Hydroxypropyl Starch Ether (HPS)
Hydroxypropyl Starch Ether (HPS) is a modified starch derived from natural sources through a process of etherification. This process introduces hydroxypropyl groups into the starch molecule, significantly enhancing its properties and making it suitable for a wide range of industrial applications. HPS is widely recognized for its excellent thickening, stabilizing, and water-retaining capabilities, particularly in construction and other demanding fields.

Main features of Hydroxypropyl Starch Ether (HPS) :
Enhanced Water Retention:
HPSE significantly improves the water retention of mortar and other water-based formulations, preventing premature drying. This is crucial for ensuring proper curing and strength development in construction materials.
Film Forming Abilities:
HPSE’s excellent film-forming properties make it ideal for creating coatings and films that protect against moisture, oxygen, and unwanted microbial growth. This is particularly valuable in food packaging and preservation.
Customizable Properties:
The properties of HPSE, such as viscosity and degree of substitution, can be tailored to meet specific needs. This customization enables manufacturers to optimize the performance of their products for specific applications.
Improved constructability：
In construction materials such as mortar and plaster products, HPSE improves the workability of the product, making the mixture easier to apply and spread. This results in a smoother surface and a more efficient application process.
Thickener:
As an effective thickener, HPS imparts viscosity to formulations, helping to improve stability and texture. This makes it valuable in industries such as cosmetics, pharmaceuticals, and food.
Application of Hydroxypropyl starch ether (HPS):
Construction Materials：
Scenarios: Tile adhesives, mortars, gypsum products, and wall putties.
Advantages: HPSE improves workability, enhances water retention, and controls the rheology of construction materials. This leads to easier application, better adhesion, and optimal strength development, ensuring high-quality finishes and durable structures.
Paints and Coatings：
Scenarios: Water-based paints, varnishes, and decorative coatings
Advantages: It acts as a thickener and stabilizer, improving the consistency and spreadability of paints. HPSE helps in reducing splatter during application, provides a smooth finish, and enhances the durability of coatings against environmental factors.
Pharmaceuticals：
Scenarios: Tablet binding, film coatings for pills, controlled release formulations.
Advantages: In pharmaceuticals, HPSE serves as a binder, enhancing the integrity of tablets, and as a film former, it provides controlled drug release. Its use ensures uniformity, improves swallowability, and can modulate drug release profiles for better therapeutic effects.
Food Industry:
Scenarios: Bakery products, sauces, dressings, and dairy alternatives
Advantages: As a thickener and stabilizer, HPSE improves the texture and stability of food products. It can enhance mouthfeel, control syneresis (water retention), and stabilize emulsions, contributing to the overall quality and appeal of food items.
Personal Care and Cosmetics：
Scenarios: Creams, lotions, shampoos, and hair gels.
Advantages: HPSE enhances the texture, consistency, and sensory attributes of personal care products. It provides a smooth, creamy texture, improves moisture retention, and can stabilize emulsions, leading to superior skin and hair care products.
Adhesives and Sealants：
Scenarios: Water-based adhesive formulations.
Advantages: It improves the rheological properties and water retention of adhesives, leading to better adhesion, easier application, and optimal drying times. HPSE can enhance the performance and durability of adhesives for a wide range of applications.
Cleaning Products：
Scenarios:Hand sanitiser, disinfectant, detergent.
Advantages: In cleaning products, HPSE acts as a thickener and stabilizer, improving the viscosity and stability of liquids. This results in more effective cleaning products that are easier to use and provide better results.
