Citric Acid Monohydrate (C₆H₈O₇ · H₂O) is a natural, biodegradable organic acid widely used as a pH adjuster, chelating agent, descaler, and neutralizer across multiple industries. In textiles, it plays an important role in dyeing, finishing, and wastewater treatment.
Citric acid is commonly used to neutralize excess alkali after:
Cotton reactive dyeing
Vat dyeing
Sulphur dyeing
Scouring/bleaching processes
Benefits:
Stabilizes fabric pH
Prevents yellowing or shade changes
Enhances color fastness
Effectively binds metal ions such as:
Calcium
Magnesium
Iron
Functions:
Prevents metal contamination in dye baths
Ensures uniform dyeing
Improves shade accuracy
Used to remove:
Limescale buildup in machines
Iron stains on fabrics
Mineral deposits in pipelines and boilers
After bleaching, citric acid is used to prevent:
Alkaline-induced yellowing
Oxidation yellowing during drying
Used in finishing baths to:
Maintain stable pH
Improve softness and handle
Protect sensitive fibers
Citric acid is used for:
pH adjustment
Chelation of heavy metals
Improving coagulation efficiency
Dosage depends on process type and water hardness.
Neutralization after dyeing: 0.5–2 g/L
Chelation/water softening: 0.1–1 g/L
Descaling/cleaning: 1–5% solution
Wastewater treatment: 10–200 mg/L depending on pH correction needs
Biodegradable and eco-friendly
Safe alternative to strong mineral acids
Excellent chelating power
Multi-functional across dyeing and finishing
Improves process stability and fabric quality
Acidity regulator
Flavor enhancer
Preservative
Fruit drinks, soft drinks, candies, jams
Chelating agent to improve cleaning efficiency
Scale removal in household cleaners
Dishwasher tablets, laundry detergents
pH adjuster in creams, lotions, shampoos
Antioxidant stabilizer
Used in bath bombs and skincare formulas
Buffering agent in syrups and solutions
Effervescent tablets (combined with sodium bicarbonate)
Stabilizer in vitamin C products
Neutralization
Metal removal
Boiler and cooling system descaling
pH adjustment in nutrient solutions
Chelating agent in fertilizers
Soil conditioner for alkaline soils
Non-toxic and safe under normal handling
Avoid inhalation of dust
Store in cool, dry areas
Use gloves and eye protection during industrial use
