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.
