1-tert-butoxy-.omega.-alkenes and their use as scents

2-tert-butyl-4-methylcyclohexanol is used as a scent and as a component of scent compositions. Scent compositions contain 2-tert-butyl-4-methylcyclohexanol (I), which influences their fragrance. It has a very intense earthy woody vetiver-like fragrance and is stable in neutral, acidic and alkaline solutions.
