If you check DIY Cosmetics site, you will find information about this. I'm going to bump this up on my priority list -because now you have me all curious! Thanks for the inspiration!LisaLisehttps://www.blogger.com/profile/14566391113401195535noreply@blogger.comtag:blogger.com,1999:blog-2131647485414323768.post-91154983642189581682015-04-15T04:39:49.020+02:002015-04-15T04:39:49.020+02:00Thank you for your response, Lisa.

I just ran across this information on a soap making post explaining the differences between pigments (oxides, ultramarines), fd&c colorants, micas, and herbal colorants - seems to mirror the FDA info. Although she explains that "micas are the individual mica (which looks like a platelet) is coated with FD&C colorants, or pigments, or a combination of both to achieve the colorant." http://teachsoap.com/2012/03/24/soap-coloring-options/ I would love to use micas, but still unsure since they are mined and untested for purity, and if this resource is correct they are coated with synthetic pigments. Right now I am using herbal colorants and straining but I lose about 30% oil doing so and it is such a messy process. Anyway, thanks for all you do. I'll be interested to hear more "before long". =0) I get that and am amazed how much content you get out in the mist of making products. All the best!Carolhttps://www.blogger.com/profile/03402718246336845739noreply@blogger.comtag:blogger.com,1999:blog-2131647485414323768.post-36995951601326901412015-04-13T12:48:12.430+02:002015-04-13T12:48:12.430+02:00hey there Carol - thanks so much for your kind wor...hey there Carol - thanks so much for your kind words. You and I are both huge fans of Susans blog!<br /><br />Your question is very timely, as I am working on a bit of research into the use of metals and minerals in make-up and plan on doing a post on this before long (don't take that literally-- sometime 'before long' turns out to be a year if that's where the research takes me)-<br /><br />Meantime, I can recommend DIY cosmetics as a reliable source of both product- but also information. <br /><br /><br />But- to give you a bit of an immediate reply - I checked the FDA page - which says micas are exempt but still must comply when used in cosmetics---<br /><br />Quote:<br />"Colors exempt from certification. These color additives are obtained primarily from mineral, plant, or animal sources. They are not subject to batch certification requirements. However, they still are considered artificial colors, and when used in cosmetics or other FDA-regulated products, they must comply with the identity, specifications, uses, restrictions, and labeling requirements stated in the regulations [21 CFR 73]."<br /><br /><br />Find the page here<br />http://www.fda.gov/ForIndustry/ColorAdditives/ColorAdditivesinSpecificProducts/InCosmetics/ucm110032.htm<br /><br /><br />I hope this was of some help!<br /><br />LisaLisehttps://www.blogger.com/profile/14566391113401195535noreply@blogger.comtag:blogger.com,1999:blog-2131647485414323768.post-79829399503428128072015-04-12T21:14:13.593+02:002015-04-12T21:14:13.593+02:00Hi Lisa, I have learned so much from you and reall...Hi Lisa, I have learned so much from you and really appreciate your blog/site! (Found you from following POI - love her blog too). I am curious your thoughts on sourcing mica and how you determine the highest quality? My understanding is that "coal tar color" must be batch tested for heavy metal levels and purity and therefore certified before hitting the market (source - a consumers dictionary of cosmetic ingredients - pg167). I understand coal tar colors are not the same as micas, but just trying to see if micas are regulated the same. On the cosmeticsinfo.com site (under Mica - overview) it says "the levels of heavy metals in Mica are regulated by the FDA, and the small amounts that may eventually be in cosmetic or personal care products do not pose a risk to human health". But on the safety page it says "the Food and Drug Administration (FDA) lists Mica as a color additive EXEMPT from certification". I'm confused, FDA says it is safe, but then doesn't require certification. My question is - does mica get batch tested for heavy metal levels and purity or not? Do you have a supplier that you trust for purity and heavy metals? Thank you so much for your time!Carolhttps://www.blogger.com/profile/03402718246336845739noreply@blogger.comtag:blogger.com,1999:blog-2131647485414323768.post-36400227476417920532013-07-12T11:06:05.514+02:002013-07-12T11:06:05.514+02:00Thank you Anon.
