Résumé:
Since antiquity it has been reported the use of substances that gives antimicrobial action. The sanitization process can be physical and / or chemical and has the function of reducing the level of contamination by microorganisms and toxic proteins in inanimate objects, being the disinfectant one of the products most used for disinfection of environments and its effectiveness is based on the capacity Reduce the level of contamination. In Brazil, the increasing use of disinfectants has brought greater responsibility for its regularization, and the National Sanitary Surveillance Agency is responsible for approving and supervising these products in order to guarantee quality and safety. The objective of this study was to evaluate the physico-chemical parameters (pH, foam index and centrifuge test) and the efficacy of disinfectants against the samples of Aspergillus niger, Candida albicans, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus. In this study, two disinfectants of national scope and two disinfectants of local scope (Ceará and Paraíba) were tested. After the tests, all disinfectants complied with the centrifuge test and foam index. The samples B, C and D showed the pH in the microbial growth range ((7.6 a 8.2), showing no relation with antimicrobial efficacy. No efficacy of locally available products was proven, and nationally available disinfectants were not able to inhibit the growth of Aspergillus niger, Candida albicans and Pseudomonas aeruginosa.
