Castor Oil Extract: Premium-Grade Ricinus Communis Product from Shaanxi Zhonghong Investment Technology

1. Product Overview

Castor oil extract (INCI: Ricinus Communis Seed Oil) is a multifunctional triglyceride derived from cold-pressed seeds of Ricinus communis. With a unique fatty acid profile dominated by ricinoleic acid (85–95%), this viscous, pale-yellow liquid serves as a cornerstone ingredient in pharmaceuticals, cosmetics, and industrial applications. Our pharmaceutical-grade castor oil exceeds USP/EP standards, achieving >99.5% purity via molecular distillation and supercritical CO₂ extraction.
