This invention relates to water-soluble/dispersible reactive functionalized imido and polyimido compounds, wherein the polyimido compounds may be selected from the group consisting of polysuccinimide compounds, polyglutimide compounds, and copolymers of thereof. The polyimido compound comprises a functionalizing moiety F 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. The invention also pertains to a proteinaceous substrate to which the imido or polyimido compound has been covalently bonded and to a method for treating a proteinaceous substrate with the imido or polyimido compound.

Use of water-soluble/dispersible reactive functionalized derivatives of polyimido compounds for modifying proteinaceous substrates

This invention involves skin cleaning products and tapes for removing keratotic plugs, dirt and other debris found on the skin and in skin pores and comprising a poly(vinyl acetamide) polymer based adhesive composition applied to a substrate backing material.

Poly(vinyl acetamide) adhesive for skin cleaning tape

This invention involves skin cleaning products and tapes for removing keratotic plugs, dirt and other debris found on the skin and in skin pores and comprising a starch based remoistenable adhesive composition wherein the starch has from about 0 to 70% by weight amylose content and is converted to from about 30 WF to 20 DE.
