Free-From Nail Polish:
12 Chemicals Brands Leave Out
"5-free", "10-free" and "21-free" tell you how many ingredients a brand chose to leave out — the FDA doesn't define these terms, and every brand's list is different. "Free-from" describes what's not in the bottle. It is not a safety promise, including during pregnancy.

The 12 chemicals most often left out
These are the ingredients that appear most often on free-from lists, with the reason brands usually give. Inclusion here doesn't mean a polish containing them is unsafe as sold — it explains why brands choose to exclude them.
| Ingredient | Why brands leave it out |
|---|---|
| Formaldehyde | Used in some nail hardeners and older polishes. Classified by IARC as a Group 1 carcinogen; FDA notes it can cause skin irritation and allergic reactions. |
| Toluene | A solvent for smooth application. FDA notes its use in nail products is being phased out. |
| Dibutyl phthalate (DBP) | A plasticizer that reduces chipping. FDA's 2010 survey found it in only a few polishes; it is prohibited in EU cosmetics. |
| Formaldehyde resin | Tosylamide/formaldehyde resin adds adhesion and gloss, and is a known contact allergen for some people. |
| Camphor | Adds shine. Many free-from brands leave it out because of its strong odor and potential to irritate. |
| Triphenyl phosphate (TPHP) | A plasticizer. A 2015 Duke University–EWG study found a TPHP metabolite in women's urine after they painted their nails. |
| Xylene | A solvent some brands remove for odor and irritation reasons. |
| Ethyl tosylamide | A plasticizer that some free-from brands choose to exclude. |
| Parabens | Preservatives many brands leave out based on customer preference. |
| Other phthalates | Plasticizers beyond DBP that longer free-from lists also exclude. |
| Animal-derived ingredients | Such as carmine (red pigment) or guanine (shimmer) — left out of vegan formulas. |
| Added fragrance | Left out to reduce the chance of fragrance allergy. |
What the number on the bottle doesn't tell you
- Lists differ. One brand's "10-free" isn't another's. Read the INCI ingredient list.
- Replacements matter. Leaving one plasticizer or solvent out means using another. Ask what's used instead.
- "Non-toxic" and "clean" aren't legal terms. "Formulated without…" followed by specific ingredients is clearer and more honest.
- Ventilation still matters. FDA advises good ventilation whenever you use nail products.
If you're pregnant
Talk to your doctor about nail products. Use polish in a well-ventilated room, keep sessions short, and avoid long stays in poorly ventilated salons. No free-from label — ours or anyone else's — replaces medical advice.
For brands: making a free-from line
We make 21-free and vegan polish for private label brands from 100 units. On your label and listings, use "formulated without" claims tied to a specific list, and avoid "safe", "non-toxic" or "pregnancy-safe" wording you can't substantiate. See 21-free nail polish and 21-free vs 10-free vs 5-free.
