Magnesium stearate is a white, odourless powder that can be used as a lubricant and flow agent in toothpaste tablets. It is derived from a combination of magnesium and stearic acid, which are produced from mineral and plant sources.

In toothpaste tablets, magnesium stearate helps to ensure that the ingredients are evenly distributed and well-mixed, while also preventing the tablet from sticking as it is compressed during the manufacturing process.

Magnesium stearate is biodegradable and is also approved for use in food products by regulatory agencies around the world. When combined with other ingredients, such as baking soda, and essential oils, this ingredient helps to create a gentle and effective toothpaste.
