Are there endocrine disruptors in your clothing?

Endocrine disruptors are chemicals that interfere with your hormonal system, and several of them are commonly found in conventional clothing. Phthalates used to soften plastic prints, bisphenol A (BPA) found in some synthetic fibers, antimony trioxide used as a catalyst in polyester production, and certain azo dyes are all known or suspected endocrine disruptors that have been detected in everyday garments.

These chemicals can migrate from fabric to skin through direct contact and sweat. The endocrine system regulates metabolism, growth, reproduction, sleep, and mood, so even low-level chronic exposure is a concern. Research has linked endocrine-disrupting chemicals to thyroid disorders, fertility issues, early puberty, weight gain, and hormone-sensitive cancers. Children and pregnant women are considered especially vulnerable populations.

The simplest defense is choosing clothing made from certified natural fibers with transparent supply chains. OEKO-TEX Standard 100 and GOTS certifications test for a wide range of endocrine-disrupting substances. On ONDU, brands like Organic Basics and Mate the Label hold these certifications and build their collections around organic cotton, Tencel, and other fibers that do not require the chemical processing that introduces endocrine disruptors in the first place.
