Description

Polyglyceryl-2 Triisostearate is a non-ionic, lipophilic surfactant and emollient ester derived from polyglycerin and isostearic acid. This compound is highly valued for its excellent skin compatibility, stable emulsifying properties, and ability to provide a rich, non-greasy feel in formulations. It serves as a key functional ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to create stable, luxurious emulsions and skin-conditioning products.

Application

• Primary Emulsifier in water-in-oil (W/O) and oil-in-water (O/W) creams and lotions.
• Co-emulsifier and Stabilizer in cosmetic formulations to enhance texture and emulsion stability.
• Skin Conditioning Agent in facial treatments, body butters, and sun care products for a smooth, velvety afterfeel.
• Viscosity Modifier and thickener in anhydrous systems like makeup removers and cleansing oils.
• Lipophilic Surfactant in decorative cosmetics, including foundations and lipsticks.
• Base Ingredient in pharmaceutical ointments and topical delivery systems.
• Hair Care Conditioner in shampoos and conditioners to impart softness and manageability.

Quality Control

Our Polyglyceryl-2 Triisostearate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided and the material can be supplied to meet relevant cosmetic and personal care industry standards.

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 the material is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening for optimal long-term stability. Keep away from strong oxidizing agents.
