Guaiacol (/ ˈ ɡ w aɪ ə k ɒ l /) is an organic compound with the formula C 6 H 4 (OH)(OCH 3). It is a phenolic compound containing a methoxy functional group. Guaiacol appears as a viscous colorless oil, although aged or impure samples are often yellowish. It occurs widely in nature and is a common product of the pyrolysis of wood. [3]
It is a colorless solid, although typical samples are brown owing to air-oxidized impurities. Together with guaiacol, syringol and its derivatives are produced by the pyrolysis of lignin. Specifically, syringol is derived from the thermal decomposition of the sinapyl alcohol component. As such, syringol is an important component of wood smoke.
Research published in 2020 in the Journal of Drugs in Dermatology found that a 1% colloidal oatmeal eczema cream improved the skin’s microbiome composition by decreasing certain bacteria on the ...
Eugenol / ˈ j uː dʒ ɪ n ɒ l / is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. [2] It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove, nutmeg, cinnamon, basil and bay leaf.
Natural skin care uses topical creams and lotions made of ingredients available in nature. [1] Much of the recent literature reviews plant-derived ingredients, which may include herbs, roots, flowers and essential oils, [2] [3] [4] but natural substances in skin care products include animal-derived products such as beeswax, and minerals.
Later it was synthesized from lignin-containing "brown liquor", a byproduct of the sulfite process for making wood pulp. [12] Counterintuitively, though it uses waste materials, the lignin process is no longer popular because of environmental concerns, and today most vanillin is produced from guaiacol. [12]

Idealized structure of lignin from a softwood. Lignin is a class of complex organic polymers that form key structural materials in the support tissues of most plants. [1] Lignins are particularly important in the formation of cell walls, especially in wood and bark, because they lend rigidity and do not rot easily.
