Fine and stable silicone-in-water emulsions, well suited for cosmetic applications, e.g., for the treatment of hair (shampoo, rinse, etc.) or skin (skin care, dermatology, etc.), include (a) a VHV polydiorganosiloxane having a viscosity of at least 9x104 mPa.s at 25 DEG C., (b) at least one fluid silicone having a viscosity no greater than 50,000 mPa.s. at 25 DEG C. and (c) a sugar glyceride nonionic surface-active agent, and wherein the percentage by weight of such VHV polydiorganosiloxane (a) in the total silicone content (a)+(b) ranges from 5% to 50% and the ratio parts by weight of surface-active agent (c)/parts by weight of water is no greater than 0.7.
