Are laundry detergents safe for washing baby clothes?

What's actually in it

Laundry isn't just about soap. The process of washing clothes releases microfibers from synthetic fabrics into the air and water. These tiny plastic particles are not inert. When they enter the air, they can be inhaled, leading to potential health risks for your baby.

Furthermore, many conventional laundry products contain persistent organic pollutants and endocrine-disrupting chemicals. These substances are known to interfere with your body's hormone systems. Because babies are still developing, they are especially vulnerable to these chemical exposures that can disrupt normal biological functions.

What the research says

The science is clear that the laundry cycle is a source of hidden hazards. A 2026 study in Environ Res found that repeated airway exposure to washing-machine lint microfibers can cause lung inflammation. This inflammation may be linked to dysfunction in how cells clean themselves, which could even affect how your DNA replicates.

Additional peer-reviewed research highlights the danger of these particles in the lungs. A 2026 study in Ecotoxicol Environ Saf shows that microplastics drive specific immune cell functions that lead to allergic airway inflammation. This means the very act of washing clothes can create an environment that irritates the respiratory system.

Finally, the chemicals often found in laundry additives add another layer of risk. A 2026 study in Ecotoxicol Environ Saf analyzed US population data and confirmed that combined exposure to persistent organic pollutants and endocrine-disrupting chemicals is linked to an increased risk of thyroid disease. These chemicals don't just disappear after the rinse cycle.
