  • Durable hydrophilic coating compositions
    Patent number: 9314544
    Abstract: A durable hydrophilic coating composition is provided comprising a film forming polymer, a wetting agent and from about 0.001% to about 40%, by weight of the composition, of nanoparticles. The nanoparticles are selected from the group consisting of alumina, silica and combinations thereof and have a particle size of from about 1 to about 750 nanometers. The weight ratio of the film forming polymer to the nanoparticles is from about 1:1 to about 1:30. A disposable absorbent article is also disclosed.

  • Nonwoven Having Durable Hydrophilic Coating
    Publication number: 20110268932
    Abstract: A nonwoven material coated with an amine-polyether silicone. The coating composition may include a wetting agent, an acid, and/or a defoamer. The nonwoven may be incorporated into a disposable absorbent article. The disposable absorbent article may include at least trace amounts of a mineral oil. The coating of the nonwoven may be durable even in the presence of mineral oil.
