Description

Castor Oil, Acetylated is a chemically modified derivative of castor oil, where hydroxyl groups are esterified with acetyl groups. This modification significantly enhances its compatibility with hydrophobic systems and improves its stability, making it a versatile bio-based chemical intermediate. It is primarily used in the formulation of high-performance lubricants, plasticizers, and specialty coatings across various industrial sectors.

Application

• As a high-performance bio-based plasticizer for PVC, nitrocellulose, and other polymers, offering excellent low-temperature flexibility and migration resistance.
• As a key component in environmentally friendly lubricants and greases, providing superior viscosity-temperature characteristics and lubricity.
• In the production of specialty coatings and inks, where it acts as a modifying resin to enhance gloss, adhesion, and water resistance.
• As a cosmetic and personal care ingredient (e.g., in lipsticks, hair care products) for its emollient properties and skin feel.
• As a processing aid and internal lubricant in the manufacturing of engineering plastics and rubber compounds.
• In the formulation of wood treatment products and leather finishes to improve durability and surface properties.
