Citric acid is an organic compound found in fruits such as lemons, oranges, and berries. Its versatility makes it widely used in industries like food and beverages, cosmetics and pharmaceuticals, detergents, and cleaning products.
Benefits and uses of citric acid
Citric acid has various applications in daily life due to its multifunctional properties, such as:
Food and drinks
- Preservation: Helps extend the shelf life of food and drinks by inhibiting microbial growth.
- Flavoring: Adds a sour taste to soft drinks, juices, candies, and desserts like jelly and pudding.
- Acidity regulation: balances the acidity in products such as sauces, dressings, and canned foods.
Cosmetics and body care products
- pH balance: Maintains the pH level in skincare products like lotions, creams, shampoos, and conditioners.
- Exfoliation: Mildly exfoliated in skincare products to help remove dead skin cells.
Cleaning products
- Stain removal: Aids in removing stains and dirt, enhancing detergent effectiveness.
- Descaling: Eliminates limescale and stains from surfaces in kitchens and bathrooms.
Pharmaceuticals
- Stability: Maintains the stability and extends the shelf life of medications.

Risks of using citric acid
While citric acid is generally considered safe, there are some risks to be aware of, particularly when used in large quantities, such as:
Skin irritation
Prolonged contact can cause skin irritation, including burning, swelling, or itching. If this occurs, wash the affected area immediately and avoid repeated exposure.
Eye irritation
Accidental contact can cause a burning sensation in the eyes. Flush the eyes with clean water for several minutes and remove contact lenses if worn.
Dental issues
Consuming foods and drinks with citric acid can erode tooth enamel, leading to increased sensitivity, yellowing, and a higher risk of cavities. To prevent this, use a straw when drinking acidic beverages and brush your teeth with fluoride toothpaste.
Stomach discomfort
Some people may experience nausea or vomiting when using medications or supplements with citric acid due to natural sensitivity.
Allergic reactions
Rarely, individuals may be allergic to citric acid, with symptoms such as rashes, skin irritation, itching, and in very rare cases, difficulty breathing.
Understanding the benefits and risks of citric acid can help you use it wisely and avoid overexposure, thereby preventing negative health effects.
