Applications in Key Industries

Construction Materials

Hydroxypropyl starch ether is widely used in the construction industry as an additive for cement-based and lime-calcium-based putty products and mortars. Its compatibility with other admixtures enhances workability while reducing the need for cellulose ethers. For example, when combined with methyl cellulose ether, it improves thickness, internal structure, and crack resistance. This makes it ideal for:

• Internal and external wall putty powders
• Decorative mortars and plastering mortars
• Ceramic and porcelain product adhesives

Textile Industry

In the textile sector, hydroxypropyl starch ether serves as a warp size, increasing wear resistance and weaving efficiency. Its high substitution degree also makes it an effective thickener for textile treatments. This application reduces material waste and improves production efficiency, aligning with sustainability goals.

Daily Chemical and Cosmetics Industry

The sodium hydroxypropyl starch phosphate variant is used as a binder, suspending agent, and thickener in cosmetics and daily chemical products. Its ability to stabilize aqueous solutions and improve emulsion properties makes it valuable for formulations like lotions, shampoos, and detergents. Additionally, it enhances the texture and longevity of personal care products.

Oil Drilling Industry

In oil drilling, hydroxypropyl starch ether stabilizes boreholes and improves drilling conditions by preventing sloughing and facilitating flocculation of cuttings. This application is critical for maintaining well integrity and optimizing drilling efficiency in challenging geological environments.
