The antisepsis of the hands of food handlers can be considered a fundamental aspect for the reduction of microbial flora present in the food processing environment, thus ensuring food security. In this context, the search for natural products with antimicrobial activity has motivated us to conduct researches to develop phytocosmetics or sanitizing formulations that can be used in the food industry and food services, in order to reduce the incidence of diseases transmitted by food and impairment losses. Allamanda cathartica L. specie belonging to the family Apocynaceae, also known as yellow allamanda, is native to the Brazilian Atlantic Forest. It has flavonoids and coumarins, among other main secondary metabolites, possibly responsible for its pharmacological activity. The antimicrobial activity of glycolic extract of Allamanda cathartica L. (GEAC) and the activity of the antiseptic liquid soaps containing its extracts were evaluated by agar diffusion method and by the evaluation of the activity for simulated use of the product. Both the GEAC, as the liquid soap containing the same extract showed inhibitory activity against Staphylococcus aureus and Escherichia coli in the agar diffusion test. The simulated use of the the liquid soap containing GEAC showed similar results to the positive control represented by a liquid soap containing 1% triclosan. The analysis results showed satisfactory decimal reduction levels front of the same bacterias. The product was also evaluated for its physical and chemical stability during 60 days of analysis and subjected to five different temperatures, showing stable with respect to pH, density, viscosity, appearance, color and odor, with a coefficient of variation less than 10%, in terms of average values for the variables described.
