Salicylic acid is a carboxylic acid, meaning it will donate a hydrogen ion if a base pair accepts it. The reaction is true for both organic and inorganic bases. When it reacts with a base, it is termed a neutralization reaction, and this reaction gives off heat in the process. Salicylic acid is used in the topical form to treat and prevent acne and other blemishes to the skin. It can also treat conditions caused by the overgrowth of skin cells, such as psoriasis, dandruff, calluses and warts.
