Viscosity decrease with increasing temperature can be explained using Arrhenius law. What happens when viscosity increases with temperature increase?

I measured the viscosity versus shear rate curves of surfactant solutions (non-ionic) and found pseudoplastic nature, which is normal. However, interestingly I found the viscosity to increase very...
