Castor oil: properties, uses, and optimization of processing parameters in commercial production
Bioresource Technology, 2006
100% pure certified organic castor oil (Ricinus communis seed oil), cold pressed without chemical solvents, stored in a glass bottle to preserve purity and prevent plastic leaching. Single ingredient. No additives, preservatives, artificial colours, or fragrances. For external use on skin, hair, scalp, eyebrows, and lashes.
Certified organic. Hexane free. Vegan. Non-GMO. Sourced from India. Made in Canada.
A single-ingredient, 100% pure certified organic castor oil stored in a glass bottle. The oil is cold pressed from the seeds of Ricinus communis, the castor plant native to tropical regions of Africa and Asia, sourced from India.
Cold pressing uses mechanical pressure to extract oil from the seed without chemical solvents or external heat. This preserves the natural fatty acid composition of the oil and eliminates the risk of hexane residues present in solvent-extracted oils. Glass bottle storage prevents the migration of plasticizers and other compounds from plastic packaging into the oil over time.
For external use only. Not for internal consumption. Vegan. Non-GMO. No additives of any kind.
Castor oil contains approximately 85 to 90% ricinoleic acid, a hydroxyl fatty acid that is exceptionally rare in nature and not found at significant concentrations in any other commercially available vegetable oil. The hydroxyl group at the 12-carbon position of ricinoleic acid gives castor oil its characteristic high viscosity, strong humectant properties, and ability to penetrate the skin barrier more deeply than most other fixed oils. This unique fatty acid profile is the basis for castor oil's longstanding use in topical skin and hair care.
Conventional castor oil production often uses hexane, a petrochemical solvent, to maximize oil yield from the seed. Hexane extraction leaves trace solvent residues in the finished oil and does not require the same quality controls as mechanical pressing. Cold pressing uses mechanical pressure alone, with no chemical solvents introduced at any stage. The result is a cleaner oil with no solvent residues and a fully preserved natural fatty acid profile.
Castor oil is a highly viscous, lipophilic oil that can interact with plastic packaging over time, potentially drawing plasticizers and other polymer additives into the oil. Glass is chemically inert and does not leach compounds into the oil regardless of storage duration or temperature. Glass also provides superior protection from light and environmental contamination, and is fully recyclable. Storing castor oil in glass preserves purity from production through to the last drop.
Castor seeds are grown in tropical agricultural systems where synthetic pesticide and herbicide use is common in conventional production. These compounds are lipophilic and can concentrate in the seed oil during extraction. Certified organic certification prohibits synthetic pesticide and herbicide use at every stage of cultivation and processing, providing meaningful purity assurance for an oil applied directly to skin, scalp, and sensitive areas such as the eye contour.
No non-medicinal ingredients. Single ingredient only. No additives, preservatives, artificial colours, or fragrances.
Skin: Apply a small amount to clean, dry skin and massage gently until absorbed. Suitable for face and body. Can be used alone or blended with a lighter carrier oil.
Hair and scalp: Apply to the scalp and hair. Leave on for at least 30 minutes or overnight for deeper conditioning. Wash out with shampoo. Use 1 to 2 times per week or as needed. Due to its thick texture, castor oil is easier to apply when slightly warmed (place the glass bottle in warm water for a few minutes) or blended with a lighter oil such as coconut or jojoba.
Eyebrows and lashes: Using a clean brush or applicator, apply a small amount to eyebrows or lash line before bedtime. Remove in the morning with a gentle cleanser. Avoid direct contact with eyes.
Store in a cool, dry place away from direct sunlight. Keep bottle tightly sealed after each use. The glass bottle protects the oil from light and environmental contamination. Do not refrigerate. Castor oil has a long shelf life when stored properly.
For external use only. Do not ingest. Keep out of eyes. If contact with eyes occurs, rinse thoroughly with water. Perform a patch test on a small area of skin before first use, particularly if you have sensitive skin or known allergies. Discontinue use if irritation occurs. Keep out of reach of children.
