Description

Hpcs CAS NO 74056-94-3 is a high-purity hydroxypropyl cellulose derivative, a key cellulose ether valued for its excellent thickening, stabilizing, and film-forming properties. This compound is essential for formulators requiring precise rheology control and enhanced product performance in demanding applications. It is primarily utilized by manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking reliable, high-quality excipients and additives.

Application

• Pharmaceutical Formulations: As a binder, controlled-release matrix agent, and film-coating polymer in tablet and capsule manufacturing.
• Personal Care & Cosmetics: Used as a thickener, stabilizer, and suspending agent in shampoos, lotions, creams, and toothpaste.
• Food Industry: Functions as an emulsifier, stabilizer, and foam enhancer in various food products (subject to specific grade compliance).
• Paints & Coatings: Acts as a rheology modifier and thickener to improve application properties and stability of water-based paints.
• Adhesives and Construction Materials: Serves as a water-retention agent and thickener in cement-based products and adhesive formulations.
• Industrial Applications: Employed as a protective colloid and stabilizer in ceramic glazes and other specialty chemical processes.

Quality Control

Our Hpcs is manufactured under a strict quality management system to ensure batch-to-batch consistency and reliability. Quality is verified against relevant pharmacopeial standards (such as USP-NF, Ph. Eur., JP) where applicable, including tests for identification, assay, viscosity, and impurity profiles. A comprehensive Certificate of Analysis (COA) documenting purity, physicochemical properties, and compliance is provided with each shipment.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent moisture absorption, which can affect product performance.
