What vehicle base can be used with greater than 25% salt concentrations and also withstand a pH of around 1 (professional use)?

What about water? It’s a great vehicle and very stable.

Pharma said:What about water? It’s a great vehicle and very stable.Thanks for the water comment but I was looking for something that would provide some viscosity.
-
Ah, you’re looking for a salt-tolerant and acid-stable thickener… that’s not a vehicle base.Using the search function wouldn’t be the worst idea.
-
do you have any experience with Natrosol 250 or FlexiThix thickeners?
-
Sorry, no.

What about a modified cellulose? HEC is used for thickening HCL toilet bowl cleaner, I think it could work?
-
Natrosol is HEC
-
pH 1 plus cellulose = glucose syrup. Same goes for HEC.

The 25% salt content is doable, that highly acidic pH not so much. Colloidal clays (laponite?) may be able to do the job, but experiment is needed. Should you find success please share with the group.

At a pH of 1, clay will release quite a bit of its cations (lithium, sodium, magnesium) and its thixotropic behaviour might no longer be there… you’d have to try and see.

Perry thanks-as an aside, do you or anyone on this site have a USA supplier for
Poly(methyl methacrylate) (PMMA)
