硅氧烷; (b)硅酮相与活性相的比例在1:1至1:4的范围内; 和(c)处理该组合物以将粘度保持在2,000-200,000厘泊(“cps”)的范围内。
