Product Features & Advantages

Core Benefits of Citric Acid Monohydrate Bulk

Enhanced Stability: Water molecule in crystal structure improves stability in humid conditions
Controlled Solubility: Predictable dissolution rates ideal for pharmaceutical formulations
Superior Buffering: Effective pH control (3-5) in citrate buffer systems
Antioxidant & Chelating Properties: Protects active ingredients from oxidation and metal ion degradation

vs Anhydrous Citric Acid

Unlike water-free anhydrous citric acid, Food Grade Citric Acid Monohydrate Powder and Pharmaceutical Grade Citric Acid Monohydrate Crystalline Powder offer better compatibility with moisture-sensitive pharmaceutical formulations, enhanced stability in intermediate-moisture foods, and improved texture in cosmetics—making it ideal for complex formulations requiring precise moisture control.

Usage Guidelines for Citric Acid Monohydrate Bulk

Define Application: Identify use as acidulant, preservative, pH adjuster, or antioxidant
Calculate Dosage: 0.1-2.0% for food applications; 0.5-5.0% for pharmaceuticals
Prepare Solution: Dissolve in water at recommended temperatures for optimal solubility
Integrate into Formulations: Add at appropriate manufacturing stages
Verify Quality: Test pH, solubility, and ingredient compatibility
Store Properly: Keep in airtight containers at room temperature, away from moisture

Frequently Asked Questions (FAQ)

Q1: What is the difference between citric acid monohydrate and anhydrous citric acid?

A: Monohydrate contains one water molecule (C6H8O7·H2O) for better humid stability and controlled solubility, while anhydrous is water-free (C6H8O7). Monohydrate is preferred for pharmaceuticals and moisture-sensitive foods.

Q2: Is it safe for pharmaceutical use?

A: Yes, Pharmaceutical Grade Citric Acid Monohydrate Crystalline Powder meets USP/BP/EP standards and is safe for drug formulations when used per guidelines.

Q3: How does temperature affect solubility?

A: Solubility rises with temperature: 54.0% (w/w) at 10°C, 59.2% (w/w) at 20°C, 84.0% (w/w) at 100°C—critical for formulation development.

Q4: Can it be used in organic products?

A: Acceptability depends on organic certification standards; we provide documentation to support organic certification applications.

Q5: What is the shelf life and storage recommendation?

A: 36 months when stored in airtight containers at room temperature, away from moisture (prevents caking and maintains quality).

Q6: How does it compare to other acidulants?

A: It offers a clean tart taste, multifunctional benefits (preservative + flavor enhancer), and a natural profile, making it preferred over other acidulants in food applications.
