Morphology
The noun phrase is transparently built from the adjective 'saponaceous' (resembling soap) modifying 'substance' (matter), so the overall meaning 'a soap-like material' follows directly from the constituents. This simple adjective + noun composition is a standard, cross-linguistically common pattern, so a learner who knows both words would readily infer the MWE's meaning.
Etymology
Saponaceous substance comes from an old word for soap, so saponaceous means 'soap-like' and substance means 'material'. Picture a material that makes bubbles and cleans, so today the phrase means 'a soap-like material'.
