Description

Citric Acid CAS NO 77-92-9 is a weak organic acid, a key intermediate in the citric acid cycle, and one of the most versatile and widely used organic acids in the world. Its primary value lies in its excellent chelating, buffering, and acidifying properties, making it a safe and effective multi-purpose ingredient. This compound is essential for manufacturers in the food & beverage, pharmaceutical, personal care, and industrial cleaning sectors, where it acts as a flavor enhancer, preservative, pH adjuster, and descaling agent.

Application

• Food & Beverage Industry: As an acidulant, flavor enhancer, and preservative (E330) in soft drinks, candies, jams, and processed foods.
• Pharmaceuticals & Nutraceuticals: As an excipient in effervescent tablets and powders, a pH buffer in formulations, and a chelating agent in active pharmaceutical ingredients (APIs).
• Detergents & Cleaning Products: As an environmentally friendly descaling and chelating agent in liquid detergents, dishwasher products, and industrial cleaners to remove limescale.
• Cosmetics & Personal Care: As a pH adjuster and antioxidant in skin creams, shampoos, and other formulations to enhance stability and efficacy.
• Industrial Applications: As a chelating agent in electroplating baths, a retarder in concrete, and a component in chemical synthesis.
• Water Treatment: Used to chelate metal ions, preventing scale formation and corrosion in boiler and cooling water systems.

Quality Control

We supply Citric Acid in various grades, including Food Grade (FCC), Pharmaceutical Grade (USP/EP), and Technical Grade, to meet diverse industrial requirements. Our products undergo rigorous quality testing to ensure compliance with the relevant pharmacopoeial or industry standards. A Certificate of Analysis (COA) is provided with each batch to guarantee specifications for purity, heavy metals, and other critical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after use to prevent caking due to moisture absorption. Keep away from incompatible materials such as strong bases, oxidizing agents, and nitrates.
