ReAgent Are Leading Citric Acid Suppliers

Citric acid is a weak organic acid that is naturally found in citrus and juicy fruits such as lemons, limes, oranges, grapefruit, apples, pears, and berries. Although it is often associated with sweet-tasting fruit, citric acid appears as odourless and colourless crystals.

The properties of citric acid are as follows:

  • Appearance: Solid
  • Formula: C6H8O7
  • Melting point: 153°C
  • Boiling point: 175°C
  • Density: 500-950 kg/m3 CAS No.: 77-92-9

At room temperature, citric acid is a white crystalline powder in either anhydrous or monohydrate forms. Monohydrate citric acid can be easily dried by heating the crystals at 78°C, but higher temperatures will result in decarboxylation. This compound can dissolve in water, ethanol, ether, DMSO, and other solvents.

Citric acid has many uses across various sectors, from the food, pharmaceuticals and cleaning industries to the cosmetics, agriculture, and even biotechnology industries. Here is an overview of its most popular uses:

  • A flavour enhancer and preservative in food and beverages
  • An excipient in the formulation of medicines
  • A component in eco-friendly cleaning products, like detergents
  • A precursor to various chemicals used in the production of other compounds

Applications of Citric Acid

Citric acid is a versatile compound that finds applications in various industries due to its unique properties. Some of its key characteristics include acidity, chelation (ability to bind to metals), and being a natural preservative. This allows it to be used in many diverse ways:

  • Flavour enhancer and acidifier. It is widely used in the food and beverage industry to improve flavour or add acidity to drinks, candies, jams, and other processed foods
  • Preservative and emulsifier. Citric acid is also used as an emulsifying agent in things like cream. It also improves the stability and extend the shelf life of foodstuffs
  • Excipient in the formulation of medicines by the pharmaceutical industry. It is used to adjust the pH of solutions, enhance the bioavailability of certain drugs, and act as a stabilising agent in liquid medications
  • Component in cleaning products. The chelating properties of citric acid help to remove mineral deposits and prevent staining in hard water
  • Personal care products. It is used in shampoos, soaps, lotions, etc., as a pH adjuster, chelating agent, and as a way to promote exfoliation in skincare formulations
  • Agricultural practices. In agriculture, citric acid helps to create a mildly acidic environment that facilitates certain agricultural treatments. It can be employed to adjust the pH of soil, making it more suitable for certain crops
  • Chelating agent in water treatment. Here, citric acid is used to remove metal ions and prevent scaling in pipes and equipment
  • Key bath bomb ingredient. Citric acid is crucial to the signature fizz of bath bombs, where it reacts with the baking soda to release carbon dioxide
  • Textiles and photography. It is used in the dyeing process of textiles to regulate the pH levels and improve the colour fastness of certain dyes. It is also used in photographic development to neutralise alkaline developing solutions
  • Precursor to various chemicals. Citric acid is used in the chemical industry as a precursor to chemicals and intermediates used in the production of other compounds, such as acetic acid and citrate salts
  • Citric acid fermentation. In biotechnology, citric acid fermentation is a widely used method to produce citric acid on a large scale. The process involves using certain strains of fungi, such as Aspergillus niger, to produce citric acid from sugar sources

The range of citric acid formulations ReAgent manufactures meet a variety of application needs. Our anhydrous citric acid, for example, is well-suited for chemical processes with water-sensitive reactions, as well as for ensuring consistent results in pharmaceutical formulations with moisture-sensitive ingredients.

Meanwhile, our citric acid 20% w/v is ideal for cleaning products, rust removal, pH adjustment, chemical processes, and so on. The high purity of our citric acid products, combined with our ability to create bespoke blends, ensures that we’re able to supply you with the best product for your specific application needs.

Storing Citric Acid: Guidelines

Although it is a weak acid, citric acid can cause adverse effects in humans if inhaled or ingested in large, concentrated quantities over a long-term period. It is crucial that all storage guidelines are properly adhered to when handling this product.

To safely store citric acid, follow these guidelines:

  • Use an airtight container made of glass, plastic, or metal
  • Given its hygroscopic nature, store it in a dry location away from liquids
  • Keep away from direct sunlight and store in a cool area with stable temperatures
  • Clearly label the container with the contents and date of storage
  • Store away from incompatible substances, like strong oxidizers or alkalis
  • Choose a location inaccessible to children and pets to avoid accidental exposure
  • Ensure proper ventilation, especially when handling large quantities of citric acid
  • Wear appropriate safety gear, like gloves and goggles, to protect your skin and eyes

For more information, always ensure to follow the MSDS for the specific product. You can find this here for our anhydrous citric acid and here for the 20% w/v formulation.
