Premium Grade Tea Tree Oil is MCNE’s flagship product distilled from the plantation crops at our Northern NSW estate. This grade of oil is characterised by very low p-cymene and cineole content along with comparatively very high levels of the terpinen-4-ol content. Premium Grade simply arises from M. alternifolia plants that have been carefully selected and propagated throughout much of the plantation. Nature has dictated the premium composition – no additional processing is applied beyond the single-pass steam distillation of freshly harvested plants.
Complete compositional results of each batch will be provided separately alongside corresponding British Pharmacopeia 2016 specification for Australian tea tree oil. MCNE’s Premium Grade Tea Tree oil meets the British Pharmacopeia 2016 specification.
