In the Water treatment and industrial wastewater treatment field, the shift toward “green chemistry” is no longer just a trend but a regulatory requirement. Although synthetic polymers have long been the dominant choice in the market, Pregelatinized E1404 (Oxidized Starch) is now emerging as a strong bio-based alternative for flocculation and coagulation processes. For international distributors and environmental consultants, sourcing a high-quality modified starch that ensures both good performance and cost efficiency remains the main objective.
What is Pregelatinized Oxidised Starch?
Pregelatinized oxidized starch (also known as pregelatinized oxidised starch or Pregelatinized E1404) is a type of starch that is modified through two processes: chemical oxidation and physical pregelatinization.
Oxidation (chemical modification): Native starch is treated with an oxidizing agent such as sodium hypochlorite. This process partially breaks down glucose units and introduces carbonyl and carboxyl groups. As a result, the starch has lower viscosity, improved stability, better film-forming ability, and reduced retrogradation, meaning it is less likely to gel or harden over time.
Pregelatinization (physical modification): After oxidation, the starch is cooked using heat and moisture to gelatinize it, then dried—typically by drum drying or spray drying—and ground into a fine powder. This process breaks down the natural granular structure of the starch, allowing it to dissolve in cold water without requiring heat.

Why Pregel E1404 for Water Treatment?
Pregelatinized Oxidized Starch (E1404) provides several unique advantages that synthetic chemicals cannot easily achieve:
- Instant solubility in cold water: Unlike conventional starches, this pregelatinized form dissolves immediately in cold water, making it easy and fast to prepare flocculant solutions directly at the application site.
- Improved flocculation performance: The oxidation process introduces carboxyl groups, which significantly enhance the starch’s ability to capture and bind suspended particles, heavy metals, and organic impurities.
- Biodegradable and eco-friendly: This starch is fully biodegradable and helps lower the chemical oxygen demand (COD) in wastewater compared to petroleum-based polymers, making it a more environmentally friendly choice.
The Vietnam Advantage: Technology Meets Trade
Sourcing Pregel E1404 from a specialized manufacturer in Vietnam gives you a strategic advantage that goes beyond laboratory performance.
-
R&D Exclusivity & Customization
Unlike most suppliers that only provide standard products, our facility is the first in Vietnam with the R&D capability to adjust Pregel E1404 specifications. Depending on your needs—such as stronger viscosity for sludge dewatering or specific solubility behavior for municipal water treatment—we can tailor the product structure to match your equipment and application requirements.
