    Hi all, 

    What are your opinions on o-cymen-5-ol
    I intend to include it in my face wash formulation for oily/acne-prone skin. 

    Should I use more common ingredients such as witch hazel or tea tree oil?

    o-cymen-5-ol is more commonly known as carvacrol - a common constituent of essential oils especially oregano.

    Very strong smell so if you want to go around smelling like a pizza - fine. If you don’t, best give it a miss.

    Remember, any hint of medicinal properties that you may make puts them in a new category of product.

    it’s related to thymol and carvacrol, but different to both, and it has much weaker odour than either

    the difference is most obvious from the IUPAC names:

    thymol: 2-isopropyl-5-methylphenol
    carvacrol: 5-isopropyl-2-methylphenol
    o-cymen-5-ol: 4-isopropyl-3-methylphenol

    in the EU it’s only permitted as a preservative, with a limit of 0.1% (minimum inhibitory concentrations are 0.02-0.07% depending on the species)

    @johnb @Bill_Toge Thank you for your input. I’ve seen it in many facial products which sparked my interested in working with it.
