Description

Ammonium Alginate is the ammonium salt of alginic acid, a natural polysaccharide derived from brown seaweed. This versatile hydrocolloid is prized for its ability to form stable, high-viscosity solutions and gels, making it an essential functional ingredient across multiple industries. Key sectors that rely on its unique properties include the pharmaceutical, food, textile, and personal care industries, where it serves as a thickener, stabilizer, and film-forming agent.

Application

• Pharmaceutical Formulations: Used as a binder, disintegrant, and controlled-release matrix in tablet manufacturing, and as a thickening agent in topical gels and wound dressings.
• Food Industry: Functions as a stabilizer, thickener, and gelling agent in products like sauces, dairy desserts, and fruit fillings, improving texture and mouthfeel.
• Textile Printing: Serves as an effective thickener for reactive dye pastes, providing sharp print definition and excellent wash-off properties.
• Personal Care & Cosmetics: Incorporated into creams, lotions, and masks as a natural viscosity modifier and film-forming agent for skin conditioning.
• Biotechnology & Research: Utilized for cell encapsulation, immobilization of enzymes, and as a scaffold material in tissue engineering due to its biocompatibility.
• Industrial Applications: Acts as a binder in ceramic glazes, welding rod coatings, and water-based paints.

Quality Control

Our Ammonium Alginate is manufactured under a strict quality management system. Each batch is tested to ensure it meets relevant specifications for its intended application, whether for food (FCC), pharmaceutical (USP/EP), or technical use. A comprehensive Certificate of Analysis (COA) documenting purity, viscosity, and other critical parameters is provided with every shipment to guarantee traceability and compliance.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
