MICROPARTICLES WITH CYCLODEXTRINS HAVING A DUAL LEVEL OF ENCAPSULATION |
| 摘要 |
Microparticles include a solid and porous matrix which includes at least one biocompatible polymer. The matrix includes, within its pores, water and at least one inclusion complex formed between a cyclodextrin and at least one first active ingredient. The microparticle is characterized in that the first active ingredient is selected in the group constituted by cosmetic active ingredients and dermatological active ingredients for topical use and in that the microparticle further includes at least one second cosmetic or dermatological active ingredient for topical use which is not in the form of an inclusion complex with the cyclodextrin. |

1. A microparticle which includes a solid and porous matrix, said matrix comprising at least one biocompatible polymer and including, within its pores, water and at least one inclusion complex formed between a cyclodextrin and at least one first active ingredient, wherein the first active ingredient is selected in the group constituted by cosmetic active ingredients and dermatological active ingredients for topical use and said microparticle further comprises at least one second cosmetic or dermatological active ingredient for topical use which is not in the form of an inclusion complex with the cyclodextrin. |
