Description

Carboxymethyl Curdlan is a chemically modified, water-soluble derivative of the natural polysaccharide curdlan, known for its unique rheological and film-forming properties. This modification significantly enhances its solubility and functionality, making it a versatile hydrocolloid for advanced material science and life science applications. It is particularly valuable for industries requiring biocompatible thickeners, stabilizers, and encapsulation agents, such as pharmaceuticals, cosmetics, and food technology.

Application

• Pharmaceutical Excipient: Used as a binder, disintegrant, and controlled-release matrix in tablet and capsule formulations.
• Cosmetic Ingredient: Functions as a thickener, stabilizer, and film-forming agent in creams, lotions, and hair care products.
• Food Additive: Acts as a texture modifier, stabilizer, and dietary fiber supplement in various food products.
• Biomedical Materials: Employed in the fabrication of hydrogels, wound dressings, and drug delivery scaffolds due to its biocompatibility.
• Microencapsulation: Serves as a wall material for the encapsulation of flavors, fragrances, and active pharmaceutical ingredients (APIs).
• Industrial Applications: Used as a viscosity modifier and suspending agent in coatings, adhesives, and ceramic processing.

Quality Control

Our Carboxymethyl Curdlan is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as degree of substitution, viscosity, pH, and heavy metal content. Our quality commitment aligns with cGMP principles for pharmaceutical and food-grade 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance.
