Hydroxy ethyl cellulose: HEC

we are developing a liquid soap (oil saponified with potash) based on olive oil, the composition of which is as follows:
% Dry matter: 20% + / - 1% with 55% olive oil and 45% coconut oil.
We want to viscose this formula with hydroxyethyl cellulose "HEC".
I find it difficult to choose the correct procedure for dissolving HEC in liquid soap. My question is the following: What is the correct method to disperse HEC in liquid soap?

    Will not work.  HEC will crash and gel out of solution, as will most of the cellulosics, within an alkaline soap system like that. Klucel (hydroxypropyl- ) or cellulose gum (sodium carboxymethyl-) would be first ones to try. As for method: always disperse the resin into water first and allow to hydrate 100% before adding any other ingredient.
  • After making soap it can't be dissolve 
    First dissolve it in water and pour it into oils and then pour caustic after that it can't separate

    Thank you Mr Farrukh
    Our manufacturing process is a semi-hot saponification. the HEC does not degrade under the effect of temperature?
