Abstract
A method for producing a silicone hydrogel may include: (1) preparing a curable composition containing a silicone-based(meth)acrylate (A), a hydrophilic monomer (B), and a surfactant (C); (2) molding the curable composition with a hydrophobic mold to obtain a cured product; and (3) washing the cured product. The silicone-based(meth)acrylate (A) may be a monomer having a siloxanyl group in a molecule. The hydrophilic monomer (B) may include a first monomer including, in a molecule, a hydroxyl group, an amino group, a carboxyl group, an ionic group, a pyrrolidone group, an amide structure, and/or a polyalkylene oxide group.
