Castor Oil Supplier South Africa

Qu'est-ce que l'huile de ricin ?

Castor oil is a vegetable triglyceride oil extracted from the seeds of Ricinus communis. It is distinctive among natural oils for its exceptionally high ricinoleic acid content (85–90%), a C18 monounsaturated hydroxyl fatty acid (12-hydroxy-octadecanoic acid) that gives castor oil its unusual properties: high viscosity, film-forming ability, hygroscopicity (ability to attract and retain moisture), excellent miscibility with alcohols, and superior solubilising power for certain waxes and resins. These properties make castor oil a uniquely functional cosmetic ingredient.

Applications cosmétiques et de soins personnels

In lip care (lipsticks, lip glosses, lip balms), castor oil is the primary base oil — it provides gloss, high viscosity, pigment suspension, and the slightly tacky film characteristic of lip products. The hydroxyl group of ricinoleic acid makes castor oil a humectant as well as an emollient. In mascara, it is used as a film-forming component and conditioning agent. In hair care, it is used in growth serums and hot oil treatments for its conditioning and film-forming properties. In skincare, castor oil is used in cleansing balms (where its solubilising power for waxes and lipids enables facial cleansing), in serum formulations, and in barrier creams.

Utilisations pharmaceutiques et industrielles

Pharmaceutical-grade castor oil is used as a laxative (oral), as a solvent for injectable drugs (e.g., Cremophor EL, polyethoxylated castor oil for drug solubilisation), and as a topical carrier. Industrially, castor oil is the raw material for the production of sebacic acid, nylon-11, and polyurethane chemistry, and is used in lubricants, coatings, and plasticisers. Terracore Chemicals supplies castor oil in cosmetic and industrial grades.
