Description

Poloxamer 105 Benzoate is a chemically modified, non-ionic surfactant derived from the polyoxyethylene-polyoxypropylene block copolymer family. This benzoate ester derivative is valued for its enhanced emulsifying, solubilizing, and stabilizing properties in complex formulations. It is primarily utilized in the pharmaceutical, cosmetic, and specialty chemical industries where precise control over solubility and interfacial activity is required.

Application

• Pharmaceutical Solubilizer & Emulsifier: Enhances the solubility and bioavailability of poorly water-soluble active pharmaceutical ingredients (APIs) in oral and topical formulations.
• Cosmetic & Personal Care Stabilizer: Acts as an effective emulsifier and stabilizer in creams, lotions, and ointments, improving texture and shelf-life.
• Industrial Dispersant: Used in agrochemicals, coatings, and pigment dispersions to improve wetting and prevent particle aggregation.
• Polymer & Plastic Additive: Serves as an antistatic agent, lubricant, or processing aid in polymer manufacturing.
• Research & Development: Employed as a critical excipient in novel drug delivery system research, including micelle and nanoparticle formation.

Quality Control

Our Poloxamer 105 Benzoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and performance consistency. While available in various grades, our standard product meets specifications suitable for industrial and research applications. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment.

Storage

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