Cederroth buffered Eye Wash works to neutralize the pH value of the eye, i.e. it has a neutralizing effect on splashes of alkalis and acids, which gives faster results than with regular saline solution. The effect is generally stronger for alkalis than for acids. If an accident has occurred with calcium-containing substances (for example cement, concrete or lime), you can safely rinse with Cederroth Eye Wash because it is 100% phosphate-free for optimal rinsing. An easy-to-handle bottle with an ergonomic eye cup and generous flow of liquid. Quick and easy to open. Shelf life of a full 4.5 years.
