Pratiques D’utilisation Des Produits Cosmétiques et Formulation D’un Gel Hydratant A L’Aloe Vera

Abstract

Cosmetic products play an essential role in daily life by contributing to hygiene, protection, care, and beautification of the body. Their increasingly widespread use highlights the importance of cosmetology — a discipline dedicated to the study, design, formulation, and evaluation of cosmetic products, as well as the analysis of their effects and use by consumers. In this context, the present study is organized around two complementary parts: the first focuses on the cosmetic product practices of faculty students, while the second is devoted to the formulation and evaluation of a moisturizing gel. Materials and Methods A descriptive study was conducted among 140 students using an online questionnaire. The experimental approach included a preformulation stage and the carrying out of preliminary trials. This work led to the development of final formulations, which were then evaluated for their organoleptic, physicochemical, and stability characteristics. Results and Discussion The use of cosmetic products was mainly motivated by hygiene and the improvement of appearance and self-confidence. Purchases were made primarily in pharmacies and specialized stores, with composition and quality labels being the main selection criteria. Knowledge assessment showed an overall satisfactory level, with 37.14% of students demonstrating a good level of knowledge. Preliminary trials led to the development of several carbomer gel-based formulations. All developed formulations showed satisfactory stability. The formula containing 10% Aloe vera and 10% vegetable glycerin was selected following sensory evaluation. Conclusion This study highlights generally satisfactory cosmetic product usage practices and a relatively adequate level of knowledge among students of the Faculty of Medicine of Sétif. Furthermore, the developed formulation showed satisfactory characteristics, underscoring the importance of preformulation and evaluation stages in the development of a quality cosmetic product.
