Viscosity is not considered to be a relevant physicochemical property for solid substances.

Key value for chemical safety assessment

Additional information

In accordance with section R.7.1.18.4 of ECHA's guidance on "Information requirements and chemical safety assessment" (R.7a, p. 184), viscosity (required in REACH Annex IX section 7.17) is relevant only to liquids. As L-leucine is a solid substance, determination of viscosity is not required.
