The project aims to develop a bio-based UV protection material from lignin for use in polyurethane construction foams and as a UV filter in cosmetic products such as sunscreens. UV radiation degrades foam surfaces, reducing insulation and sealing performance, while the cosmetics industry seeks safer, more sustainable UV filters.
The research focuses on chemical modification of lignin, a by-product of the wood and peat industries, to create an effective UV-absorbing additive or coating. Its performance in construction materials and cosmetic formulations, including durability and safety, will be evaluated.
The expected result is a sustainable UV additive that extends product lifetime, reduces reliance on synthetic stabilizers, and increases the value of local bioresources, supporting circular economy and greener production.
