Patent ID: 7951387

Claim:
An eyelid scrub composition comprising: polyhexamethylene biguanide; 1,2-hexanediol; 1,2-octanediol; about 60 wt. % to about 98 wt. % modified Ringer's solution: and a surfactant solution comprising: one or more amphoteric surfactants present in an amount effective to control a pH of the composition to within a desired pH range, the one or more amphoteric surfactants comprising: one or more pH compensating surfactants comprising about 0.1 wt. % to about 25 wt. % cocoamphodiacetate disodium, the surfactant solution further comprising: a mixture of one or more foam-producing surfactants comprising at least one of: about 0.1 wt. % to about 10 wt. % polyoxyethylene-80 sorbitan monolaurate: and about 0.2 wt. % to about 10 wt. % decyl polyglucoside, wherein an amount and a type of each of the pH compensating surfactants is determined based on a measured pH of the mixture of foam-producing surfactants.
