Description

Propyleneglycolalginate is a high-purity, chemically modified alginate derivative widely used as a stabilizer and thickener. Its primary value lies in its ability to form stable, viscous solutions and gels in both acidic and neutral conditions, where other hydrocolloids may fail. This makes it an essential functional ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable texture control and emulsion stability.

Application

• Food & Beverage Industry: Acts as a stabilizer, thickener, and emulsifier in salad dressings, sauces, fruit drinks, beer foam, and dairy products like yogurt and ice cream.
• Pharmaceutical Formulations: Used as a binder, disintegrant, and controlled-release matrix agent in tablet manufacturing and liquid suspensions.
• Cosmetics & Personal Care: Provides viscosity and stabilization in lotions, creams, toothpastes, and hair care products.
• Technical Applications: Employed in paper coating, textile printing, and ceramic glazes as a rheology modifier and water-retention agent.

Quality Control

Our Propyleneglycolalginate is manufactured under strict quality management systems. Each batch is tested to ensure it meets relevant specifications for food grade (FCC, EU E405) or pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, viscosity, and other critical parameters is provided with every shipment to guarantee consistent quality 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 moisture absorption and caking.
