Aspirin can be made by reacting salicylic acid with acetic acid in the presence of an acid catalyst. The phenol group on the salicylic acid forms an ester with the carboxyl group on the acetic acid. However, this reaction is slow and has a relatively low yield.To prepare aspirin, salicylic acid is r

Salicylic acid is derived from willow bark, says cosmetic chemist Ron Robinson, and it belongs to a class of ingredients called salicylates. It's structure is a little complicated, but understanding it is important to learning why (and how) it works so well.When it comes to skin-care products, ther

Salicylic acid is an organic compound with the chemical formula HOC6H4COOH. It is a colorless, bitter-tasting solid that is a precursor and metabolite of aspirin (acetylsalicylic acid). It is a plant hormone,[9] and has been listed as an experimental teratogen on the EPA Toxic Substances Control Ac
