Sodium Bicarbonate



No known benefits

Sodium Bicarbonate description

A synthetic inorganic salt more commonly known as baking soda. It has many functions in cosmetics, including pH adjuster, buffering agent, and abrasive, such as in face or body scrubs. When used in small amounts to adjust and maintain the pH of cosmetic products, baking soda is not a problem for skin; however, when used among the main ingredient in scrub products, it’s simply too abrasive and an ingredient we don’t recommend. The rating for this ingredient pertains to its benefit as a pH adjuster and buffering agent.
