Core Functions & Main Applications

1. Food & Beverage Industry (Core Application)

• Acidulant: Adjusts acidity and enhances fresh sour flavor for fruit juices, carbonated drinks, candies, jellies, pickles and dairy products.
• Preservative & Antistaling Agent: Inhibits microbial reproduction, prolongs food shelf life and reduces the use of synthetic preservatives.
• Chelating Agent: Complexes metal ions in food, prevents oxidative discoloration and quality deterioration, maintains product color and taste.

2. Daily Chemicals & Cosmetics

• Skin care & Hair care products: Regulates product pH value, stabilizes formulations, has mild exfoliating and moisturizing auxiliary effects; no irritation to human skin.
• Detergents: Serves as a phosphorus-free chelating agent, softens water by complexing Ca²⁺/Mg²⁺ ions, improves decontamination efficiency and reduces scale formation.

3. Pharmaceutical Industry

• Pharmaceutical excipient: Adjusts the pH of drug preparations, acts as the acid source for effervescent tablets (reacts with sodium bicarbonate to produce CO₂).
• Medical cleaner: Used for mild cleaning of medical devices, non-corrosive to equipment and has a certain bacteriostatic effect.

4. Industrial Manufacturing & Water Treatment

• Water treatment: Acts as a water quality stabilizer and chelating agent, removes heavy metal ions from industrial wastewater, prevents scaling in pipelines and equipment.
• Electroplating industry: Regulates electroplating bath pH, improves the uniformity and smoothness of plating layers as a complexing agent.
• Textile printing & dyeing: Serves as a color fixative and buffer, improves dyeing effect and prevents dye hydrolysis.

• Plastic & rubber: Auxiliary raw material for antioxidants and plasticizers, enhances the chemical stability of products.

Chemical Classification & Industrial Attribute

Citric Acid Monohydrate is a typical fine organic chemical product, classified as a food additive, industrial auxiliary and pharmaceutical excipient in different application fields. It is mainly produced by microbial fermentation technology (a classic organic chemical production process), with strict industrial quality standards and detection indicators. As a multi-purpose general chemical, it crosses food, daily chemical, pharmaceutical, industrial and environmental protection fields, and is a key fine chemical raw material with broad application prospects.
