What it is
In the register’s words: “Mentha Piperita Oil is the volatile oil obtained from the whole plant of the Peppermint, Mentha piperita (L.), Labiatae.”
- EU register name (INCI)
- MENTHA PIPERITA OIL
- CAS number
- 8006-90-4 / 84082-70-2
- EC number
- - / 282-015-4
- Written on these labels as

Labels often add a second name in brackets, so a label may say Mentha Piperita (Peppermint) Oil where the register says MENTHA PIPERITA OIL. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Mentha Piperita (Peppermint) Oil in any cosmetic, hair roles first. They say why a maker might add it, not what it does in one formula, and they aren’t a safety rating.
- Fragrance
-

Register definition: “Imparting a pleasant freshness to the skin.”
- Tonic

The register’s role for ingredients said to give skin and hair a feeling of well-being. Many plant extracts carry it.
Register definition: “Producing a feeling of well-being on skin and hair.”
Where it sits on each label
US labels list ingredients from most to least, except that those at 1% or less may follow in any order. A name near the top is a large part of the formula. A label doesn’t mark where the 1% point falls, so further down, the order says little about how much is in it.
