Most people assume that a foam is necessary when brushing their teeth. However, equating foaminess with cleanliness is all in your mind - put there by years of shampoo commercials showing people having the time of their lives while washing suds out of their hair. The truth of the matter is that foam is typically caused by chemicals! Sodium Lauryl Sulfate is one of the most common foaming agents added to dental products. These nasty chemicals are added to your shampoo or toothpaste just to make it foam. It’s not necessarily cleaning any better, it’s just making you think it is. Now don’t get us wrong, there are also natural ways to make foam but those products (like our toothpaste) will have low foam. A super frothy lather is most likely chemically induced. When we were formulating our organic toothpastes, we thought a lot about foam. It goes without saying that we would never include any chemicals, but we did think about the fact that people like foam because it makes them feel cleaner. It may be a mindset, but it’s a mindset that people enjoy, and we’re all about adding joy to the mundane tasks of daily life. We researched many different natural and organic foaming ingredients and ultimately decided on Quillaja Saponaria Wood Extract - a mouthful to say, we know! It causes a low, natural foam and is completely safe. This extract has a long history of medicinal use with Andean people, who used it especially as a treatment for various chest problems.
