Thickening with Hydroxypropyl Methyl Cellulose

Hi all. I am currently developing a liquid soap, and i am using HPMC as the thickening agent. It gives a pseudo plastic and stringy/slimy consistency. This stringy consistency is undesirable, I'd really appreciate any suggestion how to get rid of the stringy consistency (or any other thickening system recommendation). Thanks!

    It will depend on what else is in your formula and what pH. Is it a true soap or just surfactants?

    It is a true soap. For now, the formula only consists of fatty acids, KOH, Na4EDTA, Glycerin, HPMC. The pH is around 9.3

    Do you think soap from saponification can be thickened with salt like syndet? Because I've tried adding CAPB and/or non-ionic surfactant as a co-surfactant and then salt, but it didn't thicken.
