🔧 Applications of Citric Acid Anhydrous 99%

1. Food and Beverage Industry

Citric Acid Anhydrous 99% is a vital additive in the food and beverage industry, where it serves as a flavor enhancer, acidulant, and preservative. It is commonly used in carbonated drinks, juices, jams, gelatins, and confectioneries to add a tangy taste and maintain pH stability. Additionally, it acts as a natural preservative by inhibiting microbial growth and enzymatic spoilage, thereby extending shelf life.

2. Pharmaceutical Industry

In the pharmaceutical sector, citric acid anhydrous is used to adjust pH, enhance taste masking, and stabilize active ingredients in formulations. It is frequently found in effervescent tablets, syrups, and antacids. Due to its high purity and solubility, it ensures the effectiveness of medicinal formulations and improves patient compliance.

3. Cosmetics and Personal Care

Citric acid is a common ingredient in skin care, hair care, and oral hygiene products. It is used to adjust pH levels to suit skin compatibility, enhance preservative performance, and assist in the exfoliation of dead skin cells. It also serves as a chelating agent to stabilize formulations and improve shelf life.

4. Cleaning and Detergents

Anhydrous citric acid is widely used in cleaning products such as descalers, dishwasher detergents, and bathroom cleaners. Its ability to chelate metal ions and dissolve mineral scales like calcium and limescale makes it effective in hard water environments. It is a safer alternative to harsher chemicals and is biodegradable, making it ideal for eco-friendly cleaning solutions.

5. Industrial Uses

Industrially, citric acid anhydrous acts as a chelating agent, helping remove heavy metals from water and stabilizing products in metal cleaning, textile dyeing, and electroplating processes. Its buffering properties also make it useful in chemical manufacturing and laboratory applications.
