Тимол
Sharp, hot, phenolic-herbal with an aggressive medicinal bite. Thymol smells like concentrated thyme extract — pungent, warm, and deeply antiseptic.

Цікавий факт
Thymol is one of four essential-oil ingredients, with eucalyptol, menthol and methyl salicylate, in an antiseptic formula created in 1879 by the St. Louis chemist Joseph Lawrence. First intended for surgery, it was promoted to dentists in 1895 and in 1914 became the first mouthwash sold over the counter in the United States.
Отримання й хімія
Спосіб отримання
Isolated from thyme oil by fractional distillation and crystallization. Thyme oil of the thymol chemotype contains 35-55% thymol. Also produced synthetically from meta-cresol and propylene. Natural isolation is commercially viable due to thymol's high concentration in thyme oil.

У парфумерії
Trace modifier in herbal and aromatic compositions. Thymol is used at very low concentrations (below 0.1%) to add authentic thyme character. Its phenolic aggression limits dosage in fine fragrance. More common in functional fragrance (dental products, household cleaners) where its antimicrobial properties are valued alongside its scent. In perfumery, it provides the 'hot herb' accent that dried thyme adds to cooking — a small amount transforms the composition.
