When alkalis or acids get into the eye, the pH value of the eye changes and corrosion occurs. Cederroth’s borate-buffered liquid helps to bring the pH value back to neutral again, unlike an unbuffered eye wash, which simply dilutes and rinses. The eye has a neutral pH value (7). Acids have a low pH value and alkalis have a high pH value. This is why Cederroth Eye Wash has been recommended by eye specialists in a study that compared the effect of different rinsing solutions on alkalis1.
