Claims
- 1. An aqueous water-nonabsorptive contact lens cleaning and storage solution consisting essentially of (1) an anionic surface active agent, (2) a non-ionic surface active agent, and (3) a compound selected from the group consisting of polysaccharides and derivatives thereof, the ratio of the component (1) to the component (2) being from about 32:68 to about 94:6 by weight, the total concentration of the components (1) and (2) being from about 0.05 to about 4.5% by weight, the concentration of the component (3) being from 0.01 to 10% by weight, and said solution having a pH of 4.8 to 8.5,
- wherein the anionic surface active agent is selected from the group consisting of a sodium alkylbenzene sulfonate, a sodium alpha-olefin sulfonate, a sodium polyoxyethylene alkylether sulfates, a sodium alkyloylmethyltaurinate, a sodium alkyloylsarcosinate, a sodium polyoxyethylene alkylether phosphate, a sodium di(polyexythylene alkylether)phosphate, and a sodium polyoxyethylene alkylphenylether sulfate; and
- wherein the non-ionic surface active agent is selected from the group consisting of a polyoxyethylene higher fatty acid ester, a higher fatty acid ester with a polyoxyalkylene-polyoxyethylene copolymer; a higher fatty acid ester with a polyhydric alcohol; a higher fatty acid ester with a polyoxyethylene polyhydric alcohol including polyoxyethylene glyceryl fatty acid esters and polyoxyethylene sorbitan fatty acid esters; a polyglycerin fatty acid ester; a polyoxyethylene alkyl ether; a polyglycerin ether with an alcohol; a polyoxyethylene fatty acid amide; a polyoxyethylene alkylamine; a polyoxyethylene alkylphenyl ether; a condensate of polyoxyethylene alkylphenol ether with formaldehyde; a polyoxyethylenepolyoxypropylene block copolymer; a phosphate, a polyethyleneglycol adduct of one of a hydrogenated castor oil, castor oil and sterol; and a polyoxyethylene sorbian fatty acid ester.
- 2. The solution of claim 1, wherein said anionic surface active agent is a member selected from the group consisting of a sodium alkylbenzene sulfonate, a sodium .alpha.-olefin sulfonate, a sodium polyoxyethylene alkylether sulfate and a sodium polyoxyethylene alkylphenylether sulfate.
- 3. The solution of claim 1, wherein said non-ionic surface active agent is a member selected from the group consisting of a polyglycerin fatty acid ester, a polyoxyethylene fatty acid ester, a polyoxyethylene alkyl ether and a polyoxyethylene alkylphenyl ether.
- 4. An aqueous water-nonabsorptive contact lens cleaning and storage solution consisting essentially of (1) an anionic surface active agent, (2) a non-ionic surface active agent, and (3) a compound selected from the group consisting of polysaccharides and derivatives thereof, the ratio of the component (1) to the component (2) being from about 32:68 to about 94:6 by weight, the total concentration of the components (1) and (2) being from about 0.05 to about 4.5% by weight, the concentration of the component (3) being from about 0.1 to 10% by weight, and said solution having a pH of 4.8 to 8.5,
- wherein said anionic surface active agent is a member selected from the group consisting of sodium alkylbenzene sulfonate, a sodium .alpha.-olefin sulfonate, a sodium polyoxyethylene alkylether sulfate and a sodium polyoxyethylene alkylphenylether sulfate, and said non-ionic surface active agent is a member selected from the group consisting from the group consisting of a polyglycerin fatty acid ester, a polyoxyethylene fatty acid ester, a polyoxyethylene alkyl ether and a polyoxyethylene alkylphenyl ether.
