Non-Bio detergents contain surfactants specifically for the purpose of removing sweat. If your clothes are still smelly, try a different brand, cos yours isn’t working properly.
Edit, using some Wikipedia knowlage it turns out that you can’t be alregic to bio washing powder. So either Wiki is wrong or my missus can gain a nocebo effect even when she doesn’t know I’ve used the wrong powder, she’d start itchng as soon as she used a towel that’d been washed in bio stuff.
