HELSINKI, Finland—The European Chemicals Agency (ECHA) has issued a call for evidence on a possible restriction proposal for 4,4'-methylenebis [2-chloroaniline] (MOCA).
The chemical is used principally as a curing agent for prepolymers for the manufacture of castable polyurethane rubber-based products.
Examples of these products include gears, gaskets, sport boots, roller skate wheels, shoe soles, wheels and pulleys for escalators and elevators as well as components in home appliances.
In a statement Oct. 5, ECHA said that MOCA is already on the REACH Authorization List and the agency has screened its uses and the risks in products.
"We are now looking for information to see whether a restriction proposal needs to be prepared to control the risks to people from this carcinogen that has no safe level of exposure," it added.
The deadline for comments is Nov. 16, 2022.
