Castor Oil 225 kg

What Keeps Castor Oil in High Demand Across Global Manufacturing Lines

Castor oil is pressed from castor beans and owes its dense texture and moisture-binding properties to a high concentration of ricinoleic acid, which explains why its applications reach far beyond skincare. This 225 kg drum belongs to the Bulk Oils section, curated for manufacturers running continuous production lines that require dependable, large-volume raw material supply rather than occasional small purchases.

The largest share of global castor oil consumption comes from the chemical and pharmaceutical industries rather than cosmetics alone. It serves as feedstock for biodegradable lubricants used in aviation and automotive engineering, brake and hydraulic fluids, plasticizers, and polyamide polymers such as nylon-11. In pharmaceutical manufacturing, castor oil functions as an auxiliary ingredient in ointment bases, suppositories, and capsule formulations, helping dissolve active substances and achieve the required consistency of the finished dosage form. The textile industry relies on it as a spinning lubricant for fiber processing, while printing and coatings manufacturers add it to inks and alkyd varnishes to improve flexibility and film formation.

Within cosmetic manufacturing, castor oil remains a widely used ingredient in skin, hair, and lash care formulations, as well as in lipsticks, balms, and massage blends thanks to its film-forming and moisture-locking properties.

For large-scale production, castor oil is frequently blended with other base oils to fine-tune the technological properties of the final mixture. In lubricant and coolant formulations, it is paired with Mineral Oil WP350 165 L to achieve stable viscosity across varying operating temperatures. In cosmetic emulsions, castor oil is commonly combined with Cosmetic Jojoba Oil 50 L, which lightens the dense texture of the formula and improves emulsion stability during storage. For technical and polymer-based compositions requiring a neutral mineral carrier, manufacturers pair it with Mineral Oil 100 L.

In skin and hair care formulations, castor oil is typically dosed between 5 and 30 percent of the total formula weight, while in technical blends the ratio depends entirely on the required viscosity and the specific manufacturing task. It is introduced into the oil phase at a heating temperature of 70-75 degrees Celsius, avoiding higher temperatures that could degrade active compounds and alter viscosity. The 225 kg volume should be stored in sealed containers, away from direct sunlight, in a dry area at temperatures not exceeding 25 degrees Celsius to preserve product stability throughout the entire production cycle.

Industrial-Scale Barrier Balm Base

Castor Oil 9000 g

Mineral Oil 100 L base 5000 g

Beeswax substitute 2000 g

Emulsifying wax 1200 g

Distilled water 40000 ml

Preservative blend 400 g

Melt the castor oil, mineral oil, beeswax substitute, and emulsifying wax together at 75 degrees Celsius until fully combined, then heat the water separately to the same temperature and slowly pour it into the oil phase while mixing continuously with a homogenizer. Cool the batch to 40 degrees Celsius, blend in the preservative and fragrance, mix until uniform, and transfer the finished balm base into industrial containers for downstream packaging.
