Citric acid monohydrate丨CAS 5949-29-1 is the monohydrated form of citric acid, a naturally occurring organic acid widely used across food, pharmaceutical, cosmetic, and industrial sectors. With the molecular formula C₆H₈O₇·H₂O, it appears as a colorless or white crystalline powder and is highly soluble in water. It is recognized for its acidifying, chelating, and preserving properties.
Applications of Citric acid monohydrate丨CAS 5949-29-1
1. Food and Beverage Industry
Citric acid monohydrate丨CAS 5949-29-1 is a key ingredient used as a:
● Flavoring agent: Provides a tangy or sour taste to soft drinks, candies, and jams.
● Acidulant: Adjusts pH and enhances the stability of food products.
● Preservative: Inhibits microbial growth and extends shelf life, especially in canned and processed foods.
● Emulsifying salt: Helps maintain the consistency of dairy products and sauces.
2. Pharmaceutical Industry
In pharmaceutical formulations, citric acid monohydrate is used to:
● Stabilize active ingredients in effervescent tablets, syrups, and powders.
● Adjust pH in injectable and oral drug products.
● Enhance solubility and bioavailability of certain drugs.
● Serve as a chelating agent to bind metal ions and improve formulation stability.
3. Cosmetics and Personal Care
Citric acid monohydrate is incorporated into:
● Shampoos and conditioners to balance pH and smoothen hair cuticles.
● Skin-care products as a mild exfoliant and pH adjuster.
● Bath bombs and fizzy products due to its effervescence when combined with bicarbonates.
4. Cleaning and Industrial Applications
In industrial cleaning, citric acid monohydrate acts as a:
● Descaling agent: Removes limescale from boilers, kettles, and pipes.
● Chelator: Binds and removes metal ions in detergents and metal-cleaning formulations.
● Eco-friendly alternative to harsher acids like hydrochloric or sulfuric acid.
5. Agriculture and Biotechnology
● Used as a pH regulator in nutrient solutions for hydroponics and fertilizers.
● In fermentation and biotechnology, it aids in maintaining optimal culture conditions.
Benefits of Citric acid monohydrate丨CAS 5949-29-1
1. Biodegradable and Environmentally Safe
Citric acid monohydrate丨CAS 5949-29-1 is non-toxic, fully biodegradable, and safe for both consumers and the environment, making it a preferred choice in sustainable product formulations.
2. Versatile and Multifunctional
Its acidic, buffering, and chelating properties make it useful across a wide range of applications-from food to pharmaceuticals to cleaning products.
3. Safe for Consumption
Classified as Generally Recognized As Safe (GRAS) by the U.S. FDA, citric acid monohydrate is widely accepted for ingestion and topical use with minimal side effects.
4. Stable and Easy to Handle
The monohydrate form offers better stability and handling properties compared to the anhydrous form, especially in humid environments, making it suitable for consistent processing.
