One of the goals of the European REACH regulation is the progressive replacement of substances of very high concern (e.g. carcinogens) by safer alternatives. Companies that use these substances, actively search for safer alternatives (less dangerous substances, new technologies and processes), and report about these alternatives. Below you will find the information on possible alternatives for chromium trioxide, included in the different applications for authorisation received so far by ECHA.
