Pure Anhydrous Citric Acid

Anhydrous citric acid refers to citric acid that has had all of its water content removed, making it a dry, powdery substance. It’s essentially citric acid in its purest form, with no water molecules attached to it, unlike the more common hydrated form of citric acid, which contains water in its crystalline structure.

Properties of Anhydrous Citric Acid:

• Chemical Formula: C₆H₈O₇ (same as hydrated citric acid, but without water molecules)
• Appearance: White, crystalline powder
• Solubility: Highly soluble in water
• Acidity: Strongly acidic, similar to regular citric acid
• pH: A 1% solution of anhydrous citric acid in water typically has a pH of about 2, which is highly acidic.

Uses:

1. Food and Beverage Industry:
   It's commonly used as a food additive (E330) for flavoring (adding sourness), as a preservative, and for pH adjustment in products like soft drinks, candy, and jams.

2. Cleaning Agent:
   Due to its acidic nature, anhydrous citric acid is used in cleaning and descaling products, particularly in removing mineral deposits or limescale from appliances like kettles, dishwashers, and coffee makers.

3. Cosmetics and Pharmaceuticals:
   Anhydrous citric acid is used in the formulation of certain cosmetic products, such as skin care products (as a pH adjuster), and in pharmaceutical formulations, particularly effervescent tablets.

4. Industrial and Laboratory Applications:
   It can be used in various industrial processes, including as a buffering agent in the manufacture of certain chemicals, or for regulating the acidity in chemical reactions.

Storage:

Since it's anhydrous (i.e., without water), it can absorb moisture from the air, so it should be stored in a tightly sealed container to avoid clumping or deterioration. It should be kept in a cool, dry place.
