  HEC

  Posted by Tyss on September 1, 2021 at 5:23 pm

  Dear all
  I used as viscosity agent for my liquid soap (55% olive oil and 45% copra) at 20% dry matter modified hydroxyethyl cellulose of the order of 1% I found a viscosity of the order of  759 CP at 20 ° C which is not normal
  I passed the sample to centrifugation test for 15 minutes at 30 rpm per minute, a deposit at the bottom of the tube appears.
  the same phenomenon appears in the sample placed  at 50 ° C for 1 day
   I did not understand what happened
   I need your help 
  Best regards

  It sounds like you didn’t completely dissolve the HEC in water.
