Description

Fatty Acid, (C=6～24)-Branched 2,2-Dimethyl-1,3-Propanediyl Ester is a synthetic ester derived from a branched neopentyl glycol structure and a mixed chain-length fatty acid feedstock. This unique branched architecture provides exceptional oxidative stability and low-temperature performance, making it a valuable high-performance base fluid and chemical intermediate. It is primarily sought by formulators in the lubricants, plastics, and specialty chemicals industries seeking to enhance product longevity and performance under demanding conditions.

Application

• Synthetic Lubricants & Base Stocks: Used as a high-performance base oil or additive in synthetic engine oils, compressor oils, and gear oils due to its excellent thermal and oxidative stability.
• Polymer & Plastic Additives: Functions as a plasticizer or internal lubricant in PVC, engineering plastics, and elastomers to improve flexibility and processing.
• Metalworking Fluids: Serves as a key component in synthetic and semi-synthetic cutting, grinding, and drawing fluids, offering superior lubricity and resistance to rancidity.
• Cosmetic & Personal Care Esters: Employed as an emollient or skin-conditioning agent in high-end cosmetic formulations, valued for its non-greasy feel and stability.
• Specialty Chemical Intermediate: Acts as a building block for the synthesis of surfactants, corrosion inhibitors, and other functional chemicals.
• Hydraulic & Transmission Fluids: Formulated into high-tier industrial and automotive hydraulic fluids where extended fluid life and reliable performance are critical.

Quality Control

Our Fatty Acid, (C=6～24)-Branched 2,2-Dimethyl-1,3-Propanediyl Ester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as ester content, acid value, viscosity, and oxidation stability. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve quality. Keep away from strong oxidizing agents, strong acids, and strong bases.
