摘要: Benzoyl peroxide intended for topical application is incorporated in novel formulations in which it is retained as impregnants inside the pores of porous solid particles or microspheres. The pores form a continuous network open to the exterior of the particles, permitting outward diffusion of the benzoyl peroxide impregnant at a controlled rate depending on the pore size. The impregnated particles are prepared by impregnation of preformed particles with the benzoyl peroxide.

摘要: Retinoic acid compositions intended for topical application are incorporated in novel formulations in which they are retained as impregnants inside the pores of porous solid particles or microspheres. The pores form a continuous network open to the exterior of the particles, permitting outward diffusion of the retinoic acid impregnant at a controlled rate depending on the pore size. The impregnated particles are prepared by impregnation of preformed particles with the retinoic acid.

摘要: Ionic compositions comprise an active ingredient absorbed within a network of internal pores defined by a plurality of polymeric particles. The particles are preferably crosslinked polymeric beads having a diameter in the range from about 5 to 100 microns and a surface charge density from about 0.1 to 10 meq/qm hydrogen ion capacity. The active ingredients are released from the ionic polymer beads over time when orally administered, applied to a keratinic material, typically human skin or hair or otherwise delivered to a target environment. The use of a cationic charge promotes adhesion of the beads to the keratinic material.
