Microbiological Study of Modern Cosmetics

Cosmetic products support microbial growth due to the presence of variable amounts of nutrients.The Most bacterial contaminants that were found in cosmetic products,Staphylococcu Pseudomonas, Klebsiella, Achromobacter and Alcaligenes Mostly due to contaminated water. The  Ministry  of  Health  of  Turkey  defined  “Cosmetics  as  all  the  preparations  that  were  prepared  to  be  used  for  epidermis,  nails,  hair,  lips,  genital  organs  and  teeth  and  mouth  mucosa  and  their  only  aim is  to  clean,  give  odors,  change  the  morphological  appearance  and/or  to  regulate  the  body  odors  and  keep  them  in  good  positions” otal bacterial count, isolation and identification ofpathogenic isolates were performed on the collected cosmetics. About 10.6% of tensiolytes (13.5% bath foam, 6.7% shampoo, 10% liquid soaps) were contaminated by Staphylococcus warneri, Staphylococcus epidermidis and Pseudomonas putida. The efficacy of the preservative systems of two cosmetic products, tested against standard micro-organisms (Staphylococcus aureus ATCC 4338 and Pseudomonas aeruginosa ATCC 9027) and two isolates from cosmetics in this study (S. epidermidis and P. putida), satisfied the Cosmetics, Toiletries, and Fragrance Association and Official Italian Pharmacopeia criteria, while only one tested cosmetic respected the Rapid Challenge Test criterion. Contaminated cosmetic products are relatively uncommon, but some products, unable to suppress the growth of several micro-organisms, represent a potential health hazard.

The Ministry of Health of Turkey defined “Cosmetics as all the preparations that were prepared to be used for epidermis, nails, hair, lips, genital organs and teeth and mouth mucosa and their only aim is to clean, give odors, change the morphological appearance and/ or to regulate the body odors and keep them in good positions”. However the Federal Food and Drug Cosmetic Act criteria defined it as the articles intended to be rubbed, poured, sprinkled, or sprayed on, introduced into, or otherwise applied to the human body or any part thereof for cleansing, beautifying, promoting attractiveness, or altering the appearance, and articles intended for use as a component of any such articles; except that such term shall not include soap.
