Abstract: A medium for isolating or releasing an electrostatically charged component from or into an aqueous composition. The medium has a polyelectrolyte film on at least one surface of an article wherein the polyelectrolyte film is characterized by an interpenetrating network of a predominantly positively charged polymer and a predominantly negatively charged polymer. The predominantly positively charged polymer, the predominantly negatively charged polymer or both contain (i) a pH sensitive imidazole repeat unit having a pKa between 3 and 9, or (ii) a redox sensitive repeat unit selected from the group consisting of quaternized bipyridine repeat units, coordinated metal repeat units, pyrrole repeat units, aniline repeat units, thiophene repeat units and combinations thereof having a redox potential between +1.2 volts and ?1.2 volts versus a standard hydrogen electrode.

Abstract: The present invention is directed to enantioselective polyelectrolyte complex films. Further, said films may be free or isolated membranes, or coatings on substrates such a porous substrates, capillary tubes, chromatographic packing material, and monolithic stationary phases and used to separate chiral compounds. The present invention is also directed to a method for forming such enantioselective polyelectrolyte complex films.

Abstract: A conditioning composition is used in functional systems (personal care and household care compositions) that has a nonionic hydrophobically modified cellulose ether (HMCE) having a weight average molecular weight (Mw) with a lower limit of 400,000 and an upper limit of 2,000,000 and a hydrophobic substitution lower limit of 0.6 wt % and an upper limit amount which renders said cellulose ether insoluble in a 5 wt % solution of surfactant and less than 0.05% by weight soluble in water and wherein the cellulose ether provides conditioning benefit to the functional system substrate. This composition has at least one active functional system ingredient.
