How do I add Specific Concentration Limits (SCL’s ) to raw materials for eye damage/irritation?
CLP does not have all these end points, and has instead:
Category 2/2A in GHS is aligned with Category 2 in CLP
*Assign SCL’s for Eye damage / irritation*
Using the example of Acetic Acid CAS 64-19-7, this has SCLs as follows:
C ? 90%Skin Corr. 1A; H314 / 25% ? C < 90% Skin Corr. 1B; H314 / 10% ? C < 25%Skin Irrit. 2; H315 / 10% ? C <25% Eye Irrit. 2; H319
SCL for Eye Irritation Category 2 is entered onto Formpak in the CLP Hazards property group on the property: EDI 2= (note EDI 2= and not EDI 2) as follows:
However, because there are related hazards that are not assigned a Specific Concentration Limit, values must be added for these otherwise the more severe hazards will be triggered at a dosage lower than the Specific Concentration Limit for the lesser hazards, when the General Concentration Limit applies, which is not the intention.
