Description

Carrageenan, Ammonium Salt is a refined, high-purity ammonium derivative of the natural polysaccharide carrageenan, widely recognized for its superior gelling, thickening, and stabilizing properties. This compound is essential for formulators seeking a clean-label, highly functional hydrocolloid with excellent synergy in complex aqueous systems. It is a critical ingredient for manufacturers in the food, pharmaceutical, and personal care industries, where consistent performance and regulatory compliance are paramount.

Application

• Food & Beverage: As a gelling agent, thickener, and stabilizer in dairy products (e.g., puddings, flans), processed meats, plant-based alternatives, and dessert gels.
• Pharmaceuticals: Used as a suspending agent, viscosity enhancer, and controlled-release matrix in liquid formulations, topical gels, and tablet coatings.
• Personal Care & Cosmetics: Functions as a film-former, thickener, and stabilizer in toothpaste, creams, lotions, and hair gels to improve texture and stability.
• Industrial Applications: Employed as a binder, thickener, or suspending agent in water-based paints, adhesives, and ceramic glazes.
• Microbiology & Biotechnology: Serves as a gelling agent for solid culture media in microbiological laboratories.

Quality Control

Our Carrageenan, Ammonium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for identity, purity, and functionality. We can supply material compliant with relevant standards such as FCC (Food Chemicals Codex) and pharmaceutical-grade requirements. A comprehensive Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistency.

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 absorption of atmospheric moisture, which can affect performance.
