It also contains poloxamine to help remove dirt and debris and enhance wettability and moisture retention for a more comfortable feeling throughout the day, as well as DYMED(R), which provides unsurpassed disinfection efficacy.
Another example is Clens 100 (Alcon, Fort Worth, Texas, USA), which contains polyethyl glycol-II (PEG-II) lauryl ether carboxylic acid as the surfactant and poloxamine as a wetting agent (note that this is also available as Clerz Plus lens drops for soft lenses only).
