Cologne doesn’t freeze near the typical freezing point of 32 degrees Fahrenheit (0 degrees Celsius, 273 degrees Kelvin). Most types of cologne come with a minimum alcohol content of 80%. Their high ethanol content prevents fragrances from freezing at these temperatures.
The higher the alcohol content, the lower the freezing temperature of perfume is. Pure alcohol only freezes at temperatures of -173 Fahrenheit (-114 Celsius). Of course, most perfumes are made from a lot of alcohol mixed with essential oils. This makes freezing colognes an uncommon sight.
An estimate of the freezing temperature of most colognes is -60 degrees Celsius (-76 degrees Fahrenheit).
Does cold ruin fragrances?
A related question is whether or not freezing cologne ruins the fragrance.
There is no scientific evidence that freezing colognes ruins their fragrance. In fact, some people swear by it. They claim that the cold keeps the scent fresh and prolongs its longevity.
However, there is also no scientific proof for this. There have been studies on how to preserve scents in extreme conditions. But they all focus on preserving the essential oils and other component, but these results aren’t applicable to colognes.
Wrapping it all up:
- Colognes don’t usually freeze because of their high alcohol content.
- Cold preserves the scent of colognes.
- There isn’t any scientific evidence that freezing cologne ruins the scent nor that it preserves scents.
