Product Description
Our Refined Milk Thistle Seed Oil is pressed from the seeds of Silybum marianum grown in Hungary and Austria, then refined to a clear, pale yellow oil with almost no scent. Rich in linoleic acid, it has a light, silky feel and absorbs quickly without leaving a greasy finish.
It works well in face oils, serums, creams, lotions and balms, and as a light conditioning oil in hair care. Because it is refined and near-odourless, it won't compete with your fragrance or essential oils, and its pale colour keeps white creams white.
As a high-linoleic oil, it benefits from an antioxidant such as Vitamin E and should be stored cool and sealed. Available from 1 kg up to drums and 1,000 kg IBCs for brands and contract manufacturers producing at scale.

Frequently asked questions
What is refined milk thistle seed oil?
It is the fixed oil pressed from the seeds of milk thistle, Silybum marianum (INCI: Silybum Marianum Seed Oil), then refined to give a pale, mild-smelling oil. It is a light, fast-absorbing carrier for face and body care.
How does refined milk thistle oil differ from cold pressed?
Refining removes much of the natural colour, odour and free fatty acids, giving a lighter, more neutral and consistent oil that sits easily in fragranced or lightly coloured formulas. Unrefined oils keep more of their seedy aroma and colour.
Where does it come from and can it be used in food?
It comes from milk thistle of Hungarian and Austrian origin. This grade is for cosmetic use only and is not intended for food.
What pack sizes are available?
From 1 kg up to a 1000 kg IBC, including 25 kg and 190 kg drums, all priced online. For regular volumes, ask us for a bulk quote.
