SODIUM SESQUICARBONATE

Safety grade: A

Sodium sesquicarbonate is a mild alkaline salt that's similar to baking soda but slightly different in chemical composition. It's commonly used in cleaning products and personal care items because it's gentler and more stable than regular baking soda.

This ingredient balances the pH level of cosmetic formulas to keep them from being too acidic, adds thickness or body to products, and helps remove dirt and oil from skin.
