Preservative challenge testing of cosmetics and personal care products is important to ensure the safety of the products prior to consumer use. According to the FDA, it is the responsibility of the finished product manufacturer to substantiate the safety of both ingredients and finished cosmetic products prior to marketing. The ability of a preservative system to protect the product from microbial growth and degredation must be established through microbial challenge testing of the complete formulation.
Challenge testing cosmetics is likely the single most important type of testing a cosmetic maker can do to protect their product. This testing allows manufacturers and formulators of cosmetics to have a clearer picture of how their products will withstand microbial attack which is inevitable during consumer use. Testing cosmetics and personal care products to ensure stability is necessary and cosmetic challenge tests are an essential part of any product's stability testing regimen.
