Micas

They're minerals formed when rocks are exposed to extreme heat and pressure. There are more than 20 different kinds because of all the ways they're created in nature!

Mica minerals are usually a shiny, flaky substance that can be peeled off into thin layers. They're extremely fine and they come in a variety of naturally-occuring colors. Some micas are mined in unsafe conditions using child labor. Ours are not - we confirmed that with our vendor before bringing any colors in.

Are they natural?
Micas are a naturally-occuring mineral. However, once they're mined they're coated with pigments, FD&C dyes, or a combination of the two.

FD&C dyes are synthetic and pigments are nature identical - that means they’re the exact same chemical structure as the platelet minerals found in the earth, but they’re created in a lab to remove impurities like lead and arsenic. Industrywide, pigments are considered natural because they don’t contain synthetic dyes.

You can find the ingredients for our micas on the product pages. The term natural is not regulated, so what you call them is up to you. If you're not sure, we always recommend erring on the side of caution and leaving the term "natural" off your labels.

Cold process soap
Micas are a great option for cold process soap. Just mix 1 teaspoon of mica with 1 tablespoon of a lightweight oil like sweet almond or avocado. Add 1 dispersed teaspoon at a time at trace until you get a color you like. We recommend about 1 dispersed teaspoon per pound of soap. Learn more in the How to Color Handmade Soap article.

Keep in mind, some micas can morph or fade in cold process soap. Check the product pages for performance notes. They also won't look as shimmery in the opaque bars. You can sprinkle them on top or in between the layers.

Melt and pour soap
Micas work well in melt and pour, and the shimmer really pops in clear bases. To use, add the color straight to the melted soap and stir well. If you see bubbles forming, spritz with alcohol and continue mixing. You can use up to ½ teaspoon per pound of soap.

You can also mix 1 teaspoon of mica with 1 tablespoon of 99% isopropyl alcohol. Add ¼ teaspoon of dispersed color to the melted soap until you get a color you like. This method helps the color mix in more quickly.

Other bath and body products
One of the reasons micas are popular is because they're so versatile. They can be used in pretty much every DIY bath and body product - lotion, bath bombs, scrubs, bath salts, etc. Eye-safe micas can be used in shadow and lip-safe micas can be used in balm, gloss, and lipstick.

If you're making a dry product like bath bombs, start with 1/8 teaspoon of mica in the powder and mix well. Then, add the liquid ingredients. For liquid products like lotion, you can start with 1/8 teaspoon of mica in the oil, or mix it with your fragrance or essential oil before adding it to the main batch.

Micas are oil-based colorants, so they will settle in water-based products like toners and room sprays. 

Pigments

These are powdered colorants made from oxidized metals like iron and titanium. Compared to micas, they're not as fine and they don't have any shimmer. They create vibrant matte shades in soap - a little goes a long way.

They're nature identical. They're the exact same chemical structure as the materials found in the earth, but they’re created in a lab to remove impurities.

This is where pigments work best. Just mix 1 teaspoon of the color with 1 tablespoon of a lightweight oil like sweet almond or avocado. Add 1 dispersed teaspoon at a time at trace until you get a color you like. We recommend about 1 dispersed teaspoon per pound of soap.

You can also use them to create lines of color in between layers, or to dust on top of soap. Just use a light hand so the layers stick together and there's not too much transfer when you use the bars.

Melt and pour soap
In general, micas are better for melt and pour - they mix in more easily because of their fine texture. Pigments tend to clump and leave streaks of color.

If it's all you have on hand, you can make it work! Mix 1 teaspoon of pigment with 1 tablespoon of glycerin or 99% isopropyl alcohol. Add ¼ teaspoon of dispersed color to the melted soap until you get a color you like.

You can also use our Color Blocks. They're concentrated melt and pour, so they incorporate more easily into soap than loose pigments.

Other bath and body products
We don't recommend pigments for other recipes. They can clump and leave streaks of color in the finished products. They work best for cold process soap.
