Hey,
Sometimes I use PEG-150 distearate as a thickener in some formulations, but I notice there is no increase in the viscosity (even using high concentrations). I noticed that this happens when I use some non-ionic (e.g. decyl glucoside) and non-sulfated anionic surfactants (e.g. disodium cocoyl glutamate).
Does anyone noticed it too? Why does this happen?
Thanks in advance
