Description

Citric Acid Monohydrate is the hydrated crystalline form of a key organic acid found naturally in citrus fruits, widely recognized for its versatility as a safe and effective acidulant, chelating agent, and pH buffer. Its importance stems from its GRAS (Generally Recognized As Safe) status, biodegradability, and multifunctional properties, making it indispensable across numerous industrial and consumer sectors. This product is essential for manufacturers in the food and beverage, pharmaceutical, personal care, and industrial cleaning industries seeking a reliable, high-quality ingredient.

Application

• Food & Beverage Industry: Primary use as an acidulant and flavor enhancer in soft drinks, candies, jams, and preserved foods; also acts as a preservative and antioxidant synergist.
• Pharmaceuticals: Used as an excipient in effervescent tablets and powders, a pH adjuster in syrups and elixirs, and a chelating agent in formulations.
• Personal Care & Cosmetics: Functions as a pH adjuster, antioxidant, and chelator in creams, lotions, and hair care products; key ingredient in bath bombs and effervescent products.
• Industrial Cleaning & Detergents: Effective chelating agent in liquid and powder detergents, descaling agents, and metal cleaners due to its ability to bind hard water ions.
• Water Treatment: Employed to inhibit scale formation and for chelation of metals in boiler and cooling water systems.
• Technical & Chemical Synthesis: Serves as a starting material or intermediate in various chemical processes and as a biodegradable builder in eco-friendly formulations.

Quality Control

Our Citric Acid Monohydrate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We offer grades compliant with major international pharmacopeial and food standards, including USP-NF, FCC, BP, Ph. Eur., and JP. Every batch undergoes rigorous analytical testing, and a comprehensive Certificate of Analysis (COA) documenting purity, identity, and safety parameters is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption. Keep away from incompatible materials such as strong bases, oxidizing agents, and nitrates.
