Definition
ratio that is the mass of water contained in a material entity relative to a defined reference mass of that material entity
Explanatory Notes
1) The defined reference mass can be the total mass of the material entity, corresponding to moisture content on a wet basis, or the dry solids mass of the material entity, corresponding to moisture content on a dry basis. 2) Although moisture content is normally interpreted as the amount of water in a material entity, some analytical methods may report a value that includes other volatile material lost during drying or measurement. For this reason, moisture content is not axiomatically restricted here to water or water molecules. Method-specific interpretations should be captured through the measurement method, result interpretation, or a more specific subclass when needed.
Examples
- the moisture content of powdered cell culture medium on a wet basis; the moisture content of a lyophilized drug product cake on a dry basis; the moisture content of a resin lot after drying; the moisture content of a granulated medium before packaging; the moisture content of a dried excipient lot

Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
There are insufficient constructs to create a set of necessary and sufficient conditions
Formal Axioms
First-Order Logic Axioms
MoistureContent(x) → Ratio(x) ∧ ∃m (MaterialEntity(m) ∧ qualityOf(x, m))
Semi-Formal Natural Language Axioms
if x is a ‘moisture content’ then x is a ‘ratio’ that is the ‘quality of’ some ‘material entity’
