Castelldefels, Spain, 17 July 2017 – The EU-funded PolyBioSkin project commenced work on the development of biopolymers for high-demand skin-contact applications. At the end of June 2017, the project consortium, comprising of 12 partners, including European Bioplastics (EUBP), met in Castelldefels in Spain for the kick-off meeting hosted by project coordinator IRIS to discuss how new generation bio-based polymers can help advance sustainable alternatives in sanitary, cosmetic, and biomedical applications

The skin is the largest organ in the human body and it is our first natural barrier against external agents. Cosmetics, personal care, sanitary, and biomedical products are designed for direct contact with and protection of the skin. These products represent a very large market, ranging from low-cost to high-performance products, with a global market value of over USD 47 billion[1].

Today, most of these skin-contact products are still made from fossil-based polymers and are non-recyclable and non-biodegradable. The Union of Concerned Scientists estimates that about 18 billion diapers end up in landfills each year,[2] which poses great environmental concerns. In the light of increased competition, a growing ecological awareness, and changing consumer demands, brands are looking for more sustainable product options with a reduced environmental footprint. PolyBioSkin aims at leveraging the enormous untapped potential of the use of bio-based polymers in skin-contact product applications by advancing the research and development towards the industrial exploitation of renewable, sustainably-sourced bio-based polymers that offer unprecedented antimicrobial, antioxidant, absorbency, and skin compatibility properties and functionalities for skin protection and sustainability in three strategic target markets: sanitary, cosmetic and biomedical.

PolyBioSkin will focus on two main classes of bio-based polymers: (a) polysaccharides (cellulose, starch and chitin/chitosan), which the project aims to derive from waste feedstocks, and which are chosen for their biodegradability and peculiar functional properties, such as absorbency and anti-infectivity, and (b) biopolyesters, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHAs), which are 100% based on renewable resources and also biodegradable.

Over the next three years, PolyBioSkin will develop and validate:

  • a biodegradable diaper provided with a skin-compatible surface enriched with anti-microbial and anti-oxidant functionalities to prevent skin reddening and inflammation, and with a biopolymer-based superabsorbent;
  • a biodegradable and bioactive facial beauty mask based on biopolymers in the form of a film or a non-woven tissue impregnated with formulations based on natural compounds beneficial for the skin;
  • a nanostructured biocompatible non-woven tissue to be used in wound dressings.

The developed products aim to have a content of renewable materials of 90%, feature a reduced environmental footprint, and provide improved end-of-life options. An LCA and LCCA will be performed to demonstrate the products’ environmental and economic sustainability, and compliance with safety and regulatory requirements will be demonstrated.

The European bioeconomy sectors are worth EUR 2.2 trillion in annual turnover and account for around 20 million jobs, which is 9% of the EU’s workforce[3]. Bioplastics have been designated a lead market by the European Commission, expected to grow at CAGRs of 17.5% or more between 2016-2020[4]. The PolyBioSkin consortium combines t
