Replacement for Xanthan Gum (low foam) - CMC, HEC, HPMC?
Hey there, I need to use low amounts of (about 5% active) surfactants (SLS + Cocamidopropyl Betaine or just SLS) and would like to achieve form of thick liquid - like dishwashing liquid viscosity.
I am also using MGDA and pH of about 5-6.
I have tried with Xanthan Gum - it thickens well but kills the foam and bubbles.
I have tried it with salt and/or sodium sulfate without xanthan gum. It foams much better, but I find it less reliable. I would love to use any powder thickener/gum, but without that feeling of the foam being “glued down” like in Xanthan Gum.
I am thinking about cellulose variants - CMC, HEC, HPMC.
I haven’t had a chance to try them yet - difficult to get.
Do you have any suggestions? Would that cellulose variants won’t be killing the foam and bubbles much?
Thank you!!!

Hi,
Hydroxypropyl methylcellulose (HPMC) is great for surfactant systems. It actually boost and stabilises the foam. Proper processing method is important.
Good luck!
