Is POLYSORB® isosorbide safe?

Yes. POLYSORB® isosorbide is registered in global chemical inventories like Reach or ToSCA and the toxicological assessment has shown isosorbide was safe, without any classification.

It is free of bisphenols (like BPA, BPS or BPF), no endocrine disruptive effect has been shown and in-vitro testing on other isosorbide esters had no effect.
Performance materials - Safety

Are POLYSORB® isosorbide-based plastics BPA-free?

POLYSORB® isosorbide does not contain any Bisphenol A and so is BPA-free.

Plastics based on isosorbide are produced with co-monomers. It is recommended to contact the resin manufacturer to have more information on it.

Is PEIT (polyethylene-co-isosorbide terephthalate) a food contact polymer?

In Europe, isosorbide is listed as monomer that can be used to modify PET on "plastic materials and articles intended to come into contact with food" regulation.

Performance materials - Safety

Are all POLYSORB® isosorbide-based plastics approuved for food contact?

Food contact regulation depends both on country regulation and plastic type.

It is recommended to contact the resin manufacturer to have more information on it.

How does Roquette provide Phthalates Alternatives?

Roquette offers POLYSORB® ID, a safe plant-based general purpose plasticizer that can be used to replace phthalate-based plasticizers, such as DINP.

What can be done to increase the glass transition temperature (Tg) of polyethylene terephthalate (PET)?

Polyethylene terephthalate (PET) glass transition temperature limits its use, notably in packagings subject to heating.

By introducing POLYSORB® isosorbide as co-monomer during the resin synthesis, PEIT (polyethylene-co-isosorbide terephthalate) resin is created. POLYSORB® isosorbide introduction boosts resin temperature resisitance, enabling the use of PEIT in new demanding packaging applications.

What is POLYSORB® isosorbide impact on polymer glass transition temperature (Tg)?

Thanks to its original molecular design, POLYSORB® isosorbide often increase polymer Tg.

How can POLYSORB® isosorbide contribute to replace standard polycarbonate?

Using POLYSORB® as co-monomer in polyester resins like PET enables to create better performing materials.

With such improvement, they can pretend to be a BPA-free, safe plastic alternative to standard polycarbonate.
Performance materials - Polymer performance

Are POLYSORB® isosorbide-based polymers UV resistant?

Thanks to its non-aromatic (cycloaliphatic) structure, POLYSORB® isosorbide does not introduce into polymers UV sensitive bonds, enabling higher UV resistance to plastics.

What is the difference between standard polycarbonate and POLYSORB® isosorbide-based polycarbonate?

Standard polycarbonates are mainly composed of Bisphenol A, while by using POLYSORB® isosorbide, resin manufacturers can design special BPA-free polycarbonates.

Is POLYSORB® ID a bio-based plasticizer?

Yes. POLYSORB® ID is designed from POLYSORB® isosorbide and plant-based fatty acids, both coming from plant-based raw materials.

What is the resin identification code (RIC) for isosorbide-based plastics?

Isosorbide can be used to make different types of plastics/resin, so there is no specific RIC for isosorbide-based plastics.
Performance materials - About isosorbide

Does the "7" resin identification code on plastic mean they contain POLYSORB® isosorbide?

No. It means that the resin does not belong to the other types of resin defined from categories 1 to 6 (PET, HDPE, PVC, LDPE, PP, PS).
