摘要 |
The present invention provides a hybrid material comprised of an active component for raw materials for cosmetics and a layered metal hydroxide, showing good stability, low toxicity, low irritation, good sustained release and good dispersibility. The present invention provides a method for preparing the hybrid material, using the coprecipitation method, the ion-exchange method or the adsorption method, depending on properties of the active component for raw materials for cosmetics. The method may further comprise a step of coating the surface of the hybrid material after preparation of the hybrid material.
