Upcycling na indústria cosmética: uma análise da utilização da lignina como ingrediente cosmético

Abstract

In the cosmetic sector, there is a growing trend towards the development of products that are more durable, more efficient and more sustainable. In this context of innovation and sustainability, there is the practice of upcycling, which proposes a new way of transforming and using discarded materials or by-products. Thus, these materials gain a new purpose, increasing their useful life and bringing a new use before the end of their life cycle. The pulp and paper industry has numerous residues, by-products and effluents, and among them is lignin, which has already been used as an additive in cosmetics. This work aims to address the theoretical aspects using the Methodi Ordinatio to carry out a systematic review aligned to the theme, 10 articles were selected relating the use of lignin in cosmetics, a search for patents was also carried out in order to find out if there were already inventions where lignin used for the production of cosmetics. Through the selected studies, we can see that the subject is constantly evolving, lignin is already widely used for the production of antioxidants and sunscreens, and despite the term upcycling being relatively new, it is already inserted in areas such as cosmetics, showing the great possibilities of reusing lignin for skin care products.
