Summary: | Cationic 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/gm hydrogen ion capacity. The active ingredients are released from the cationic polymer beads over time when applied to a keratinic material, typically human skin or hair. The cationic charge promotes adhesion of the beads to the keratinic material. |
