Is it safe to use endosulfan-treated cotton clothing imported from overseas?
No. Endosulfan is banned but still used overseas. Residues reach consumers on cheap textiles.
What's actually in it
Endosulfan is a persistent organic pollutant that was banned globally under the Stockholm Convention. Despite the ban, some regions still use it illegally on cotton crops. Cotton grown with endosulfan retains residue through processing, and the residue can transfer to skin during wear. Cheap imported fast-fashion cotton (especially from unregulated supply chains) has been found with detectable endosulfan.
Endosulfan is a neurotoxin and reproductive toxin. Chronic low-dose exposure through skin is a real concern.
What the research says
A 2026 review in Toxicol Ind Health detailed the reproductive toxicity of endosulfan, including mechanisms affecting both male and female reproductive health. The chemical disrupts hormone pathways, damages reproductive cells, and crosses biological barriers. The exposure route through consumer textiles is one of several pathways.
For cotton clothing, choose organic cotton from brands with GOTS certification (Pact, Boody, Kotn, Colored Organics). These brands use pesticide-free cotton. For fast fashion, washing new clothes twice before wearing removes a lot of surface residue. Skipping bulk imports of cheap cotton basics from unknown brands is a reasonable rule. The premium for organic cotton is small compared to the health consequences of repeated skin exposure.
