  • Patent number: 11590254
    Abstract: An absorbent article comprising an absorbent gelling material (AGM) having an encapsulated compound of one or more odor controlling organic compounds disposed upon a surface thereof is described. Alternatively, an AGM particle comprising an encapsulated reactive compound of one or more odor controlling organic compounds disposed as a surface coating thereon is described. Additionally, a method to manufacture an absorbent article is described. The method provides for the steps of: a) providing a solution in a solvent system, the solution has an encapsulating agent and one or more odor controlling organic compounds as a surface coating; b) applying an amount of the solution to a surface of an AGM particle; and, c) incorporating the AGM particle having the solution applied thereto into the absorbent article.

  • Patent number: 10427133
    Abstract: Disclosed are absorbent articles having a cyclodextrin complex of one or more odor controlling organic compounds wherein the cyclodextrin is a substituted cyclodextrin (wherein the H atom of OH groups in positions 2, 3 and 6 is partially or entirely replaced by a substituent —R) having a substitution degree (DS) of 0.4 or more —R substituents per molecule of cyclodextrin and wherein substitution in position 2 is 20% or above, in position 6 is 20% or above and in position 3 is 50% or below. Cyclodextrin complexes of this type release the odor controlling organic compound much faster and in more complete manner than non-substituted or differently substituted cyclodextrin complexes thus the odor control efficacy is improved.
