Salicylic Acid Powder, also known as salicylic acid, is more acidic than benzoic acid. It becomes darker in sunlight and becomes purplish red chelate when it encounters iron ions.

Salicylic acid is widely used, eczema, psoriasis, acne, dandruff may be used. Salicylic acid in concentrations of 3% to 6% can be used to exfoliate, while higher than 6% can be damaging to tissues.

Also found in cinnamon oil, violet oil, Holly oil. Only a small amount of free salicylic acid is present in plants. Salicylic acid has the duality of phenol and carboxylic acid. When heated, it sublimates, and when heated rapidly, it decomposes into phenol and carbon dioxide. When reacting with sodium hydroxide, hydroxyl and carboxyl groups are neutralized to form double salts. But with sodium carbonate, only the carboxyl group is neutralized to form a single salt. When reacting with alcohol or phenol, the corresponding salicylate ester can be formed. When acted with carboxylic acid or anhydride, corresponding carboxylic acid esters can be formed. This product is toxic, irritates the skin, mucous membrane, and can react with the protein in the body tissue, so it is corrosive. On the other hand, it can be sterilized.
