Description

Carboxymethyl β-Glucan CAS NO 133875-94-2 is a chemically modified derivative of β-glucan, a naturally occurring polysaccharide, designed to enhance solubility and bioactivity. This modification is critical for improving the functional performance and stability of the compound in advanced formulations. It is an essential ingredient for industries requiring high-performance, water-soluble biopolymers with immunomodulatory and film-forming properties.

Application

• Pharmaceuticals & Nutraceuticals: Used as an active pharmaceutical ingredient (API) or excipient in immune-support supplements, wound healing formulations, and drug delivery systems.
• Cosmetics & Personal Care: Serves as a high-performance moisturizing agent, film-former, and skin barrier enhancer in creams, serums, and lotions.
• Food & Beverage: Functions as a soluble dietary fiber, thickener, and stabilizer in functional foods and beverages.
• Biomedical Research: Employed as a standard or reagent in immunological studies and material science for hydrogel development.
• Industrial Applications: Utilized in specialty coatings, adhesives, and as a biodegradable polymer component.

Quality Control

Our Carboxymethyl β-Glucan is produced under a rigorous quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and functionality. Certificates of Analysis (COA) documenting key parameters such as degree of substitution, carbohydrate content, and heavy metals are available upon request. We adhere to cGMP principles where applicable to support pharmaceutical and nutraceutical 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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and flow properties.
