Propylene Glycol Alginate (E405)

Description

1. Propylene Glycol Alginate (E405) is a semi-synthetic, anionic polysaccharide derivative produced by esterifying alginic acid with propylene glycol and partially neutralizing to a stable salt form. It functions as a rheology modifier, stabilizer, emulsifier and film former across high-demand industrial processes. The product delivers predictable viscosity control, improved emulsion stability and enhanced surface properties, enabling consistent process performance and higher yield in formulations. For strategic buyers, E405 is a low-risk, high-value input that reduces formulation variability, simplifies production scale-up, and supports regulatory compliance in food-grade and industrial-grade applications.

3. Core Industrial Applications

• Food & Beverage: Stabilizer and emulsifier in acidified beverages, sauces, dressings, and gelled systems; improves mouthfeel and prevents phase separation in low-pH matrices. Outperforms many alternatives by maintaining viscosity under shear and acidic conditions while enabling cleaner label formulations when combined with natural gums.

• Pharmaceuticals & Nutraceuticals: Binder and film-former in oral suspensions and controlled-release matrices; provides consistent rheology for syringeable suspensions and uniformity in tablet coatings. Offers reproducible processability during scale-up.

• Personal Care & Cosmetics: Thickener and stabilizer in creams, gels, and emulsions; enhances sensory profile and stabilizes oil-in-water dispersions with reduced syneresis over time.

• Industrial Coatings & Adhesives: Rheology control and film-forming aid for waterborne coatings and adhesives; provides improved substrate wetting, leveling and reduced sagging.

• Paper & Textile Processing: Sizing and surface treatment to improve ink receptivity and print definition; enhances fiber bonding and dispersion stability.
  Commercial relevance: E405 delivers better acid-stability, predictable shear response, and scalable dissolution than many native alginates and synthetic thickeners, reducing batch rework and raw-material overhead.

4. Competitive Advantages
