ACOUSTICALLY-ACTIVATED COSMETIC HYDROGELS |
摘要 |
A composition that includes an activatable aggregate is 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 includes a hydrogel that is capable of absorbing a relatively large amount of water. The core of the aggregate is covalently bound to a shell of linear aliphatic moieties. The aggregate is synthesized to minimize the amount of water in the core, prior to exposure to acoustic energy. Methods of hydrating using the compositions are also provided. |
