What it is
In the register’s words: “Rosmarinus Officinalis Leaf Oil is the essential oil obtained from the flowering tops and leaves of the Rosemary, Rosmarinus officinalis L., Lamiaceae.”
- EU register name (INCI)
- ROSMARINUS OFFICINALIS LEAF OIL
- CAS number
- 84604-14-8 / 8000-25-7
- EC number
- 283-291-9
Labels often add a second name in brackets, so a label may say Rosmarinus Officinalis (Rosemary) Leaf Oil where the register says ROSMARINUS OFFICINALIS LEAF OIL. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Rosmarinus Officinalis (Rosemary) Leaf 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
-
Gives the product its smell or covers an unpleasant one. A label may name each scent ingredient or group them as Fragrance (Parfum).
Register definition: “Imparting an odour or taste. Creating a perceivable pleasant smell and/or masking a bad smell.”
- 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.

Each line runs from the first name on a label to the last; a dot is where this ingredient sits. Makers change formulas now and then; if the list on your bottle differs, go by your bottle.
