What is Magnesium Aluminum Silicate and why does Weleda use it?
A. Magnesium Aluminum Silicate (Fuller’s Earth) is a naturally occurring mineral. Its name is the standard label applied to natural earth of various origins. Other commonly known names for this ingredient are Hectorite, Kaolin and White Clay. This clay serves as a natural thickener commonly used to hold ingredients together, providing a moisture-binding effect. The molecules of Magnesium Aluminum Silicate are too large to be absorbed through the skin, and it is a dermatologically well-tolerated material. This clay helps to remove impurities from the skin in Weleda’s body care formulations and works as a gentle polisher in Weleda’s toothpastes.
