Avaliação da qualidade microbiana de pós cosméticos.

Abstract

Microbial quality is one of the preconditions of a cosmetic product, considering that the presence of viable contaminants and pathogenic in addition to cause changes in the formulation, as loss of efficacy and undesirable aspect, may establish risk to consumer health. The cosmetic products are known to be substrates for the survival and development of a wide variety of microorganisms, this fact highlights the need of Good Manufacturing Practices (GMP) which are key requirements for quality cosmetic product assurance. So, this study aimed to evaluate the microbiological quality of cosmetic facial use in powder presentation in use, through the viable microorganisms count method, as well as identify the possible pathogens presence such as Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. The results showed that only one sample presented all the information required for the mandatory labeling of primary packaging and the expiration date required in secondary packaging. The total viable counts count showed that all products surveyed were within the parameters established by the Brazilian Pharmacopoeia (2010), no more than 10 ³ CFU / g or ml, maximum 5 x 10 ³ CFU / g or ml. However, the E. coli presence in three samples and S. aureus in a sample was identified among the five samples studied. Based on these results, we highlight the importance of guidance and care in the handling of cosmetic products by the consumer, since the presence of microorganisms, known pathogens represents contamination risk, especially in relation to impaired people who have low immunity or have same allergies type.
