The CTFA Safety Evaluation Guidelines provide manufacturers with guidance regarding the use of preclinical and clinical safety testing as a means to substantiate the safety of both ingredients and finished cosmetic products. They are part of the CTFA Technical Guidelines series.
Each Guideline undergoes an extensive development and review process by CTFA technical committees and staff, as well as public review by CTFA member companies, nonmember companies, federal government agencies, and scientific professional societies.
