Description

Iotacarrageenan is a high-purity, sulfated polysaccharide derived from specific red seaweed species. This versatile hydrocolloid is valued for its exceptional ability to form strong, elastic gels and provide superior stabilization in complex formulations. It is a critical functional ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable texture modification and product consistency.

Application

• Food Industry: As a gelling, thickening, and stabilizing agent in dairy products (yogurts, puddings, flans), confectionery, processed meats, and plant-based alternatives.
• Pharmaceuticals: Used in controlled-release drug delivery systems, as a binder in tablet formulations, and to stabilize emulsions and suspensions.
• Personal Care & Cosmetics: Provides viscosity and gel structure in toothpastes, creams, lotions, and hair gels, enhancing product texture and stability.
• Biotechnology & Microbiology: Serves as a gelling agent for solid culture media in microbiology laboratories.
• Technical Applications: Employed in water-based paints, adhesives, and ceramic glazes as a rheology modifier and suspension aid.

Quality Control

Our Iotacarrageenan is produced under strict quality management systems. We offer grades compliant with major international standards including FCC (Food Chemicals Codex) and Food Grade specifications. Every batch is tested for key parameters such as gel strength, viscosity, and microbiological purity. Comprehensive Certificates of Analysis (COA) are available upon request to ensure traceability and compliance for your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled 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.
