Citric acid (E330) is a chemically soluble, colorless, crystalline, environmentally friendly substance that is chemically soluble in water. When dissolved in water, citric acid creates a moderately acidic environment, which inhibits the development of many microbes and has a cleansing and descaling effect.
Applications: In the household, citric acid is an effective descaler, used in medicine as well as in environmentally friendly detergents, adds washing activity and decomposes. Used as a water softener, a 6% solution effectively removes soap and limescale from the bathroom, rinsing the surfaces later. Not suitable for acid-sensitive surfaces. Citric acid is a well-known food supplement and preservative.
