Morphology
unsaponified = saponified (semi-transparent) = un + sapon + ify + ed
The negative prefix 'un-' transparently negates 'saponified', but 'saponified' (and the combining form 'sapon-') is technical and not widely known to general learners.
Etymology
Unsaponified breaks into un- meaning 'not' and saponify, from Latin sapo meaning 'soap'. So unsaponified describes a fat or oil that was 'not made into soap' and so keeps its natural properties.
