Viabilidade de produção de álcool em gel 70%: pesquisa do curso de farmácia para enfrentamento do coronavírus

Abstract

There has been much debate regarding the COVID-19, disease caused by the SARS-CoV-2 virus, since it was considered a pandemic by the World Health Organization (WHO). Among the measures taken to prevent the propagation of the coronavirus from one person to another is the use of antiseptics, such as alcohol-based hand sanitizers. With a commercially available ready-made base, composed of acrylic copolymers and water, combined with the right amount of ethyl alcohol, is possible to produce alcohol-based antiseptic hand sanitizers. This study aimed to develop alcohol-based antiseptic hand sanitizers from a ready-made acrylic copolymer and water base and ethyl alcohol on a proof different from the stated by the producer, in a way that would enable the production and donation of those antiseptics to society through a federal university extension project. Samples were developed using 3 (three) different ethyl alcohol proof, all of them being submitted to physicochemical tests, in a span of 90 (ninety) days, such as alcohol proof, pH, viscosity, spreadability, in order to determine its efficiency as an antiseptic product. It was concluded that, although the producer's recommendations of using ethyl alcohol in proof of 96% (w/w), it is possible to achieve the same product by means of using ethyl alcohol with a proof of 91% (w/w).
