About Citric Acid Anhydrous Reagent Grade

Citric Acid, also known as 2-hydroxypropane-1,2,3-tricarboxylic acid, has the chemical formula C6H8O7 or CH2COOH-C(OH)COOH-CH2COOH. It appears as colorless, odorless crystals with an acid taste. It is very soluble in Water, Ethanol, and Ether at ambient conditions. When heated to decomposition it emits acrid smoke and fumes. Chemicals in the Reagent Grade category have high purity and are best suited for analytical purposes. They're useful in research investigations as they produce consistent, trustworthy, and repeatable findings.

Questions & Answers

  • Is anhydrous citric acid oil soluble? I see citric acid in oil based cleaning products and wonder if you supply it in a form which will mix with soybean oil and saudium laurel sulfate?

    Citric acid is not soluble in oil. It is soluble in water and alcohols. Sodium lauryl sulfate is an anionic surfactant and using sodium lauryl sulfate can dissolve citric acid to some extent in soyabean oil or other oil.
