A phenolic fragrance compound with antioxidant properties but also skin sensitization potential, requiring careful concentration control.

Vinyl guaiacol (2-methoxy-4-vinylphenol) is a phenolic compound containing both a vinyl group and a methoxyphenol (guaiacol) moiety. It occurs naturally in clove oil and is used as a fragrance ingredient for its spicy, clove-like odor. Phenolic compounds can act as skin sensitizers in certain individuals, and vinyl guaiacol has been flagged in the EU as a potential contact allergen requiring declaration. Under Regulation (EC) No 1223/2009 and IFRA standards, certain phenol derivatives require sensitization precautionary labeling. The vinyl double bond adds structural reactivity that warrants caution.
