Abstract: The use of monoacyl phosphoglycerides to enhance the penetration of topically applied ophthalmic drugs through the corneal epithelium is described.

Abstract: Latex compositions suitable for applications requiring surface hydrophilicity are disclosed. The compositions comprise: (1) a liquid phase selected from the group consisting of water, water-miscible solvents and mixtures thereof; and (2) latex particles dispersed in the liquid phase. The particles comprise an elastomeric hydrophobic core and a hydrophilic "shell" which is integral with the core and which colloidally stabilizes the latex particles in the liquid phase. The shell comprises moieties L-Q attached to the core, wherein Q is a nonionic group end-capped with a cationic moiety, and L is a linking unit. When the liquid phase is removed, the particles are capable of forming an elastomeric film having a substantially permanent cationic, hydrophilic surface. The cationic moiety helps the latex particles become attracted to anionic surfaces such as cellulosic materials.

Abstract: Latex compositions suitable for applications requiring surface hydrophilicity are disclosed. The latexes can be used in liquid film-forming compositions which comprise: (1) a liquid phase such as water, water-miscible solvents and mixtures thereof; and (2) latex particles dispersed in the liquid phase. The particles comprise an elastomeric hydrophobic core with a hydrophilic "shell" which is integral with the core. When the liquid phase is removed, the particles are capable of forming an elastomeric film having a substantially permanent hydrophilic surface.

Abstract: A density separation process for recovering vegetable seed protein granules from the remaining portion of the vegetable seeds, using an aqueous single-phase solution of an organic acid salt, said aqueous solution having a density of from about 1.2 to about 1.45 g/ml and a water activity of from about 0.40 to about 0.85.
