Superabsorbent polymer containing triclosan as odor-controlling compound

摘要

Odor-controlling superabsorbent polymer having an odor-controlling compound homogeneously distributed throughout an SAP article. Manufacturing an odor-controlling superabsorbent polymer comprises: (a) forming a mixture comprising water, a vinyl monomer, and an odor-controlling compound selected from cyclodextrin compound, an amphoteric surfactant and/or a water-insoluble-phosphate; (b) polymerizing the mixture to form a hydrogel; (c) optionally, admixing the polymeric hydrogel formed in step (b), with a second odor-controlling compound selected from cyclodextrin compound, triclosan, an amphoteric surfactant and/or a water-insoluble phosphate; and (d) optionally, neutralizing the unneutralized hydrogel. Independent claims are also included for: (1) an odor-controlling superabsorbent polymer particle; (2) articles e.g. nappies and catamenial devices comprising the superabsorbent polymer in (1); (3) manufacturing a superabsorbent polymer comprising: (i) forming a mixture comprising water and a vinyl monomer; (ii) polymerizing the mixture to form a hydrogel; (iii) admixing the hydrogel formed in step (ii) with a odor-controlling compound selected from cyclodextrin compound, triclosan and/or amphoteric surfactant; and (iv) optionally neutralizing the hydrogel admixture formed in (iii); and (4) an odor-controlling superabsorbent polymer prepared by the method in (3); (5) an odor-controlling superabsorbent polymer prepared by the claimed method.
