Description

Alginic Acid Ammonium-Calcium Salt is a refined, mixed salt derivative of alginic acid, a natural polysaccharide extracted from brown seaweed. This compound is valued for its unique rheological properties, acting as a versatile thickener, stabilizer, and gelling agent in aqueous systems. It is essential for manufacturers in the pharmaceutical, food, and personal care industries seeking natural, multifunctional hydrocolloids.

Application

• Pharmaceutical Formulations: Used as a binder, disintegrant, and controlled-release matrix agent in tablet manufacturing.
• Food & Beverage Industry: Functions as a stabilizer and thickener in dairy products, sauces, and dessert gels, improving texture and mouthfeel.
• Cosmetics & Personal Care: Serves as a viscosity modifier and film-forming agent in creams, lotions, and hair care products.
• Technical & Industrial Applications: Employed in water treatment processes and as a component in ceramic glazes and welding rod coatings.
• Dental Impressions: A key material in alginate-based dental impression compounds due to its rapid gelation with calcium ions.
• Wound Care Dressings: Utilized in the production of alginate fiber dressings for their high absorbency and hemostatic properties.

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.
