Can You Leave Hand Sanitizer In Your Car

According to the CDC hand sanitizer is most effective at killing germs when it contains at least 60% alcohol. But what happens if you leave hand sanitizer in your car on a hot day? The CDC doesn’t recommend leaving hand sanitizer in your car because it can reach high temperatures that can reduce its efficacy.

If hand sanitizer is exposed to high temperatures it can start to break down. This process is called “thermal degradation.” The active ingredient in hand sanitizer alcohol begins to evaporate when it’s exposed to heat. This can make the hand sanitizer less effective at killing germs.

In one study researchers found that hand sanitizers exposed to high temperatures were less effective at killing bacteria than those that were stored at cooler temperatures. The researchers exposed hand sanitizers to four different temperatures: room temperature 40°C (104°F) 50°C (122°F) and 60°C (140°F). They found that the hand sanitizers stored at the higher temperatures were less effective at killing bacteria.

The researchers also found that the higher the temperature the more the active ingredient (alcohol) evaporated. At 60°C (140°F) more than half of the alcohol had evaporated. This means that there was less alcohol available to kill bacteria.

The CDC recommends storing hand sanitizer in a cool dry place. This will help keep it effective for longer. If you leave hand sanitizer in your car on a hot day it’s still effective but it might not be as effective as it could be.
