Antiseptic efficacy testing aims to determine the effectiveness of antimicrobial agents present in cosmetics. These tests evaluate the ability of cosmetics to kill or inhibit the growth of microorganisms. The most common test is the preservative efficacy test (PET). PET evaluates the effectiveness of preservatives in preventing the growth of microorganisms in cosmetics.
Cosmetic preservative efficacy challenge testing, also known as antimicrobial effectiveness testing, is a microbiological test that evaluates the ability of a product's preservative system to prevent bacterial, fungal, and yeast growth. The test measures the effectiveness of the preservative system under "challenge" conditions, which simulate the conditions that may occur during normal product use.
There are several factors that can affect the efficacy of a preservative system, including the type of microorganisms present, the product formulation, the storage conditions, and the packaging materials. Alfa Chemistry's preservative efficacy challenge testing can provide valuable insights into the performance of the product's preservative system under varying conditions.
