Description
Sodium bicarbonate (CAS 144-55-8) is an inorganic salt commercially known under names including Soludal and soda mint, and commonly abbreviated as NaHCO3. It carries no E-number designation but meets food-grade and pharmaceutical monograph standards across multiple regulated markets.
In pharmaceutical manufacturing, sodium bicarbonate acts as a buffering agent by accepting or donating protons to stabilise formulation pH within a defined range. In water treatment, it neutralises acidic effluents through controlled alkalinity adjustment. In personal care, it functions as a skin conditioner and mild antimicrobial by disrupting microbial membrane integrity at elevated pH.
Sodium bicarbonate is available in food-grade (FCC), pharmaceutical-grade (Ph.Eur.), and technical-grade forms, supplied as a white powder or as a 7.5% aqueous solution. The substance is registered under REACH and classified under HS code 28363000. Standard packaging includes 25 kg bags, big bags, and bulk delivery options.
