| Résumé : |
Wet wipes have become an increasingly popular item of everyday use in homes and in workplaces. Although originally developed as personal care products, their success has led to the development of many products with household and industrial applications such as cleaning, sanitising and polishing.
The preservation of wet wipes presents a number of challenges not encountered with other liquid products. This often requires a unique solution incorporating a combination of different preservatives to provide complete protection against microbial contamination.
The selection of an appropriate test method is critical to ensure confidence that a test result from the laboratory will truly represent what will happen in the field when the product is produced and released. Recently, Thor microbiological departments have developed a test method that produces consistent results. The methodology entails multiple inoculations with specific bacterial, yeast and mould species responsible for the spoilage of wet wipes and other consumer products. The intention of this article is to describe the scientific approach that has been followed to overcome all the critical points faced when generating a challenge test method for the preservation evaluation of wet wipes. |
