The present invention relates to an antimicrobial composition and a method for disinfection involving the antimicrobial composition. It particularly relates to an antimicrobial composition for personal cleaning, oral care or hard surface cleaning applications. It was found that compositions comprising one or more isopropyl-methyl-catechols, terpineol and a carrier provide synergistic antimicrobial action. In a preferred aspect the composition also comprises 1 to 80 %-wt of one or more surfactants.

The present invention relates to a method for disinfection involving an antimicrobial composition, an antimicrobial composition suitable for use in such a method and antimicrobial compounds. It particularly relates to an antimicrobial composition for personal cleaning, oral care or hard surface cleaning applications. It was found that compositions comprising selected isopropyl-methylcatechols and a carrier provide antimicrobial action. In a preferred aspect the compositions of the invention also comprise 1 to 80 %-wt of surfactant.

(22%) and germacrene D (7.5%) as well as an important fraction of methoxylated monoterpenoids. They were mainly isomers of thymol methyl ether, accounting for 13% of the chromatogram. A new quantitatively important compound (9%) was identified through NMR and chemical synthesis as 4-isopropyl-6-methylbenzo[d][1,3]dioxole, and designated herzogole, alongside the minor related compound 1-isopropyl-2,3-d
useful for syntheses of catechol derivatives, it is hampered by many competing reactions and has not been developed as a useful methodology. Here, we succeeded in settling this problem by a first systematic thorough investigation, establishing the 1,2-rearrangement as a cascade reaction with a retro Diels-Alder reaction from o-quinol dimers. This is a useful strategy for syntheses of substituted catechols
