Aloe vera (Aloe barbadensis Miller), which belongs to the Liliáceas family, is popularly used in the cosmetic, food and pharmaceutical industry. Many works demonstrated that the Aloe vera gel possesses the property of healing wounds, ulcers and burnings. Its use as a medicine has been limited due to its short shelf life. Ethanol gel is used as a very effective antiseptic agent. Objective: to evaluate the efficiency of the hydroalcoholic gel supplemented with Aloe vera extract intended as a sanitizing agent. A glycolic extract was obtained from Aloe vera leaves. Fifteen formulations of hydrogels were obtained using different proportions of carbopol, ethanol and glycolic extract from Aloe vera extracts. Pharmacotechnical and microbiological tests were performed. The efficiency of the formulations was tested on workers from a lemon packaging factory. The glycolic extract from Aloe vera leaves tested against Gram (+) and Gram (-) bacteria has demonstrated to be active. Out of the fifteen formulations tested, nº 12 demonstrated to be the most active due to the concomitant action of ethanol (60%) and glycolic extract (5%) compared to a standard hydroalcoholic gel used as a sanitizing agent.
