That is a good point. Even some premium shaving soaps and creams contain Tartrazine, noted either by name or shown E102, especially for lemon or citrus scented soaps.This used to happen to me until i switched to unscented shaving soap.
Best change i ever made!
This can cause a severe reaction with some people, including me.
If ingredients are not not listed or available from the makers and the soap/cream is lemon or citrus scented then I have to put it back on the shelf.
