Description

Cellulose Microcrystalline Colloidal is a purified, partially depolymerized cellulose widely used as a versatile excipient and functional additive. Its value lies in its excellent binding, disintegrant, and suspension-stabilizing properties, making it a critical component in formulating stable and effective products. This material is essential for manufacturers in the pharmaceutical, food, nutraceutical, and cosmetic industries seeking reliable performance and compliance.

Application

• Pharmaceutical Tableting: Primarily used as a binder and disintegrant in direct compression and wet granulation processes for solid oral dosage forms.
• Food & Beverage Stabilization: Acts as a stabilizer, thickener, and anti-caking agent in various food products, sauces, and dairy alternatives.
• Nutraceutical & Vitamin Formulations: Serves as a key excipient in vitamin tablets, mineral supplements, and herbal extract capsules.
• Cosmetics & Personal Care: Used as a viscosity modifier, suspension agent, and texture enhancer in creams, lotions, and toothpaste.
• Suspension & Emulsion Stabilizer: Provides long-term stability in liquid formulations, preventing settling and separation.
• Industrial Applications: Functions as a binder in ceramics, catalysts, and other specialty chemical processes.

Quality Control

Our Cellulose Microcrystalline Colloidal is manufactured under strict quality systems. We offer grades that can meet or exceed relevant pharmacopeial standards such as USP-NF, Ph. Eur., and JP, as well as food-grade specifications (FCC). Every batch undergoes rigorous testing for identity, purity, particle size, and functional performance. Certificates of Analysis (COA) documenting full compliance are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 flow and compaction properties.
