  • Publication number: 20180228145
    Abstract: The present disclosure is directed towards an absorbent binder composition that includes a hydrophilic polymer which has the capability of post-application, moisture-induced cross-linking. The absorbent binder composition can include 1) a superabsorbent polymer material which can include at least 15 mass percent monoethylenically unsaturated polymer, such as carboxylic acid, sulphonic acid, or phosphoric acid, or salts thereof, and an acrylate or methacrylate ester that contains an alkoxysilane functionality and 2) a polyvalent metal cation having a valence of at least two. Upon loss of water by evaporation, the alkoxysilane functionality forms a silanol functional group which condenses to form a crosslinked polymer. Upon exposure of the absorbent binder composition to a biological material, such as urine, blood, or feces, the biological material can interact with the polyvalent metal cation and can serve as a catalyst to accelerate the polymer cross-linking and gelation of the polymer.

  • Patent number: 8552251
    Abstract: A laminate having health-benefit agents therein is made by particle stabilization within the lamination process. By changing the substrate type (tissue, nonwoven, film) and/or the physical composition and/or attributes of the laminate layers, the release of the health-benefit agents can be controlled. The laminate, sometimes referred to as a liner, may be used in personal absorbent articles such as diapers, feminine pads, bandages, bed pads, and the like.
