  • Patent number: 6319507
    Abstract: Crushable gel beads 10 formed of an agar complex provide novel cosmetic, pharmaceutical, etc. delivery vehicles for topical delivery of biologically or cosmetically active agents. Preferred agar beads 10 are complexes of a continuous phase of agar gel 12 in a self-supporting solid or semi-solid form with a restraining polymer 14. Entrapped in and dispersed randomly throughout each agar bead 10 is a water-soluble, preferably polar, restraining polymer 14, preferably a quaternized cationic polymer, such as polyquaternium 24 or steardimonium hydroxyethylcellulose. Various active agents 16 may be bound to restraining polymer 14, for example ascorbic acid, lactic acid or papain. Methods of manufacture are also described.

  • Patent number: 6306378
    Abstract: This invention relates to a two-part system useful for treating proteinaceous substrates. The two-part system has a first part comprising a water-soluble/dispersible reactive polyimido compound and a second part comprising a nucleophilic catalytic agent. The polyimido compounds may be selected from the group consisting of polysuccinimide compounds, polyglutimide compounds, and copolymers of thereof. The polyimido compound may also comprise a functionalizing moiety that provides functionality to the polyimido compound and is preferably derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates; and a water-solubilizing/dispersing moiety that provides water-solubility and/or water-dispersibility to the polyimido compound and is preferably derived from a nucleophilic moiety selected from the group consisting of amines, alcohols, phenols, thiols, and carboxylates.
