Abstract
The influence of different surfactants on the possibility to obtain fine dispersions with a comparatively high percentage of cellulose acethophthalate (CAP) has been investigated. A method for obtaining concentrated dispersions of CAP including the anti-glaucoma drug pilocarpine hydrochloride has been proposed.
Thin liquid films formed from aqueous CAP dispersions on a glass surface have been investigated as a model of tear films in the eye. The film thickness has been determined by the microinterferometric method. The kinetics of thinning has been studied and discussed.
