0.30 g/100 of the gel

Dissolve disodium EDTA in deionized water. Disperse Carbopol Ultrez 21 Polymer on the surface of deionized water. When the polymer is fully wetted, mix batch (200-300 rpm) and slowly add Glucam E-20 humectant and butylene glycol. Mix until uniform.  Neutralize the batch with phase B. Mix until uniform.  Decrease the mixing speed to 100-200 rpm. Make a 1% TS solution of sodium hyaluronate. Sequentially add the components of phase C to batch. Mix until uniform.  Continue mixing and add phase D ingredients.  Mix until uniform. Slowly add the beads into the gel (0.30g : 100g gel) through slow agitation (50 rpm).

Appearance: Translucent low viscosity gel with suspended beads; pH: 5.5-6.0; Viscosity (mPa·s) Brookfield DV-II+ Pro @ 20 rpm, 25°C, #3 spindle, measured at 24 hours:1,400-1,600; Yield Value (dyn/cm²) 80-130; PC 801 Colorimeter – (Sybron Brinkman): 80-85; Recommended Packaging: Clear pump bottle     (with UV protection); Stability: Passed 3 months @ 45°C and 25°C, 5 cycles freeze/thaw.
