Abstract(s)
A crescente preocupação com a sustentabilidade e a procura por soluções alinhadas com os princípios da economia circular têm levado a indústria cosmética a explorar alternativas que permitam reduzir o desperdício e valorizar subprodutos agroindustriais. Neste enquadramento, a presente dissertação foi desenvolvida na empresa Castelbel, reconhecida pela produção de sabonetes de luxo, tendo como objetivo a valorização da casca e da coroa do abacaxi, através da sua incorporação em formulações de sabonetes líquidos e sólidos. A metodologia adotada contemplou a secagem, trituração e estabilização dos resíduos, que foram aplicados diretamente como agentes esfoliantes ou submetidos a extração por Soxhlet, utilizando n-hexano como solvente, para a obtenção de óleo da casca de abacaxi. Este extrato foi incorporado em formulações de sabonetes líquidos. No total, foram desenvolvidos oito sabonetes sólidos e oito líquidos, diferenciados pela granulometria, pelo tipo de subproduto utilizado (casca ou coroa) e pela presença ou ausência do óleo extraído. As formulações foram submetidas a ensaios de estabilidade físico-química e sensorial,
sob diferentes condições de stress (refrigeração, fotoestabilidade e estabilidade acelerada), além do controlo em condições ambiente. Os resultados evidenciaram apenas alterações ligeiras ao longo do período de estudo, como pequenas variações de pH, cor e massa, sem impacto significativo na qualidade final. Importa destacar que os valores permaneceram dentro dos limites definidos pela Castelbel: pH entre 10,0 e 11,0 nos sabonetes sólidos e entre 4,5 e
6,5 nos líquidos, garantindo a adequação fisiológica. As análises sensoriais confirmaram uma boa aceitação global, com classificações iguais ou superiores a 3 (escala de 1 a 5), demonstrando resultados satisfatórios em aroma, aparência,
textura, espuma e sensação cutânea. Apesar do baixo rendimento do óleo (1,02%), a sua extração mostrou-se tecnicamente viável. Em conclusão, os resultados obtidos validam a incorporação de subprodutos de abacaxi
em formulações cosméticas, confirmando o potencial de valorização destes resíduos e reforçando a relevância da sustentabilidade na indústria cosmética. Palavras-chave: Valorização de resíduos; cosmética sustentável; sabonetes; abacaxi; extração com solvente.
The growing concern with sustainability and the search for solutions aligned with the principles of the circular economy have led the cosmetic industry to explore alternatives that reduce waste and promote the valorization of agro-industrial by-products. Within this framework, the present dissertation was developed at Castelbel, a company recognized for the production of luxury soaps, with the aim of valorizing pineapple peel and crown through their incorporation into liquid and solid soap formulations. The adopted methodology involved drying, grinding, and stabilizing the residues, which were either directly applied as exfoliating agents or subjected to Soxhlet extraction using nhexane as solvent to obtain pineapple peel oil. This extract was incorporated into liquid soap formulations. In total, eight solid and eight liquid soaps were produced, differentiated by particle size, type of by-product used (peel or crown), and the presence or absence of the extracted oil. All formulations were subjected to physicochemical and sensory stability tests under different stress conditions (refrigeration, photo-stability, and accelerated stability), as well as ambient control. Results revealed only minor changes over the study period, such as slight variations in pH, color, and mass, without significantly affecting product quality. Notably, values remained within the limits defined by Castelbel: pH between 10,0–11,0 for solid soaps and 4,5–6,5 for liquid soaps, ensuring physiological suitability. Sensory analyses confirmed overall positive acceptance, with scores equal to or above 3 (on a 1–5 scale), reflecting satisfactory results in fragrance, appearance, texture, foam, and skin feel. Despite the low oil yield (1.02%), extraction proved technically feasible. In conclusion, the findings validate the incorporation of pineapple by-products into cosmetic formulations, confirming their valorization potential and reinforcing the importance of sustainability within the cosmetic industry.
