防腐体系的配方删选
Preservative System Formula Selection

可对客户提供的化妆品防腐体系，以微生物挑战性试验进行防腐效能评价，对体系内配方进行删选，建立合理的防腐体系，使化妆品免受微生物的污染。 
We could evaluate the preservative efficacy of the cosmetic preservative system provided by customers through microbial challenge tests, optimize the formulas in the system, and establish a reasonable preservative system to protect the cosmetics from microbial contamination.
