Anhydrous citric acid (CAS No. 77-92-9) is a staple in industries where moisture control is critical-and our product is engineered to deliver exceptional stability, solubility, and performance in even the driest environments. Unlike monohydrate citric acid, which contains 8.5-10.5% water of crystallization, our anhydrous variant is completely free of water (moisture content ≤0.5%), making it ideal for applications where water could compromise product quality, such as low-humidity manufacturing facilities, powdered formulations, or long-term storage in arid regions.
Our anhydrous citric acid is a white, odorless crystalline powder with excellent solubility: it dissolves quickly in water (133g/100mL at 20°C) and ethanol (23g/100mL at 20°C), ensuring easy integration into liquid and semi-liquid formulations. We've optimized its particle size distribution (90% passing through 100 mesh) to enhance flowability-preventing clumping and ensuring uniform mixing in dry blends. This is particularly important for food processing applications, such as powdered drink mixes, cake mixes, and spice blends, where consistent texture and flavor are key. For example, in instant coffee or hot chocolate mixes, our anhydrous citric acid dissolves evenly, adding a subtle tartness that balances sweetness without leaving gritty residues.
In industrial applications, its low moisture content makes it a reliable choice for detergent powders and cleaning agents. Unlike monohydrate citric acid, which can absorb moisture and clump in dry detergents, our anhydrous variant remains free-flowing, ensuring each scoop contains a consistent amount of active ingredient. It also enhances the cleaning power of detergents by softening water and breaking down grease and mineral deposits. In cosmetic formulations, such as powder blushes, eyeshadows, or dry shampoo, it acts as a pH adjuster and texturizer-improving product stability and application.
Quality control is a top priority for our anhydrous citric acid. Every batch undergoes testing for purity (≥99.5%), melting point (153-159°C), and heavy metal content (lead, cadmium, mercury ≤0.1 ppm) to meet industry standards (FCC, USP). We offer flexible packaging options: 25kg polyethylene bags with inner moisture-proof liners (for small to medium orders) and 1000kg bulk bags with polyethylene liners (for large-scale production). For customers in high-humidity regions, we also provide vacuum-sealed packaging to further protect against moisture absorption. With a production capacity of 3,500 tons per month, we can fulfill orders of any size-from 1kg samples for product testing to 100-ton bulk shipments-with delivery times of 5-10 days to major global ports.
