Stability and microbiological testing is required for all cosmetic products, whether classified as Grade 1 or Grade 2. During the safety assessment, the results of these tests are analyzed together with the ingredients present in the formulation, the manufacturing process and the purpose of application of the cosmetic product.

Tests required for safety assessment and definition of expiration date
Stability Tests:
The first step in determining validity is to perform stability testing. These tests evaluate product handling over time in different storage conditions, such as temperature, humidity and exposure to light. Through the analysis of physical-chemical, microbiological and sensory parameters, it is possible to identify changes in the composition, appearance or odor of the product, which indicate loss of quality or risk to consumer health. This data is used to prepare the product specification, which will be used to guarantee quality during the manufacturing process.
The ANVISA Guides for Quality Control and Stability of Cosmetic Products provide guidance on methods and processes to be used to achieve product stability and specification.

Microbiological Challenge Tests:
Microbiological contamination is one of the main risks associated with the use of expired cosmetic products. Microbiological challenge tests simulate product contamination by pathogenic microorganisms and evaluate the preservative's ability to inhibit their growth. These tests are essential to guarantee the microbiological safety of the product throughout its validity period.
Regulatory Bodies:
Validation of the validity of cosmetic products is regulated by several bodies around the world. In Brazil, the National Health Surveillance Agency (Anvisa) is responsible for establishing standards and procedures for evaluating the safety and quality of cosmetics. Compliance with Anvisa's requirements is essential to guarantee the sale of safe and practical products in the country.
Companies must stay up to date with best practices and regulations to ensure product safety and consumer trust.
