Citric Acid Monohydrate

Whatsapp Order

Citric Acid Monohydrate is a white, crystalline powder or granule form of citric acid containing one molecule of water per molecule of acid. It is a natural organic acid commonly derived from citrus fruits or produced by fermentation processes. Citric Acid Monohydrate is widely used as an acidulant, preservative, and chelating agent in various industries. Compared to the anhydrous form, it has a slightly lower acid concentration due to the water molecule but offers excellent solubility and stability. It is prized for its sour flavor, buffering capacity, and ability to bind metal ions, making it indispensable in food, pharmaceutical, cosmetic, and industrial applications.

Citric Acid Monohydrate Uses

Table of Contents

Primary Uses

Food & Beverage Industry

Used as an acidulant and flavor enhancer in soft drinks, candies, fruit juices, and dairy products.
Functions as a preservative by chelating metals and preventing oxidation, thus extending shelf life.
Acts as a pH regulator and buffering agent in food processing.
Incorporated in effervescent tablets and powders to provide controlled release of carbon dioxide when reacted with bicarbonates.

Pharmaceuticals & Nutraceuticals

Employed as a pH adjuster in oral syrups, suspensions, and effervescent dosage forms.
Serves as a stabilizer for active pharmaceutical ingredients sensitive to alkaline conditions.
Used to enhance mineral absorption by chelating metal ions in vitamin and mineral supplements.

Cosmetics & Personal Care

Added as a pH adjuster in skincare products, shampoos, and bath additives.
Acts as an antioxidant synergist by binding metal ions that can catalyze product degradation.
Utilized in mild exfoliating products due to its gentle acidity and natural origin.

Industrial & Cleaning Applications

Used as a biodegradable chelating agent and scale remover in detergents and cleaning agents.
Applied in metal surface treatment and as a descaling agent for boilers and cooling systems.
Functions as a buffering agent in chemical manufacturing processes and laboratory reagents.

Secondary Uses

Agriculture

Used in micronutrient fertilizers and foliar sprays to improve metal ion availability to plants.

Water Treatment

Employed as a sequestrant to control hardness and prevent precipitation of calcium and magnesium salts.

Textile Industry

Utilized in dyeing and finishing to adjust pH and enhance color consistency and brightness.

Food Packaging

Incorporated in active packaging materials for its antimicrobial and antioxidant properties.
