  Sediments at the bottom of the bottle

  Posted by Soona on April 20, 2021 at 1:18 pm

  ;SLES 10%
    Coco betaine8%
   Salicylic acid. 1%
  Glycerin.  10%
   Propylene glycol. 2%
  EDTA.    0.1%
   Xanthan.       0.5%
   PQ7 2%
  Liquid pearlizer.    0.5%
  DW.   up to100
  
  Then NaOH and NaCl for pH and viscosity adjustment, what is happening? Why I am having sediments ? Any suggestions for the cause & how to solve this?????

  Salicylic acid would be my guess. Not much there to solubilize it, plus that PQ10 makes salicylic acid that much harder to maintain solution.

  I used to formulate without PQ7 , and I never faced such a problem, so any suggestions to save my batch ?
