5 stars! So, here's the deal. This black dye does have an odor. It reminded me of a pair of new black jeans. BUT the moment I added it to my melted soy candle wax at around 160-170 degrees, the smell went away. The recommended drops to color my wax was off, I added a few more, but in the end I was left with perfectly black candles without the odor tampering with the scents I added to my candles. I will buy again.
