The invention provides better stability to formulation in addition to improved delivery of hydrophilic actives from the formulation.

BACKGROUND OF THE^' INVENTION

[00021 Aiiionicaliy modified silicones are commonly used in personal, care compositions to provide smoothness and feelings of softness. For example, carboxylated silicones have been reported to exhibit humectant-like characteristics to reduce the transepidermal water loss of skin. Furthermore, U.S. Patent No, 5,993,832 discloses a cosmetic emulsions comprising of amonieally modified silicone and acidic cosmeceutical actives to have better stability, sensorial and controlled release characteristics over traditional silicone surfactants.

[0003] However, these carboxylated silicones cannot provide high level of matrix building and therefore require other additives that may result into slower active compound diffusion from a high consistency formula.
