Which nail polish should a pregnant woman choose?

Pregnancy can be a frustrating time for a woman as she sees her range of possible activities diminish over the months. The same applies to cosmetics. Some contain active ingredients that pose a risk during pregnancy. Nail polishes are no exception and their use by pregnant women is often discouraged.

Indeed, most "traditional" nail varnishes contain substances that are toxic to the foetus when inhaled. Once these substances are present in the mother's bloodstream, they can easily reach the placenta. It's worth noting that the blood circulation between the mother and child is established as early as the fourth week of pregnancy.

Among the main substances found in nail varnishes that are not recommended for pregnant women, we can mention the formaldehyde. It is classified as a "possible carcinogen for humans" in Europe and is considered a potential endocrine disruptor. As a reminder, an endocrine disruptor is a substance capable of disrupting hormonal function.

We also frequently find toluene in nail varnishes. This irritating solvent emits an odour that can exacerbate nausea in pregnant women. Moreover, a recent study has correlated high exposure to toluene during pregnancy with the birth of a baby suffering from hydranencephaly, a severe brain abnormality. While the researchers themselves are not entirely certain of the established link between toluene and the disease, it is preferable in such situations to apply the principle of caution.

Finally, the following substances found in nail varnishes are also not recommended for pregnant women: phthalates, formaldehyde, parabens, camphor, benzophenone, xylene, styrene and rosin.
