The nail polish industry has undergone a major transformation in recent years, moving towards healthier, non-toxic formulas, aka Free Formulas, that are safer for consumers and the environment. If you’ve ever shopped for nail polish, you may have noticed labels like 5-Free, 7-Free, or 10-Free, but what do these terms mean?
These labels refer to the number of harmful chemicals removed from the nail polish formula. In this article, we will explain the meaning of 5-Free, 7-Free, and 10-Free nail polish, why they matter, and how to choose the safest option for your nails.
Understanding the Free Formula Concept
Traditional nail polishes contain toxic chemicals that could harm human health and the environment. Due to rising concerns over safety, brands have started eliminating these poisonous ingredients, creating “Free” formulas that exclude certain chemicals.
The most common “Free” formulas include:
- 5-Free: Free from the top 5 toxic chemicals.
- 7-Free: Free from 5 harmful chemicals + 2 additional harmful substances.
- 10-Free: Free from 7 toxic ingredients + 3 more harmful additives.
The higher the number, the safer the formula is for your nails and overall health.
What is 5-Free Nail Polish?
A 5-Free nail polish eliminates five major toxic ingredients commonly found in traditional nail polish formulas. These chemicals have been linked to various health concerns, including allergies, respiratory issues, and even cancer.
The 5 Toxic Chemicals Removed in 5-Free Nail Polish:
- Formaldehyde – A known carcinogen used as a hardening agent. It can cause skin irritation, breathing issues, and allergic reactions.
- Toluene – A solvent that helps polish dry smoothly but is linked to nervous system damage and reproductive toxicity.
- Dibutyl Phthalate (DBP) – A plasticizer that makes polish flexible but is known to cause hormonal imbalances and reproductive health concerns.
- Formaldehyde Resin – A derivative of formaldehyde that can cause skin allergies and dermatitis.
- Camphor – Gives polish a glossy finish but can cause dizziness, nausea, and liver toxicity when inhaled in large amounts.
Why Choose 5-Free Nail Polish?
✅ Safer for nails and overall health
✅ Less likely to cause skin allergies and irritation
✅ A good balance between safety and performance

Final Thoughts: Is 10-Free Always the Best Choice?
While 10-free nail polish is the safest, performance should also be considered. Some 10-free formulas may not last as long or provide the same shine as 5-free or 7-free polishes.
If you’re concerned about toxicity, especially if you’re pregnant or sensitive to chemicals, 10-Free is the best option. However, if you want a balance between performance and safety, a 5-Free or 7-Free polish might work better.
