Description

Potassium Carrageenan is a potassium salt of carrageenan, a high molecular weight sulfated polysaccharide extracted from red seaweed. This versatile hydrocolloid is prized for its exceptional ability to form strong, elastic gels and provide viscosity, stabilization, and texture modification in aqueous systems. It is a critical functional ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking clean-label, plant-based solutions.

Application

• Food Industry: Used as a gelling, thickening, and stabilizing agent in dairy products (e.g., flans, puddings, cream), processed meats, water-based desserts, and plant-based alternatives.
• Pharmaceuticals: Employed as a binder and disintegrant in tablet formulations, and as a gelling/viscosity agent in controlled-release drug delivery systems and topical preparations.
• Personal Care & Cosmetics: Functions as a thickener, stabilizer, and film-forming agent in toothpastes, creams, lotions, and gels, providing a smooth texture and suspension of particulates.
• Technical Applications: Utilized in air freshener gels, water-based adhesives, and as a viscosity modifier in various industrial formulations.
• Pet Food: Acts as a gelling agent to create consistency in canned and semi-moist pet food products.

Quality Control

Our Potassium Carrageenan is manufactured and tested to meet stringent quality standards appropriate for its intended application grade (Food, Pharmaceutical, Technical). Quality assurance protocols include testing for key parameters such as gel strength, viscosity, purity, and microbiological safety. We provide full traceability and Certificates of Analysis (COA) are available upon request to ensure compliance with your specifications and relevant standards like FCC, USP/NF, or EU directives.

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.
