Sodium Bicarbonate is a cosmetic formulation aid commonly used as an alkalising and buffering agent, helping to adjust and maintain pH in bath and body products.
It is also widely used in effervescent formulations, where it reacts with citric acid to create the characteristic fizz in products such as bath bombs and bath melts.
Sodium Bicarbonate is supplied as a fine, free-flowing powder suitable for use in cosmetic formulations.
