Description

Oxirane, Methyl-, Polymer With Oxirane, Succinate, Disodium Salt is a high-purity, water-soluble polymer derivative of propylene oxide and ethylene oxide, terminated with a disodium succinate group. This specialized chemical is valued for its excellent surfactant and dispersant properties, making it a critical performance additive in demanding industrial formulations. It is primarily sought after by manufacturers in the personal care, pharmaceutical, and specialty chemical industries for its ability to modify rheology, enhance stability, and improve compatibility in aqueous systems.

Application

• Personal Care & Cosmetics: Acts as a gentle surfactant, emulsifier, and viscosity modifier in shampoos, body washes, and skin creams.
• Pharmaceutical Formulations: Used as an excipient in topical gels, creams, and ointments to enhance drug solubility and delivery.
• Industrial Dispersants: Effective dispersing agent for pigments, fillers, and insoluble particles in water-based coatings and inks.
• Textile Processing: Serves as a leveling agent and dye dispersant to ensure uniform color application.
• Detergent & Cleaning Products: Functions as a co-surfactant and anti-redeposition agent in liquid and powder detergents.
• Agricultural Adjuvants: Enhances the spreading and sticking properties of pesticide and herbicide formulations.

Quality Control

Our Oxirane, Methyl-, Polymer With Oxirane, Succinate, Disodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, moisture content, and heavy metals are available upon request to support your quality assurance protocols.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
