What is castor seed oil?

Castor seed oil is a plant oil pressed from the seeds of Ricinus communis. It is a triglyceride oil with a distinctive fatty acid profile, largely made up of ricinoleic acid, which gives castor oil its thicker texture and unique feel on skin.

What does castor seed oil do for the skin?

Castor seed oil works mainly as an emollient, helping to soften the skin and reduce moisture loss by forming a protective oil layer on the surface. Its naturally viscous texture also adds richness and cushioning to skincare formulations.

Is castor seed oil suitable for dry skin?

Castor seed oil can be helpful for dry skin because it reduces transepidermal water loss when used as part of a blend or balm. Many people prefer it combined with lighter oils to improve spreadability.

Is castor seed oil good for sensitive or reactive skin?

Many people tolerate castor oil well, but individual skin responses vary. Because it is a thick oil, it is best introduced gradually and patch tested first, especially for highly reactive skin.

Will castor seed oil clog pores?

Comedogenic ratings are not a perfect predictor of how skin will respond. Castor oil can feel heavy for some skin types, so acne-prone users often prefer it at low percentages within a blend.

How is castor seed oil commonly used in skincare formulations?

Castor oil is commonly used to add viscosity, gloss, and slip. It is frequently found in cleansing oils, balms, lip products, and body oils where a richer, more protective texture is desired.

How do I use castor seed oil at home?

Castor seed oil is often best used as part of a blend rather than on its own. Mixing a small amount with lighter carrier oils can reduce tackiness and improve spread before applying a thin layer to slightly damp skin.

Is castor seed oil safe to use during pregnancy?

For topical use, castor seed oil is commonly used in cosmetic and personal care products. Patch testing and conservative use are sensible during pregnancy. Castor oil should not be ingested unless advised by a qualified health professional.

Does castor seed oil have a strong scent?

Castor seed oil typically has a mild, slightly nutty to earthy aroma. In most blends it does not dominate and can be easily scented if desired.

How should castor seed oil be stored?

Castor seed oil should be stored tightly sealed, away from heat and direct sunlight and ideally in glass. Keeping it cool and limiting air exposure helps maintain freshness.

Is castor seed oil used for hair or eyelashes?

Castor seed oil is commonly used in hair and lash care because its thick texture helps coat and condition the hair shaft, reducing dryness and breakage. While it is widely used to improve the appearance and feel of hair and lashes, there is limited clinical evidence that it directly stimulates new hair growth.

Castor oil is valued in cosmetic formulation for its deeply nourishing, occlusive nature. Rich in ricinoleic acid, it helps support skin hydration, comfort, and barrier function, making it especially useful for dry, rough, or compromised skin. It is commonly used in balms, ointments, and massage oils where long lasting moisture and skin conditioning are desired.

Applied to the ends of dry hair, castor oil helps soften, protect, and reduce the appearance of split ends. It is also widely used in traditional castor oil packs as part of self care and massage rituals.

This oil is extracted using a cold press process only, with no chemical solvents used at any stage.

Packaging note
Our 1L and 5L sizes are supplied in food grade, cosmetic approved HDPE bottles. For those who prefer glass, we recommend decanting into a glass container and storing away from light.

Traditional context
Castor oil has a long history of traditional external use across many cultures, including Ayurvedic practices in India and folk remedies in parts of Europe and the Canary Islands. These historical uses form part of the cultural background of castor oil, though modern use is primarily focused on topical skin and hair care.

Safety note
This oil is intended for external use only. Castor oil is best applied to intact skin or used as part of cosmetic formulations. It is not recommended for use on open, infected, or non healing wounds. If a skin concern persists or worsens, advice from a qualified healthcare professional is recommended.

Castor Seed Oil Review

Thank you for my purchase of the Castor Oil. I have started using it in conjunction with baking soda to try and heal a small wound which has been very stubborn so I am waiting to see if it helps. Any other suggestions would be gratefully received.
I was a little surprised that it came in a plastic container instead of glass as I have been led to believe that the plastic can leech into the product.
Other than that, it is early days but I have used castor oil in the past and it has a multitude of good benefits.

Castor oil

Fantastic to deal with and fast delivery 😀

Fantastic product and service.

Beautiful product,Zurma you should be very proud of your castor oil well packaged and it’s working already. Thank you.

Clinical trial

Following recent research from Auckland University on the potential benefits that cold-pressed Castor Oil may have for the eyes, I contacted Zurma for information. The team were knowledgeable and helpful with regard to fulfilling my order requirements. I felt the product I bought was ethically sourced and produced with a team willing to listen and learn.
There are so many bogus suppliers online that I find it essential to source a company that is trusted and puts the customer first.
I would highly recommend Zurma and feel safe shopping there again.

Recommendation from a Friend

Did not know very much about this product but I read everything on your web page. So I thought to give it a try. I rub the Frankincense and castor oil into my operated knee (I have had a knee replacement) every day two or more times and have noticed quite an improvement. More flexibility and not so much pain. Early days yet, but it seems to be working! I love that you put it all in bottles, I also bought Comfrey and Castor oil and just Castor oil, and great web-site. Thank you Zurma
