The present invention relates to a controlled release system useful to stabilize retinol, retinol derivatives, and extracts containing retinol in cosmetic, dermatological, and pharmaceutical compositions. More specifically, the present invention pertains to stabilized retinol in a solid hydrophobic particle that sustains the release of retinol during the product shelf life and enables a gradual and prolonged release of effective levels of retinol and other cosmetic, dermatological, and pharmaceutical active ingredients into biological surfaces. The present invention also refers to a process of stabilizing retinol, retinol derivatives, and extracts containing retinol in cosmetic, dermatological, and pharmaceutical compositions. The invention further relates to cosmetic, dermatological, and pharmaceutical products comprising stable retinol in a hydrophobic particle that can deliver effective levels of retinol and other cosmetic, dermatological, and pharmaceutical active ingredients to biological surfaces over an extended period of time.
本发明涉及一种控释系统,用于稳定化妆品、皮肤病学和药物组合物中的视黄醇、视黄醇衍生物和含有视黄醇的提取物。更具体地说,本发明涉及在固体疏水性颗粒中稳定视黄醇,该颗粒可在产品保质期内维持视黄醇的释放,并使有效水平的视黄醇和其他化妆品、皮肤病学和药物活性成分逐渐并长时间地释放到生物表面。本发明还涉及一种稳定化妆品、皮肤病学和药物组合物中的视黄醇、视黄醇衍生物和含有视黄醇的提取物的工艺。本发明还涉及在疏水性颗粒中含有稳定视黄醇的化妆品、皮肤病学和药物产品,该疏水性颗粒可在较长时间内将有效水平的视黄醇和其他化妆品、皮肤病学和药物活性成分输送到生物表面。
