Description

Calcium Carrageenan is a refined, water-soluble polysaccharide derived from red seaweed, specifically the calcium salt of carrageenan. This compound is valued for its exceptional ability to form strong, rigid gels and to stabilize emulsions and suspensions in aqueous systems. It is a critical functional ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable texture modification and product stabilization.

Application

• Food Industry: Used as a gelling, thickening, and stabilizing agent in dairy products (e.g., flans, puddings, cheese), processed meats, water-based desserts, and vegetarian/vegan alternatives to gelatin.
• Pharmaceuticals: Employed as a binder and disintegrant in tablet formulations, and as a stabilizer and viscosity enhancer in suspensions, lotions, and controlled-release drug delivery systems.
• Personal Care & Cosmetics: Functions as a thickener and stabilizer in toothpastes, creams, lotions, and gels, providing a desirable texture and suspension of active ingredients.
• Technical Applications: Utilized in air freshener gels, pet food, and as a clarifying agent in brewing processes.
