Under EU Regulation 1223/2009, cosmetic and personal care products must prove that their preservative systems are effective throughout the product’s lifecycle. The best way to demonstrate this is through Preservative Efficacy Testing (PET) — also known as the Cosmetic Challenge Test.
At QACS, The Challenge Test Lab, we specialize in PET to help you confirm that your product is safe, stable, and compliant. Our ISO-17025 accredited lab performs challenge testing using standardized, industry, or custom-developed protocols, aligned with international guidelines.
