Propylene glycol alginate (PGA) is an emulsifier, stabilizer, and thickener used in food products. It is a food additive with E number E405. Chemically, propylene glycol alginate is an ester of alginic acid, which is derived from kelp. Some of the carboxyl groups are esterified with propylene glycol, some are neutralized with an appropriate alkali, and some remain free.[1]
