Description

Alginic Acid Calcium Sodium Salt is a mixed salt derivative of alginic acid, a natural polysaccharide extracted from brown seaweed. This compound is valued for its unique gelling, thickening, and stabilizing properties, which are essential in creating controlled-release matrices and structured formulations. It serves as a critical functional ingredient for manufacturers in the pharmaceutical, food technology, and nutraceutical industries seeking natural and effective hydrocolloids.

Application

• Pharmaceutical Tablet Excipient: Used as a binder and disintegrant in solid dosage forms, particularly in controlled-release and chewable tablets.
• Food Stabilizer and Thickener: Imparts texture and stability to dairy products, desserts, sauces, and bakery fillings.
• Nutraceutical Encapsulation Agent: Forms protective matrices for the microencapsulation of vitamins, probiotics, and other sensitive active ingredients.
• Dental Impression Material: A key component in alginate-based dental impression materials due to its rapid gelation with calcium ions.
• Wound Care Formulations: Utilized in hydrogel dressings for its moisture-retention and film-forming capabilities.
• Industrial Applications: Acts as a thickener in textile printing pastes, paper coatings, and ceramic glazes.

Quality Control

Our Alginic Acid Calcium Sodium Salt is produced and tested under a strict quality management system. We offer grades compliant with relevant industry standards, including Food Chemical Codex (FCC) and pharmaceutical monographs where applicable. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, viscosity, and other critical parameters to ensure it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
