Patent ID: 6942869

Claim:
A keratotic plug remover consisting essentially of: (i) a polymer (A) having sulfonic or sulfate groups or having salts thereof, selected from the group consisting of (a) homopolymers of a vinyl having a (meth)acryloyl skeleton or styrene skeleton and a sulfonic, group, or a salt thereof, (b) copolymers of a vinyl having a (meth)acryloyl skeleton or styrene and a sulfonic, group, salt thereof with a monomer copolymerizable therewith, (c) polysaccharides having a sulfonic group or a salt thereof, and (d) homopolymers of vinylsulfonic acid, allylsulfonic acid or a salt thereof, or copolymers of such a monomer with a monomer copolymerizable therewith wherein said polymer (A) is not poly 2-acrylamide-2-methylpropane sulfonate (AMPS); and (ii) a nonionic polymer (B) selected from the group consisting of (e) homopolymers of a vinyl monomer having an amide group, (f) copolymers of a vinyl monomer having an amide group with a monomer copolymerizable therewith; and (g) polyethylene glycol, polypropylene glycol, polyglycerol, polyvinyl alcohol, pullulan, guar gum and hydroxyethyl cellulose, wherein polymer (A) and nonionic polymer (B) are soluble in water, and a mixing proportion of said polymer (A) to nonionic polymer (B) is 30:70 to 70:30 in terms of a weight ratio of (A) to (B).
