Chromium VI compounds are highly toxic for both acute and chronic exposures and can cause cancer. Chromium is mainly used to produce alloys. Chromium compounds, in either the chromium (III) or chromium (VI) forms, are often used for chrome plating, the production of dyes and pigments, leather and wood preservation, and treatment of cooling tower water.
Chromium VI compounds are included in REACH Annex XVII restricted substances list (entry 47). The restriction conditions are listed as follows
|Cement and cement-containing mixtures||<=2 mg/kg (0,0002%) soluble chromium VI|
Leather articles coming into contact with the skin and articles containing leather parts coming into contact with the skin
<3 mg/kg chromium VI in leather or leather part.

Cr (VI) compounds are also restricted by the following 2 regulations:
