Dextrin

Dextrin (CAS 9004-53-9), also known commercially as E1400, is a starch-derived carbohydrate produced through partial hydrolysis or thermal treatment of starch. It functions as a binder, adhesive, thickener, and carrier across food, industrial, and pharmaceutical manufacturing.

In food production, E1400 acts as a bulking agent and encapsulation carrier for flavors, oils, and spray-dried ingredients. This improves the shelf stability and flowability of finished powders in various commercial applications.

Corrugated board, paper bag, and envelope manufacturing rely on dextrin-based adhesives for their fast-tack, water-based bonding performance. These industrial solutions provide reliable adhesion for high-speed production lines.

Textile and printing operations use it as a thickener in screen printing pastes and a sizing agent to improve fabric stiffness. This process enhances yarn processability and ensures consistent quality in textile finishing.

In pharmaceutical tablet and capsule manufacturing, it functions as a binder and diluent, supporting granulation and controlled disintegration. It is a critical component for ensuring the structural integrity of medicinal dosages.

Dextrin is supplied as a white to off-white powder, with granulated forms available for specific industrial applications. Established grades include food-grade (FCC compliant), pharmaceutical-grade (USP/BP), and technical-grade.

Conversion degree and solubility profiles vary by grade, so buyers typically specify dextrin type based on application requirements. Common varieties include white, yellow, or British gum depending on the desired chemical properties.
