description: ABSTRACT  Serum is a product that contains a higher concentration of active ingredients than   other cosmetics. Microbiological quality is very important to note. The purpose of this   research is to test the microbial contamination from a product with the Total Plate Count   method. The experiment was done over the course of 8 weeks with intervals at week 0, week   4, and week 8. The experiment was tested in 4 formulas with different concentration of   preservatives. Formula 1 without preservative (catechin 0,05%), formula 2 (cathechins 0,05%   and neolone PH100 0,9%), formula 3 (cathechins 0,05%, neolone PH100 0,6% and methyl�paraben 0,1%), formula 4 (cathechins 0,05%, neolone PH100 0,6% and methyl-paraben   0,2%). The results show that all formulas of Catechin Gambir serum spray both containing no   preservatives and containing preservatives are physically stable through parameter   organoleptic, pH, homogeneity and viscosity. All formulas qualified the requirements of the   microbial contamination test according to BPOM not more than 104  for 8 weeks. The lowest   Total Plate Count compare to other formulas that is 1,6x102  in formula 4 week 8, and the   highest Total Plate Count that is 6x102  in formula 1 week 8.  Keywords : Serum, Spray, Cathechin, Preservative, Total Plate Count.
