Vegan Challenge/PET Test

PET or challenge, tests the efficacy of the preservative in your product.

It involves challenging the product with a range of organisms to measure how quickly it clears them.  This simulates the experience the product will have when launched onto the market.

This test is the gold standard for checking whether your product's preservative is up to the job, and now we offer a vegan option of the test.

The testing takes around six weeks to complete, and we supply a report that explains in plain language what the results indicate.
