Nail polish is a go-to cosmetic for adding beauty and personality to your nails, but applying it well takes more than a steady hand.
To achieve a polished, professional look at home, it helps to understand the basics—from ingredients to proper application techniques.
What’s Inside Your Nail Polish
Nail polish contains a mix of chemicals that give it color, shine, and durability. Some are generally safe in small amounts, while others raise health and environmental concerns, especially with repeated exposure.
Key Components:
- Film-forming agents like nitrocellulose provide the shiny, solid coating.
- Plasticizers and resins help polish stay flexible and resist chipping (e.g., camphor, TPHP), though some may irritate or disrupt hormones.
- Solvents such as ethyl acetate make the polish spread easily and dry fast but can be irritating in unventilated areas.
- Pigments and colorants offer the desired shades and effects; glitters, however, may contain non-biodegradable microplastics.
- UV stabilizers like benzophenone-1 prevent fading but may act as endocrine disruptors.
Ingredients to Avoid:
Some ingredients in conventional nail polish have been linked to health risks. These include:
- Formaldehyde and its resin – carcinogenic and allergenic
- Toluene – affects the nervous system
- DBP (dibutyl phthalate) – linked to reproductive issues
- TPHP – suspected hormone disruptor
- Parabens, camphor, ethyl tosylamide, xylene – potential irritants or banned in some places
Many brands now promote “X-Free” labels, such as 5-Free, 7-Free, or 10-Free, indicating how many of these chemicals they exclude. Safer options include polishes with mineral pigments, biodegradable glitter, and preservatives like phenoxyethanol.
