Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Substance irritation/corrotion is driven by the characteristics of the individual UVCB constituents.
Relevant information on the individual UVCB constituents is reported in Section 7 Summary.
Key value for chemical safety assessment
Additional information
Justification for classification or non-classification
Skin corrosion / irritation: Skin Corr. 1A H314: Causes severe skin burns and eye damage
Serious damage / eye irritation: Eye Damage 1 H318: Causes serious eye damage
The estimated hazard is representative for the substance across industry, as defined by the maximum of the typical elemental concentration across industry (as outlined under IUCLID section 1.2).
The UVCB is a complex metal containing substance, which major constituents are sulphuric acic and water, as well as nickel, copper, zinc and arsenic (soluble) sulphate salts. Sulphuric acid is a mineral acid that has high affinity to water. It dissociates in water to form sulphate and hydrogen (carbonium) ions. These, as well as CuSO4 and NiSO4, as well Arsenic and zinc sulphate salts are the relevant forms to determine hazard properties of the substance. The constituent triggerring irritation to eye and skin is sulphuric acid (typical above 20%)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
