For businesses operating in the chemical, pharmaceutical, cosmetic, and agricultural sectors, understanding the precise specifications of raw materials is fundamental to successful product development and consistent quality. Carboxymethyl Chitosan (CMC) is a prime example of a versatile biopolymer whose performance is heavily dictated by its key parameters. For procurement specialists and R&D scientists aiming to buy Carboxymethyl Chitosan, a thorough understanding of these specifications is crucial for making informed purchasing decisions.
The foundation of Carboxymethyl Chitosan's utility lies in its chemical structure, derived from chitosan. Critical specifications to consider when purchasing CMC include the Degree of Carboxylation (often denoted as Degree of Substitution, or DS) and the Deacetylation Degree (DAC). A higher DS, typically ≥80%, indicates a greater degree of carboxymethyl modification, which directly impacts water solubility and functionality. Similarly, a high DAC degree (often ≥90%) reflects the quality of the initial chitosan precursor and influences CMC's residual cationic properties and biological interactions. We, as a leading manufacturer, provide detailed COAs confirming these essential parameters for our Carboxymethyl Chitosan Powder.
Viscosity is another vital specification, particularly for applications where rheological properties are important, such as in cosmetics and some pharmaceutical formulations. The viscosity of CMC solutions can range widely and is dependent on factors like molecular weight and concentration. Buyers should specify their viscosity requirements based on their intended application. For instance, a product with a viscosity range of 50-800 mPa.s might be suitable for various uses, but niche applications may demand tighter controls. This parameter is crucial when you need to buy Carboxymethyl Chitosan for specific functional roles.
Appearance and purity are also key indicators of quality. Off-white to faint yellow powder is typical for Carboxymethyl Chitosan. Impurity levels, such as moisture content (usually ≤10%), ash content (≤1.5%), and limits on heavy metals (e.g., Lead ≤0.5ppm), are critical for compliance, especially in pharmaceutical and cosmetic applications. Particle size and bulk density are also important for handling and formulation. As a dedicated supplier and manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. ensures that our Carboxymethyl Chitosan Powder meets stringent purity standards, offering reliable quality for diverse industrial needs.
