@Bill_Toge
I obtained a copy of the Indian Standard  IS 7159:1984-thank-you for the suggestion! I am  having difficulty obtaining specific results reports from the Bureau for batches tested from suppliers.
Any idea who else would hold copies of the batch test reports done under  IS 7159:1984

I don’t understand why you should get an exothermic reaction from ground-up dried plant leaves. It’s cellulose, right? Try the same experiment with some other type of ground dried plant leaves. Tea, for instance. Do you still get a reaction?

I know! and I got the test from EVERY single brand. Ok I will try soe tea and maybe some cinnamon bark.

What is the exothermic reaction indicating?

I poured a teaspoon of the henna powder into the ammonia + 40volume hydrogen peroxide mix and got a highly exothermic reaction… for every sample for evey single natural brand i tried… don’t know what to make of tht.

as for HPLC, back in the day i ued to work in a chromatog lab on campus so I coulda run samples there but now I cant find a place that wants to charge me less thn $1000 o=per test. Can’t exactly afford that right now.,.. Is there way to get HPLC testing for less?

Thanks Bill_Toge fir the info. I guess the ISB (insian stndards bureau has all that info for exporters..)

Perry, I am using it for an all natural hair colour. 

Here’s the thing:
I used that test that they do in salons, the “compatibility test” ammonia + 40volume hydrogen peroxide mixed in henna powder and waited for a reaction (it is supposed to remain inert if no metallic salts are present) I bought a sample of EVERY local providers’ natural organic henna powder and they ALL reacted.,.. so I grew suspicious of the test… 

Any ideas?

Thanks
