Description

Poly[Oxy(Methyl-1,2-Ethanediyl)] is a high-purity polymer belonging to the poly(ethylene glycol) (PEG) family, widely recognized for its versatility as a solvent, plasticizer, and excipient. Its consistent molecular weight and low polydispersity are critical for ensuring predictable performance and compatibility in sensitive formulations. This product is essential for manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking reliable raw materials for drug delivery systems, cosmetic creams, and industrial lubricants.

Application

• Pharmaceutical Excipient: Used as a solubilizer, binder, and base for ointments, creams, and suppositories.
• Drug Delivery Systems: Serves as a key component in the formulation of controlled-release tablets and PEGylated protein therapeutics.
• Cosmetics & Personal Care: Acts as a humectant, thickener, and stabilizer in lotions, shampoos, and deodorants.
• Chemical Intermediate: Utilized in the synthesis of surfactants, lubricants, and plasticizers for various industrial applications.
• Laboratory Reagent: Employed in biochemical research for protein purification and cell fusion techniques.
• Food Additive: Functions as an emulsifier, texturizer, and moisture-retention agent in certain food products (subject to grade and local regulations).

Quality Control

Our Poly[Oxy(Methyl-1,2-Ethanediyl)] is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting parameters such as average molecular weight, hydroxyl value, and residue on ignition are available upon request. We can supply grades compliant with relevant pharmacopeial standards (e.g., USP-NF, EP, JP) for critical applications.

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); containers must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
