Anhydrous Citric Acid

Anhydrous Citric Acid is a white crystalline powder composed of a natural organic acid with the chemical formula C6H8O7. It is supplied in a dry, free-flowing form, typically at a purity of 99.5% or higher, making it suitable for precise industrial applications requiring consistent acid strength. The compound is highly soluble in water, dissolving rapidly to provide effective pH control and metal ion chelation. The product is commonly used in dosages ranging from 0.1% to 5% w/v depending on the application, such as water treatment or formulation of pesticides. It should be stored in a cool, dry place away from strong oxidizers and moisture to maintain stability and prevent caking. Users should handle it with appropriate protective equipment as it is acidic and may cause irritation upon contact. Anhydrous Citric Acid’s acidity typically leads to an aqueous pH between 2 and 3 when dissolved, enabling its role as a reliable acidulant and chelating agent in industrial processes. Its compatibility with various formulation ingredients is well established, but it should not be mixed directly with strong oxidizing agents during storage or handling due to risk of reaction.

In water treatment, scale buildup from calcium and magnesium deposits reduces the efficiency and lifespan of pipelines and equipment. Anhydrous Citric Acid addresses this by chelating these metal ions, preventing scale formation and thereby sustaining optimal flow and reducing maintenance downtime. In agrochemical formulations, it enhances the solubility and stability of active ingredients, improving product effectiveness and shelf life. This precise pH adjustment and metal ion control play critical roles in maintaining the performance characteristics tailored to specific industrial needs, reducing waste and improving process reliability.
