Citric Acid Anhydrous Description & Feature
Anhydrous citric acid is supplied by our factory. As a professional manufacturer, we offer bulk wholesale. Highly pure and water-soluble, it can adjust acidity and cleanse stains. It is used in the food, pharmaceutical, and other fields to meet flavoring and cleaning needs. We provide efficient solutions for suppliers, distributors, and other clients, ensuring product quality and stable supply.
High Purity and Stability: Purified through advanced processes, it boasts exceptional purity and stable properties in a variety of environments. For example, when added to food and beverages, it maintains its acidity-adjusting and flavor-enhancing properties over time, resisting deterioration due to temperature and humidity. It also resists decomposition or reactions with other substances during storage, ensuring consistent and reliable product quality.
Strong Acidity and Effective Cleaning: Its rich, acidic flavor and strong acidity excel in cleaning, quickly breaking down scale and stains. Whether it’s limescale on kitchen kettles and sinks, stains on bathtubs and toilets, or even stains inside appliances, anhydrous citric acid effectively removes them. For example, it can be used to clean coffee stains from the inside of a coffee machine, leaving it looking brand new with a simple application.
Excellent Water Solubility: Its unique chemical structure makes it highly soluble in water, dispersing quickly and evenly in solutions without precipitation or residue, and preventing secondary contamination of contact items. In the food industry, it dissolves quickly when used to mix beverages, ensuring a uniform taste. In the water treatment industry, it acts as a pH regulator, quickly taking effect and precisely controlling the pH of water.
Environmentally safe and environmentally friendly: As a natural organic acid, it is harmless to humans and the environment. In the food industry, it is widely used in food and beverage processing, such as as an acidifier in juices and jams. Its high safety and compliance with food-grade standards ensure consumers can consume it with confidence. Compared to traditional chemical cleaners, its use in cleaning products reduces environmental pollution and produces no pungent odor, protecting user health.
Versatile: In the food industry, it can be used as an acidity regulator, preservative, freshness enhancer, and antioxidant synergist. In the pharmaceutical industry, it is used as an excipient in pharmaceutical preparations and as a cleaning agent for medical devices. In the cosmetics and daily chemical industry, it adjusts product pH and enhances the foaming properties of detergents. In the textile industry, it is used as a dyeing auxiliary. In water treatment, it is used to adjust water pH and reduce water hardness. Taking cosmetics as an example, adjusting the pH value in skin care products to make them more suitable for the skin’s weakly acidic environment can help the skin absorb nutrients and enhance the cleansing effect of products such as shampoo.

Citric Acid Anhydrous Applications
Anhydrous citric acid is an anhydrous form of an organic acid with a strong acidic taste, good water solubility, and chelating ability. It is widely used in various industries. The following are its main applications:
1. Food Industry
Acidity Regulator: Used to adjust the pH of foods and enhance the sourness. It is commonly found in beverages (such as carbonated drinks and juices), jams, jellies, and candies, enhancing flavor and extending shelf life.
Antioxidant Booster: Combined with antioxidants (such as vitamin C), it delays oxidative deterioration in foods and protects their color and nutrients (for example, preventing browning in canned fruit).
Chelating Agent: Binds metal ions (such as calcium and iron) in foods to prevent them from affecting texture or flavor (for example, preventing precipitation in beverages).
Fermentation Aid: During the fermentation process of bread, wine, and other products, it regulates the acidity of the fermentation environment and promotes yeast activity.
2. Pharmaceutical Industry
Pharmaceutical Excipient: Used as an acidifier or flavoring agent in tablets and granules to improve the taste of drugs (such as certain oral solutions) or stabilize drug ingredients (for example, preventing the deterioration of hydrolyzed drugs). Cleaning agent
ingredients: Used for disinfecting and cleaning medical devices, utilizing its acidic and chelating properties to remove scale, stains, and microorganisms.
3. Daily Chemicals and Cosmetics
Skin Care Products/Shampoos: Adjust the pH of the product to more closely resemble the slightly acidic environment of the skin or scalp, while also enhancing the detergent’s foaming properties.
Metal Cleaners: Remove rust and scale from equipment surfaces by chelating metal ions, commonly used in industrial cleaning.
4. Other Industrial Uses
Textile Industry: Used as a dyeing auxiliary to help dyes adhere evenly to fibers and enhance dyeing results.
Water Treatment: Used to adjust water pH or bind with metal ions to reduce water hardness.
Citric Acid Anhydrous Specifications
As a high-quality raw material, citric acid offers significant benefits. In the food industry, it can precisely adjust the acidity of beverages, jams, and other products, imparting a refreshing and palatable flavor.
