Qualidade microbiológica de cosméticos industrializados: estudo experimental com bases faciais líquidas

Abstract

Introduction: Due to the daily increasing introduction of cosmetics on the market, some microorganisms inevitably go unnoticed at low levels of contamination. Objective: This work aims to carry out microbiological analyzes of liquid and industrialized cosmetic facial bases. Methods: Eleven samples of liquid facial foundations from different cosmetic industries, commercialized in Goiânia-GO, were acquired. The liquid facial was analyzed following a methodology adapted from the Brazilian Pharmacopoeia and RDC of ANVISA number 481, of September 23, 1999, as provided for the microbiological control of cosmetic products. The analysis consisted of research and the total count of the mesophilic total aerobic microorganisms, total coliforms, thermotolerant, molds and yeast, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. All tests were performed in duplicate, using the superficial sowing method. Results: Regarding the investigation of S. aureus, P. aeruginosa, E. coli and coliforms, negative results were observed in the 11 (100.0%) samples analyzed. However, in two (18,2%) samples a total count of aerobic mesophilic microorganisms was observed above the limit allowed by Brazilian legislation, which is from 5x102 UFC/g. Mycological analyzes revealed fungal growth in 10 (90.9%) of the samples, although they were with the count below the limit minimum considered acceptable by ANVISA. Conclusion: The present study highlighted the need to guarantee the quality and hygiene of industrialized liquid facial cosmetic foundations. Most of the samples showed adequate microbiological quality control, however, it is worth emphasizing the importance of the adoption of improvements by the industries regarding compliance with good manufacturing practices.
