 According to the industry advocacy group the American Council on Science and Health, though the cosmetic industry is predominantly responsible in ensuring the safety of its products, the FDA also has the power to intervene when necessary to protect the public but in general does not require pre-market approval or testing.The ACSH says that companies are required to place a warning note on their products if they have not been tested and that experts in cosmetic ingredient reviews also play a role in monitoring safety through influence on the use of ingredients, but also lack legal authority.According to the ACSH, overall the organization has reviewed about 1,200 ingredients and has suggested that several hundred be restricted, but there is no standard or systemic method for reviewing chemicals for safety and a clear definition of what is meant by 'safety' so that all chemicals are tested on the same basis.
