The philosophy of Gioganics is very simple. By using only natural ingredients in all of our dental care products, we avoid synthetic chemicals that can have a negative impact on both health and the environment. Instead of synthetics like glycerin or sodium lauroyl sulfate (SLS), opt for mineral-rich ingredients such as calcium, potassium, and natural clay. They also use oils such as organic coconut oil, which acts as a natural preservative. As a member of 1% for the Planet, we are committed to contributing to the environment. As a member, we donate more than 1% of our sales to various non-profit organisations (NPOs).
