Claim:
1. An aqueous liquid composition for removing a keratotic plug comprising from more than 10% to about 20% by weight polyvinyl alcohol (PVA), wherein said PVA comprises a low viscosity PVA having a viscosity from about 1.0 to 20 cps and a high viscosity PVA having a viscosity higher than the viscosity of said low viscosity PVA, said high viscosity PVA having a viscosity from about 20 to about 100 cps said viscosities as determined in a 4% aqueous solution at 20° C.; wherein said PVA is derived from hydrolysis of polyvinyl acetate and has a degree of hydrolysis from about 85% to about 95%; from about 5% to about 15% by weight polyvinylpyrrolidone (PVP), said composition being substantially free of salt-forming groups, and having a viscosity from about 25,000 cps to about 200,000 cps.
