I would say that it's my right to have the guarantee that there is no hydrochloric acid in a hygiene product, especially one that can get near sensible parts of the body like your face and your eyes. Sane adults can blame someone when they buy a product whose properties do not match those of what the product is supposed to be.

It may be your right to buy hydrochloric acid and to pour it over your head, but actually, that's wildly different to what you said.
