  • Patent number: 5726143
    Abstract: The present invention relates to an article for improving anti-static protection of clothing dried in a clothes dryer. The article includes a substrate, a layer comprising a first quaternary ammonium anti-static agent that has a first melting point. The layer comprising the first quaternary ammonium anti-static agent is adhered to the substrate. The article also includes a layer comprising a second quaternary ammonium anti-static agent that is adhered to the first quaternary ammonium anti-static agent. The layer comprising the second quaternary ammonium anti-static agent has a melting point lower than the first melting point. The present invention also includes a method for making the article.

  • Patent number: 4891228
    Abstract: Disclosed are medicated cleansing pads comprising: (a) from about 50% to about 75% of a nonwoven fabric material; (b) from about 20% to about 75% (on a dry solids basis) of a water soluble polymeric resin of the formula:(A.sub.x).sbsb.m (B.sub.y).sbsb.nwherein A is one or more monomers selected from styrene or styrene derivatives and B is one or more monomers selected from butadiene or butadiene derivatives, x is the number of different A monomer components present in the copolymer chain, with x being an integer of 1 or more and y is the number of B monomer components present in the copolymer chain, with y being an integer of 0 or more and m:n is the weight ratio of A monomer components to B monomer components, and is from about 10:1 to about 1:5, preferably from about 5:1 to about 1:2, and (c) from about 0.1% to about 50% of salicylic acid active composition.
