Ingredient glossary / Colorant
Synthetic mica
On the label: Synthetic Fluorphlogopite · Colorant
What it is
Lab-made mica, purer and more uniform than mined mica, with no sourcing concerns.
Colorants: Colorants tint the product or the skin; in the US each is listed by its FDA name (CI number or D&C name).
In the research
3 PubMed papers mention it with skin, cosmetics or hair; the three most recent:
- Declared versus actual presence of PFAS in cosmetic products: an INCI list analysis and critical appraisal of current regulatory frameworks · Environmental science and pollution research international, 2026
- Development and validation of an ICP-MS method using ammonium fluoride to replace hydrofluoric acid for analysis of cosmetic ingredients · Journal of AOAC International, 2026
- Safety Assessment of Synthetic Fluorphlogopite as Used in Cosmetics · International journal of toxicology, 2015
A paper is a paper, not a verdict: titles are listed so you can read them, and a study on cells or mice says little about a cream on a face.

If a product causes a reaction, stop using it; a reaction that spreads or affects breathing is a call to a doctor or 911.
