Description

Product Description

Propylene glycol alginate, PGA for short, belongs to alginate esters. Part of the carboxyl groups of alginate are esterified by propylene glycol (more than 90%), and the remaining 10% of carboxyl groups are free or neutralized by alkali. Propylene glycol alginate is made from alginic acid extracted from natural seaweed through deep processing. The appearance is white or yellowish white powder, almost odorless or slightly aromatic, tasteless, hygroscopic, easily soluble in cold or warm water to form a viscous colloidal solution.
