Preservative Efficacy Test (PET) for Cosmetic Products
Preservative efficacy test (PET) is used to ensure that preservatives added to cosmetics are effective in preventing or inhibiting microbial contamination. PET is a necessary test in cosmetic research and development, Creative BioMart Microbe, as a leader in the field of microbial technology services, provides efficient PET services to customers in the cosmetic industry.
Preservative Efficacy Test
During the production and use of cosmetics, the introduction of microorganisms may lead to product deterioration, which will not only shorten the shelf life of cosmetics, but also may cause harm to users, resulting in allergic reactions and infections of consumers' skin. Because cosmetics contain moisture and nutrients that support the growth of microorganisms, they are more likely to be contaminated by pathogenic strains during use, and preservatives can protect cosmetics.Preservatives are antibacterial agents added to cosmetics to reduce the possibility of microbial contamination, which can inhibit the reproduction of microorganisms.
PET is used to evaluate the ability of cosmetics to resist microbial contamination after adding preservatives. PET is generally performed by first inoculating the sample with challenge microorganisms, and then observing changes in the number of microorganisms at different times to assess the efficacy of the preservative against contamination by these microorganisms. The cycle of PET is at least 28 days, and the formulation of products that fail to pass the PET evaluation needs to be optimized. Therefore, PET is a necessary test for cosmetic products before they are marketed, and it is very important for the determination of cosmetic safety.
Challenge Microorganisms:
- Pseudomonas aeruginosa
- Staphylococcus aureus
- Escherichia coli
- Aspergillus brasiliensis
- Candida albicans
In addition to the above five microorganisms, we also provide PET customized services for other specific microorganisms to meet the individual research needs of customers.
We provide testing services based on European Pharmacopeia, U.S. Pharmacopeia, International Organization for Standardization (ISO) and Personal Care Products Council (PCPC).
