MAGNESIUM SILICATE

Safety grade: A

Magnesium silicate is a naturally occurring mineral powder that absorbs moisture and oil. It's commonly used in dry products like powders and foundations to keep them from clumping and to make them feel smooth and dry on the skin.

This ingredient absorbs excess oil and moisture, prevents clumping in powder products, adds volume and thickness, and creates an opaque finish while controlling how thick or thin a product feels.
