Is It Safe to Paint Your Toddler's Nails?

For most parents, painting a toddler's fingernails and toenails seems like harmless fun; some salons even offer manicures and pedicures for children. And the idea often delights young children who love bright colors or who want new ways to express themselves (or feel a bit more grown-up). Before you paint your child's nails, though, it's worth learning a bit more about nail polish safety. Many brands contain chemicals that may affect your decision.

Toxins Found in Many Nail Polishes

Unfortunately, that pretty bottle of nail polish may be a mix of chemicals that some researchers say are potentially harmful and toxic. That amount at which they pose a concern, however, is debated.

There are four major toxins in some brands of nail polish that get the most attention:

  • Toluene is a chemical that is also used in paint thinner, artificial fragrances, cleaning solutions, and other household products. Prolonged and repeated exposure to toluene (including at work or chronically inhaling it on purpose) has been shown to damage to the liver and kidneys as well as cause nervous system problems and upper respiratory issues.
  • Triphenyl phosphate, or TPHP, is a chemical that can disrupt the endocrine system and is used to make plastics and also as a fire retardant. TPHP is found in many of today's top brands of nail polish. In 2015, a study conducted by researchers at Duke University and Environmental Working Group found a sharp increase in TPHP levels in the urine of 26 women who were tested.
  • Formaldehyde is commonly used in building materials and many household products. It acts as a hardener to prevent your nail polish from chipping. Long-term exposure can cause respiratory problems and may increase your risk of certain types of cancer. Other research, such as this study from 2015, has found that formaldehyde exposure in pregnant women is linked to spontaneous abortion, congenital malformations, and premature birth.
  • Phthalates are used in nail polish and other personal care products to provide lubrication and carry fragrances. Phthalates are known weak endocrine disruptors and androgen blocking chemicals. Some research has found associations between prenatal and childhood phthalate exposure and developmental delays and allergic diseases.

Is an Occasional Polish Really Dangerous?

There is not enough evidence to support a direct link between nail polish use and cancer, respiratory disease, or other health problems, but even still, some researchers warn of potential risk.

It's also worth noting that toddlers tend to put their pretty little fingers (and toes) in their mouths—and there's not a whole lot you can do to stop them from such behavior. Since ingestion is possible, some parents may refrain from using chemical nail polishes on toddlers entirely. Even nail polishes labeled "nontoxic" may contain toxic ingredients.

To protect your child from exposure to toxins and chemical fumes from nail polish, avoid nail salons with poor ventilation.

Safe Polish Options

Regardless of what research has shown, the buzz around this hot button topic has managed to pressure major manufacturers to revamp their ingredients. And amid growing concern from parents, some companies have developed safer polish options for little fingers and toes.

Brands like Hopscotch Kids and Piggy Paint provide water-based nail polishes and polish removers that are free of dangerous chemicals.

If you're looking at other brands of polish, you can check the Environmental Working Group's nail polish directory to see the safety rating for specific products. Each one is ranked on a scale of 0 to 10 (0 being the safest).
