Description

Polyglyceryl-2 Dioleate is a non-ionic, biodegradable surfactant derived from natural glycerin and oleic acid. This versatile compound is valued for its excellent emulsifying, solubilizing, and conditioning properties, making it a key ingredient in formulations requiring mildness and stability. It is primarily used by manufacturers in the personal care, cosmetics, and food industries to create stable emulsions and enhance product texture.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and sun care products.
• Skin conditioning agent and viscosity modifier in personal care formulations for a smooth, non-greasy feel.
• Food-grade emulsifier and stabilizer in certain food applications and food packaging coatings.
• Dispersing agent and lubricant in industrial applications, including metalworking fluids and textile processing.
• Key component in eco-friendly and "green" surfactant blends due to its natural origin and biodegradability.
• Used in pharmaceutical ointments and topical preparations as a non-irritating base.

Quality Control

Our Polyglyceryl-2 Dioleate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets consistent purity and performance specifications. Certificates of Analysis (COA) documenting key parameters such as acid value, saponification value, and fatty acid composition are available upon request. We support compliance with relevant frameworks for cosmetic (ISO 22716) and food-grade applications where specified.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage or after opening, consider storing under an inert atmosphere (e.g., nitrogen blanket) to maintain optimal quality. Keep away from strong oxidizing agents.
