Dextrins and other modified starches (e.g. pregelatinised or esterified starches); glues based on starches or on dextrins or other modified starches
In plain English
This category includes dextrins and other starches that have been altered, such as those that are pregelatinised or esterified. It also covers adhesives made from starches, dextrins, or these modified starches. The items are split into two groups: one for the dextrins and modified starches themselves, and another for the glues based on these materials.
