Abstract:
1. An oil-in-water nanogel composition comprising an oil phase having a mean droplet size of less than about 100 nm, an emulsifier, a water phase, and a silicone oil component comprising at least one volatile silicone oil different than the oil phase, wherein said oil phase and said silicone component are self-structured in the absence of a thickening agent by a high shear/pressure treatment, at least about 20 percent by weight of the composition and at least about 5 times the amount of the emulsifier and the nanogel has a difference in complex viscosity of at least about 10,000 poise under oscillation stress in the range of about 0 to 5,000 (dyne/cm 2 ).
