Description

Zinc Diricinoleate is a metallic soap derived from ricinoleic acid, a key component of castor oil. This compound is valued for its excellent lubricating and stabilizing properties, making it a crucial functional additive in various high-performance formulations. It is primarily sought after by manufacturers in the cosmetics, personal care, and specialty polymer industries seeking to enhance product texture, stability, and performance.

Application

• Cosmetics & Personal Care: Acts as a high-efficiency viscosity modifier, opacifier, and emulsion stabilizer in creams, lotions, and deodorants.
• Pharmaceuticals: Used as a lubricant and release agent in tablet and capsule manufacturing.
• Polymers & Plastics: Functions as an internal lubricant and acid scavenger (stabilizer) in PVC and other polymer processing.
• Coatings & Inks: Serves as a dispersing agent and flow control additive to improve application properties and finish.
• Metalworking Fluids: Employed as a friction modifier and anti-wear additive in specialty lubricants.
• Adhesives & Sealants: Used to control rheology and improve the stability of adhesive formulations.
