Abstract

Contact lens treating solutions are obtained by dissolving in bulk in purified water a solid, preferably powdered, composition comprising chlorhexidine or a salt thereof, an alkali metal or ammonium salt of a hydroxyalkanic carboxylic acid and a vehicle. The alkali metal or ammonium salt does not hinder the dissolution of chlorhexidine or salt thereof, which usually is hindered when using an inorganic electrolyte salt as the buffering agent. Preferably chlorhexidine gluconate, sodium gluconate and sorbitol are used with the sodium gluconate and sorbitol substantially constituting the composition in a ratio by weight of about 2:1.
