Hydroxypropyl Starch (CAS 9049-76-7), often identified by its food additive code E1440, is a cornerstone ingredient for many industries due to its versatile functional properties. From enhancing the texture of foods to improving the performance of industrial products, this modified starch plays a crucial role. For B2B buyers, understanding its characteristics and how to source it effectively is key. As a leading manufacturer and supplier, we provide a comprehensive overview to guide your procurement decisions.

Understanding the Properties of Hydroxypropyl Starch

Hydroxypropyl Starch is produced by chemically modifying native starch with propylene oxide. This process introduces hydroxypropyl ether groups, which significantly alter its native properties:

  • Appearance: Typically a white to off-white powder or granules.
  • Solubility: Unlike native starch, it exhibits improved solubility and dispersibility in cold water.
  • Stability: It is more resistant to thermal degradation and acid hydrolysis, making it suitable for a wider range of processing conditions.
  • Functional Roles: It excels as a thickener, stabilizer, binder, and emulsifier in various formulations.

These enhanced properties make Hydroxypropyl Starch a superior choice over native starches in many applications, driving demand from industries seeking improved product performance and processing efficiency. When you are looking to buy Hydroxypropyl Starch, understanding these core attributes is the first step.

Diverse Applications Across Industries

The versatility of Hydroxypropyl Starch leads to its extensive use in several key sectors:

  • Food Industry: As a food additive (E1440), it is used to improve texture, viscosity, and stability in products such as dairy, bakery goods, sauces, soups, and confectionery. Its ability to provide a smooth mouthfeel and prevent syneresis is highly valued.
  • Pharmaceutical Industry: It serves as an important excipient in tablet formulations, acting as a binder, disintegrant, and filler. Its consistent particle size and flowability are beneficial for tablet manufacturing.
  • Industrial Applications: In the paper industry, it is used for surface sizing and coating. It also finds use in adhesives, textiles, and as a fluid loss control agent in drilling fluids.

For businesses requiring bulk quantities, identifying a reliable hydroxypropyl starch manufacturer is crucial. Sourcing from a direct manufacturer often ensures better price points and a more secure supply chain. When evaluating potential suppliers, consider their production capacity, quality control systems, and commitment to regulatory compliance.

Key Considerations for Purchasing Hydroxypropyl Starch

When procuring Hydroxypropyl Starch, procurement managers should focus on:

  • Supplier Reputation and Reliability: Choose manufacturers with a proven track record of quality and timely delivery. A supplier who can offer consistent supply of modified starch E1440 is essential for continuous production.
  • Product Specifications: Ensure the product's specifications (e.g., viscosity, degree of substitution, purity) meet your exact application requirements.
  • Pricing and Value: Obtain quotes from multiple suppliers to compare pricing, but always factor in quality and service. Understanding the hydroxypropyl starch price in the market will help in negotiation.
  • Technical Support: A supplier that offers technical assistance can be invaluable for optimizing the use of the ingredient in your formulations.
