Description

Dipentadecyl Succinate is a high-purity diester compound, also known as bis(pentadecyl) succinate, with the CAS registry number 26720-10-5. It serves as a versatile and effective non-polar intermediate and specialty additive, prized for its excellent lubricity and hydrophobic properties. This chemical is essential for formulators and manufacturers in the lubricants, plastics, and personal care industries seeking to enhance product performance and stability.

Application

• Synthetic Lubricant Base Stock & Additive: Used as a high-performance base fluid or viscosity modifier in synthetic engine oils, compressor oils, and greases, offering superior thermal and oxidative stability.
• Plasticizer & Processing Aid: Acts as an internal lubricant and plasticizer in polymer processing (e.g., PVC, engineering plastics) to improve flexibility, reduce melt viscosity, and enhance mold release.
• Personal Care & Cosmetic Emollient: Functions as a non-greasy, spreading emollient and solvent in skincare formulations, lipsticks, and sunscreens, providing a smooth skin feel.
• Metalworking Fluid Component: Incorporated into cutting and grinding fluids as a friction-reducing agent and corrosion inhibitor.
• Textile & Fiber Lubricant: Applied as a spin finish or coning oil for synthetic fibers to reduce friction and static during high-speed textile manufacturing.
• Specialty Chemical Intermediate: Serves as a key building block in the synthesis of more complex esters, surfactants, and functional fluids.
