PURPOSE: To obtain a solid.liquid lubricant containing a specific modified silicone compound as a component, excellent in lubricating property, compatibility, retaining property, water repelling property, waterproofing property and stainproof property and useful as car wax, etc.

CONSTITUTION: The objective solid.liquid lubricant is obtained by reacting an organic silicon compound having one or more hydrogen groups with a ≥18C hydrocarbon compound having one or more double bonds capable of reacting with the hydrogen group. The lubricant contains e.g. a modified silicone compound obtained by adding ≥18C α-olefin to a polymethylhydrogensiloxane and/or a methylhydrogensiloxane-dimethylsiloxane copolymer as the component.
