| abstract |
Compositions comprising activatable aggregates are described herein. The aggregate has a core and a shell. In some embodiments, when the aggregate is exposed to acoustic energy, the core of the aggregate comprises a hydrogel capable of absorbing a relatively large amount of water. The core of the aggregate is covalently bound to the shell of the linear aliphatic moiety. The aggregates are synthesized to minimize the amount of water in the core prior to exposure to acoustic energy. A method of moisturizing using the composition is also provided. |
