2. Resins and Plasticizers
These ingredients add flexibility and help the polish stick to your nails without cracking.

Examples: Tosylamide/formaldehyde resin, camphor, triphenyl phosphate (TPHP)
Purpose: Prevents chipping, boosts shine, and ensures polish doesn’t get brittle.
⚠️ Some can be irritants or potential hormone disruptors (e.g., TPHP).
3. Solvents
Solvents keep the polish fluid until application, then evaporate to allow drying.
Examples: Ethyl acetate, butyl acetate, isopropyl alcohol
Purpose: Helps the polish spread evenly and dry quickly.
⚠️ Can be drying or irritating, especially in poorly ventilated spaces.

4. Colorants and Pigments

These provide the vibrant (or subtle) hues and effects you see in polish.

Examples: Iron oxides, titanium dioxide, FD&C dyes, ultramarines
Purpose: Adds color and visual effects like shimmer or matte finishes.
✅ Usually safe, but glitters can be made from microplastics—not eco-friendly.

5. UV Stabilizers
These help protect nail polish from fading or yellowing when exposed to sunlight.

Example: Benzophenone-1
Purpose: Preserves color and finish over time.
⚠️ Potential endocrine disruptor—use in moderation
