Product Challenge Testing

If your products are not properly preserved, dangerous bacteria, molds and fungi can colonize and invade the body through the skin and cause serious health problems. If you create products for sale to the public, properly preserving them is mandatory. Simply adding a preservative to your products is not really enough because you cannot tell with certainty if your chosen preservative is working effectively within your particular formulation. Even the most time-tested preservatives can fail to work if inadequate amounts were used or if they were broken down by heat, pH or other factors during the creation of your products. It is essential to ensure that your preservative is working and will continue to work over a long period of time. This is generally confirmed by having your product tested by a lab. The lab will challenge test your product and will let you know if it has remained microbe-free after being repeatedly introduced to the most commonly found microbes.

The laboratories listed below have indicated that they perform challenge testing for cosmetic and toiletry products. This list is provided as a convenience to From Nature With Love's customers. Before choosing to use any lab for your testing, please confirm their qualifications and the exact testing that they will perform.
