PALE PRESSED GRADE CASTOR OIL (PPG)

Pale Pressed Grade Castor Oil (PPG) is a high-quality castor oil extracted through a gentle pressing process, resulting in a light-colored, pure oil with minimal odor. This grade of castor oil is refined to remove impurities while retaining its beneficial properties, such as moisturizing and anti-inflammatory effects. PPG is commonly used in cosmetics, personal care products, and pharmaceutical applications for its smooth texture and versatility. It is especially valued for its gentle and skin-friendly nature, making it suitable for formulations like lotions, creams, and hair care products.
