Description

Cellulose, Hydrogen 1,2-Cyclohexanedicarboxylate, 2-Hydroxypropyl Methyl Ether is a chemically modified cellulose derivative, specifically a hydroxypropyl methylcellulose (HPMC) esterified with hydrogenated cyclohexanedicarboxylic acid. This unique modification imparts specific rheological and film-forming properties, making it a valuable functional polymer for advanced material science. It is primarily sought by formulators in the pharmaceutical, personal care, and specialty coatings industries seeking tailored viscosity control and release characteristics.

Application

• Pharmaceutical Excipient: Used as a controlled-release matrix former in tablet and capsule formulations, where its solubility profile can be engineered for delayed or sustained drug delivery.
• Personal Care & Cosmetics: Functions as a film-forming agent, thickener, and stabilizer in creams, lotions, and hair styling products, providing enhanced texture and long-lasting effects.
• Specialty Coatings: Serves as a binder and rheology modifier in water-based industrial and architectural coatings, improving application properties and film integrity.
• Food Industry (where compliant): Potential use as a thickener, emulsifier, or stabilizer in specialized food systems, subject to specific regulatory approval and grade availability.
• Adhesives and Sealants: Acts as a modifying agent to adjust viscosity, improve water retention, and enhance the performance profile of adhesive formulations.
• Ceramic and Construction Materials: Employed as a processing aid and water retention agent in tile adhesives, gypsum-based products, and other cementitious mixtures.

Quality Control

Our Cellulose, Hydrogen 1,2-Cyclohexanedicarboxylate, 2-Hydroxypropyl Methyl Ether is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in key parameters such as degree of substitution, viscosity, and purity. Certificates of Analysis (COA) documenting these results are available upon request. We can support compliance with relevant pharmacopeial standards (e.g., USP-NF, Ph. Eur.) for applicable grades.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent moisture uptake, which can affect physical properties.
