In the case of fluctuating PET results for w/o products, it can be useful to increase the number of samples to verify the results.
Determining Preservative Efficacy in W/O Formulas, Part II: Making Microbiological Safety Assessments
The relevance of microbiological tests for w/o formulas has been questioned, mandating a more holistic approach. This second article in a series examines the failure rate of PETs for w/o products but looks at why this does not mean insufficient stability.

Microbiological test methods for w/o formulas have raised questions in terms of their suitability. They also require a more critical view of the results than other product types. This first article in a two-part series reviews the limitations of such methods and options for their optimization. It also critically observes to what extent test results provide relevant information for an appropriate safety assessment. Part II, in August 2022, will explore a holistic approach to more accurately assess microbiological safety.
Determining Preservative Efficacy in W/O Formulas, Part I: Test Performance and Limitations
To test such products under real-use conditions, an exaggerated cumulative clinical is proposed and demonstrated here in a study assessing the mildness of a care cleansing formula. In today's reality, cleansing products must be developed to overcome the potential adverse effects caused by frequent and repeated use.
