Description

Magnesium Alginate is the magnesium salt of alginic acid, a natural polysaccharide derived from brown seaweed. This compound is valued for its excellent gelling, thickening, and stabilizing properties, particularly in formulations requiring controlled viscosity and texture. It serves as a key functional ingredient for manufacturers in the pharmaceutical, food, and personal care industries seeking natural and effective hydrocolloids.

Application

• Pharmaceutical Formulations: Used as a binder, disintegrant, and sustained-release matrix in tablet manufacturing, and as a thickening agent in liquid suspensions and gels.
• Food & Beverage Industry: Functions as a stabilizer, thickener, and gelling agent in products like dairy alternatives, desserts, sauces, and low-calorie foods.
• Nutraceuticals & Dietary Supplements: Employed in capsule formulations and as a fiber source in supplement products.
• Cosmetics & Personal Care: Acts as a viscosity modifier and stabilizer in creams, lotions, toothpastes, and other topical formulations.
• Wound Care & Medical Devices: Utilized in the production of advanced wound dressings and hemostatic agents due to its absorbent and gel-forming capabilities.
• Technical & Industrial Applications: Serves as a thickener in water-based paints, adhesives, and ceramic glazes.

Quality Control

Our Magnesium Alginate 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-grade specifications where applicable. Every batch is accompanied by a comprehensive Certificate of Analysis (COA) to ensure traceability and confirm critical parameters such as purity, viscosity, and heavy metal content.

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 to prevent absorption of atmospheric moisture, which can affect product performance.
