abstract: 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.
