Abstract
Este trabalho tem como objetivo investigar o potencial de compostos naturais com atividade antimicrobiana em formulações cosméticas, à luz das crescentes exigências por produtos seguros, eficazes e ambientalmente sustentáveis. Fundamentando-se em uma revisão integrativa da literatura, foram analisadas evidências científicas sobre a eficácia de óleos essenciais, extratos vegetais e peptídeos antimicrobianos no controle de microrganismos patogênicos da pele e na preservação da microbiota cutânea. A análise demonstrou que muitos desses compostos naturais apresentam mecanismos de ação seletivos, capazes de inibir microrganismos patogênicos sem comprometer o equilíbrio da microbiota residente. Além da ação antimicrobiana, destacam-se propriedades anti-inflamatórias, cicatrizantes e antioxidantes que ampliam seu valor terapêutico. A incorporação desses bioativos em cosméticos, no entanto, ainda enfrenta desafios relacionados à estabilidade, padronização e segurança, exigindo o uso de tecnologias como microencapsulação e nanopartículas. Conclui-se que os compostos naturais representam uma alternativa viável e funcional aos conservantes sintéticos, com potencial para uso isolado ou em associação sinérgica, contribuindo para o desenvolvimento de formulações mais compatíveis com a fisiologia cutânea e com as exigências regulatórias atuais.
Abstract: This study aims to explore the potential of natural compounds with antimicrobial properties in cosmetic formulations, responding to the growing demand for products that are safe, effective, and environmentally sustainable. Through an integrative literature review, we examined scientific evidence on the efficacy of essential oils, plant extracts, and antimicrobial peptides in controlling pathogenic skin microorganisms while preserving the delicate balance of the cutaneous microbiota. Findings reveal that many of these natural agents act via selective mechanisms, effectively inhibiting harmful microbes without disrupting the resident skin flora. Beyond their antimicrobial effects, these compounds also exhibit noteworthy anti-inflammatory, wound healing, and antioxidant activities, which further enhance their therapeutic appeal. Nonetheless, challenges remain in incorporating these bioactives into cosmetic products, particularly concerning their stability, standardization, and safety. Innovative delivery technologies, such as microencapsulation and nanoparticle systems, are essential to overcome these hurdles. In conclusion, natural compounds emerge as promising and functional alternatives to synthetic preservatives, either alone or in synergistic combinations, paving the way for formulations that align more closely with skin physiology and current regulatory standards.
