Cosmetic and Pharmaceutical Masks Based on Ion-Pair Delivery System
First Claim
1. A cosmetic or pharmaceutical mask composition suitable for facial, hair, skin, or body application comprising:
- (i) At least one biopolymer, polymer, or polyvalent metal complexing composition as one component of the ion-pair, which forms the matrix of mask composition (Part I), from about 0.1% to about 50%, and (ii) At least one divalent or trivalent metal cation as the other component of the ion-pair (Part II), which causes the cross-linking of the first component of the ion-pair composition (Part I), from about 0.1% to about 50%, and (iii) At least one skin, hair, or body beneficial cosmetic or pharmaceutical composition, from about 0.0001% to about 25%, and (iv) A cosmetically or pharmaceutically acceptable delivery system or a carrier base composition.

Abstract
The present invention discloses a novel ion-pair delivery system based mask compositions for face, hair, skin, and body applications. These compositions come off from the site of their application essentially in one piece with the appearance, for example, of a piece of sea-weed or a continuous film. These mask compositions are suitable for a variety of delivery system methods, such as peel-off mask, moisturizing mask, exfoliating mask, prosthetic mask, soaking mask, depilatory mask, rub-off mask, two-phase mask, two-compartment mask, heat-releasing mask, and such. These mask compositions are made from the biopolymer based films that are cross-linked with divalent or trivalent metal cations. During the cross-linking process, such divalent and trivalent metal cations may also act as release agents for other face, hair, skin, and body beneficial compositions in their enhanced bioavailable forms by an ion-pair activation mechanism.
