Challenges emerge when ingredients are used in both cosmetics and other applications that fall under industrial chemical legislation, which often mandates animal testing. Despite efforts in various regions to reduce animal testing in chemical regulations—such as the EU’s REACH initiative or the United States’ Toxic Substances Control Act—specific requirements for animal-derived data persist. This is also true for pesticide regulations globally. To advance the adoption of non-animal testing methods, greater investment is required to enhance regulatory acceptance of flexible and integrated approaches. These methods combine various data sources to meet legislative requirements.
**”To facilitate the use of non-animal methods, more effort is needed to improve the regulatory acceptance of flexible, integrated approaches.”**
Building on widespread public and European Parliament support, the European Commission (EC) has pledged to create a roadmap aimed at phasing out animal testing in the chemical industry. Similar initiatives have been developed in the U.S. and are underway in Canada, striving toward a future where chemical safety assessments rely minimally, if at all, on animal testing.
Building Confidence in Innovative Approaches Through Education
The European Parliament has highlighted the importance of “sustained training and education” to accelerate the transition to animal-free scientific methods. In October 2024, the European Commission held its second workshop on the roadmap to eliminate animal testing in chemical safety evaluations. Jay Ingram, Chemicals Director at Humane Society International, remarked, “A key indicator of the roadmap's success will be a paradigm shift in regulatory safety assessment. Reducing knowledge barriers and building confidence in Non-Animal Methods and Next Generation Risk Assessment is critical for ensuring that all stakeholders possess the tools and vocabulary necessary for this shift.”

Introducing the AFSA Master Class for Animal-Free Safety Assessment
To support global educational efforts, the Animal-Free Safety Assessment Collaboration (AFSA) has assembled a team of toxicology experts to deliver a free online training course. This program, known as the AFSA Master Class, focuses on evaluating the safety of cosmetic products and ingredients without relying on new animal testing. The course provides a comprehensive overview of safety assessment processes, covering topics such as:
– Consumer exposure evaluation
– Predictive chemistry
– Exposure-based waiving techniques
– Dosimetry and internal exposure estimation
– In vitro (non-animal) testing methods
– Integrated case studies addressing issues like genotoxicity, phototoxicity, skin and eye irritation, dermal sensitization, and systemic long-term effects
This training program is tailored to empower scientists everywhere with the knowledge and skills to adopt animal-free safety assessment practices for cosmetics and other ingredients on a global scale.
A Paradigm Shift in Safety Assessment
The course highlights that safety assessments based on non-animal methods are conceptually similar to traditional approaches but differ in key aspects. For instance, animal-free methods emphasize exposure estimation from the outset and throughout the entire evaluation process. Additionally, bioactivity predictions rely on combining non-animal and predictive data, which are structured to address specific regulatory concerns, rather than adhering to a predetermined list of tests for each chemical.
By fostering education, innovation, and confidence in non-animal testing methods, initiatives like the AFSA Master Class are paving the way for a future where safety assessments depend less on animal testing and more on cutting-edge, humane approaches.
