Soap Notes

Ultramarines and oxides (pigments) are recommended in oil-based applications.

M&P Soap: We recommend a usage rate of about 1/10 - 1/8 teaspoon per pound of M&P soap. When mixing with M&P soap, blend in a few drops of glycerin or oil to make a smooth paste to avoid clumps in your soap. Pigments will appear bold and true to color in clear M&P soaps and will be somewhat muted (pastel-like) in white M&P due to the titanium dioxide whitener.

CP Soap: Usage rates vary but typical suggested usage in CP soap is 1/2 - 1 teaspoon per pound of soap. Over saturation will result in colored lather and will leave colored suds on fabric and may stain. Pigments are best for swirling as the colors do not “bleed” into one another and do not “migrate” or spread.

Non-Bleeding, Non-Migrating. Stable in high pH


Bath Bomb Notes

Not recommended for use in bath bombs.

Gorgeous brick red🤩

I normally use natural colorants only in my cp soap so it was a challenge to get a rich, deep reddish brown colour. I decided on a whim to try this red iron oxide and boy, I am in love!! The end color is a deep, rich red that blew me away. I am now hooked on Mad Micas and am starting another line of cp soaps just so that I can keep buying different colors.

Absolutely loving it

Great color cp soap. Fast on delivery. Will definitely buy again

Awesome quality, great company!!

(Picture shows Red Oxide + Voodoo Mica). SO excited to have found you guys. Quality of everything I've purchased so far has been amazing. Particularly easy to tell with the Red Oxide. The one I've been purchasing from Amazon makes a nice shade for my lipstick line, but it's a COMPLETELY different color (a little more orange). This Oxide is a true, deep red (more blue undertones).

I love knowing that these products are safe and ethically sourced and cruelty/animal free. Thank you for being a responsible company and doing the right thing, because it's right. Prices are awesome as well. Returning all of the micas I bought from Amazon and permanently instating MadMicas as my supplier :) <333

Great Products

I've purchased a couple of times from Mad Micas and never been disappointed. So far all their micas and oxides have performed great. And my order always arrives quickly.

Lovely Res

Beautiful deep red. Absolutely love the simple dramatic effect when paired with white!
