APK enables the use of plastic recyclates in cosmetic packaging

Increasing recycling quotas, potential mandatory use of recycled plastics in products across the EU market and a recently published Chemicals Strategy for Sustainability pushing strongly for a toxic-free environment: the European Commission has piled up a number of demanding challenges to the plastics and packaging value chains. However, bridging the gap between increased use of recycled plastics and attainment of the performance required for specific packaging applications can be facilitated by driving innovation in both design and technology. APK’s Newcycling® process with its physical, solvent-based recycling technology generates plastic recyclates of close to virgin quality, which are suitable to be used in cosmetic packaging.

“APK is committed to filling the gap between the quality of recyclates and product requirements and to achieve circularity for packaging”, affirms Klaus Wohnig, CEO, APK AG. Against this backdrop, APK mandated a detailed risk assessment and two toxicological evaluations for its Mersalen® LDPE NCY recyclates. The analysis of the random recyclate samples confirmed the higher level of purity and attested to both the fulfilment of REACH requirements and conformity to the provisions set out in the General Product Safety Directive as well as in the Regulation on Cosmetic Products.

Besides PET-recyclates from drinking bottles most recycled plastics do not yet feature food contact approval. And also for cosmetic packaging only few suitable recyclate is available. Requirements are ambitious, as the packaged products do come into direct contact with the human body. If virgin plastics are to be replaced with secondary raw materials, quality standards for the use of recycled plastics in cosmetic packaging need to be defined and implemented through innovative recycling technology.

As a recycling company, APK adheres to waste legislation. However, as a manufacturer of products such as the Mersalen® LDPE NCY recyclates, APK also operates within the scope of chemicals and products regulations and provides its clients with a REACH declaration.

Currently, APK uses pre-consumer LDPE/PA multilayer films as input material for the Newcycling®process. The renowned testing company Eurofins performed a comprehensive migration analysis based on random samples of Mersalen® LDPE NCY recyclates as well as on various pre-consumer input materials. Specific migration tests confirmed that Mersalen® LDPE NCY recyclates feature a decisively higher level of purity than recyclates from standard mechanical recycling.

Based on the risk assessment, two human toxicological risk evaluations were performed in 2020 by two independent toxicology experts. The purpose was to evaluate the use of Mersalen® LDPE NCY recyclate types for flexible (films) and rigid (bottles) packaging applications for cosmetics such as creams (leave-on scenario) and shampoos (rinse-off scenario) as well as various personal hygiene  products (e.g. sanitary towels, wet wipes, diapers, and toilet paper), all in contemplation of use by adults and for children and babies. Both evaluations concluded that Mersalen® LDPE NCY recyclates are of appropriate quality and can safely be used for the applications mentioned. In addition, the evaluations specified that any health problems or diseases in adults, children, and infants caused by listed non-intentionally added substances could be completely excluded.

‘To strengthen statistical representativity, APK will continue to analyse and develop the purification potential of its advanced physical solvent-based process Newcycling® with regard to different pre- and post-consumer materials”, says Hagen Hanel, Head of Research and Development at APK. The ultimate aim is to achieve food contact approval for Mersalen® LDPE NCY recyclates in the midterm.
