The viscosity stability of xanthan solutions is crucial to petroleum recovery processes. The effects of oxygen concentration, pH, and temperature on viscosity during aging up to 6 months were studied.

Xanthan shows a well-known conformational transition in salt free solution at slightly elevated temperature, upon charging. Recently, a second transition was reported at higher temperature, when potentiometric results were analyzed using a Henderson-Hasselbalch representation of the titration curves
