Item Desarrollo y evaluación de una formula cosmética de fabricación artesanal de forma barra jabonosa a base de peróxido de benzoílo para la limpieza y el control del acné(Universidad Santiago de Cali, 2025-09-29) Quintero Hincapié, Henry Mauricio; Ramírez Rico, Diana Carolina; Miller Peluffo, Jhon Alexander (Director); Ciro Monsalve, Yhors Alexander (Director)Benzoyl peroxide has established itself as an effective therapy for the treatment of acne since its discovery in 1929. Currently, it is available in various commercial presentations, such as creams, gels, soap bars and syndets, which allows it to be adapted to the needs and preferences of each user. In order to offer an innovative and practical option, a cosmetic formula in the form of a bar containing 2.5% benzoyl peroxide was developed and evaluated. This product is specially designed for those who seek to care for and maintain adequate control of acne-related disorders, providing an effective and convenient alternative for their daily care routine. Three prototypes of 2.5% benzoyl peroxide sticks were developed using different solvents: 96% potable ethyl alcohol, propylene glycol and glycerin. These prototypes were subjected to extensive analysis to evaluate organoleptic (color, odor and appearance), physicochemical (pH, moisture content and free alkali content) and microbiological quality parameters. Tests were conducted under natural stability conditions, with a temperature of 30 ± 2 °C and a relative humidity of 75 ± 5%, at intervals of 0, 15 and 30 days, using samples packed in cardboard folding cartons. The results showed that there were no significant changes in color, odor, pH, free alkali content or bacterial growth in any of the prototypes. However, slight variations in moisture and texture of the bars were observed. These findings confirmed that, under controlled conditions of temperature (30 ± 2 °C) and relative humidity (75 ± 5%), the benzoyl peroxide cosmetic bar made with alcoholic solvent and packaged in cardboard folding carton maintained its stability during the 30 days evaluated, complying with the established quality parameters. This study supports the viability of this formulation as an effective and stable option for acne care.Item Obtención del extracto de aloe vera e incorporación en una base líquida de maquillaje, para la protección, hidratación y cuidado de la piel(Universidad Santiago de Cali, 2025) Aldana Wilches, Paula Andrea; Hernández Caro, Gerson Julián; Ciro Monsalve, Yhors Alexander (Director); Miller Peluffo, Jhon Alexander (Director)The current cosmetics industry offers product lines on the market that lead women to use cosmetics, which directly affect the skin due to the variety of chemical components used in their formulation. The main unwanted effects on the skin due to makeup are the appearance of acne, dermatitis, premature wrinkles, among others, generating deterioration of the skin. In view of this current problem, a liquid makeup base with Aloe Vera extract is offered that provides a series of benefits to the skin, including reducing the risk of damage due to the presence of harmful compounds. In the present research work, it was possible to verify that Aloe Vera extract contains 31.81 mg/100mL of polysaccharides expressed as glucose equivalent and antioxidant activity both in the pure extract (28,37% ± 2,74%) and in the 70% diluted extract (29,85% ± 2,91%). However, it did not present antioxidant activity in the finished product (makeup base with Aloe Vera extract).
