Castor oil for skin and lips – what this thick oil does in natural cosmetics

Ricinoleic acid sets it apart

Castor oil is pressed from the seeds of the castor oil plant (Ricinus communis). Up to 90% of its fatty acids are ricinoleic acid, a fatty acid with an extra hydroxyl group. Among plant oils, that is unusual.

This fatty acid makes the oil much thicker than most plant oils and comparatively resistant to going rancid.

A film on skin and lips

Because it is so thick, castor oil stays on the skin as a glossy film. This film helps protect against drying out and keeps rough, dry areas supple, for example on the lips, hands or heels.

It absorbs slowly, which is why it is usually blended with other oils, butters and waxes.

Shine in lip care

In lipsticks and lip balms, castor oil adds shine and glide. According to a safety assessment by the Cosmetic Ingredient Review (2007), it is used in lipsticks at concentrations of up to 81%.

In salves, it makes the mixture softer and easier to spread. In bar soaps, it turns into soap itself during saponification.

Castor oil

Castor oil is rich in ricinoleic acid and forms a dense, glossy film on the skin. This helps protect dry skin from drying out and keeps chapped lips supple.

At forpeople, according to the ingredient lists, it is found in the Beeswax Salve and the bar soaps: see products with castor oil.

Origin

Castor oil is obtained from the seeds of the castor oil plant (Ricinus communis). Most of it comes from India, which accounts for over 90% of global exports; the plant is also grown in Africa and South America. For cosmetics, the seeds are usually cold-pressed.

The seeds contain ricin, a toxic protein. It does not pass into the oil. Our castor oil comes from certified organic farming.

100% Organic

We use organic castor oil from certified organic farming. Under the EU organic regulation, chemically synthesised pesticides and mineral fertilisers are generally not permitted.

According to the ingredient lists, it is found in our Beeswax Salve (glass jar and tin) alongside olive and almond oil, and in the bar soaps. The Beeswax Salve also contains larch resin and propolis; see our allergy notes.
