Can react violently upon contact with reducing reagents, including organic matter, leading to ignition or explosion. Dangerously reactive with acetone, alcohols, alkali metals (sodium, potassium), ammonia, arsenic, dimethylformamide, hydrogen sulfide, phosphorus, peroxyformic acid, pyridine, B. whereas chromium trioxide was included in Annex XIV to the REACH Regulation in 2013 (6) due to that classification, the high volumes currently in use, the high number of sites where it is used in the Union and the risk of significant exposure to workers (7), with a sunset date of 21 September 2017; 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 To Downstream Users who use Chromium trioxide for Use 3 ‘Functional Plating with Decorative Character’ If you are using Chromium trioxide as a substance or in a mixture for functional plating with decorative character including pretreatments (such as etching) (‘Use 3’), please read this Information Notice carefully. 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.

It has been used widely and works fine in selectively dissolving the AAO layer while leaving the aluminium foil intact. 2011-05-09 Hexavalent chromium trioxide and sulphuric acid are typically used in the electrolyte during the plating process. As a result, while the resultant coating is non-toxic, the electrolyte and waste products of the process are highly toxic, posing a health risk to workers and the local environment. Chromium 6: Is used in pigments for textile dyes, paints, and inks; Is used in chrome plating processes, and in wood preservatives.

Chromium trioxide, Chromium(VI) oxide . Registration dossier . Chromium(VI) trioxide . Hexavalent chromium compounds (including chromium trioxide, chromic acids, chromates, chlorochromates) are toxic and carcinogenic. For this reason, chromic acid oxidation is not used on an industrial scale except in the aerospace industry. 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 Chromic acid; Chromium (VI) oxide; Chromium 01333-82-0 100 anhydride 9.
