Definition
Meaning
A white crystalline compound derived from salicylic acid and phenol, used as an internal antiseptic and in sunscreens.
Salol is primarily known as a historical pharmaceutical and chemical compound. It was formerly used as an enteric coating for pills because it passes through the stomach unchanged and dissolves in the alkaline intestines, releasing salicylic acid.

Common Mistakes
