Morphology
The phrase is compositionally built: 'lubricating' (causing lubrication or reducing friction) modifies 'substance' (material), so the meaning 'a material that reduces friction' is directly derivable from the parts. The participle+noun pattern is a regular, cross-linguistic construction, so a B1 learner who knows both constituents should understand it.
Etymology
Lubricating substance brings to mind putting oil between two metal parts so they slide past each other without rough rubbing. So, a lubricating substance is any material that makes surfaces 'smooth' and stops them from rubbing, helping machines work well.
