Description

Propyleneglycol Alginate (CAS NO 9005-37-2) is a high-purity, chemically modified alginate derivative valued for its exceptional stabilizing and thickening properties. This versatile compound is crucial for creating stable, high-quality emulsions and suspensions in demanding formulations. It is an essential ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable texture control and product consistency.

Application

• Food & Beverage Industry: Acts as a stabilizer, thickener, and emulsifier in salad dressings, sauces, dairy products (e.g., ice cream, yogurt), fruit drinks, and beer to prevent foam collapse and improve mouthfeel.
• Pharmaceutical Formulations: Used as a suspending agent, viscosity enhancer, and stabilizer in liquid oral suspensions, topical gels, and controlled-release drug delivery systems.
• Cosmetics & Personal Care: Serves as a film-forming agent, thickener, and stabilizer in lotions, creams, toothpastes, and hair care products to provide desirable texture and stability.
• Industrial Applications: Employed as a binder, thickener, or stabilizer in ceramic glazes, water-based paints, and textile printing pastes.
• Dental Impressions: Used in some alginate-based dental impression materials for its modified setting and elastic properties.
