It’s the color of elegance and mystery. Use this dye to create a bold soap with all the powerful evocations of black. Combine with a white melt and pour soap base to produce a smoky gray color, or with a clear base to produce a deep, true black. Your actual experience may vary depending on your use of the base and the dye’s saturation. We encourage you to experiment and find the best combination to fit your needs. Expect to use two to three drops to achieve the most typical color range. In the example images, we used two drops per pound (454 g) of soap base.

Usage Recommendations:

  • Usage: 2-3 drops/lb (454 g)
  • Shake well before use
  • For melt & pour soap, lotions, and water-soluble bath products
  • Not for lip products

Note: This product is not recommended for cold or hot process soap. Color morphing may occur.

This black liquid dye is super rich in color, a little goes a looong way! Awesome in melt and pour, body washes and even lotion and body butters. Absolutely the best liquid dyes I've tried and I've tried many!

Well I didn't shake well before use so I am taking that into account. But using the black I put 6 drops in for the oatmeal shay better, and only got a light gray color. I also used the vibrant purple with this batch hoping to kind of get a swirl pattern through the soap while pouring it. The purple came put ok still a bit on the light side. Again I didn't shake well before hand so this might be why.

Works perfectly

As the detail of the product suggested, I used it in MP soap and everything came out beautiful. Made nice gray with white MP base, galaxy deep purple with red, blue and pigment, nice amber brown with yellow and red... Must have this black with other basic colors. I prefer using this liquid one over block ones. Very easy to use. I purchased 1oz bottle but you only need just a tiny bit to color the base. So I know this bottle last for awhile. Awesome over all.

I shake up the bottle really well and massage it so it heats up a bit and then I only need to use one or two drops for whatever project I'm making. Makes this worth it to buy because I know it is going to last so long! Works in bath bombs too! The black isn't as vibrant as other colors, but still good.

Not great

Shook it vigorously for almost a minute. 10 drops per lb still gave a medium gray color. Would not recommend.

Did not work at all for cold process and ruined the entire batch.

This color, amongst the other I tried to use (purple) did not work in cold processed soap. We used an olive/coconut oil base. This was less than a pound to make room for lye and water. We used less than the recommended at first. Absolutely no color distribution. We then added another 5 drops. No color distribution. We mixed and mixed and mixed and ended up with this extremely light gray. We added a few more drops and ended up with a darker gray. I'm sure it will darken to a black over time, however, I've never seen so much needing to be used to see a true-to-color response in the batches. We used a total of 16 drops to just get to the dark gray. The soap was traced so heavy it was impossible to pour. This was a little annoying considering something like mica powder shows a brilliant, true-to-color result. You would think with liquid drops it would be even easier. However, considering the purple came out light pink with over 10 drops, I'm not too thrilled with my purchases, especially since I bought multiple colors in the 1oz containers. Will not buy these again and I recommend turning to mica powders or dioxides.
