Citric Acid Anhydrous (CAS No. 77-92-9) is a weak organic acid and is used to add a sour taste to drinks and foods. Citric acid's conjugate base is citrate and an important intermediate in the citric acid cycle in biochemistry.
Citric acid is the world's largest organic acid produced by biochemical methods. Citric acid and its salts are one of the pillars of the fermentation industry and are mainly used in the food industry as acidifier, solubilizer, buffering agent, antioxidant, deodorizer, flavor enhancer, gelling agent, coloring agent, etc.

1. Food Additive
Citric acid is used in food as a flavouring agent and preservative.
It is used in processed food products like beverages, soft drinks etc.
Due to its sour taste, it is used in making certain candies.
Sometimes the sour candy is covered with white powder which is citric acid.
To keep fat globules away some ice cream companies use it as an emulsifier.
2. Cleaning Agent
Citric acid is one of the chelating agents.
With the help of citric acid limescale from evaporators and boilers is removed.
It is used in soaps and laundry detergents as water are softened by the acid.
Household cleaners used in kitchen and bathroom also contain some amount of citric acid.
It is not only used as a cleaner but also as a deodorizer.
3. Cosmetics
Citric acid helps in the removal of dead skin so used for home masks.
Improves skin tone and skin growth reducing wrinkles, acne scars etc.
To balance the pH levels citric acid is commonly used the ingredient in cosmetics.
It is found in hand soap, body wash, nail polish face cleansers, shampoos and some other cosmetics products.
4. Water Softener
Citric acid is used as a water softener in detergents, because of it's an organic acid, chelating, and buffering properties.
The chemical properties of citric acid as a weak organic acid make it a strong softener for water.
It operates by breaking down the trace quantities of metal discovered in water, making it an optimal all-natural option for hard water treatment.
5. Industrial Uses
Industrial uses of citric acid include detergent manufacturing, electroplating and leather tanning.
Citric acid is also used as a preservative for stored blood and a buffer and antioxidant in the pharmaceutical and cosmetic industries.
Several fungal-derived acids have significant commercial value and have found wide-ranging applications in the food, feed, pharmaceutical and polymer industries.
