Preservative Efficacy Testing Service
Overview
Preservative efficacy testing is a laboratory test that determines the level of antimicrobial activity of a product and assesses the ability of the product to resist microbial contamination during use. The cosmetic and personal care industries also use preservatives to prevent any harmful bacteria from contaminating their products. In this way, people can safely use these products on their skin.
Principle of Preservation Effectiveness Testing
The principle of the preservative efficacy test procedure is to inoculate the product with microorganisms and then evaluate the product at defined time intervals to see if the microbial population is reduced to the desired level within a given time period.
Workflow
Specific Services We Offer
- Microbiological challenge testing
Microbial challenge testing is an important tool for developing new product formulations or processes or validating control measures. Microbial challenge studies can be performed to determine if a product can support the growth of pathogenic organisms and to test the efficacy of natural preservatives, and our services include：
- Growth inhibition challenge studies can be conducted to assess the ability of a given cosmetic product to inhibit the growth of relevant pathogens or spoilage organisms under given storage conditions.
- Inactivation challenge studies can be used to determine if a given cosmetic formulation is capable of providing an appropriate level of target organism reduction.
- Verification of preservative efficacy
Considerations for Microbial Challenge Study Testing
When designing a microbial challenge study, a variety of factors must be considered, such as the intrinsic characteristics of the product formulation, storage conditions, target organisms, inoculum preparation methods, inoculation methods and levels, sampling considerations, and interpretation of test results. Because each of these considerations is specific to the product, process, and overall study objectives, it is important that studies be designed and evaluated by experts. Daji Belle has the extensive expertise needed to design and execute microbial challenge studies and to analyze and interpret the results.
- Preservative effectiveness testing
We conduct preservative effectiveness testing to assess the efficacy of preservative systems used in cosmetics. This testing determines the minimum concentration of preservative required to inhibit microbial growth. It also helps to optimize formulations to meet regulatory requirements.
