The toothpaste tastes very good and my teeth were really smooth to use, but what bothers me (solid) is sodium lauryl sulfate. I then googled Internet, because I've heard nothing good about sodium laureth sulfate. The suspicion was confirmed. Sodium Lauryl Sulfate is actually pretty much the same as sodium laureth sulfate, and also the effect it in the organs deposit (Yes, that leads to it disease-GoogleT just once), mucous membranes, skin etc. irritates itself. Otherwise, it is like saying good in terms of taste, cleaning and lather it also does well because of that damn sodium lauryl sulfate xD
