Can carboxymethylcellulose be used in place of methylcellulose?
Hi. I'm in Thailand, and all I can find online for purchase is carboxymethylcellulose, not methylcellulose. Does anyone know if carboxymethylcellulose can be used as a slowing agent in my water samples, or will the carboxyl group damage the sample? Thanks.

Hopefully you can find Cytrocell, a dietary product made with methycellulose, and used to thicken liquids, common in the drug section of grocery stores or at the pharmacy.

Oh, thanks. I see I can get that online here in Thailand, but it's about 4x as much as in USA. I'll pick some up next trip home.Greg Howald wrote: ↑Sat Oct 15, 2022 8:30 pmHopefully you can find Cytrocell, a dietary product made with methycellulose, and used to thicken liquids, common in the drug section of grocery stores or at the pharmacy.

I don't know hoe to spell it, but can you get Metamucil. It has been used to slow things down in pond water. Also glycerin has been used. They both increase the viscosity of the water. It's hard to swim in something that seem as thick as syrup.

I'll look for that. Thanks. I'm sure I can get glycerin. Thanks again.Greg Howald wrote: ↑Sun Oct 16, 2022 11:51 amI don't know hoe to spell it, but can you get Metamucil.

MC and even CMC should be better than glycerine for this purpose, since glycerine, besides being viscous, is a solvent (albeit much much weaker than ethanol for example). Anyway, if you try glycerine, I would suggest to start with very low concentrations. Much less (percentage-wise) than MC.macnmotion wrote: ↑Sun Oct 16, 2022 12:20 pmI'll look for that. Thanks.

True. I have watched things being destroyed by too much glycerin .

Glycerin has a strong osmotic effects which kills the organisms you want to slow down.
