Abstract
Described are fabric care pellets comprising an amphiphilic polymer, preferably an ethylene acrylic acid copolymer, a surfactant, and a filler, wherein the pellet contains 30 wt % to 90 wt % amphiphilic polymer, preferably ethylene acrylic acid copolymer, and methods of making and using the same.
Claims22
A fabric care pellet, comprising:
- an amphiphilic polymer selected from the group consisting of ethylene acrylic acid copolymer, MAH-grafted ethylene polymer, ethylene methacrylic acid copolymer, vinyl acetate-acrylic acid copolymer, polylactic acid, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, polyethylene vinyl acetate, polyvinyl acetate, ethylene-methyl methacrylate copolymer, ethylene-butyl acrylate copolymer, and blends thereof, including their salts;
- a surfactant;
- and
- a filler, wherein the pellet contains 30% to 90% by weight of the amphiphilic polymer, based upon the weight of the pellet.
A method of cleaning fabric, comprising contacting the fabric with a fabric care pellet comprising an amphiphilic polymer selected from the group consisting of ethylene acrylic acid copolymer, MAH-grafted ethylene polymer, ethylene methacrylic acid copolymer, vinyl acetate-acrylic acid copolymer, polylactic acid, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, polyethylene vinyl acetate, polyvinyl acetate, ethylene-methyl methacrylate copolymer, ethylene-butyl acrylate copolymer, and blends thereof, including their salts;
- and a filler, wherein the pellet contains 30% to 90% by weight of the amphiphilic polymer, based upon the weight of the pellet.
20-21. (canceled)
A method of making a fabric care pellet, comprising hot melt extruding a composition of an amphiphilic polymer selected from the group consisting of ethylene acrylic acid copolymer, MAH-grafted ethylene polymer, ethylene methacrylic acid copolymer, vinyl acetate-acrylic acid copolymer, polylactic acid, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, polyethylene vinyl acetate, polyvinyl acetate, ethylene-methyl methacrylate copolymer, ethylene-butyl acrylate copolymer, and blends thereof, including their salts;
- a surfactant;
- and a filler, wherein the pellet contains 30% to 90% by weight of the amphiphilic polymer, based upon the weight of the pellet.
