  • Publication number: 20020120241
    Abstract: The present invention relates to compositions and absorbent articles including compositions for protecting the skin barrier. The compositions can be applied to the bodyfacing surfaces of absorbent articles so that the compositions come into contact with the skin. The compositions of the invention have improved stability on the bodyfacing surfaces after processing. The compositions of the invention provide several benefits including prevention and alleviation of skin irritations associated with the use of absorbent articles. The compositions can include hydrophilic solvents, high molecular weight polyethylene glycols, fatty alcohols, fatty acids and decoupling polymers.

  • Publication number: 20020058056
    Abstract: The present invention relates to a composite material including a substrate with a first and a second surface, a boundary layer which is comprised of one or more compositions, and a topical application. The boundary layer is applied on the first surface of the substrate, and the topical application is applied to a surface of the boundary layer opposite of the substrate. Transfer efficiency of the topical application is enhanced as the transfer forces necessary to separate the topical application from the boundary layer are lower than the transfer forces necessary to separate the substrate from the boundary layer.
