Análise comparativa de polímeros utilizados em embalagens cosméticas: bioplásticos, polímeros reciclados e suas propriedades de barreira e durabilidade

Abstract

This research project aims to comparatively analyze the performance of polymers used in cosmetic packaging, with an emphasis on bioplastics and recycled polymers, based on their barrier properties and durability. The study will be conducted using a qualitative, exploratory, and bibliographic approach, with data collected from recognized scientific databases. The functional, aesthetic, and environmental requirements for packaging in the cosmetics sector will be investigated, as well as the physicochemical properties of the materials analyzed. Based on this, a technical comparative analysis will be carried out using parameters extracted from the literature, such as gas permeability and mechanical resistance, in order to evaluate the technical and sustainable feasibility of these materials as alternatives to conventional plastics. It is expected that the results will support more informed material selection and contribute to the adoption of practices aligned with the circular economy in the cosmetics sector.
