Description

Phosphogalactomannan is a chemically modified polysaccharide derived from galactomannan, primarily sourced from guar or locust bean gum, through phosphorylation. This modification introduces phosphate groups, significantly enhancing its functionality as a versatile hydrocolloid with improved ionic interaction and stability. It is a critical ingredient for formulators in the food, pharmaceutical, and personal care industries seeking advanced rheology modifiers, stabilizers, and encapsulation agents. Its unique properties make it valuable for creating controlled-release systems, stabilizing emulsions, and modifying texture in complex formulations.

Application

• Food Industry: Used as a thickener, stabilizer, and texture modifier in sauces, dressings, dairy products, and low-fat formulations to improve mouthfeel and prevent syneresis.
• Pharmaceuticals: Serves as an excipient in controlled-release tablet matrices and as a stabilizer in suspensions and emulsions, leveraging its modified solubility and gelation properties.
• Nutraceuticals & Supplements: Employed in the microencapsulation of sensitive active ingredients like vitamins, probiotics, and oils to enhance stability and bioavailability.
• Personal Care & Cosmetics: Functions as a film-forming agent, viscosity enhancer, and stabilizer in creams, lotions, and hair care products.
• Industrial Applications: Acts as a binder, rheology modifier, or flocculant in specialty coatings, adhesives, and water treatment processes.
• Research & Development: Utilized in biochemical and biomedical research for studying carbohydrate-protein interactions and developing novel biomaterials.

Quality Control

Our Phosphogalactomannan is produced under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for parameters such as degree of substitution, viscosity, purity, and microbiological limits. Certificates of Analysis (COA) documenting these results are provided with every shipment. We can supply grades suitable for various applications, including those aligning with food-grade (FCC) and pharmaceutical excipient standards.

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 material is hygroscopic (moisture-sensitive); keep the container tightly sealed to prevent absorption of atmospheric moisture.
