Combine phase A in the order listed with medium propeller mixing at 20-25°C. Mix until uniform (1-2 min). Blend phase C in a dry blender on medium speed until uniform. Check blend for streaking and re-blend if necessary until no streaking is observed. Add phase B to phase A and mix with a high shear mixer at medium speed until homogenous (2-3 min) at 20-25°C. Add phase D to batch, continue mixing with a high shear mixer at medium speed until batch is uniform. Combine phase E in order listed with medium prop mixing at 20-25°C. Mix until uniform (2-3 min).Slowly add Phase E to Phase ABCD with medium shear mixing, increase the shear speed as the solution starts to build viscosity. Mix for 3-4 minutes or until batch is homogeneous. Transfer to closed container.Notes:
