Sodium Dehydroacetate

Description

1. Product Overview
   Sodium Dehydroacetate is a crystalline sodium salt of dehydroacetic acid, used as an effective preservative and antimicrobial agent across industrial formulations. Primarily deployed to inhibit mold, yeast, and bacterial growth, it protects water-based products, coatings, adhesives, and dry-mix formulations. Its key value proposition is broad-spectrum preservative efficacy combined with high thermal and pH stability, enabling longer product shelf life and lower failure rates in manufacturing and distribution. Strategically, Sodium Dehydroacetate reduces recall risk, lowers in-line biocontrol costs, and supports regulatory-compliant preservation strategies for large-scale industrial users.

2. Key Specifications & Technical Characteristics

• Chemical name: Sodium Dehydroacetate (IUPAC: sodium 3-acetyl-4-hydroxy-6-methyl-2H-pyran-2-one salt).

• Chemical formula: C8H7NaO3 (typical).

• Purity/grade: Industrial/Bulk grade, typical assay ≥ 98.0% (adjustable to customer specification).

• Physical form: Free-flowing white to off-white crystalline powder.

• Particle size: Standard D90 ≤ 250 µm; customizable milling to finer spec on request.

• Bulk density: Typical 450–650 kg/m³ (tapped).

• Solubility: Soluble in water (forming clear to slightly opalescent solution), higher solubility in basic media; compatible with common solvent systems used in coatings and adhesives.

• pH stability range: Effective and stable across a broad pH range (approx. pH 3–9 operational range; performance optimized with pH above 5).

• Thermal stability: Stable under typical processing temperatures used in water-based formulations; withstands short-term elevated temperatures encountered in industrial mixing and drying.

• Impurities: Meets industrial tolerances for residual solvents, heavy metals, and related organics; certificates of analysis supplied per batch.

• Packaging options: 25 kg multi-ply kraft bags with polyethylene liner; 500 kg–1,000 kg FIBC (bulk bag); 20 MT palletized bulk shipments for container loads.

• Shelf life: Minimum 24 months when stored in original, unopened packaging in a cool, dry environment away from direct sunlight and moisture.

• Regulatory documentation: Material Safety Data Sheet (MSDS/SDS), Certificate of Analysis (CoA), and other regulatory dossiers available upon request.

3. Core Industrial Applications

• Paints & Coatings: Used as a preservative to prevent microbial spoilage in waterborne paints, primers, and emulsions during production, storage, and application, reducing batch failures and extending usable pot-life.

• Construction Materials: Incorporated into gypsum, cement-based waterproofing slurries, and tile adhesives to control mold and bacterial growth in damp environments.

• Adhesives & Sealants: Preserves waterborne adhesive systems and reduces viscosity changes caused by microbial contamination, enabling consistent bonding performance.

• Dry-Mix Formulations: Protects powdered formulations (e.g., mortar mixes, cement additives) from microbial contamination during storage and transport.

• Industrial Cleaning & Detergents: Contributes to product stability in concentrated and diluted cleaning formulations, especially for institutional and industrial uses.

• Leather & Textile Finishing: Used to inhibit microbial degradation during storage and processing of aqueous finishing baths.
  Why it outperforms alternatives:

• Broad-spectrum efficacy against mold, yeast, and bacteria at low use rates, delivering cost-effective protection versus higher-dose alternatives.

• Superior thermal and pH stability reduces degradation during typical processing steps.

• Compatibility with a wide range of formulation chemistries minimizes reformulation risk when switching suppliers.

• Lower risk of odor or color impact compared with some organic preservatives, ensuring product quality and customer acceptance.

4. Competitive Advantages

• Quality consistency: Batch-controlled manufacturing with CoA and traceable quality metrics to ensure reproducible preservative performance across large-volume runs.

• Supply reliability: Dedicated production capacity and strategic inventory management to support continuous supply for industrial-scale purchasers and critical projects.

• Logistics capability: Multiple packaging formats optimized for containerized export and bulk handling; experience shipping to global industrial hubs with timely ETAs and export documentation.

• Price competitiveness: Economies of scale for bulk procurement (20 MT container-level pricing) plus flexible contract terms for repeat buyers to lower total cost of ownership.

• Sustainability: Efficient production processes with minimized waste streams; product usage reduces product loss and waste across customer supply chains, contributing to circularity and lower lifecycle impacts.

• Technical support: Application guidance, CoA, SDS, and formulation support available from technical service teams to accelerate qualification and scale-up; on-request stability and compatibility testing.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT.

• Loading capacity (MT per container): Up to 20 MT per 20-foot container (palletized 25 kg or FIBC formats), subject to packaging configuration and destination transport regulations.
