More About Coloured Mica
What Is Coploured Mica?
Coloured Micas (or Pearlescents) are beautiful natural colours that are created by coating muscovite mica flakes with high heat resistant iron oxides, ultramarines or dyes.
What Is 'Natural'
'Natural' is a word that is often used to describe products or ingredients. The definition of 'natural' according to the Oxford English Dictionary means 'existing in or derived from nature; not made or caused by humankind'. Coloured micas are made from ingredients formed from mineral rocks and we can probably all agree that rock from the Earth is natural. Of course to put these crushed rocks onto your face or in your cosmetic products without refining and purifying them first would be totally irresponsible not to mention illegal!
How Are Coloured Micas Formed?
Coloured mica goes through a complex manufacturing process involving mica flakes, titanium dioxide and iron oxides or ultramarines depending on the end colour, to become the vibrant colours that we have all come to know and love. For cosmetic use, coloured micas must then go through an extra process to refine and purify them even further which brings them to cosmetic grade standards for use in all products defined as cosmetic.
What Can Coloured Micas Be Used In?
They are used in a wide variety of applications including decorative paints such as for car paintwork, wonderful effects can be achieved on the artists canvas as well as caligraphy. They are also used in card making, candle making (normally for surfact decoratin) and of course cosmetics including soaps.
Cosmetic grade coloured micas are most widely known for their use in mineral makeup and are the preferred choice for colouring mineral eyeshadows, lip products, blushers and more. They are also used by nail enthusiasts in nail polish and have gained incredible popularity as a natural alternative to colour soaps
Are All Coloured Micas The Same?
No... The colour range of coloured micas can cover the whole spectrum and beyond! Within that spectrum, you will then find certain colours can be metallic in nature, others iridescent, there are colour shifters as in chameleon and so many more. Then there is the system for size grading of coloured micas and in fact most mineral ingredients, this is done in microns. With coloured micas, generally the lower the micron size, the more inclined they will be to shimmer rather than sparkle and the coverage will be heavier. The higher the micron size the more sparkle they will have and less coverage.
To Dye Or Not To Dye?
Coloured micas coated with artificial dyes can bleed in soap, so when buying coloured micas for soap making, it is always best to check with your supplier on which type of micas they stock.
We choose not to stock coloured micas containing artificial dyes as we prefer to keep our products as close to 'natural' as possible.
Coloured Micas In Cosmetics
Add them singularly to pre-mixed eyeshadow bases for stunning eyeshadows or make up your own tailor made colour blend by mixing a few together. They are not limited to eyeshadows either, some of the more muted pinks, lilacs, peaches and browns can be added to blusher bases to give a very attractive effect.
