Our glitter products have been guaranteed to be solvent resistant by the manufacturers and/or suppliers. This should give us assurance that all glitters thus identified will not do what we don't want them to do in our suspension base. That said, these glitters are not tested in all bases so the statement comes with that over-riding qualification.
That being said, we at Frank and Shine Designs have spent months testing samples of glitters from suppliers and manufacturers around the world. We continue to test as supplies arrive. Even so we cannot positively guarantee that products will not change over extended periods of time. Recent point in fact is fluoro glitters in US indie polishes which bled after 12 months submersion.
We try our hardest to supply the best products but consumers need to be sure for themselves if longer term change is important to them and test for that if need be.
