  Perfume addition in dishwash formulation- viscosity drop

  Posted by ganeshjanakan on July 29, 2020 at 4:34 pm

  I am making manual dishwash liquid as follows for a 1000 ml batch
  8% labsa nuetralised by caustic soda
  20% of SLES(28%), 12g salt, perfume 1ml, color, 1 g citric acid
  After addition of salt the thickening is excellent. On addition of perfume the viscosity crashes by 50%. I tried various perfumes and the result is that the viscosity crashing varies.between 25% to 60%.

  Your fragrance likely has a nonylphenol ethoxylate as solvent-carrier. Crashes viscosity all the time.
