What Sodium Magnesium Silicate is & what it does

A mineral thickener used to suspend particles and stabilize emulsions, giving a smooth, creamy body. It also adds a soft feel.

What does Sodium Magnesium Silicate do in skincare?

Sodium Magnesium Silicate is used mainly as a thickening and stabilizing agent. In creams, gels, and sunscreens it helps adjust texture and viscosity and can keep other ingredients evenly suspended. It is a structuring ingredient rather than an active.

Is Sodium Magnesium Silicate comedogenic?

As a mineral silicate used to modify texture, it is not generally associated with clogging pores, though individual reactions can vary. Anyone prone to breakouts can patch test a product, since pore-clogging potential also depends on the full formula.

Is Sodium Magnesium Silicate natural or synthetic?

It is a mineral-based silicate compound. Such silicates can be sourced from natural mineral materials or manufactured synthetically, and they are typically purified or processed before use in cosmetics.
