Citric Acid Monohydrate - USP Food Grade

Why Citric Acid Monohydrate - USP Food Grade

Citric Acid Monohydrate - USP Food Grade is a highly soluble, translucent crystalline powder selected when strict regulatory compliance for human consumption, pharmaceutical formulation, or cosmetic manufacturing is mandatory. By sourcing the dry monohydrate chemical structure (CAS: 5949-29-1, C6H8O7·H2O), facility operators and formulation chemists gain absolute control over batch concentration parameters while eliminating the heavy shipping weights associated with pre-mixed aqueous solutions. The USP Food Grade classification guarantees the exacting purity levels necessary for direct food contact applications, ensuring the material is free from harmful heavy metals and unapproved byproducts. With a flash point of 385 degrees Fahrenheit, this crystalline acid dissolves rapidly in water and maintains moderate solubility in alcohol, making it an efficient, predictable raw material for high-volume aqueous processing where exact pH buffering is critical.

Best Applications for This Grade

• Food and Beverage Acidulation: Commonly applied in commercial beverage production, jellies, and canned goods to strictly lower the pH and establish a stable, tart flavor profile. The precise translucent crystal allows for exact weight-based measurement to inhibit microbial growth and extend product shelf life without altering the intended texture or appearance.
• Pharmaceutical Formulations: Utilized extensively as an active effervescent agent, reliable chelator, and strict pH buffer in liquid medicines, syrups, and chewable tablets. Sourcing a USP-certified product ensures the raw material satisfies the rigorous safety, purity, and traceability mandates enforced by pharmaceutical regulatory bodies.
• Cosmetic pH Adjustment: Commonly applied in commercial lotions, facial serums, and bath formulations to stabilize volatile active ingredients and maintain a skin-safe pH environment. The moderate alcohol solubility and rapid water solubility allow cosmetic chemists to integrate the acid into complex emulsion systems without risking phase separation.
• Nutraceutical Processing: Acts as a dependable chelating compound in dietary supplements to enhance the human bioavailability of essential minerals like calcium and magnesium, while maintaining complete adherence to strict food-grade manufacturing compliance.

When to Choose a Different Grade

• If an operation specifically requires a highly concentrated, ready-to-use liquid format for continuous pH dosing without the mechanical labor of dissolving a dry powder, evaluate Citric Acid 50% Solution.
• If a facility requires a moderately concentrated, pre-mixed liquid for immediate fluid adjustment and scaling removal, select Citric Acid 25% Solution.
• If formulating an anhydrous product where the single water molecule present in the monohydrate lattice (C6H8O7·H2O) could trigger premature effervescent reactions or clumping, an anhydrous crystalline grade must be sourced instead.
• If the end-use involves heavy-duty industrial metal passivation or municipal wastewater treatment where USP Food Grade purity is not a regulatory necessity, procuring a standard industrial-grade acid will meet operational requirements more economically.
