Get to Know: Mica Minerals
The ever growing world of mica minerals in natural beauty regimes are popular for good reasons. They are used to add color and luster to our cosmetics, as well as natural body care products like toothpaste.
Mica is a mineral name given to a group of minerals that are physically and chemically similar, often found in layers of rock. In fact, the term mica has become so well known, it is often considered a mineral of its own, when that isn’t quite the case. Mica minerals actually refers to a group of about 30 minerals in the class phyllosilicates. Micas are significant rock forming minerals found in igneous, metamorphic and sedimentary rock. Interesting note, the silicate sheets are composed of interconnected six membered rings. These rings are responsible for the micas typical six sided hexagonal symmetry, in which in ring shares three of their oxygens with three others. Actually, the mica minerals are similar to clay minerals, with the difference being clay includes other layers between silicate layers.
In cosmetics, we see why the word mica means “to glitter,” in their lovely and vibrant colors and the minerals ability to reflect light. But not all mica minerals are necessarily safe to use, so do your research. We find mica minerals are sometimes used in animal testing (not ours of course, we looked into it!). IN additional, although mica minerals are all natural, they are often synthetically created to be replicas of their natural occurring counterparts. Sometimes in the manufacturing product, you end up with the addition of heavy metal compound like bismuth oxychloride, which is used to create a white pigment . Although FDA approved, naturalists commonly recommended avoiding this compound as there still seems to be some questioning regarding its safety. It is at least, often found to be an irritant. In addition, just because it is mineral make up, doesn't mean it is all natural. Micas are often the carrier of artificial colors, so watch our for your dyes. Kainat Beauty carefully selects minerals that are safe for eyes and lips, and have no artificial colors added.
