Introduction: The care for physical appearance represents a priority aspect for people of different age groups, so it is necessary to have safe and economically accessible cosmetics for the population, which also allow to revalue the use of products derived from plant species.
Objective: Develop a lipstick made from the fruit of Gaultheria glomerata (Cav.) Sleumer for cosmetic use.
Methods: A quantitative and applied study was carried out in two stages. In the first stage, the ethanolic extraction of the dye of the fruit of Gaultheria glomerata (Cav.) Sleumer was carried out with the respective quality controls; and in the second stage, using the hot method, a lipstick was designed and formulated with the natural dye. The cosmetic product obtained was subjected to organoleptic (odor, brightness, appearance, color, slippage, texture and adhesion), physicochemical (pH, peroxides index, melting point and softening point) and microbiological (aerobic mesophiles, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli) controls. The shelf life was estimated through accelerated stability and shelving studies. Descriptive and inferential statistics were used for quantitative data considering a reliability level of 95%.
Results: The extract of the fruit of Gaultheria glomerata (Cav.) Sleumer was liquid, fluid, with purplish color, with slightly pleasant smell, pH 5.5/0.1 and density of 1.04/0.0 g/mL; the developed formulation presented constant organoleptic characteristics: very shiny, uniform, optimal appearance, pleasant smell and good adhesion; with physicochemical characteristics, pH, peroxide index, melting point and softening within the standard specifications, without significant changes over time; and, in the microbiological characteristics, it had absence of microorganisms. The shelf life of the formulation was 1.5 years according to accelerated stability and shelf studies.
Conclusions: The lipstick made from the dye of Gaultheria glomerata (Cav.) Sleumer presents cosmetic quality, by complying with organoleptic, physicochemical, microbiological and stability controls and represents in the short, medium and long term an entrepreneurial strategy for those organizations that are interested in manufacturing cosmetic products.
