You can get irritation from ingredients that are used to make the soap, for example I can't use pure glycerin soaps or soaps with high glycerin content, or glycerin to slicken up lather if I wanted. To eliminate the scent part of the problem go for unscented if you can or something that has no citrus or patchouli in it.
