Comprehensive Testing for Precise Results

Our comprehensive stability Testing service rigorously tests your cosmetic products under a range of conditions, ensuring precise and reliable results. For this test, we test your product at 3 different temperatures for 3 months. Each temperature can test for a different year, 1, 2, and 3. The 3-year test will test your product at 50 degrees so it has a higher risk of immature failure however if your product fails at this temperature then we have the 45 and 40-degree tests to rely on so you walk away with either 1, 2, or 3-year shelf life equivalent.

Sample Requirements

Due to the extensive nature of the comprehensive stability testing service, we require 10 full-sized samples to test (100 grams each, if smaller please provide 20 samples or a minimum of 50ml equivelant).

Each temperature and interval check requires 50-100ml, so please plan accordingly when selecting our service. For more specific testing needs, consider our alternative options.

Our Service Guarantee

We provide a credit-back guarantee for 80% of the service cost if your cosmetic does not pass our initial tests. Along with the credit, we offer detailed feedback to inform your decision-making, whether for reformulation or applying the credit to another product.

Testing Duration

Our advanced testing simulates up to 3 years of product stability over a 3-month period. This efficient approach allows us to deliver reliable stability predictions for your cosmetic over 1, 2, or 3 years.
