Frequently Asked Questions:


Q. Which Stardust Mica colors can I use on my lips and in my Bath Bombs?

A. Mostly all Stardust Micas can be used in your Bath Bombs and on your Lips. With the exception of the Blue and Greens, basically colors that contain the ingredients Ultramarine Blue and Chromium Oxide Green. The Neon colors have a Safe Use: Soap Making - label only

Q. Do all Blue and Green colors have Ultramarine Blue and/or Chromium Oxide Green?

A. It would be difficult to make a generalized statement. But it’s safe to assume that all blue and green mica pigments would have either Ultramarine Blue and/or Chromium Oxide Green. Please, before purchasing; refer to our jar labels in order to see what is contained in the SM color you are buying, then determine if it’s recommended for use in your intended purpose. Gathering this information will be important to follow when it comes time for you to label your products for proper resale

Q. Is there a Blue mica powder that can be used in Bath Bombs? It's just for painting a small design on it...

A. We are not aware of any mica powders colored with Ultramarine Blue that have a Safe Use label for Lips (use in Bath Bombs). We’d recommend using batch certified FD&C dyes to color bath bombs

Q. Which of your mica powders contain Ultramarine Blue and/or Chromium Oxide Green?

A. The mica powders which contain Ultramarine Blue or Chromium Oxide Green will have that ingredient listed on the jar. Also, for more detailed information on ingredients and Safe Use please see the SDS sheets available for download on our website, and on the Amazon product description page for our products

Q. Why aren’t Ultramarines and/or Chromium Oxide Green, good for use in Bath Bombs

A. The ingredient Ultramarine Blue for the blues and Chromium Oxide Green, is not recommended for use on Lips by the FDA. It is also unknown why the FDA has stated that these colors are not recommended for safe use in the aforementioned application

Q.  Are Ultramarines and Chromium Oxide Green OK to use in bath bombs 

A. These safe use reasoning  for these colorants remain in a ambiguous area, they aren't stated as having a safety issue, nor are they recommended to use in products that will have a label stating “General” use, the "Lips" label in our case. The FDA classifies the aforementioned colorants as not recommended for use on lips. We have not found any other reports or articles as to why these colorants do not carry a Safe Use: Lips label. It is also known that the EU cosmetics regulations (European Union) which covers similar recommendations for Europe and Canada, does not restrict the use of these colorants in their covered territories. This often can cause confusion for people who see Safe Use for Ultramarine Blue and Chromium Oxide Green from vendors who’ business originates in those countries covered by the EU laws.
