What it is
In the register’s words: “Linum Usitatissimum Seed Extract is an extract of the seeds of the Linseed, Linum usitatissimum L., Linaceae.”
- EU register name (INCI)
- LINUM USITATISSIMUM SEED EXTRACT
- CAS number
- 8001-26-1
- EC number
- 232-278-6
- Written on these labels as
- Linum Usitatissimum (Linseed) Seed Extract; Linum Usitatissimum (Linseed/Flaxseed) Seed Extract
Labels often add a second name in brackets, so a label may say Linum Usitatissimum (Linseed) Seed Extract where the register says LINUM USITATISSIMUM SEED EXTRACT. Both are the same ingredient.
What the register lists it for
These are the uses the European Commission’s CosIng register lists for Linum Usitatissimum (Linseed) Seed 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.
- 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.”
- 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.
- Shampoos 1 label First five names: 0 of 1 Shampoos without 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.
