Application Overview

Our Anhydrous Citric Acid is engineered to deliver outstanding performance across several sectors:

• Food & Beverage:
  Used extensively as an acidulant and pH regulator in beverages, confectioneries, and canned goods. Anhydrous citric acid adds a signature tartness and also acts as a preservative to extend shelf life without artificial additives. It is ideal for dry mix beverages, effervescent drinks, and instant food preparations due to its stability and reactivity upon dissolution.

• Pharmaceuticals:
  Essential for the production of effervescent tablets, oral care products, and buffering agents in injectable drugs. In medicinal applications, it enhances bioavailability and maintains pH stability, crucial in formulations such as antacids, cough syrups, and electrolyte mixtures.

• Personal Care & Cosmetics:
  An ideal choice for pH adjustment in skincare, haircare, and bath products. Its mild exfoliating effect is valued in serums, masks, and cleansers, where it helps to balance skin tone and gently remove dead cells. Citric Acid Anhydrous is also effective in preventing oxidation, increasing the shelf life and efficacy of sensitive formulas.

• Household & Industrial Cleaning:
  Widely used as a biodegradable chelating agent in hard water environments, anhydrous citric acid efficiently binds metal ions, which aids in preventing soap scum and scaling in detergents, dishwashing liquids, and household cleaners. It also plays a role in eco-friendly descaling agents and is ideal for formulating water-softening products.

• Water Treatment and Metal Finishing:
  In industrial and municipal water treatment, anhydrous citric acid adjusts pH and prevents mineral deposits in water systems. It is also effective in metal cleaning processes, where it removes oxides and improves surface quality before coatings and finishes are applied.

Usage Guidelines & Safety

Usage Recommendations:

• Food & Pharma: Dissolve at required concentration for pH adjustment and preservative effect.

• Cosmetic Applications: Use as per formulation requirements for pH control and stabilization.

• Industrial Cleaning: For hard water applications, use in diluted form for safe descaling.

Handling & Precautions:

• Handle with gloves and protective eyewear; avoid inhaling dust.

• Store in a cool, dry environment, away from alkaline substances and oxidizers.
