Additional information

In accordance with section 2 of REACH annex XI, the viscosity study (required in section 7.17) cannot be conducted on solid materials. According to ECHA guidance chapter R7.a, viscosity is specific for liquid substances. Allantoin is a solid (powder) at room temperature and thus testing for viscosity is not applicable.
