polyoxyethylene sorbitan monostearate were prepared using the standard mixing procedure set forth above and were compared as to their various viscosity values using a brookfield model lvt viscometer spindle 3 set at 12 rpm the percentages of polysorbate 60 are based on the total weight of the xanthan gum emulsifier composition and the viscosities were measured in centipoise units cps at four different times ______________________________________rhodigel fh testviscosities cps poly sorbate 60 1 min 2 min 4 min 8 min ______________________________________0 00 1400 2300 3500 4500 large large large large lumps lumps lumps lumps0 50 3700 4400 4600 4800 small small v small no lumps lumps lumps lumps0 75 3900 4500 4800 4800 small small no no lumps lumps lumps lumps1 00 4200 4500 4800 4800 small v small no no lumps lumps lumps lumps______________________________________ as shown by the respective viscosity values for the different xanthan gum polysorbate 60 compositions the greater the amount of emulsifier used the greater the viscosity of the gum composition with the greatest viscosity values realized at emulsifier amounts somewhere between 0 75 wt and 1 0 wt viscosity is also a function of the break up of the gum particles within the system with the absence of lumps creating the most viscous composition achievable as can be also seen from the chart there is a point between the concentrations of 0 75 wt and 1 0 wt of diminishing return i e regardless of how much more emulsifier is added to the composition the viscosity no longer increases referring now to fig1 the hydration rates of three xanthan gum emulsifier compositions of the present invention were compared with a pure xanthan gum composition with no emulsifier added to.
