PH-controlled protein removing cleaner |
摘要 |
<p>A pH controlled protein removal system and a method of using it in the substantial absence of a protein digesting enzyme and, preferably, in the substantial absence of a surfactant is disclosed. The system is a pH-controlled protein-cleaning composition for e.g. contact lenses comprising (a) water; (b) a tonicity builder sufficient to render said composition ophthalmically acceptable; and (c) a pH regulator sufficient to provide and maintain the pH of the composition at a pH of about 7.5 to about 11.5; in the substantial absence of a protein-digesting enzyme. The inventive method is for removing proteinaceous deposits from a polymeric substrate, e.g. a contact lens, in the substantial absence of a proteinaceous deposit digesting enzyme, comprising contacting said polymeric substrate having a proteinaceous deposit thereon with an aqueous solution at a pH of about 7.5 to about 11.5 to free at least a significant portion of said proteinaceous deposit from said substrate and removing said proteinaceous deposit reduced substrate from said solution.</p> |
