Description

.Pi.-Carrageenan CAS NO 71078-00-7 is a refined, high-purity hydrocolloid derived from specific red seaweeds, valued for its unique gelling, thickening, and stabilizing properties. This versatile ingredient is critical for achieving precise texture, stability, and mouthfeel in a wide range of formulated products. It is an essential raw material for manufacturers in the food, pharmaceutical, and personal care industries seeking consistent performance and reliable supply.

Application

• Food Industry: Used as a gelling agent, thickener, and stabilizer in dairy products (e.g., flans, puddings, chocolate milk), processed meats, and water-based desserts.
• Pharmaceuticals: Employed as a binder and controlled-release matrix in tablet formulations, and as a stabilizer in suspensions and emulsions.
• Personal Care & Cosmetics: Functions as a viscosity modifier and stabilizer in toothpastes, creams, lotions, and gel-based products.
• Technical Applications: Serves as a thickening agent in air freshener gels, water-based paints, and ceramic glazes.
• Pet Food: Utilized as a binder and gelling agent in canned and wet pet food formulations to improve texture and moisture retention.
• Microbiology & Biotechnology: Acts as a gelling agent for solid culture media in microbiological laboratories.

Quality Control

Our .Pi.-Carrageenan is produced and tested under strict quality management systems to ensure it meets the high standards required by our global customers. We offer grades compliant with major international standards, including Food Chemicals Codex (FCC) and EU regulation (E 407). A comprehensive Certificate of Analysis (COA), detailing parameters such as viscosity, gel strength, purity, and microbiological limits, is provided with each batch to guarantee consistency and traceability.

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.
