Propylene Glycol Alginate, an ester of alginic acid and propylene glycol, is a white to off-white powder derived from kelp, soluble in cold water to form viscous, acid-stable colloids with foam-stabilizing properties, typically with 50-85% esterification for food-grade applications per FDA inactive ingredient listings.

Propylene Glycol Alginate

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.

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.

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.
