Preservative Efficacy Testing (PET)

Preservative Efficacy Testing (PET) takes place after you have received and approved the formulation samples developed by our chemists. Preservative Efficacy Testing is designed to assess whether the chosen preservatives in the formulation provide sufficient protection against contamination.

Preservative Efficacy Testing simulates microbial contamination and is conducted in a controlled laboratory environment by a certified third-party microbiological facility.

Once the product passes PET, our chemists will provide you the results and answer any questions you may have.

Stability Testing

When it comes to cosmetics, we believe that the longevity and consistency of a product is crucial to success. Without a sufficient shelf life, your products will not last in the hands of your customers by the time they have made it through manufacturing, shipping, storage and dispatch. Additionally, regulations in many overseas markets require a proven minimum shelf life in order for a product to be sold. 

So, how do you know what your product’s shelf life is? The only true indicator is time – but with the pressures of running a brand and the need to take products to market, it isn’t exactly practical to leave your products on a shelf and come back in a few years to see how they’ve held up. The only solution is to put your products through accelerated stability testing.

Stability testing involves subjecting product samples to a range of temperatures over a 12-week period and is designed to simulate the various conditions a product will experience over its lifespan. Throughout the 12 weeks, the product is continuously assessed for changes in colour, viscosity, Ph levels, smell and how the product interacts with the packaging. Once the product passes stability testing, our chemists will provide you the results and answer any questions you may have.

Micro Testing

The final stage of testing that products undergo is micro testing, which takes place as part of the manufacturing process. Once your product has been compounded by our team, a sample is sent to an independent laboratory to check for any microbial contamination. After your product has been filled and packaged, we send another sample to the laboratory to ensure that no contamination has occurred during manufacturing.

Once we receive the final results from the laboratory, your product is finally ready to be dispatched from our manufacturing facility.
