Description

Diethylene Glycol Diisononanoate is a high-purity, synthetic ester derived from diethylene glycol and isononanoic acid. This versatile compound serves as a premium emollient and solvent, prized for its excellent skin feel, low viscosity, and compatibility with a wide range of cosmetic and industrial formulations. It is an essential ingredient for manufacturers in the personal care, coatings, and specialty chemical industries seeking high-performance, low-odor raw materials.

Application

• Cosmetic & Personal Care Formulations: Acts as a superior emollient and solvent in sunscreens, creams, lotions, and makeup products, providing a non-greasy, silky skin feel.
• Plasticizer for Polymers: Used as a specialty plasticizer to improve the flexibility and processability of various polymer resins.
• Lubricant & Metalworking Fluids: Serves as a base or additive in synthetic lubricants and metalworking fluids due to its thermal stability and lubricity.
• Industrial Coatings & Inks: Functions as a coalescing agent and solvent in high-performance coatings, printing inks, and adhesives.
• Chemical Intermediate: Utilized in the synthesis of more complex esters and specialty chemicals.
