Description

Glyceryl Dioleate is a non-ionic, biodegradable surfactant and emulsifier derived from oleic acid and glycerol. This versatile chemical intermediate is valued for its excellent lubricity, softening properties, and ability to form stable emulsions in a variety of systems. It is essential for formulators and manufacturers in the personal care, cosmetics, pharmaceutical, and food processing industries seeking effective, multifunctional ingredients.

Application

• Cosmetics & Personal Care: Acts as a skin-conditioning agent, emollient, and co-emulsifier in creams, lotions, and makeup products.
• Pharmaceuticals: Used as a solubilizer, bioavailability enhancer, and component in topical ointments and transdermal delivery systems.
• Food Industry: Functions as an emulsifier and dispersing agent in food-grade lubricants and certain food additive formulations.
• Industrial Lubricants & Metalworking: Provides lubricity and anti-wear properties in synthetic lubricants and metal processing fluids.
• Textile & Leather Processing: Serves as a softening agent and lubricant in fiber treatments and leather finishing.
• Plastics & Polymers: Employed as an internal lubricant and anti-static agent in polymer processing.

Quality Control

Our Glyceryl Dioleate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters including assay, acid value, saponification value, and peroxide value. Our quality commitment supports compliance with relevant standards for industrial, cosmetic, and food-contact applications where specified.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This material is easily oxidized; for long-term storage or opened containers, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from strong oxidizing agents.
