What It Does

Citric Acid, Aqua is a 20% aqueous solution of citric acid, a naturally occurring alpha-hydroxy acid (AHA) produced through fermentation of carbohydrate sources. This pre-diluted format offers formulators precise pH control and chelating capabilities without the handling challenges of anhydrous citric acid crystals, making it particularly valuable for adjusting pH in water-based formulations while simultaneously binding metal ions that could destabilize products. The aqueous solution form ensures easier dispersion and more consistent results in cold-process formulations compared to dissolving crystalline citric acid.
