Applications
Citric acid 0AQ is applied in various ways, for instance:
1. Food Industry
Citric acid is an essential additive in the Food Industry. It is used as an acidity regulator (as food additive E330), preservative and flavor enhancer in beverages, sweets, preserves, dairy products and more. It extends the shelf life and improves the taste of products.
2. Pharmaceutical Industry
In medicines, citric acid is used as an adjuvant for stabilizing active ingredients and adjusting pH. It is also used in effervescent technology (such as effervescent tablets) and syrups.
3. Textile & Metal Industry
It is used at equipment cleaning and as an environmentally friendly alternative to phosphates in detergents. In the electroplating industry, it is used for metal cleaning and descaling.
4. Industrial & Technical Applications
Citric acid acts as a chelating agent, for example, in Water Treatment or at removing scale in industrial processes. In cleaning agents, it is used because of its ability to bind metal ions and clean surfaces.
5. Cosmetic Industry
Citric acid is widely used in skin care products, shampoos and conditioners because of its exfoliating properties and its ability to regulate a product’s pH.
