Anyone have experience with color indicating silica gels?

I know the blue comes from toxic cobalts, but the orange/green variant is supposed to be safer.

the msds seems relatively benign.

I thought this shit was so cool I haven't even thought to wonder how it would change color bands in a column.....

Skyhighler, since you're great as disseminating info, and i love experimenting and then not saying shit.... maybe we should get together and try this shit out for folks to see.

From the linked MSDS,

Section 2: COMPOSITION & INFORMATION ON INGREDIENTS
CAS Numbers: 1343-98-2, 77-09-8 Molecular Formula: SiO2 nH2O + C20H14O4

That's silicic acid and phenolphthalein,

https://en.wikipedia.org/wiki/Phenolphthalein

Take a look at the SDS for phenolphthalein, mutagen and probable carcinogen,

I'm told it is methyl-violet responsible for the color. I imagine silicic acid and phenolphthalein are used in its synthesis. But how much is ACTUALLY on the surface of the beads or leeches out. I imagine the color change ability would leech out if anything were to leave the silica.

Oh im sure we could get a lab to test for their presence
