Propylene Glycol Alginate (CAS 9005-37-2) is an ester of alginic acid and propylene glycol, supplied as a white to off-white powder derived from kelp, typically 50-85% esterified for food-grade use, and it forms viscous, acid-stable colloids used as a foam enhancer in beer and an emulsion stabilizer in acidic dressings.

Applications
Used as foam enhancers in beer production; in acidic dressings for emulsion stability; in pharma suspensions for viscosity control; in fruit purees for texture retention; and in dairy analogs for creaminess in plant-based food processing.
Safety & Risks
GRAS with low allergen potential; high concentrations may cause mild laxative effects. Dust explosion hazard in powdery states; ensure grounding equipment and use food-safe PPE to adhere to hygiene standards during blending.
Packaging
Bagged in 20 kg multi-layer kraft sacks with food-contact liners. Stack in clean, dry food storage facilities with rotation protocols for shelf-life management.
