What Is Citric Acid Monohydrate?

Citric acid monohydrate (C₆H₈O₇·H₂O) is a weak organic acid naturally found in citrus fruits. It is widely used as a preservative, acidulant, and flavor enhancer in the food and beverage industry. The monohydrate form contains one water molecule, making it slightly different from anhydrous citric acid, which is water-free.

Key Applications of Citric Acid Monohydrate

Food & Beverage Industry – Acts as a natural preservative, pH regulator, and flavor booster in soft drinks, candies, jams, and dairy products.

Pharmaceuticals – Used as an excipient in effervescent tablets and syrups for their chelating and antioxidant properties.

Cleaning Products – An eco-friendly ingredient in detergents and descaling agents due to its ability to dissolve mineral deposits.

Cosmetics & Personal Care – Functions as a pH adjuster in skincare products, shampoos, and bath salts.

Choose the Right Citric Acid Monohydrate Supplier

Selecting a reliable citric acid monohydrate supplier is crucial for ensuring product quality, supply stability, and cost efficiency. Here are the key factors to evaluate:

1. Product Quality & Certifications

Verify if the product meets food-grade standards (FCC/USP/BP/EP) and holds relevant certifications (ISO, HACCP, Halal, Kosher, etc.).

Request a Certificate of Analysis (COA) to check purity (≥99.5%), heavy metal content, and microbial limits.

2.Production Capacity & Supply Reliability

Prefer manufacturers (not just traders) with in-house production to ensure direct quality control and avoid middleman markups.

Assess the supplier’s annual production capacity, inventory levels, and ability to handle urgent orders.

3.Pricing & Cost Structure

Compare bulk pricing among suppliers, including hidden costs (logistics, tariffs, etc.).

Negotiate volume-based discounts for long-term contracts, but avoid compromising quality for lower prices.

4.Logistics & Delivery Efficiency

Check the supplier’s global logistics network—can they handle sea/air freight, bonded warehousing, and on-time deliveries?

Ensure packaging standards (moisture-proof 25kg bags, drums, or custom options) to prevent transit damage.

5.Technical Support & Compliance

A reputable supplier should provide technical documents (MSDS, specifications) and application support for formulation adjustments.

Confirm compliance with regional regulations (FDA, EU, GB) to avoid customs issues.
