Citric Acid Monohydrate Acidity Regulator High Content 99.8% CAS NO 5949-29-1

Citric Acid Monohydrate: A Versatile Natural Additive

Citric Acid Monohydrate is a colorless crystal or white particle organic acid with the chemical formula C₆H₈O₇·H₂O. It is a natural ingredient that is widely found in fruits such as lemons and oranges and has a refreshing sour taste.

Chemical Structure

The chemical formula of citric acid monohydrate is C₆H₈O₇·H₂O. It is a hydrate form of citric acid, itself an organic acid with three carboxyl groups (-COOH) in its molecular structure. This structure gives it unique chemical properties, allowing it to act as an acid in many chemical reactions, such as neutralization reactions with bases.

Physical Properties
In appearance, citric acid monohydrate appears as colorless crystals or white crystalline powder. It has a pleasant sour taste, which is one of the reasons why it is widely used in the food industry. In terms of solubility, it is easily soluble in water and its aqueous solution is acidic. The melting point is relatively low, about 100°C. When the temperature rises above the melting point, it will melt. As the temperature rises further, reactions such as decomposition may occur.

Applications

• Food Industry:Citric acid monohydrate is an important souring agent in food and beverages. It is widely used in the production of various juices, drinks, candies, jams, etc. For example, in lemon juice drinks, it can provide a sour taste similar to natural lemons and enhance the taste of the drink. In candy making, it can adjust the acidity of the candy, giving the candy a sweet and sour taste. It can also play a certain preservative role and extend the shelf life of the candy.
• Pharmaceutical Industry:Citric acid monohydrate also has important applications in the pharmaceutical field. It can be used as an acidifier in pharmaceutical preparations to adjust the pH value of the drug to ensure the stability and effectiveness of the drug. For example, some drugs maintain the stability of their active ingredients within a specific pH range, and citric acid monohydrate can be used to create such an environment. In addition, it can also be used in the synthesis process of certain drugs as a reactant to participate in chemical reactions.
• Daily Chemical Industry:In daily chemical products, citric acid monohydrate is often used to make detergents, shampoos, skin care products, etc. In detergents, it can be used as a chelating agent to combine with metal ions in the water to prevent the influence of metal ions on the detergent effect. It can also play a certain role in decontamination and whitening. In shampoos and skin care products, it can adjust the pH value of the product to make it suitable for the physiological environment of the skin and hair, such as making the pH value of the shampoo close to the pH value of the scalp to reduce irritation to the scalp.
