Abstract
The development of circular products in the cosmetics sector necessitates a rethinking of design and production
processes to ensure both consumer safety and environmental sustainability.
This study introduces an enhanced Quality Function Deployment (QFD) framework that integrates circular
economy principles into product design. Applied to a case study on an innovative, lignin-based sunscreen, the
model demonstrates how circular criteria can be systematically incorporated into decision-making. The findings
highlight that the proposed QFD-QCC approach improves alignment between customer needs, technical feasibility,
and sustainability performance. It enables designers to prioritise interventions that optimise resource use,
reduce production costs, and enhance environmental outcomes.
Overall, the proposed framework provides a practical and replicable tool for integrating circularity into sustainable
product design, offering insights applicable beyond the cosmetics industry.
