Description

Lutrol (R) Op 2000 is a high-purity pharmaceutical-grade polyethylene glycol (PEG) polymer, identified by CAS No. 31394-71-5. This versatile excipient is critical for ensuring consistent drug delivery, bioavailability, and product stability in advanced formulations. It is an essential material for pharmaceutical manufacturers, cosmetic producers, and specialty chemical developers requiring a reliable and well-characterized polymer for solid dispersions, ointments, and controlled-release systems.

Application

• Pharmaceutical solid dispersions to enhance the solubility and dissolution rate of poorly water-soluble active ingredients.
• Base for ointments, creams, and topical preparations in dermatological products.
• Binder and plasticizer in tablet and capsule formulations.
• Matrix former for controlled-release and sustained-release drug delivery systems.
• Lubricant and processing aid in the manufacturing of solid dosage forms.
• Vehicle for suppositories and other semi-solid pharmaceutical preparations.
• Excipient in cosmetic formulations for creams, lotions, and personal care products.
• Component in specialty industrial applications requiring a high-molecular-weight, water-soluble polymer.

Quality Control

Our Lutrol Op 2000 is manufactured under strict quality management systems. It meets or exceeds relevant pharmacopoeial standards, including USP-NF and Ph. Eur. monographs for Macrogols. Each batch is supported by a comprehensive Certificate of Analysis (COA) verifying critical parameters such as identity, assay, hydroxyl value, and impurity profiles to ensure consistency and regulatory compliance for your applications.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
