What it is
In the register’s words: “Arctium Lappa Root Extract is an extract of the roots of the Burdock, Arctium lappa L., Asteraceae.”
- EU register name (INCI)
- ARCTIUM LAPPA ROOT EXTRACT
- CAS number
- 84012-13-5
- EC number
- 281-658-8
- Written on these labels as
- Arctium Lappa (Burdock) Root Extract; Arctium Lappa Root Extract
Labels often add a second name in brackets, so a label may say Arctium Lappa (Burdock) Root Extract where the register says ARCTIUM LAPPA ROOT EXTRACT. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Arctium Lappa (Burdock) Root 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.
