Product Description

Product Description

Citric Acid Monohydrate

    Citric Acid Monohydrate is a weak organic acid containing one molecule of water of crystallization, with the chemical formula C₆H₈O₇·H₂O. It is a natural component and metabolic intermediate in citrus fruits and is produced industrially through the microbial fermentation of carbohydrate sources (e.g., molasses) using the fungus Aspergillus niger. As one of the most widely used food additives, it is prized for its pleasantly sharp sour taste, excellent solubility, and multifaceted functionality as a natural acidulant, preservative, chelating agent, and pH buffer. It is generally recognized as safe (GRAS) and is biodegradable.

Application

Food & Beverage Industry

Pharmaceutical & Dietary Supplements

    It is predominantly used as a natural acidulant and flavor enhancer in a vast array of products including soft drinks, fruit juices, candies, jams, and dairy products. It regulates acidity (pH), imparts a refreshing tartness, and acts as a preservative by chelating metal ions that catalyze spoilage. In the production of processed cheese, it serves as an emulsifying salt.

    In pharmaceutical formulations, it functions as an active ingredient in effervescent tablets and powders (reacting with carbonates to produce CO₂), an antioxidant stabilizer, a pH adjuster in syrups and solutions, and a chelating agent to enhance the stability and bioavailability of certain active compounds. It is also used as a souring agent in some vitamin C formulations.

Cosmetics & Personal Care

Industrial & Household Cleaning

    Due to its alpha-hydroxy acid (AHA) properties, it is used in skincare products as a gentle exfoliant and pH adjuster. It acts as a chelator in shampoos and soaps to improve lather in hard water and as a preservative booster in various formulations.

    Its powerful chelating ability makes it highly effective in detergents, cleaners, and descaling agents. It binds to and removes metal ions like calcium and magnesium from surfaces (e.g., kettles, boilers) and fabrics, preventing scale formation and improving cleaning efficiency. It is a key component in many eco-friendly cleaning products.
