CITRIC ACID

Applications

• Water treatment & Sanitation: 
  • ?RO Membrane Cleaning: It is a primary chemical used in Clean-In-Place (CIP) procedures for Reverse Osmosis (RO) systems to safely dissolve and strip away inorganic fouling, mineral scale (like calcium carbonate), and metal oxides without degrading the membrane.
  • Ion Exchange Regeneration: It helps clean iron deposits out of water softener resin beds.
  • Passivation: It is used to clean and passivate stainless steel piping systems, removing free iron from the surface to prevent rust.
• Food & Beverage Industry: 
  • Acidulant & Flavoring: Provides the characteristic "sour" kick in carbonated soft drinks, candies, jams, and juices.
  • Preservative: Lowers pH levels to inhibit microbial growth, extending shelf life.
  • Antioxidant Booster: Prevents the enzymatic browning of cut fruits by binding trace metals that accelerate oxidation.
• Industrial, Detergents & Cleaning Agents: 
  • ?Scale Removal: Formulated into household and industrial descalers to strip limescale out of boilers, heat exchangers, and coffee makers.
  • Eco-Friendly Builder: Replaces polyphosphates in laundry and dishwashing detergents to soften water and improve surfactant performance.

• Pharmaceuticals & Cosmetics: 

  • Effervescent Tablets: Paired with bicarbonates in antacids, vitamins, and bath bombs, when introduced to water, they react to release carbon dioxide gas, causing the fizzing effect.

  • pH Adjustment: Used to stabilize the pH level in skin lotions, shampoos, and topical creams.
