Nope, I have not. I have HEC 5000 (Natrosol 250 M), Lotioncrafter’s HPC (which they don’t seem to offer any longer… so I have no specs ;( ) and MC (wallpaper paste LoL) sitting around on my shelves. I might give HPC a try, thanks for the tip!
The reason I haven’t tried HEC/HPC yet are, under others, the fact that they are ethoxylated/propoxylated, pharmaceutical CMC and HEC gels feel just awful and, maybe most importantly, I’ve totally forgot that I have them. But yes, they’re closer than polyacrylates to what I’m looking for.
However, I would guess that cetyl HEC might be suited best… any advice would be highly appreciated!
