Description

Polyglyceryl-2 Isostearate is a non-ionic, multifunctional surfactant and emulsifier derived from natural glycerin and isostearic acid. This compound is valued for its excellent skin compatibility, effective emulsifying properties, and ability to enhance the texture and stability of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking high-performance, mild, and versatile raw materials.

Application

• Primary W/O (Water-in-Oil) emulsifier in creams, lotions, and sun care products.
• Key ingredient in makeup formulations, including foundations and lipsticks, for pigment dispersion and smooth application.
• Used as a co-emulsifier and stabilizer in pharmaceutical ointments and topical delivery systems.
• Functions as a viscosity modifier and texture enhancer in skin care serums and hair conditioners.
• Employed in food-grade applications as an emulsifier where regulatory compliance is required.
• Serves as a dispersing agent for inorganic powders and actives in cosmetic products.

Quality Control

Our Polyglyceryl-2 Isostearate is manufactured under strict quality management systems. Each batch is tested to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, saponification value, and heavy metal content are provided to guarantee consistency and compliance with cosmetic and relevant industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent rancidity. Keep away from strong oxidizing agents.
