Cosmetic pearl pigments are the same broad chemistry as industrial ones, but they are sold into a different regulatory universe. The dividing line is not "purity" in the abstract — it is the permitted-use list for colourants in the destination market and the documentation that proves a given grade sits on it.
In the EU, cosmetic colourants must appear on the permitted list in the cosmetics regulation, with restrictions that vary by application area — the eye area, the lips, and the rest of the body are treated differently, and some entries are limited to products that are rinsed off. The practical implication for a formulator is that two visually identical powders can have different permitted uses. Build your shade card around compliance, then match colour, rather than the reverse.
| Product type | Typical particle-size direction | Why |
|---|---|---|
| Pressed eyeshadow | Fine to mid, narrow distribution | Even payout, good pressability, no grittiness |
| Loose powder / highlighter | Mid to coarse | Visible sparkle and light-catching highlight |
| Lip products | Fine, tightly specified | Mouthfeel; coarse flakes feel gritty |
| Blush / bronzer | Fine to mid | Blendability over a larger area |
| Nail and body art | Coarse and flake | Visual impact matters more than feel |
Q1: Can one grade serve both eyeshadow and nail art?
Compliance-wise they must both be permitted for the intended use, and the particle size that feels right on the eye is usually too fine for nail art. Most brands specify two or three grades.
Q2: What documentation should come with every batch?
Batch COA, TDS, SDS, and a declaration of permitted-use status for the target market. Keep them together with your Product Information File.
Q3: Are cosmetic pearl pigments subject to Annex IV?
In the EU, cosmetic colourants must appear on the permitted list in the cosmetics regulation, with restrictions varying by application area — eye, lips and body are treated differently, and some entries are limited to rinse-off products. Build your shade card around compliance, then match colour. See quality standards.
Q4: How do I choose particle size for eyeshadow, lip or blush?
Pressed eyeshadow favours fine-to-mid narrow distribution for even payout; lip products need fine tightly specified grades for mouthfeel; blush/bronzer use fine-to-mid for blendability; nail and body art can use coarse flakes for visual impact. See the pearlescent pigment range.
Q5: Do binder systems affect pearl pigment performance?
Yes. Anhydrous pressed powders reward narrow PSD and a binder that wets the flake without dissolving the coating; cream/gel need full dispersion before setting; emulsions risk pigment migrating to the interface — check stability under accelerated ageing. The TiO₂-free guide covers coating chemistry.
Q6: Can I use the same pearl pigment for eye and lip products?
Not necessarily — two visually identical powders can have different permitted uses because the eye area, lips and body are regulated differently. Verify the permitted-use listing for each application area before formulation. See certificates.
Q7: What documentation proves a cosmetic grade is compliant?
Hold the applicable certifications (such as FDA and Kosher where applicable) with TDS/SDS/COA on file, and confirm the grade's permitted-use listing for your market. Validate against the food-grade specification pack if the grade overlaps food-contact decorative use.
