Description

.Mu.-Carrageenan is a specific, high-purity fraction of carrageenan, a family of linear sulfated polysaccharides extracted from red seaweed. This compound is valued for its unique gelling, thickening, and stabilizing properties, which are critical for achieving precise texture and stability in sensitive formulations. It is essential for manufacturers in the pharmaceutical, food science, and personal care industries who require a consistent and reliable hydrocolloid for advanced product development.

Application

• Pharmaceutical Formulations: Used as a gelling, suspending, and stabilizing agent in medicated gels, controlled-release tablets, and topical creams.
• Food & Beverage Industry: Functions as a thickener, stabilizer, and gelling agent in dairy products (e.g., puddings, flans), dessert gels, and plant-based meat alternatives.
• Microbiological & Diagnostic Media: Serves as a solidifying agent in the preparation of culture media for laboratory and clinical microbiology.
• Personal Care & Cosmetics: Employed to modify viscosity and provide a smooth texture in toothpastes, lotions, and hydrogel-based cosmetic products.
• Biotechnology & Tissue Engineering: Investigated for use as a hydrogel matrix for cell encapsulation, 3D bioprinting, and drug delivery systems.
• Pet Food & Animal Feed: Acts as a binder and texture enhancer in wet pet food and specialized nutritional gels.

Quality Control

Our .Mu.-Carrageenan is produced and tested under a stringent quality management system. We offer grades suitable for various applications, with specifications aligned to industry standards such as FCC (Food Chemicals Codex) and pharmaceutical guidelines. Every batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters like assay, viscosity, sulfate content, and microbiological purity, ensuring traceability and consistency for your critical processes.

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 opening to prevent caking and degradation due to moisture absorption.
