fragrance. (0.1% or less, usually lemon)
The silicone oil and the wax in the wax emulsion provide the anti-dusting properties. Hydrocarbons are not as prone to static electricity and therefore do not attract dust like other cleaners. The wax is also there to provide a hard base so that the film is more permanent. The silicone oil makes the surface slick and smooth. The mineral spirits act as a solvent that is safe on wood and allows the coating to level (become smooth). The water is to make it cheaper and the fragrance makes it stink.
