I just bought a kit for henna tattoos from IMAX.net. It says deep black henna.
I am not sure now if this is safe to draw on the skin. I tried it out on my arm with applying it twice. The result is dark (strong coffee) brown.
The ingredients of the powder are as follows:
Henna Powder
Black Walnut powder
Sodium perborate
sodium sulfate
Sodium carbonate
toulene 2-5 diamine sulphate
Sodium carboxymetil cellulose
Resorcinol
Sodium isoascorbate.
Could somebody please tell me if this powder contains PPD?
