Vetiveria Zizanoides (Vetiver) Root Oil
Vetiveria zizanioides · INCI Vetiveria Zizanioides Root Oil
Vetiver root oil carries a set of identified antioxidant compounds, the vetivones chief among them, and the studies that found them tested the same steam-distilled root oil we use rather than some adjacent material. That is rarer than it sounds.
No ingredient is added for fragrance but vetiver brings a lovely bonus scent to our products on top of its main function.
What it is
Vetiver is a tall tussock grass, a cousin of sorghum and lemongrass, and the aromatic part of it is underground. The leaves smell of very little. The roots, which grow downward in a dense fibrous mass rather than spreading sideways, hold the oil, and getting it out is slow work. The roots are dug, washed, dried, and then steam is passed through them for six hours or more, because the oil sits deep in the root tissue and has to diffuse out. A tonne of roots yields a few kilos of oil. It is one of the reasons vetiver is so expensive.
What comes off the still is thick, brown, and slow to pour, and it smells earthy and woody with a smoky edge that some people take a while to warm to. Chemically it is unusual. Most essential oils are dominated by one or two compounds, whereas vetiver runs to well over a hundred, almost all of them sesquiterpenes, with no single constituent accounting for much more than a tenth of the whole. That complexity is why perfumers use it as a base note and why it has taken analytical chemists decades to map it properly.
Ours is an organic oil from Java, distilled from roots grown there, and it goes into every product in the range at between one and three parts in a thousand. On the label it is Vetiveria Zizanioides Root Oil.
What it does in our formulas
Two things, honestly stated.
An antioxidant note
Alpha and beta-vetivone and beta-vetivenene are the constituents the research picks out, and the oil we buy contains them. They work alongside the tocopherol to work in the formula.
Emerging evidenceIts scent
Earthy, woody, a little smoky, and quiet. A bonus feature, not the reason it is included.
Well characterisedWhat the research does not show
Two things to be straight about.
Marketed as A calming, antimicrobial, active
Marketed as Our products are fragrance-free, or free from essential oils
So: vetiver essential oil, in every product. If that is a problem for your skin, we would rather you knew before you bought something than after.
On the label and in the range
Vetiver appears in every one of our formulations, near the end of the ingredient list, at between a tenth and a quarter of a percent. On the label it reads by its INCI name, and it is marked to show it is an essential oil, because you should be able to see that at a glance. The exact percentage is published on each product page.
Is it suitable for me?
Vetiver is an essential oil, and essential oils can cause allergic reactions in a small number of people. If you know that essential oils irritate your skin, our products contain one, in every formula, and you should treat them accordingly. It suits a vegan routine, and none of that changes the paragraph above.
Vetiver is an essential oil, and essential oils can cause allergic reactions in a small number of people. Vetiver is one of the very few essential oils that don't have notifiable allergens. If your skin reacts easily, or you react to fragrance or essential oils, patch test first, or choose a product without them.
