Application of a composition of matter comprising a solution of water in relatively nontoxic water-stable ethylenically unsaturated monomers, preferably methacrylate and/or acrylate and most preferably methacrylate monomers, which solution is substantially isotonic with normal physiological saline solution. As a further aspect of the invention, the compositions may be prepared by selecting ethylenically unsaturated monomers of varying hydrophilicity or water solubility, equilibrating each such monomer with water to form a two phase system and measuring the concentration of the monomer in the water-rich phase, preparing a mixture of monomers in equilibrium with water such that their cumulative concentration in the water phase is about 0.31 molar, and collecting the monomer-rich phase, which will be saturated with water and will also be isotonic with normal physiological saline.
