Polybioskin is an international and interdisciplinary three-year research and development effort aiming to broaden the use of biopolymers in biomedical, cosmetic, and sanitary skin-contact applications.

Harnessing the extraordinary antimicrobial, antioxidant, absorbency, and skin compatibility features of biopolymers and decoupling the production of exemplary high-volume products from the depletion of fossil resources by utilising primary as well as food waste biomass, the project aims to provide functionally improved, significantly more sustainable, and price-competitive everyday products, namely baby diapers, facial beauty masks, and non-woven tissue to be used in wound dressings.

In addition, tailored biodegradability properties will make alternative end-of-life options such as organic recycling feasible for and drive the implementation of circular economy thinking in entire multi-billion euro product segments.


PolyBioSkin is focused on delivering nine core objectives:

Developing and validating a 90% or more bio-based and fully biodegradable baby diaper with a skin-compatible surface and a biopolymer-based superabsorbent core, enriched with antimicrobial and antioxidant functionalities to prevent skin reddening and inflammation.

Developing and validating a >90% bio-based, bioactive facial beauty mask, in the form of a film or a non-woven tissue impregnated with formulations based on natural compounds.

Developing a biodegradable and at least 90% bio-based nanostructured biocompatible non-woven tissue for use in wound dressings.

Assessing the skin compatibility of the developed textiles and films using ethically sustainable testing methods.

Significantly increasing the renewable content of selected personal care, cosmetic, and biomedical applications from little or no bio-based content to over 90%.

Reducing the environmental impact of the target products by improving end-of-life scenarios through eco-design.

Increasing the knowledge and understanding of smart nanotechnologies and nanomaterials as applied to biopolymers and validating them in the market.

Demonstrating both the safety and regulatory compliance and the environmental and economic sustainability of the developed processes and products.

Maximising the contribution of the project results to sustainable economic and job growth.


PolyBioSkin will focus on two main classes of bio-based polymers with excellent innovation, sustainability, and commercialisation potential for the bio-based industry: biopolyesters, specifically PLA and PHAs, and the natural polysaccharides cellulose, starch, and chitin/chitosan.

The former have excellent properties including biodegradability and biocompatibility and are available at an advanced industrial scale. The polysaccharides have unique desirable attributes including high absorbancye and antibacterial properties. Films and textiles will be produced from these polymers and their combinations to prove that key products and/or product parts in the sanitary, cosmetic, and biomedical industries can be effectively shifted from a fossil-derived to bio-based polymer base.

PolyBioSkin will apply a range of processing technologies for biopolymer development, including electrospinning, surface modification, and impregnation of films and fibres, resulting in (i) A new biodegradable diaper consisting of a bio-based topsheet with antimicrobial and skin beneficial functionalities and a bio-based superabsorbent layer; (ii) Novel cosmetic masks based on textiles or films made from biopolymers and impregnated with molecules beneficial for the skin; (iii) Nano-structured highly skin-compatible textiles for wound dressing.

Expected Impacts


“PolyBioSkin will facilitate innovation and opportunities in the circular bioeconomy, helping to place Europe in a leading position in the development of high-performance, eco-friendly biopolymers.”

Elodie Bugnicourt, H2020 Task Force Leader

“PolyBioSkin innovations will pave the way towards improved waste management practices by focussing on organic and mechanical recyclability as an alternative to incineration and landfilling.”

Simona Neri, PolyBioSkin Project Coordinator


PolyBioSkin unlocks ecological and economic opportunities by substituting conventional fossil-based materials with more sustainable bio-based alternatives in high-value market segments.

Project Phases

Phase 1: Specification Phase

WP 1  Specification of  the exact target applications and selection of suitable bio-based raw materials. This assessment will identify which materials are most efficient in terms of the desired functions as well as in terms of cost-efficiency. It will also run a pilot-scale production of polyhydroxyalkanoates (PHAs) with enhanced compatibility to human skin.

Phase 2: Laboratory Phase

WP 2 Preparation of granules from biopolymer blends and composites for producing films for topsheets and beauty masks, and fibres for textiles. This work package will also explore surface modifications of films as a method for introducing anti-microbial and anti-oxidant functions.

WP3 Production of biopolymer-based fibres. These will include modified polysaccharide-based superabsorbents for bio-based and biodegradable diapers and fem care products. WP3 will also optimise and validate the formulations developed in WP2 for textiles to be used in the facial beauty masks and wound dressings.

WP4 will examine bio-based micro and nano-structured non-woven tissue, using electrospinning of blends and nano-composites based on chitin derivatives and biodegradable polyesters for beauty masks and wound dressings.

Phase 3: Industrialisation and Impact Assessment

WP5 Prototyping and testing of a PolyBioSkin baby diaper to validate and demonstrate the production and properties of the bio-based functional topsheet and superabsorbent polymers (SAP).

WP6 will validate the production and properties of films and textiles for beauty masks and produce prototypes for testing.

WP7 Validation of the nano-structured textile-based wound dressing, scale up of production, and prototypes for testing.

Phase 4: Life Cycle Assessment and Risk Evaluation

WP8 analyses the impact of materials/products and processes on human health and the environment and will conduct LCA, LCCA, health and safety evaluations, and biodegradation assessments. It will also examine relevant standardisation and legislative/policy aspects.

Phase 5: Dissemination, Exploitation, Management and Ethics Requirements

WP9 will describe the products’ value chains and set up suitable business models to reach early adopters. It will maximise the impact of the project for growth and jobs through communication, dissemination and exploitation of the PolyBioSkin results. In addition, it will advocate the support of the PolyBioSkin solutions and ecolabels with policymakers.

WP10 covers all aspects of project management, coordinates the project components, and ensures that resources are managed effectively and that communication and reporting obligations are met, particularly with the European Commission and the BBI-JU.

WP11 will ensure the PolyBioSkin project complies with all applicable ethics requirements.


``Most commercial diapers and fem care products use polyolefin top sheets that may cause skin irritations, inflammations and even intolerances, while biopolymers offer a high degree of biocompatibility``
- Serena Danti, Scientific Manager of PolyBioSkin, INSTM
“Many cosmetic and biomedical skin-contact applications, and most commercial diapers, still rely on conventional plastic films, thus positioning at the bottom of the European waste management hierarchy. The Union of Concerned Scientists estimates that 18 billion diapers are thrown into landfills every year.”
- Simona Neri, PolyBioSkin Project Coordinator, IRIS
``PolyBioSkin will develop and validate pilot processes for producing prototypes for three globally significant, high performance, skin-contact, bio-based products: diapers, beauty masks and wound dressings``
- Elodie Bugnicourt, H2020 Taskforce Leader, IRIS
