Virgin castor oil from cold pressing, Certified COSMOS ORGANIC, 5L
The castor plant (Ricinus Communis) originates from India and Egypt, and it was initially known as the "Palm of Christ" because its leaves resemble hands and its small miracles are numerous. Throughout history, it has been used as a makeup remover, purgative, anti-arthritis remedy, and even as fuel for oil lamps !
🔻 Virgin castor oil 5L Biovie is a 100% pure vegetable oil derived from castor seeds.Ricinus communis) grown in India, then cold-pressed without solvents or chemicals. Certified COSMOS ORGANIC certified by ECOCERT and COSMEBIO, it is intended for exclusive cosmetic use: care for hair, eyelashes, eyebrows, nails, and dry skin.
The 5L format, the most economical per liter in our range, is aimed at families, enthusiasts of natural beauty routines, and professionals (hair salons, institutes, homemade cosmetics creators).
A tablespoon of castor oil on the lengths before shampooing, two drops on the eyelashes each night, a quick massage on the nails before sleeping. This is what a simple castor oil routine looks like. Its texture is thick—thicker than most vegetable oils—and this is precisely what makes it an outstanding enveloping treatment for areas that need it.
Hair care remains the flagship application. In pre-shampoo mask, Castor oil nourishes the hair fiber and soothes the scalp. To facilitate application (as its texture is naturally thick), I recommend mixing it in equal parts with a more fluid oil - jojoba, hemp, camelina, or argan work very well. Distribute on lengths and ends, leave on for 30 minutes to overnight, then rinse with a gentle shampoo. One to two applications per week are sufficient.

One drop each evening on the eyelashes and eyebrows, applied with a clean fine brush. A washed old mascara brush works perfectly (yes, that's exactly what we use at home). Expect 6 to 8 weeks of regular use to achieve fuller eyelashes and better-defined eyebrows. It's one of the simplest treatments to implement—and one of the most visibly effective over time.
Massage 1 to 2 drops on each nail and cuticle in the evening before bed. Nails regain flexibility and strength after a few weeks. Practical tip: if you work a lot with your hands and the cuticles get damaged, the same routine works wonders.
Softening and nourishing, castor oil is particularly suitable for very dry skin, rough hands, cracked feet, and dry elbows and knees. Apply it pure or diluted in equal parts with sweet almond oil on the area, then massage until absorbed. You will find the skin more supple from the first applications.
On a washable cotton pad, apply a few drops of pure oil or oil diluted in sweet almond oil. Castor oil effectively dissolves the most stubborn makeup - waterproof mascara, long-lasting lipstick - without irritating the skin. A simple cosmetic alternative to conventional makeup removers.
If you make your own skincare products, organic castor oil is a remarkable basic ingredient: solid shampoos, lip balms, body butters, DIY care oils. The 5L format provides an ideal supply for regular creators - we've seen it with several customers who produce their homemade cosmetics all year round without needing to restock along the way.

What sets castor oil apart from other vegetable oils is its exceptional concentration of Ricinoleic acid - between 80 and 92% of its total composition. This rare fatty acid is the source of its nourishing and strengthening properties recognized in cosmetics. No other common vegetable oil reaches such a level. This explains its very particular texture, both enveloping and adherent on the fiber.
Castor oil helps to nourish the hair fiber, reduce breakage, and protect the ends. It helps to bring suppleness and shine to dry, damaged, or frizzy hair. When massaged onto the scalp, it contributes to the comfort of sensitive scalps.

Thanks to its enveloping texture, castor oil promotes density of eyelashes and eyebrows and strengthens brittle nails. A daily application, even minimal, is enough to achieve visible results after a few weeks. Honestly, it's one of the simplest natural cosmetic treatments to incorporate into a routine.
Softening, repairing, and nourishing, it is ideal for dehydrated skin, dry hands, and feet. It can be used in localized massages or diluted in a more fluid oil for increased comfort over larger areas.
Its creamy texture dissolves even the most stubborn makeup while respecting the skin's balance. It is a healthy cosmetic alternative to conventional makeup removers - and a use that I frequently see mentioned in customer feedback.
The 5L can of organic castor oil is the most economical format in our range per liter. It is primarily intended for:
- to the families who regularly use castor oil for care for several people.
- to the beauty professionals - hair salons, institutes, home beauticians.
- to the homemade cosmetics manufacturers who produce shampoos, balms, and care oils all year round.
- to the passionate about natural beauty routines who are looking for long-lasting autonomy without having to make frequent purchases.
> For more occasional use or to test before investing in the large format, the 500 ml bottle remains more suitable.

The incredible benefits of castor oil for your beauty
🌟 "The ordered product (5L castor oil) is of high quality with a very good quality-price ratio. Delivered in excellent condition and in a short time."
— Amrita, Biovie customer ⭐⭐⭐⭐⭐
Castor seeds are grown in India according to organic farming standards, then pressed to extract a virgin cold-pressed oil. The seeds are preheated to 82°C for 30 minutes to denature ricin (a toxin naturally present in the raw seed) - a mandatory step that ensures the cosmetic safety of the final oil.
Cold pressing by hydraulic press does not require neither solvent nor chemical product, which guarantees a 100% natural and pure oil. No subsequent heat treatment is applied: all the initial cosmetic properties of the oil are thus preserved.
This oil benefits from a double certification: COSMOS ORGANIC by ECOCERT and COSMEBIO, ensuring a controlled organic supply chain from the seed to the bottle.
• Hair and scalp : pre-shampoo mask, pure or mixed
• Nails : 1 to 2 drops per nail, daily massage at bedtime
• Eyelashes and eyebrows : apply with a fine brush each evening
• Dry skin : localized massage, pure or diluted in sweet almond oil
• Makeup remover : on washable cotton, pure or diluted
• Homemade cosmetics : basic ingredient for natural shampoo
In external cosmetic use, organic castor oil is generally very well tolerated. The CIR Expert Panel (2007, PMID 18080873) concluded that castor oil is safe under normal cosmetic and topical use conditions - this is the official safety reference for the cosmetic industry.
As with any natural cosmetic, I recommend to perform a preliminary skin test on a small area (such as the crook of the elbow) before the first use, to rule out any individual sensitivity reaction. If redness or itching occurs, discontinue use. There you go, a simple precaution that only takes 24 hours.
At Biovie, we distribute this Organic castor oil 5L since 2007 - which means 19 years of expertise in the industry by 2026. With Aurélie, we personally select the producers and have chosen this Indian supply chain for its consistent quality, batch after batch. For those who wish to compare the castor oils available on the market, we have written a Comparison of the best organic castor oils, and a guide for know where to buy high-quality organic castor oil.
As a pre-shampoo mask, use once or twice a week. Mix 50% castor oil with 50% of a lighter oil (jojoba, hemp, argan), apply to lengths and ends, leave on for 30 minutes to an entire night, then rinse with a gentle shampoo.
Castor oil helps to thicken and strengthen the fibers of eyelashes and eyebrows due to its richness in ricinoleic acid (80-92%). A daily application with a fine brush for 6 to 8 weeks allows for visible results.
Certified COSMOS ORGANIC organic castor oil ensures that the seeds were grown without synthetic pesticides or fertilizers, and that the extraction was done by cold pressing without chemical solvents. A non-organic oil may contain pesticide residues and be extracted using heat or solvents, which alters its cosmetic properties.
Yes, the 5L format is the most economical per liter in the range. It is particularly recommended for families, beauty professionals (salons, institutes), and homemade cosmetics creators. For occasional use, the 500 ml bottle is more suitable.
Keep the canister tightly closed, away from light and heat (cool room, closed cupboard). The best before date is 18 months after opening. Thanks to its richness in ricinoleic acid, castor oil is naturally stable and is not prone to rancidity.
