ABSTRACT

This study was aimed at determining the microbiological quality of some brands of locally produced cosmetics powders sold within Umuahia metropolis. A total of thirty (30) samples; fifteen (15) each of baby powder and adult powder with different manufacturing dates were randomly purchased in different markets in Umuahia, Abia State transferred to the laboratory and analysed. A 10 fold serial dilution was carried out followed by plating using standard spread plate method. From the result, it was observed that all the products were contaminated, having total viable count ranging from 3.50x106 – 1.35x107 cfu/ml for the adult powder and 4.90x106 – 1.37x107 cfu/g for the baby powder. Bacteria isolated from the adult powder were Staphlococcus spp 48%, Micrococcus spp. 4%, Streptococcus spp. 19%, Bacillus spp. 6%, Escherichia coli were not isolated from any of the adult powders. While bacterial isolates from the baby powders include Bacillus spp. 15%, Escherichia coli 4%, Micrococcus spp. 15%, Staphlococcus spp 39%, Streptococcus spp. 27%. Fungal isolates from the adult powders were Candida spp. 24%, Penicillium spp. 14%, Aspergillus spp. 33%, Rhizopus spp. 29% while fungal isolates from the  baby powders were  Rhizopus spp. 30%, Aspergillus spp. 30%, Trichoderma spp. 15%, Penicillium spp. 7%, Candida spp. 18%. From this study, it was established that these products analysed were more contaminated with bacteria than fungi. And also the baby powders studied are found to be more contaminated than the adult powders.T herefore, good manufacturing practices and hygiene must be carried out by manufacturers and personnel, water must be tested continuously for microbial growth, raw materials should be tested before use especially those of natural origin and cosmetic products should be stored in an aseptic environment to avoid contamination before vendinig in the markets.
