Citric Acid Uses



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.



Due to its ready availability, it is often found in many applications such as:




  • Food flavouring, colouring or preservation. It is also often added to products like ice cream as an emulsifying agent to stop fats from separating


  • Cleaning and chelating agents, particularly in home bathroom and kitchen cleaning products. It is also used to remove rust from steel in industry


  • Photographic development to neutralize the alkaline developing solutions


  • pH balancing for pharmaceuticals


  • Substitution of nitric acid in industry.



Production of Citric Acid



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



ReAgent sells citric acid in containers of 500g all the way up to 25kg bags. Should a smaller or larger quantity be required, please contact us. Precautions must be taken at all times when handling chemicals – please refer to this chemical’s material data safety sheet (MSDS) for full details.



Citric Acid Side Effects



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 handling and storage guidelines are properly adhered to at all times regarding this product.



Side effects of consuming too much citric acid include stomach cramps, nausea, diarrhoea or vomiting and increased sweating or swelling.
