Chromium trioxide has various toxicological properties, such as acute and chronic toxicity, corrosivity as well as skin and respiratory sensitisation. It is also a reproductive toxicant, a germ cell toxicant and in particular, a carcinogenic substance. Chromium trioxide is mainly used in metal finishing/surface treatment and as catalysts.
Chromium trioxide, Chromium(VI) oxide . Registration dossier . Chromium(VI) trioxide . ECHA has launched a consultation on 6 applications for authorisation covering chromium trioxide (EC 215-607-8; CAS: 1333-82-0) used in etching as a pre-treatment step in the electroplating processes of plastic substrates; in functional chrome plating of different types of substrates (including functional chrome plating for decorative purposes); used as colouring and hardening agent for Chromium Trioxide (CrO 3) Chromium trioxide is a strong oxidizing agent that is not soluble in most organic solvents and tends to explode in the presence of organic compounds and solvents. In water, it forms chromic acid and anhydrides, from which salts such as sodium dichromate (Na 2 Cr 2 O 7) and pyridinium dichromate are commercially available.

3. for Uses 3 (functional plating with decorative character), 5 (miscellaneous surface treatment) and 6 (passivation of tin- plated steel (ETP)), and until September 21, 2024 for Uses 1 … Chromium trioxide is soluble in tert-butyl alcohol, pyridine (see Sarett Reagent, Collins Reagent) and acetic anhydride, although care must be taken to follow the given procedures, because these solutions tend to explode. A solution of chromium trioxide in aqueous sulfuric acid can be safely mixed with acetone (Jones Reagent).
The European Commission has granted authorisations for chromium trioxide, stating that it has imposed strict conditions for the companies involved. Chromium trioxide, containing Chromium VI, is used for electroplating of packaging, household furniture, electricals and fittings, jewellery, car and aerospace parts, among other items. The decision will oblige companies that have applied to use chromium trioxide, a substance of very high concern due to its carcinogenic properties, to implement strict risk management procedures for various uses of the substance in the automotive, aerospace and other sectors. A major use of chromium trioxide has been in chromium plating, particularly in the production of automobiles.
