What It Does
Sodium Bicarbonate is a white crystalline alkaline salt that occurs naturally in mineral deposits or is synthetically produced. In cosmetics, it serves as a gentle pH buffer to neutralize acidic formulations, provides mild physical exfoliation in scrubs and cleansers, and offers deodorizing properties by neutralizing odor-causing acids. Formulators value it for its multifunctionality, safety profile, and ability to create effervescent reactions when combined with acids, making it popular in bath bombs and fizzing products.
