Açıklama

The Preservative Efficacy Test, also known as the Challenge Test, is an essential part of cosmetic product safety assessment under EU Cosmetic Regulation (EC) No 1223/2009. It evaluates whether the preservatives in your product effectively prevent microbial growth during its shelf life, ensuring consumer safety and regulatory compliance.

Including challenge test results in the Product Information File (PIF) demonstrates that your product is microbiologically stable and safe for use, which is a key requirement for EU market access. Tests are conducted according to ISO 11930:2019 and other relevant international standards, covering bacteria, yeasts, and molds.

We work with fully accredited laboratories, providing reliable, EU-compliant results. Samples are shipped directly to the labs, and our team guides you on proper sample preparation and shipping to ensure accurate testing.

Are any products exHow can I tell if my product is exempt from the challenge test?empt from the challenge test?	Some cosmetic products may not require a preservative efficacy (challenge) test, depending on their formulation and microbial risk. Common exemptions include: Completely anhydrous products (contain no water) or those with very low water activity. Single-use or contamination-proof packaging, such as sealed ampoules or sachets. Alcohol-based products with sufficiently high antimicrobial content. Even if your product may qualify for an exemption, microbiological testing is still recommended to confirm its initial microbial quality and support your Product Information File (PIF). Any exemptions and the rationale should be documented in the CPSR, in accordance with Annex I, Part B of Regulation (EC) No 1223/2009.
