Product Overview

Citric Acid 25% Solution is a clear, colorless liquid acidulant formulated for demanding industrial applications. Composed of 25% w/w Citric Acid (C₆H₈O₇) in an aqueous base, this solution provides precise pH control and robust chelating properties. Sometimes referred to as liquid Sour Salt or E330, this product effectively sequesters trace metals and removes mineral scale.

Unlike powdered forms, this pre-dissolved 25% solution eliminates the need for mixing and agitation, ensuring immediate integration into process streams. It is chemically stable and compatible with standard HDPE and glass processing equipment. This product is ideal for water treatment, metal finishing, surface preparation, and general chemical manufacturing where consistent acidity and metal ion sequestration are required.

Key Properties

  • Chemical Name: Citric Acid
  • Chemical Formula: C₆H₈O₇
  • Concentration: 25% w/w (Typical)
  • Appearance: Clear, colorless liquid
  • Specific Gravity: 1.05–1.07 (Typical 1.06)
  • Solubility: Fully miscible in water
  • CAS Number: 77-92-9
  • Heavy Metals (as Pb): Max 1 ppm
  • Iron (Fe): Max 1 ppm

Common Applications

  • pH Control: Used to lower pH in industrial wastewater treatment and process streams without introducing mineral acids.
  • Metal Finishing: Acts as a passivation agent for stainless steel, removing free iron from the surface to prevent corrosion (meets ASTM A967 standards for citric acid passivation).
  • Industrial Cleaning: Highly effective for chelating calcium and magnesium ions, making it an excellent descaling agent for boilers, evaporators, and heat exchangers.
  • Water Treatment: Used to sequester trace metals and prevent precipitation in water systems.
  • Chemical Processing: Serves as a buffer and stabilizer in the formulation of detergents, cleaners, and technical coatings.

Safety Precautions

Handling and storage should be performed in a well-ventilated area. While Citric Acid is a weak organic acid, it can cause eye and skin irritation. Wear appropriate Personal Protective Equipment (PPE), including safety goggles, chemical-resistant gloves, and protective clothing when handling bulk quantities. Store in a cool, dry place in tightly closed, corrosion-resistant containers (HDPE or glass). Avoid contact with strong oxidizing agents and strong bases.

Refer to the Safety Data Sheet (SDS) for detailed exposure controls and emergency procedures. In case of eye contact, rinse immediately with water for 15 minutes and seek medical attention. If skin contact occurs, wash thoroughly with soap and water. Product shipments are regulated and labeled according to current safety standards.

Benefits

Ready-to-Use Liquid: Eliminates the labor and safety risks associated with handling and dissolving dry powders.
Powerful Chelation: effectively binds metal ions for superior scale removal and metal passivation results.
Consistent Quality: Manufactured to strict specifications with low trace metal content for reliable process performance.
