Formulación de productos cosméticos con aceite de semillas de Cucurbita argyrosperma C. Huber

Formulation of cosmetic products from Cucurbita argyrosperma C. Huber seed oil

El presente trabajo tiene como objetivo aprovechar el aceite de las semillas de Cucurbita argyrosperma C. Huber (sin. Cucurbita mixta Pangalo), como fitoingrediente en la elaboración de productos cosméticos. El aceite empleado se obtuvo por extracción con soxhlet y se realizó su caracterización fisicoquímica. Se elaboraron emulgeles (O/W) variando el agente viscosante y emulgente. Las formulaciones logradas se valoraron mediante la evaluación de las propiedades organolépticas (color, olor, brillo), fisicoquímicas (pH, conductividad) y extensibilidad y fueron sometidas a estudios de estabilidad. Se obtuvieron productos tipo emulgel de color amarillento con ligero olor ceroso, con pH aceptable para la piel. Todas las formulaciones resultaron estables. Los resultados demostraron que las formulaciones propuestas permitieron incorporar el aceite de origen vegetal logrando un preparado cosmético de características y estabilidad aceptables.

The objective of this work is to take advantage of the oil of the seeds of Cucurbita argyrosperma C. Huber (sin. Cucurbita mixta Pangalo), as a phytoingredient in the elaboration of cosmetic products. The oil used was obtained by extraction with soxhlet and its physicochemical characterization was carried out. Emulgels (O/W) were prepared by varying the viscosifying and emulsifying agent. The formulations achieved were evaluated by evaluating the organoleptic properties (color, odor, brightness), physicochemical (pH, conductivity) and extensibility and were subjected to stability studies. Emulgel type products with yellowish color with slight waxy odor were obtained, with acceptable pH for the skin. All the formulations were stable. The results showed that the proposed formulations allowed incorporating the oil of vegetable origin achieving a cosmetic preparation of acceptable characteristics and stability.
