What are cosmetic mica powders?

Cosmetic mica powders are great natural colourants that come in a wide variety of shades and effects.

They are widely used in cosmetics, from soap making to lip balms, from eye shadow to nail varnish.

However, there are wider uses for mica powders  - they can be used for arts and crafts for beautiful colours and effects, think scrapbooking and card making.

So what are they made from?

Mica powders are made from a couple of ingredients, the main one being mica (unsurprisingly!)

Mica is a naturally occurring mineral found all over the world, which is then coated with other naturally minerals such as iron oxide and tin oxide to name just a few.

Some mica powders are artificially dyed, but we don't stock artificially dyed mica as we try to keep our ingredients as natural as possible. Also, dyed mica powder can bleed a little in soap.

Are they natural?

In our opinion, yes, mica powders are the most natural type of colourants available, especially when compared to liquid colourants.

Where are they sourced from?

Mica is often sourced from India, however due to the use of child labour in mica producing areas of India, we don't source any of our mica powders from India and only use reputable suppliers.

 

 

Can I use all of your colours on lips?

Unfortunately our green shades are not suitable for use on lips, but all of our other mica powders are.

How much mica powder do I need?

Well, it's hard to say, it depends on what you intend to use your mica powder for. But here are some guidelines:

Melt and pour soap: 1-3 %
Cold process soap: 3-5 %
Nail varnish: 8-12 %
Liquid soap: 0.2-1 %
Lip balms: 3-5 %
Lipstick: 10-20 %
These percentages are based on the total finished product weight, so if you intend to produce 1kg of melt and pour soap, you need 1-3% of that weight in mica powder - which is 10-30g.
If you use an amount towards the lower end of the scale you will have a more subtle colour, and a higher amount will give a more intense colour.

Can I use your mica powders in bath bombs?
Yes, but we strongly recommend using polysorbate-80 in your recipe otherwise the mica powder will not be absorbed into the bath water and will float on top, leaving a stain on the bathtub - which no one wants!
Can you provide all the technical information about your mica powders?
Yes, simply contact us and we'll send it right over to you!
