FDA Registration for Nail Polish Products
What's a cosmetic vs a drug in nail care, the color-additive rules, the toxic-trio and MMA issues, and the nail-fungus line.
Key Takeaways
- Nail polish & most nail products = cosmetics — MoCRA registration + listing.
- Color additives need FDA pre-approval — nail-approved colors, certified batches.
- The "toxic trio" — formaldehyde, toluene, DBP — drives "3/5/10-free" claims.
- 100% MMA monomer — FDA-actionable for artificial nails; ~32 states ban it (EMA replaced it).
- Nail-fungus treatment = drug — and OTC topical can't treat it (prescription only).
- "Free-of" claims must be true — and registration ≠ approval.
Nail Products: Cosmetic vs Drug
| Product | Category |
|---|---|
| Nail polish, base/top coats, gel polish | Cosmetic (MoCRA) — with color additives |
| Nail polish remover | Cosmetic (MoCRA) |
| Primers, artificial nail systems, adhesives | Cosmetic (MoCRA) — watch MMA |
| Nail hardener / strengthener (appearance/condition) | Cosmetic (MoCRA) — watch formaldehyde |
| Nail-fungus / antifungal "treatment" | Drug — and nail fungus is a prescription matter |
| Any nail product claiming to treat a disease | Drug |
Color Additives Need FDA Pre-Approval
Nail polish is color-driven, and color additives are the one area of cosmetics that requires FDA pre-approval:
- Only approved colors — each color additive must be FDA-approved and listed for its use
- Certified batches — FD&C/D&C straight colors must come from FDA-certified batches
- Per-shade listing — shades differ in color additives, so the listings reflect them
- An unapproved color makes the product adulterated — a real risk for imported shades
Ingredient Safety: the Toxic Trio & MMA
The "toxic trio." Formaldehyde, toluene, and dibutyl phthalate (DBP) are three ingredients historically common in nail products that raised health concerns — DBP a plasticizer/binder, toluene a solvent, formaldehyde in some polishes and hardeners. FDA doesn't pre-approve cosmetic ingredients, so it doesn't "ban" them outright; the concern drove reformulation and the "3-free" (no toxic trio), "5-free," and "10-free" marketing. Some states restrict them, and the onus is on the manufacturer to substantiate safety.
"Free-of" claims are claims. "3-free," "10-free," "non-toxic," and "formaldehyde-free" have no FDA definition, so they must be truthful and substantiated — the product actually is free of what it says. They don't change the cosmetic status or MoCRA obligations.
Nail Fungus: a Drug (and a Prescription One)
A nail product that claims to treat or prevent a condition — a fungal nail infection (onychomycosis) — is a drug, not a cosmetic. And there's an important twist:
- OTC topical antifungals aren't effective on nails — the antifungal monograph doesn't cover nails
- Nail fungus is a prescription matter — treated with Rx therapy under a professional
- An OTC nail polish claiming to cure nail fungus is an unapproved drug — a compliance and safety problem
The Cosmetic (MoCRA) Path for Nail Polish
- Facility registration + product listing + Responsible Person — via Cosmetics Direct; biennial renewal; U.S. Agent if foreign
- Color-additive review — approved colors, certified batches, per shade
- Ingredient screen — toxic-trio and MMA issues; substantiate any "free-of" claims
- Safety substantiation & adverse-event reporting — solvents, plasticizers, colors, sensitizers
- Compliant labeling — INCI (with colors), net quantity, adverse-event contact; truthful claims
Common Nail Polish Mistakes
- A color additive not approved for its use — especially imported shades
- MMA monomer in artificial nail products — FDA-actionable, banned in many states
- Unsubstantiated "3-free / 10-free / non-toxic" claims
- A "treats nail fungus" claim — turns it into an unapproved drug
- Registering the facility but not listing all shades
- Missing the U.S. Agent (foreign); "FDA approved" claims

Frequently Asked Questions — Nail Polish
1. Do nail polish products require FDA registration?
Yes. Nail polish and most nail products (removers, base/top coats, primers, hardeners, artificial nail systems) are cosmetics, so they're regulated under MoCRA: facility registration, product listing, a Responsible Person, safety substantiation, adverse-event reporting, and compliant labeling (foreign facilities also need a U.S. Agent). The exceptions are nail products that treat or prevent a condition - like a nail-fungus treatment - which are drugs. So the vast majority of nail polish is a cosmetic.
2. Do nail colors need FDA approval?
The color additives do. Nail polish is color-heavy, and color additives are the one area of cosmetics that requires FDA pre-approval - each must be approved and listed for its use, and certified colors (FD&C/D&C) must come from FDA-certified batches. So a nail polish line needs a color-additive review to confirm every shade uses approved colors. The finished polish itself isn't "approved" (FDA doesn't approve cosmetics), but its colorants must be.
3. What is the "toxic trio" in nail polish?
The "toxic trio" is formaldehyde, toluene, and dibutyl phthalate (DBP) - three ingredients historically common in nail products that raised health concerns. DBP is a plasticizer/binder, toluene a solvent, and formaldehyde appears in some polishes and hardeners. FDA doesn't pre-approve cosmetic ingredients, so it doesn't "ban" them outright, but the concern drove widespread reformulation and the "3-free" (no toxic trio), "5-free," and "10-free" marketing. Some states restrict these ingredients, and the onus is on the manufacturer to substantiate safety.
4. Are "3-free," "5-free," and "10-free" claims regulated?
There's no FDA-defined standard for "3-free," "5-free," or "10-free" - they're marketing claims about which ingredients a polish leaves out (starting with the toxic trio and expanding). Because they're claims, they must be truthful and not misleading, and you should be able to substantiate them (the product actually is free of the listed ingredients). They don't change the product's cosmetic status or its MoCRA obligations - a "10-free" polish is still a cosmetic that must comply.
5. Is MMA allowed in artificial nails?
Methyl methacrylate (MMA) monomer is effectively off-limits for artificial nails. In the 1970s FDA received injury reports (fingernail damage/deformity, contact dermatitis) tied to 100% MMA monomer products and removed them from the market through court action (injunctions, seizures, recalls). No single regulation flatly prohibits MMA, but FDA has treated it as actionable, and roughly 32 states ban it. The industry replaced it with ethyl methacrylate (EMA). If you make artificial nail products, MMA monomer is a serious problem; primers may also be marketed "acid-free" (no methacrylic acid).
6. When is a nail product a drug?
When it's intended to treat or prevent a condition. The clearest case is a nail-fungus (onychomycosis) treatment - claiming to treat a fungal infection makes the product a drug. Importantly, OTC topical antifungals are recognized as "not effective on nails," so nail fungus is treated with prescription therapy; an OTC nail polish claiming to cure nail fungus is an unapproved drug. A nail hardener that just hardens/strengthens the nail's appearance is a cosmetic, but a nail product with a treatment claim is a drug.
7. Can my nail polish claim to treat nail fungus?
No - not as an OTC cosmetic or OTC drug. Treating nail fungus is a drug claim, and OTC topical antifungals aren't recognized as effective on nails, so nail fungus is a prescription matter. An OTC nail product claiming to treat or cure nail fungus is an unapproved new drug and a compliance and safety problem. A cosmetic nail product can strengthen or improve the look of nails, but it can't claim to treat a fungal infection.
8. Is a nail hardener a cosmetic or a drug?
A nail hardener that strengthens or improves the appearance/condition of the nail is generally a cosmetic. Some hardeners have historically used formaldehyde, which is a known skin sensitizer/allergen - so if it's in the formula, it's a safety-substantiation and labeling consideration (and drives "formaldehyde-free" claims). But a hardener stays a cosmetic as long as it doesn't claim to treat a nail disease; a "treats" claim would push it to a drug.
9. What is the cosmetic (MoCRA) path for nail polish?
Register the manufacturing facility with FDA (via Cosmetics Direct, with an FEI, and a U.S. Agent if foreign), list each product/shade, designate a Responsible Person, maintain safety substantiation, set up adverse-event reporting, and use compliant labeling. For nail polish, add a color-additive review (approved colors, certified batches) and screen the formula for the toxic-trio/MMA issues. Facility registration renews every two years and listings update at least annually.
10. Do I list every shade of nail polish?
Listing is at the product level, and different shades usually differ in formulation (different color additives), so a multi-shade collection generally needs the shades reflected in the listings. A single listing submission can cover multiple products that differ only in color, which helps a large shade range, but the listing must accurately represent what's marketed and the color additives used. Registering the facility but not listing all the products is a common gap.
11. What safety data does a nail polish need?
MoCRA requires adequate safety substantiation for every cosmetic. For nail polish, the focus areas are the solvents and plasticizers (the toxic-trio ingredients and their replacements), the color additives, and sensitizers - plus stability. Given the ingredient scrutiny in this category and the exposure concerns for nail technicians, a solid toxicological/ingredient safety file matters, and the records must be available to FDA.
12. Do foreign nail polish brands need to register?
Yes. Any nail polish marketed in the U.S. must comply regardless of where it's made, and foreign facilities need a U.S. Agent. A foreign nail polish (cosmetic) registers under MoCRA with a U.S. Agent; a foreign nail product making a treatment claim (a drug) registers as a drug establishment with a U.S. Agent. Imported nail products should be screened for color-additive compliance and for MMA/toxic-trio issues before entering the U.S.
13. Does "non-toxic" or "clean" nail polish still need to comply?
Yes. "Non-toxic," "clean," "natural," and "X-free" are marketing terms that don't change regulatory status or create an exemption. A "clean" nail polish is still a cosmetic under MoCRA and needs registration, listing, safety substantiation, and compliant labeling - and its "free-of" and "non-toxic" claims must be truthful and substantiated. These terms describe positioning, not compliance.
14. What labeling does nail polish need?
Cosmetic labeling: a Principal Display Panel (statement of identity, net quantity) and an information panel (INCI ingredient declaration including color additives, responsible-party name/address, any required warnings, and the MoCRA adverse-event contact) - with no drug claims and no "FDA Approved." "Free-of" and "non-toxic" claims must be accurate. A nail-treatment drug product would need a Drug Facts panel instead. The label must match the classification and formula.
15. Does registering my nail polish mean it's FDA-approved?
No. FDA doesn't approve cosmetics (the color additives in them are separately approved, but the finished polish isn't). Registration and listing make you compliant and put your facility and products in FDA's system - they aren't approval or an endorsement. Calling a nail polish "FDA-approved" because it's registered is misleading. The accurate statement is that your facility is registered, your products are listed, and your color additives are approved for their use.
