Geraniol Oil is made up of molecules extracted from the essential oils of a combination of plants mainly those of the Rose, Geranium and Palmarosa species. It is also a component of other plant oils like lemon.
Geraniol Oil is a terpene alcohol, containing specific natural plant compounds which elude a vapour acting as an effective insect repellent. The aroma is not unlike that of pelargonium oil.
Heritage Oils uses Geraniol oil as a major active in your Mozz Away Skin Spray acting as a natural pest control repelling mozzies, midgies, sand flies and small irritating flying insects.
Geraniol Oil can be diffused in vaporisers inside homes to repel mosquitoes, especially when blended with either Lemon grass or Palmarosa.
Geraniol is used in many household products and cosmetic skin care and has been known to have anti-fungal agents. Much research is taking place on this amazing plant molecule with studies continuing on its anti-microbial, anti-inflammatory and anti-oxidant effects.
