Description

Phenoxyacetylcellulose is a chemically modified cellulose ether derivative, valued for its unique combination of film-forming, thickening, and binding properties. This specialized polymer is engineered to offer enhanced solubility and stability profiles compared to standard cellulose ethers, making it a critical functional additive in advanced formulations. It is primarily utilized in the pharmaceutical, personal care, and specialty coatings industries where precise rheological control and biocompatibility are required.

Application

• Pharmaceutical Tablet Coating: Acts as a film-forming agent for controlled-release and enteric coatings, providing a uniform, stable barrier.
• Topical Gel & Ointment Formulations: Serves as a primary gelling and viscosity-modifying agent in dermatological and cosmetic products.
• Oral Suspension Stabilizer: Enhances the physical stability and palatability of suspension-based drug delivery systems.
• Specialty Adhesives and Binders: Used as a water-soluble binder in industrial applications and specialty adhesive formulations.
• Advanced Ceramic Processing: Functions as a temporary organic binder and rheology modifier in ceramic tape casting and extrusion.
• Food-Grade Film Production: Employed in the creation of edible films and protective coatings for food ingredients.

Quality Control

Every batch of Phenoxyacetylcellulose is manufactured and tested under a strict quality management system. We provide comprehensive quality assurance, including testing for degree of substitution, viscosity, purity, and residual solvents to meet exacting customer requirements. Certificates of Analysis (COA) documenting all critical parameters are available for each shipment. Our production adheres to cGMP principles where applicable, ensuring consistency and reliability for pharmaceutical and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to prevent moisture absorption, which can affect the product's physical properties and performance.
