In short: Japanese mint oil is distilled from Mentha arvensis and is very rich in menthol (crude oil often above 70%), with a sharp cooling smell; it is used mainly to produce menthol and in balms and cooling products. Peppermint oil comes from Mentha × piperita, has less menthol (about 30–45%) plus menthone, and a rounder, sweeter aroma favoured for food and toothpaste. They are not fully interchangeable.
| Criterion | Japanese mint oil | Peppermint oil |
|---|---|---|
| Plant | Mentha arvensis (Asian mint) | Mentha × piperita |
| Menthol | Very high in crude oil; about 30–40% after dementholisation | About 30–45% |
| Aroma | Strong, sharp cooling | Softer, rounder, slightly sweet |
| Main uses | Menthol production, balms, cooling products | Food flavouring, toothpaste, confectionery, cosmetics |
| Main producers | India, China | USA, Europe |
The two oils differ in composition, so their uses differ too. Some products sold as “peppermint oil” are actually Asian mint oil. Check the botanical name on the label and the GC-MS report: the ratio of menthol, menthone and marker compounds tells you which oil it is.
Japanese mint oil usually feels stronger because of its higher menthol content. Both are concentrated and must be diluted – see mint oil safety.
Our oil is distilled from the SW88 Japanese mint variety grown in Phu Tho, Vietnam.
