Cosmetic powders are typically screened at 60 to 400 mesh (250 to 37 microns) depending on the application. Mineral makeup and pigments require fine screening at 200 to 400 mesh, while talc and body powders use 100 to 200 mesh. Coarser cosmetic ingredients like bath salts and exfoliants are screened at 10 to 60 mesh for size grading.
Particle size control is critical in cosmetics because it directly affects product texture, color uniformity, skin feel, and consumer perception. A single visible agglomerate in a premium face powder can result in a customer complaint or product return. Screening removes agglomerates, oversize particles, and foreign material while ensuring consistent particle size distribution across every batch. ScreenerKing supplies precision stainless steel screens to cosmetic manufacturers for pigment, powder, and mineral makeup processing.
Recommended Mesh Sizes by Application
| Material / Application | Mesh Size | Micron Size | Purpose |
|---|---|---|---|
| Talc / body powder | 100–200 mesh | 150–75 µm | Remove agglomerates, ensure smooth texture |
| Face powder / loose foundation | 100–325 mesh | 150–45 µm | Ultra-fine screening for silky finish |
| Pressed powder blend | 80–200 mesh | 180–75 µm | De-agglomerate blended ingredients before pressing |
| Iron oxide pigments | 200–400 mesh | 75–37 µm | Remove agglomerates for uniform color |
| Mica / pearlescent pigments | 60–200 mesh | 250–75 µm | Grade by flake size for desired shimmer effect |
| Titanium dioxide | 200–325 mesh | 75–45 µm | De-agglomerate for sunscreen and makeup |
| Mineral makeup blend | 100–200 mesh | 150–75 µm | Final check screen before filling |
| Bath salts / bath bombs | 10–30 mesh | 2,000–595 µm | Grade crystal size, remove fines and oversize |
| Exfoliant particles (pumice, walnut shell) | 20–60 mesh | 841–250 µm | Classify abrasive particle size for skin safety |
Factors That Affect Mesh Selection for Cosmetic Powders
- Texture and skin feel: Finer particle sizes produce a smoother, more luxurious skin feel. Premium face powders and foundations demand 200+ mesh screening to eliminate any grittiness perceptible to the consumer.
- Color consistency: Agglomerated pigments create uneven color distribution. Screening at fine mesh ensures pigment particles are fully dispersed, producing consistent color from batch to batch and across the product surface.
- Electrostatic charge: Cosmetic powders, especially talc and mica, develop significant static charge during processing. Static causes blinding, material adhesion, and inaccurate separation. Grounding, humidity control, and ionizing equipment help manage static.
- Batch size: Cosmetic batch sizes are often small (50 to 500 lb per batch). Small batches favor smaller screeners that are easy to clean between color changes and product changeovers.
- Regulatory compliance: FDA (US), EU Cosmetic Regulation, and other frameworks require cosmetic products to be free from physical contaminants. Screening is a critical step in meeting these requirements.
Screen Material Recommendations
316 stainless steel is the recommended screen material for cosmetic powder screening. Cosmetic manufacturing involves cleaning with solvents, isopropyl alcohol, and sanitizing agents that can corrode standard stainless steel. 316 SS provides the best chemical resistance for cosmetic environments.
304 stainless steel is acceptable for dry cosmetic powder screening in facilities that do not use aggressive cleaning chemicals. 304 SS costs less and provides adequate performance for many cosmetic applications.
T-430 stainless steel is used in cosmetic facilities that employ magnetic metal detection as part of their quality program. T-430 screens are magnetically detectable if a wire fragment enters the product.
Equipment Recommendations
- Artisan and small cosmetic labs (under 200 lb/hr): ScreenerKing SiftPro 18" — perfect for small-batch pigment screening and mineral makeup processing. Easy to clean between color changes.
- Mid-size cosmetic manufacturers (200–2,000 lb/hr): ScreenerKing SiftPro 24" or 30" — handles production-scale screening for face powder, talc, and pigment processing.

- Industrial ingredient suppliers (8,000+ lb/hr): ScreenerKing SiftPro 60 — bulk pigment and mineral processing for cosmetic ingredient suppliers.
Frequently Asked Questions
What mesh size is used for face powder and foundation?
Face powders and loose foundations are typically screened at 100 to 325 mesh (150 to 45 microns). The fine mesh ensures a silky texture free of grittiness. Pressed powder formulations may use 80 to 200 mesh depending on the desired finish.
Why is screening important for cosmetic pigments?
Pigments must be free of agglomerates, oversize particles, and foreign material to ensure uniform color, smooth texture, and consumer safety. Screening at 200 to 400 mesh breaks up agglomerates and removes contaminants for batch-to-batch color consistency.
What screen material should I use for cosmetic manufacturing?
316 stainless steel is recommended because cosmetic manufacturing involves cleaning with solvents, alcohol, and sanitizing agents. 316 SS provides superior chemical resistance while meeting FDA and EU cosmetic safety regulations. ScreenerKing offers 316 SS screens in all sizes from 18 to 60 inches.
