Isosorbide, a green plasticizer for thermoplastic starch that does not
Isosorbide allows some technological advantages with respect to classical plasticizers: namely, direct mixing with starch, energy savings for the low processing temperature required and lower water uptake. Indeed, maize starch was directly mixed with the solid plasticizer and direct fed in the main hopper of a co-rotating twin screw extruder.

The addition of isosorbide to starch allows a good plasticization and does not exhibit any problem regarding thermal degradation before 200 °C, as well as any common plasticized starch. The mechanical properties of starch plasticized with isosorbide depend on water content thus related to the air relative humidity.
Isosorbide, a green plasticizer for thermoplastic starch that does not
Recently, isosorbide has been tested as a novel, effective and green plasticizer for starch due to its biodegradability and no toxicity, which prevents the starch retrogradation [4, 5].
Properties and behavior under environmental factors of isosorbide
Two plasticizers were used: isosorbide (C6 H 10 O 4, with a purity of 98%, melting point of 60 °C and molar mass of 146.14 g·mol 1) purchased to Acros Organics (Spain) and glycerol (C 3 H 8 O 3, purity >99.5%, melting point of 18 °C and molar mass of 92.09 g·mol 1) supplied by Sigma-Aldrich (Spain).

- Can isosorbide be used for preparing Thermoplastic starch?
- It can be used for preparing thermoplastic starch through a semi-industrial process of extrusion. Isosorbide allows some technological advantages with respect to classical plasticizers: namely, direct mixing with starch, energy savings for the low processing temperature required and lower water uptake.
- Is isosorbide a biodegradable diol?
- Isosorbide is a non-toxic biodegradable diol derived from bio-based feedstock. It can be used for preparing thermoplastic starch through a semi-industrial process of extrusion.
- Can epoxidized isosorbide ester be used as a heat stabilizer?
- Epoxidized isosorbide ester can be used as a heat stabilizer. The authors declare that they have no conflict of interest. Abstract Plasticizers are widely used in poly (vinyl chloride) (PVC), polylactic acid (PLA), thermoplastic starch (TPS), and other modified powder materials to enhance the flowability, flexibility, ...
- What are the advantages of isosorbide?
- Isosorbide allows some technological advantages with respect to classical plasticizers: namely, direct mixing with starch, energy savings for the low processing temperature required and lower water uptake. Indeed, maize starch was directly mixed with the solid plasticizer and direct fed in the main hopper of a co-rotating twin screw extruder.
- Is isosorbide enough to plasticize starch?
- Both isosorbide and other plasticizers are adequate to plasticize the starch under the processing conditions used. However, thermoplastic starches have shown a certain crystallinity known as processing-induced crystallinity. It is attributed to the crystallization of amylose chains complexed with plasticizers into single-helical structures.
- Are cardanol- and isosorbide-based plasticizers a promising material?
- Among a variety of newly developed biobased monomers, cardanol, and isosorbide are the two most promising materials because of their unique structural features. This review summarizes the research progress of cardanol- and isosorbide-based plasticizers with synergistic effects of plasticization, thermal stabilization, and anti-migration.
