What the register lists it for
These are the uses the European Commission’s CosIng register lists for Citronellol 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.
- Perfuming
-
Used as a perfume or scent material. Essential oils and their scent compounds, such as linalool and limonene, carry this role.
Register definition: “Used for perfume and aromatic raw materials.”
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.
