ABSTRACT OF THE DISCLOSURE Alginic acid which has been neutralized to the ex- tent of about 0.2 - 17 mole percent, preferably about 3 - 12 mole percent, and has a solids content of from about 20 to about 80 weight percent, is reacted with propylene oxide at a temperature of from about 60°C. to about 140°C., at a pressure sufficient to maintain the propylene glycol in liquid phase. The reaction is complete when a 2 percent (weight) solution of the propylene glycol alginate has a pH of from about 3.4 to about 4.9. The reaction is conducted in the substantial absence of any gas other than that present due to the vapor pressure of the reactants.
