Cold Pressed Grade Castor Oil (CPG) is a natural, unrefined oil extracted from castor seeds using a cold-pressing method, which preserves its nutrients and beneficial properties. This process involves minimal heat, ensuring that the oil retains its rich content of ricinoleic acid, vitamins, and fatty acids. CPG is known for its purity and high quality, making it ideal for cosmetic, therapeutic, and hair care applications. It is often used in skin care products, massage oils, and hair growth treatments, offering moisturizing, soothing, and anti-inflammatory benefits.
