Abstract

The present invention relates to soft surface coatings and absorbent articles comprising composite materials that are functionalized nanoparticles and in particular, metal-loaded nanoclays. In one embodiment, the metal is silver and the nanoparticle comprises a nanoclay. Silver ion is reduced to its neutral metal state (Ag 0 ) and loaded onto the nanoclay.

Claims (2)

1. A soft surface coating composition comprising: 1) a composite material comprising (a) an exfoliated nanoparticle having a surface and (b) a metal selected from Groups 3 to 12, aluminum and magnesium, wherein the metal is loaded onto the surface of the nanoparticle; 2) a carrier medium; 3) a surfactant; and 4) one or more adjunct ingredients, and wherein the metal is in the neutral (0) metal state.

2. An absorbent article comprising a composite material comprising (a) an exfoliated nanoparticle having a surface and (b) a metal selected from Groups 3 to 12, aluminum and magnesium, wherein the metal is loaded onto the surface of the nanoparticle and is in the neutral (0) metal state.
