Properties

Salicylic acid is a lipophilic monohydroxybenzoic acid, a type of phenolic acid and a beta hydroxy acid. It has the formula C7H6O3. This colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone.

Pharmacology

In the context of its use as a medication, salicylic acid is known as a keratolytic. It works by increasing the amount of moisture in the skin and dissolving the substance that causes the skin cells to stick together. This makes it easier to shed the skin cells.
