Why do oils make surfaces shiny? Will saponified oil behave the same way?

Most of the oils make solid surfaces shine when applied in thin layers. Whether same property will be retained in a saponified oil solution?

The shininess imparted by oil to a solid surface has to do with the fact that it creates a layer whose surface self-polishes through surface tension, and also alters the index of refraction at the surface of the solid in such a way as to reduce reflections there. Saponified oils -- I would imagine they would not work as well, at least not unless mixed with water -- by reason of their lesser fluidity.
