Determination of microbiological control of pseudomona in eyelash mascaras in the city of Cuenca

Abstract

Introduction: Cosmetic microbiology oversees guaranteeing the safety of cosmetic products; the presence of nosocomial pathogens such as Pseudomonas should be null; however, poor control of Good Manufacturing Practices (GMP) during the manufacture of makeup can generate contamination by this microorganism and put the consumer's health at risk. Therefore, the FDA emphasizes the importance of performing microbiological tests on all products intended for human use. Objective: To determine the microbiological quality of mascaras sold in Cuenca, observing if they comply with the maximum limits allowed according to the Colombian Mandatory Health Notification (NSO, by its Spanish acronym) for Pseudomonas. Methodology: A pure experimental study was conducted on five different mascara brands, applying the guidelines given by the FDA for a microbiological analysis. The identification of Pseudomonas sp was based on identification tests performed in the laboratory. Results: Five mascara brands were analyzed, including two Ecuadorian and three imported brands. Considering that only one of the imported brands showed growth for Pseudomonas sp, this was confirmed through microbiological analysis, using culture media, specific tests, and statistical analysis of variables using IBM SPSS 26. Conclusion: Identifying Pseudomonas in the mascara brand indicates non-compliance with the NSO, indicating the application’s lack of quality and safety.
