Description

Steareth-100/PEG-136/HDI Copolymer is a high-performance, non-ionic polymeric surfactant and emulsifier formed from the reaction of steareth-100, polyethylene glycol, and hexamethylene diisocyanate. This unique copolymer is engineered to provide exceptional stability, thickening, and emulsifying properties in demanding formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to create stable, high-quality emulsions and delivery systems.

Application

• Primary emulsifier and stabilizer in high-viscosity creams, lotions, and ointments for personal care.
• Key rheology modifier and thickener in hair styling gels, conditioners, and sunscreen formulations.
• Stabilizing agent for oil-in-water (O/W) emulsions in cosmetic and topical pharmaceutical products.
• Used as a dispersing aid for pigments and actives in color cosmetics and makeup products.
• Component in controlled-release drug delivery systems and transdermal patches.
• Emulsifier for industrial and institutional cleaning product formulations requiring stability.

Quality Control

Our Steareth-100/PEG-136/HDI Copolymer is manufactured under a rigorous quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. While suitable for cosmetic and topical pharmaceutical applications, specifications can be aligned with relevant guidelines. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can affect performance.
