Produtos cosméticos livres de conservantes: Associação de insumos para garantir estabilidade e segurança microbiológica

Abstract

Introduction: The growing concern among consumers regarding health and prolonged exposure to traditional synthetic preservatives, such as parabens, has driven the demand for cosmetic products considered preservative-free (PF). This movement reflects a shift in market behavior, which increasingly seeks alternati-ves perceived as safer and more natural. In this context, investigating viable substitutions for traditional preservatives becomes essential for the development of innovative formulations aligned with current consumer expectations. Objecti-ve: To present the benefits and risks of using parabens and alternative ingredi-ents for the development of new preservative-free (PF) products. Methods: An exploratory literature review was conducted using the PubMed, SciELO, Direct Science, Google Scholar databases, and the UL Prospector platform. Within the 2015–2025 timeframe, 17 scientific articles, two Collegiate Board Resolutions (RDCs), and two technical documents from manufacturers were identified. After applying eligibility criteria, 4 articles addressing paraben exposure and 9 studies on non-traditional preservative alternatives were selected. Results: Currently, published studies evaluate paraben exposure and its impacts on human health. There is significant pressure from both the media and consumers on the cosme-tics industry to create preservative-free products. Viable and proven alternatives for product preservation already exist on the market, as well as promising natu-ral-origin ingredients still under development. Conclusion: Although parabens still represent a group of more economically viable and safe preservatives, with scientific and technical support when used in accordance with current legislation, there are already alternative options available for potential substitution, in addi-tion to promising natural-origin ingredients with the same purpose, opening ave-nues for further research and innovation in the field of cosmetology.
