CAS: 9063-38-1
Modified starches are compounds derived from natural starches, chemically transformed to enhance their functionality for specific industrial applications. Unlike traditional starches, these are altered through processes such as oxidation, hydrolysis, or phosphorylation, which grant them unique, controllable properties like improved resistance to extreme temperatures and customizable consistency. The significance of modified starches has grown since the mid-20th century, as industries sought sustainable solutions, particularly for sectors like construction and food production.
Interestingly, modified starches can retain their texture and stability even under high heat and humidity conditions.
Chemical Properties of Modified Starches
● CAS number： 9063-38-1
● Molecular formula： C2H4O3·xNa·x
Physical Properties
● Appearance: white to beige fine or granular powder
● Odor: odorless

Application in the Construction Industry
Modified starches are commonly used as adhesive agents and thickeners in construction materials. Due to their ability to enhance viscosity and stabilize mixtures, they are widely employed in the formulation of cements and plasters. Furthermore, these starches contribute to greater cohesion in applications involving bricks, mortars, and joint compounds, supporting durability and efficiency in structural finishes.
Additional Applications of Modified Starches Across Industries
● Agriculture: coating seeds to improve growth rates
● Personal Care: thickening agent in lotions and creams
● Food & Nutrition: stabilizer and thickener in food products
● CASE (Coatings, Adhesives, Sealants, Elastomers): as a base in coatings and adhesives
● Textiles: Used to improve fabric handling during the weaving process.
● Paper and Pulp: Used as binders and coatings to enhance paper strength and appearance.
● Pharmaceuticals: Serve as binders in tablets and capsules, aiding controlled release of active ingredients.
● Cosmetics: Used in powders and makeup products to improve texture and absorb moisture.
● Bioplastics: Applied in the production of biodegradable plastics, especially for packaging.
