How can I aerosolise hydrogen peroxide solution?
« on: 13/07/2013 16:30:07 »
Daniel  asked the Naked Scientists:
   
I would like to create an aerosol can which will diffuse a tiny droplet's of fog and will be diffused through a gas pressure fogger style tin can.

If I fill the can with water mixed with Hydrogen Peroxide most of the liquid will remain the tin.

Is there a way to take Hydrogen peroxide mix with other gas to create  the pressure which will diffuse the gas evenly across the room area/volume.

If so which formula will you suggest using remember it must not be hazardous, nor flammable or explosive.  Content of hydrogen peroxide around 5-7% .

As water mixed with HP will come out more like a spray, I need to find a solution which will come out more like a very fine mist.

Regards.
Daniel

What do you think?

Such an aerosol could easily be inhaled or get into eyes ...

HYDROGEN PEROXIDE ... Human Health Effects:

 Inhalation and ocular
          exposure of household strength hydrogen peroxide (3%) can cause respiratory irritation and mild ocular irritation, respectively.

Hydrogen peroxide vapor is a primary irritant, primarily affecting the eyes and respiratory system and the NIOSH Immediately dangerous to life and health limit (IDLH) is only 75 ppm. Long term exposure to low ppm concentrations is also hazardous and can result in permanent lung damage and Occupational Safety and Health Administration (OSHA) has established a permissible exposure limit of 1.0 ppm calculated as an eight hour time weighted average (29 CFR 1910.1000, Table Z-1) and hydrogen peroxide has also been classified by the American Conference of Governmental Industrial Hygienists (ACGIH) as a "known animal carcinogen, with unknown relevance on humans

Ultrasonic water misters are available ...

The mist will hug the ground (and it could bleach the colour from your carpet if it has hydrogen peroxide added).
