I got two children with eczema and allergies and my DD is known to react to Ecostore's products including washing powder/liquid. Is your child allergic to peanuts/tree nuts? that is main reason behind few people know to react to Ecostore because it used coconut/palm oil.
I am currently trying new washing liquid by Mela power by ecosense BUT my DS2 got unexplained eczema flare up and I just realize now I have switched washing liquid recently
So that might be another one go into bin?....argh!
For eczema, have you tried pure shea butter?
