Description

.Xi.-Carrageenan CAS NO 70431-33-3 is a high-purity, refined hydrocolloid derived from specific red seaweeds, belonging to the iota (ι) carrageenan family. This versatile polysaccharide is prized for its exceptional gelling, thickening, and stabilizing properties, forming soft, elastic gels in the presence of calcium ions. It is an essential functional ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking superior texture control and product stability. Its unique rheological profile makes it ideal for applications requiring a smooth, creamy mouthfeel and excellent freeze-thaw stability.

Application

• Food Industry: As a gelling agent and stabilizer in dairy products (yogurt, cream, flan), dessert gels, meat products (for water binding and texture improvement), and plant-based alternatives.
• Pharmaceuticals: Used as a binder and disintegrant in tablet formulations, and as a gelling/thickening 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 hair gels to provide desirable viscosity and texture.
• Biotechnology & Microbiology: Employed as a gelling agent in culture media for the immobilization of cells and enzymes.
• Pet Food: Used as a binder and gelling agent in canned and semi-moist pet foods to improve texture and palatability.
• Air Freshener Gels: Serves as the gelling matrix in solid-form air fresheners for controlled fragrance release.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a 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. Keep away from strong oxidizing agents.
