Salicylic acid is a colorless, crystalline organic Carboxylic Acid . It is usually prepared by Kolbe synthesis (aka Kolbe-Schmitt Reaction ). Salicylic acid functions as a Plant Hormone . PROPERTIES Salicylic acid is toxic if ingested in large quantities, but in small quantities is used as a Food Preservative and Antiseptic in Toothpaste . The Carboxyl Group (–COOH) can react with Alcohols , forming several useful Ester s. The ester with Ethanol is Ethyl Salicylate , also known under the name ''oil of wintergreen''. The group (–OH) can be acetylated to form acetylsalicylic acid (aspirin). Salicylic acid can also trap oxygen (O2) and initiate free radical reactions. MEDICINAL AND COSMETIC USES Also known as Beta Hydroxy Acid (compare to AHA ), salicylic acid is the key Additive in many skin-care products for the treatment of Acne , callouses and corns, Keratosis Pilaris and Wart s. It treats acne by causing skin cells to slough off more readily, preventing Pore s from clogging up. This effect on skin cells also makes salicylic acid an active ingredient in several Shampoo s meant to treat Dandruff . Use of straight salicylic solution may cause hyper-pigmentation on unpretreated skin for those with darker skin types (Fitzpatrick phototypes IV, V, VI), as well as with the lack of use of a broad spectrum sunblock. The medicinal properties of salicylate (mainly for Fever relief) have been known since Ancient Times . The substance occurs in the bark of Willow trees; the name ''salicylic acid'' is derived from ''salix'', the Latin name for the willow tree. pads soaked in salicylic acid can be used to chemically Exfoliate skin]] Aspirin (acetylsalicylic acid or ASA) can be prepared by the Esterification of the phenolic hydroxyl group of salicylic acid. Subsalicylate in combination with Bismuth form the popular stomach relief aid known commonly as Pepto-Bismol . When combined the two key ingredients help control Diarrhea , nausea, heartburn, and even gas. It is also very mildly anti-biotic. SALICYLIC ACID AS A PLANT HORMONE Here is a list of some of salicylic acid's properties when acting as a Plant Hormone . It is interesting to note, in light of these properties, that there is a popular belief that cut flowers will last longer if Aspirin (acetylsalicylic acid) is dissolved in their water.
