  • Publication number: 20210259895
    Abstract: A liquid permeable substrate for an absorbent article is disclosed. The substrate includes a first layer including a hydrophobic material and a second layer including a hydrophilic material. The first layer is joined to the second layer. The substrate includes a plurality of recesses, a plurality of projections, and a plurality of land areas. The land areas surround at least a majority of the plurality of projections and a plurality of the recesses. The plurality of recesses, the plurality of projections, and the plurality of land areas together form a first three-dimensional surface on a first side of the substrate and a second three-dimensional surface on a second side of the substrate. The substrate has an overall z-directional height in the range of about 1000 ?m to about 6000 ?m according to the Overall Substrate Height Test.

  • 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.
