Description

Polyglyceryl-8 Oleate is a non-ionic, biodegradable surfactant derived from natural fatty acids and polyglycerol. This versatile compound is valued for its excellent emulsifying, solubilizing, and stabilizing properties in a wide range of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and food industries seeking effective, mild, and multifunctional ingredients.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and sunscreens, providing a smooth texture and enhancing skin feel.
• Food Industry: Used as an emulsifier and anti-spattering agent in margarines, spreads, and cooking oils, improving product consistency and performance.
• Pharmaceuticals: Serves as a solubilizer and bioavailability enhancer for poorly soluble active pharmaceutical ingredients (APIs) in topical and oral dosage forms.
• Industrial Applications: Functions as a lubricant, anti-static agent, and emulsifier in textile processing, metalworking fluids, and agricultural adjuvants.
• Household & I&I Cleaning: Employed in liquid soaps, detergents, and hard-surface cleaners for its surfactant and degreasing properties.

Quality Control

Our Polyglyceryl-8 Oleate is produced under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as acid value, saponification value, hydroxyl value, and residual matter are provided to guarantee consistent quality and traceability for your formulations.

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 product is easily oxidized; for long-term storage, consider using under an inert atmosphere (e.g., nitrogen blanket) to maintain optimal stability and prevent rancidity. Keep away from strong oxidizing agents.
