Key Points

This study aims to assess the impact of alcohol-based disinfectants and cologne on breath alcohol concentration in different environments.
Conducted an experimental study with 35 healthy volunteers aged 18-65.
Applied 80% ethyl alcohol, 70% isopropyl alcohol disinfectants, and cologne.
Measured breath alcohol concentration using a calibrated device at specified intervals in both closed and open environments.
In closed environments, 90 seconds post-application, 88.6% of cologne samples exceeded legal limits.
In closed environments after three minutes, 51.4% of ethyl alcohol exceeded legal limits.
Averages for cologne application on skin were significantly higher than all other measurements.

Experimental study reveals alcohol-based liquids significantly affect breath alcohol levels in various environments, suggesting need for caution.
