For 69ron's D-Limonene Mescaline Extraction would it matter if the calcium hydroxide I use isn't food safe?
I bought hydrated lime but the only kind I could find says it's not edible.

What was it sold as? What are the laws relating to 'food safe' labeling in your area, and which of the criteria does this product not meet?

depends.. its very possible it works for extraction fine, and the 'not edible' might just be a warning that doesnt necessarily mean it has something nasty in it but, unless you can find more info on what possible impurities it has, there's a risk, an uncertainty associated to using it... what if the impurity is something that reacts with or is soluble in non polar solvent and ends in your final product? If I were you I would keep trying to find some food safe one, and/or try to find more info on this specific brand you got, what it might have inside of it. But do as you wish

(and yeah, good questions from touche guevara)

It's Bonide Hydrated Lime
Calcium 34.20%
Magnesium 20.40%
Minimum Calcium Oxide 46.50%
Minimum Magnesium Oxide 32.00%
Calcium Carbonate Equivalent 131.70%
effective neutralizing value 129.52%
Derived from calcium hydroxide
lime score 130.38
that's what the bag says, and it's meant for soil

My package on it said "Edible Lime - Not for Human Consumption" or something similar, I was sure to order food grade though.

Don't really know the answer to the question though

doesn't matter
it's not going to be soluble in the nonpolar phase anyway.
