• Global Safety Compliance: No carcinogenic ingredients (IARC/OSHA certified), meeting FDA, EU Food Grade, and ISO standards for safe use in food and nutrition products.
• Versatile Compatibility: Works seamlessly with Nutritional Supplements, food formulations, and industrial materials without chemical reactions.
• Consistent Quality Control: Produced under GMP standards with strict batch testing, ensuring uniform performance across all orders.

How to Use

1. Determine Application Requirement: Confirm usage scenario (e.g., food preservation, solvent drying, or industrial processing) and required dosage.
2. Precise Measurement: Use analytical tools to weigh the required amount (typically 0.1-2% for food applications, 5-10% for drying processes).
3. Uniform Mixing: Blend Anhydrous Sodium Sulphate evenly with target materials (e.g., food products, solvents, or Plant Extract solutions) under room temperature.
4. Process Implementation: For food preservation: Add during the final processing stage; For drying: Stir vigorously with wet materials and let stand for 30-60 minutes.
5. Post-Use Handling: Remove excess anhydrous sodium sulphate via filtration (for liquid applications) or natural separation (for solid mixtures) if needed.
