Does anyone know the chemical composition /active ingredients of the excellent hair dye called (in English transliteration: sorry I cant do GB) "yina"? Seems to have rather mysterious properties, eg over a long time something volatile leaks from a plastic baggie, right through the plastic, to stain things nearby. A grain of it on a glass coverslip leaves on white rubber mat below a brown stain outlining the glass barrier. This takes a few days. Stains some kinds of paper purple like iodine, but chem assay for I is negative. Seems three kinds of grain: soap + dark grains making 2 colors. Mildly heated, it deposits colorless fine needle crystals a little distance away. Seems no heavy metals (Pb) in it. Any chemist listening? Thanks from art@cochise.biosci.arizona.edu
