Description

Polyglyceryl-3 Caprate is a non-ionic, biodegradable surfactant derived from renewable resources. This versatile compound is valued for its excellent emulsifying, solubilizing, and conditioning properties, making it a key ingredient in high-performance formulations. It is primarily used by manufacturers in the personal care, cosmetics, and food industries seeking mild, effective, and sustainable ingredients.

Application

• Personal Care & Cosmetics: Acts as a primary or co-emulsifier in creams, lotions, and sunscreens; enhances the solubility of active ingredients and fragrances; provides a smooth, non-greasy skin feel.
• Food Industry: Used as an emulsifier and stabilizer in various food products, contributing to texture and shelf-life stability.
• Pharmaceuticals: Serves as a solubilizer and bioavailability enhancer for poorly soluble active pharmaceutical ingredients (APIs) in topical and oral formulations.
• Industrial Applications: Functions as a wetting agent, dispersant, or emulsifier in agrochemicals, lubricants, and cleaning formulations.

Quality Control

Our Polyglyceryl-3 Caprate is produced under a strict quality management system. Each batch is tested to ensure it meets specifications for identity, purity, and performance. We can provide material compliant with relevant standards such as Food Grade (FCC) and COSMOS/ECOCERT for natural cosmetics. A comprehensive Certificate of Analysis (COA) is available for every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). As this material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain optimal quality. Keep away from strong oxidizing agents.
