What it is
In the register’s words: “Origanum Vulgare Leaf Extract is an extract of the leaves of the Wild Marjoram, Origanum vulgare L., Labiatae.”
- EU register name (INCI)
- ORIGANUM VULGARE LEAF EXTRACT
- CAS number
- 84012-24-8
- EC number
- 281-670-3
- Written on these labels as
- Origanum Vulgare (Oregano) Leaf Extract; Origanum Vulgare Leaf Extract
Labels often add a second name in brackets, so a label may say Origanum Vulgare (Oregano) Leaf Extract where the register says ORIGANUM VULGARE LEAF EXTRACT. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Origanum Vulgare (Oregano) Leaf Extract 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.
- Skin conditioning
-
The register’s broad role for ingredients that keep skin in good condition. On a hair label it often sits beside a hair role, or marks a plant oil or extract.
Register definition: “Maintaining the skin in good condition.”
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.

- Rinse-out conditioners 1 label First five names: 0 of 1 Rinse-out conditioners without it
