What the register lists it for
These are the uses the European Commission’s CosIng register lists for Boswellia Carterii 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.”
- 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.
