Most of the commercial toothpastes contain sodium lauryl sulfate (SLS), a foaming agent that was originally used in shaving cream. Many brands are now reformulating their formulas to avoid SLS.
In spite of the popularity of SLS, there is still controversy about its safety. Some scientists believe that it can cause cancer. This belief is based on animal studies. It appears that SLS can cause cancer when it is exposed to the lungs, especially if it is breathed in for a long period of time. In addition, if SLS comes into contact with the skin, it can irritate and dry the skin. This can lead to eczema and psoriasis. There is also evidence that SLS can cause allergic reactions in some individuals.
As well as the possible effects of SLS, most of the other Vegan toothpaste ingredients found in conventional toothpaste may have potential health issues. For example, many mainstream brands use artificial colors and dyes. It has been found that these colors have hormone-like properties. They have also been linked to developmental disorders. As well as this, many of these ingredients are potentially harmful. They include triclosan and sodium bicarbonate. These substances are widely used in mainstream toothpaste. This is because they are known to reduce plaque and prevent cavities.
