Abstract(s)
O crescente interesse por cosméticos naturais e biológicos nas últimas décadas reflete uma maior consciencialização dos consumidores em relação às questões de saúde e ambientais. Em 2022, o mercado global de cosméticos foi avaliado em 296,83 mil milhões de dólares, sendo projetado que atinja os 474 mil milhões até 2030, com uma taxa de crescimento anual composta (CAGR) de 6,03% entre 2023 e 2030.
À medida que a sustentabilidade e a ecologia se tornam centrais no discurso público, cada vez mais consumidores optam por “cosméticos verdes”, produtos desenvolvidos com responsabilidade ambiental. Estas escolhas são motivadas não só por preocupações ecológicas, mas também pela crença de que os produtos naturais podem ser mais seguros para a saúde. Esta mudança revela uma vontade de conciliar o cuidado pessoal com a consciência ambiental, procurando reduzir a poluição sem comprometer a eficácia dos
produtos cosméticos.Contudo, a verdadeira eficácia dos ingredientes naturais presentes nestes produtos continua a ser objeto de debate.
Esta dissertação tem como objetivo avaliar a eficácia dos ingredientes naturais utilizados em produtos cosméticos biológicos. Começa por apresentar os aspetos teóricos e regulamentares dos cosméticos orgânicos, seguindo-se uma exploração dos ingredientes naturais mais comuns e das suas propriedades. Em seguida, são descritos os métodos utilizados para avaliar a eficácia cosmética, que servem de base para uma análise comparativa da eficácia dos ingredientes naturais em diversas aplicações cosméticas. A investigação aborda ainda fatores que influenciam essa eficácia, como a concentração, a formulação e a estabilidade dos ingredientes. Por fim, são discutidos os desafios atuais e as perspetivas futuras do setor, destacando oportunidades de inovação e melhoria.
Este estudo procura oferecer uma visão crítica e objetiva sobre o potencial e os limites dos ingredientes naturais em cosméticos biológicos, contribuindo para uma melhor compreensão da sua eficácia na indústria cosmética moderna, em resposta à crescente procura por produtos eficazes e ambientalmente responsáveis.
Concluiu-se que os cosméticos biológicos apresentam potencial real em termos de tolerância cutânea e impacto ambiental, especialmente devido a certas propriedades dos ingredientes naturais, como a ação antioxidante ou calmante. No entanto, a sua eficácia não pode ser generalizada e depende de múltiplos fatores, como a formulação e o processo de extração. Este estudo mostra que, embora os cosméticos biológicos não se revelem superiores de forma sistemática aos convencionais, constituem uma via promissora e complementar, desde que baseados em provas científicas sólidas e inovação sustentável.
The growing popularity of organic and natural cosmetics over recent decades reflects increasing consumer awareness of health and environmental concerns. In 2022, the global cosmetics market was valued at $296.83 billion and is projected to reach $474.00 billion by 2030, with a (CAGR) of 6.03% between 2023 and 2030. As sustainability and ecology become central to public discourse, more consumers are turning to "green cosmetics", products developed with environmental responsibility in mind. These choices are driven not only by ecological concerns, but also by the belief that natural products may be safer for personal health. This shift reveals a desire to combine self-care with environmental consciousness, aiming to reduce pollution without compromising product effectiveness. However, the actual effectiveness of natural ingredients in these products remains a subject of under debate. This thesis aims to evaluate the efficacy of natural ingredients used in organic cosmetic products. It begins by outlining the regulatory and theoretical aspects of organic cosmetics. Followed by an exploration of the most common natural ingredients used and their properties. Methods used to assess cosmetic efficacy are then presented, serving as the foundation for a comparative analysis of the efficacy of natural ingredients in various cosmetic applications. The research also examines factors influencing the efficacy of these ingredients, such as concentration, formulation, and stability. Finally, current challenges and future perspectives for the sector are examined, highlighting opportunities for inovation and improvement. This study aims to provide a critical and objective view of the efficacy of natural ingredients in organic cosmetics, thereby contributing to a better understanding of their potential and limitations in the modern cosmetics industry, in response to the growing consumer demand for effective yet environmentally responsible products. Thus, it can be concluded that organic cosmetics have real potential in terms of skin tolerance and environmental impact, especially due to certain properties of natural ingredients, such as their antioxidant or soothing action. However, their effectiveness cannot be generalised and depends on multiple factors, such as the formulation and extraction process. This study shows that although organic cosmetics are not systematically superior to conventional cosmetics, they are a promising and complementary route, provided they are based on solid scientific evidence and sustainable innovation.
