Best Nail Polishes 2026 — 5-Free and 10-Free Ranking

A manicure isn't just about aesthetics — it's also a question of chemical safety. For years, classic nail polishes contained compounds with toxicological question marks: formaldehyde, toluene and DBP (dibutyl phthalate). Today, cosmetic brands compete to create 5-free, 10-free and even 16-free formulas. What do these labels actually mean in practice, and which polish is worth choosing in 2026?

What do the "free" labels mean?

The 5-free label means the polish does not contain the five most frequently criticised ingredients:

• Formaldehyde (Formaldehyde) — a preservative and hardener; classified as a Category 1A carcinogen by IARC
• Formaldehyde resin (Tosylamide/Formaldehyde Resin) — a resin produced by the condensation of formaldehyde
• DBP (Dibutyl Phthalate) — a plasticiser banned in EU cosmetics since 2003 under Regulation 1223/2009
• Toluene (Toluene) — a solvent banned in EU cosmetics (Annex II)
• Camphor (Camphor) — irritating at high concentrations; permitted in the EU up to 0.1% in nail products

It's worth stressing that in the European Union, DBP and toluene are already banned in cosmetics. A polish without these ingredients is the EU standard, not an exceptional selling point. The "free" labels carry more marketing weight outside Europe — for example in the USA, where regulations are less strict.

How do we assess nail polishes?

In our ranking we analyse the full INCI composition of every product. The key criteria are:

• Presence of plasticisers — safe alternatives to DBP (e.g. Triphenyl Phosphate — also raising concerns, vs. safer options such as Acetyl Tributyl Citrate)
• Film-forming resins — Nitrocellulose (Nitrocellulose) is the standard; increasingly being partly replaced by polymers from renewable sources
• UV stabilisers and curing properties — in gel polishes, the quality of the photoinitiators matters
• Durability and coverage — PurScore user ratings and manufacturers' clinical data

Traditional vs. gel — which to choose?

Traditional polishes

They dry in the air and are easily removed with acetone or an acetone-free remover. A well-formulated one can last 5-7 days. Their composition is usually simpler and easier to evaluate. For anyone with sensitive nails, or those who change colour often, this is a convenient choice.

Gel polishes (UV/LED)

Cured under UV or LED light, they hold for 2-3 weeks without chipping. The formula contains acrylate monomers and oligomers (e.g. HEMA — Hydroxyethyl Methacrylate), which can sensitise the skin with prolonged contact on intact skin — which is why correct application without touching the nail fold is important. In 2022 the SCCS issued an opinion on HEMA and similar monomers — used properly, the risk is low, but anyone with a confirmed allergy should take care.

What to look for in a good polish in 2026?

1. No Triphenyl Phosphate (TPHP) — a common DBP substitute, but one that itself raises concerns as a potential endocrine disruptor in in-vitro studies
2. Acetyl Tributyl Citrate (ATBC) as a plasticiser — one of the safer alternatives
3. Low VOC content — polishes with a lower content of volatile organic compounds are kinder to both the user and the environment
4. Pigments free of heavy metals — coloured polishes can contain pigments with contaminants; choose brands with certified supply chains

Caring for and conditioning the nail plate

Even the best polish is no substitute for good basic care. Visit our nail polish and nail product category regularly, where you'll also find nourishing bases and top coats with keratin, calcium and amino acids. A base coat protects the nail plate from staining and strengthens its structure.

Removing polish — what to keep in mind

Acetone dissolves nitrocellulose effectively, but it dries out the nail plate and cuticle intensively. Alternative removers based on ethyl acetate (Ethyl Acetate) or butyl acetate (Butyl Acetate) are gentler but less effective on thick layers. Always apply a cuticle oil after removing polish — jojoba or argan oil regenerate a weakened nail plate well.

With gel polishes, avoid mechanical scraping — it rapidly damages the nail surface. Use removal wraps or special higher-concentration acetones (90%+) according to the manufacturer's instructions.

Summary

In 2026, the best nail polish is one that combines durability with a safe composition — free of TPHP, with certified pigments and next-generation plasticisers. Verify the composition with the PurScore search tool to be sure you're making an informed choice.
