Citric acid is available in Monohydrate and Anhydrous forms — chemically identical in acidity and
reactivity, but differing in stability and moisture content.
The Monohydrate form is stable in humid air, while the Anhydrous form is better suited for dry or
moisture-sensitive applications. This distinction makes citric acid versatile across varied
processing
needs, from food and beverages to pharmaceuticals, personal care, and heavy industry.
