Abstract
In recent years, there has been increasing interest in home-made cosmetics products in the beauty industries in Malaysia. Their escalating sales have encouraged many local producers to introduce homemade cosmetics to consumers. However, some homemade cosmetic products available in the market come without proper labelling, and list of ingredients lead to the risk of exposure to cosmetics contaminants. In addition, many risks of contamination are still unknown and yet to be discovered. The objectives of this study were to assess the level of microbiological contamination of local home-based cosmetics and to evaluate the presence of Pseudomonas aeruginosa in facial serum samples. Four different commercially available local home-based cosmetic products namely tomato serum, turmeric serum, and two whitening serums were analyzed for their microbial activity and various contamination of different bacteria specifically P. aeruginosa. Four cosmetic samples and the CFU count of the bacterial colonies' presence will be analyse and calculated. Based on this study, the results indicated that all samples were contaminated with bacteria to varying degrees. The pour plate method on Trypticase Soy Agar (TSA) and Cetrimide Agar (CA) revealed that some of the samples was contaminated by P. aeruginosa and other bacteria possibility by cross-contamination during the production process. Generally, cosmetic serum samples tested did not follow the National Pharmaceutical Regulatory Agency's (NPRA) guidelines for microbiological limits, which brings negatively impact the health status of customers and the quality of the products.
