Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

No repeated dose studies for the derivation of DNELs are available or planned due to exposure considerations:
According to REACH Annex XI section 3.2 (b) and (c), testing is omitted, based on the scenarios developed in the CSR. In scenarios describing the substance not being incorporated in an article it could be demonstrated that strictly controlled conditions as set out in Article 18.4. (a)-(f) apply throughout the life-cycle of the substance. Furthermore it was demonstrated that the substance is not released from articles based on the use of the substance as a monomer and that exposure to workers, to the general public and to the environment is negligible under normal or reasonable foreseeable conditions.
Local effects:
According to ECHA Guidance on information requirements and chemical safety assessment Part E: Risk characterisation, disulphur dichloride (S2Cl2) should be allocated to the high hazard band due to classification as a corrosive compound; R35.
Potential systemic effects are unlikely:
S2Cl2 is rapidly (t 1/2 < 2 minutes) and quantitatively (97.7 - 101.7 %) hydrolysed in water at 23 °C and pH ranging from 4 to 9 in a guideline hydrolysis study. The hydrolysis products are HCl and different sulphur containing molecules in varying amounts including sulphite, sulphate, thiosulphate, sulphide and precipitable sulphur.
Based on the toxicokenetic considerations in IUCLID chapter 7.1 systemic toxicity of the hydrolysis products is low, as the hydrolysis products are endogenously occurring substances. Due to the corrosive nature of S2Cl2 no significant exposure is assumed (high hazard band); and it can be assumed that that no hydrolysis product is present at biologically relevant doses after exposure to S2Cl2. At concentrations not exceeding the buffer capacity of body fluids, the free acids resulting from the hydrolysis of S2Cl2 will be neutralized quickly by body fluids and do not pose a systemic risk to human health.
