Just asking a quick question for my science fair project. I was wondering what the other ingredients in disinfectant sprays do. Ex.(dimethyl benzyl ammonium chloride, water, propane, isobutane, sodium nitrate, sodium benzoate, and soyethyl morpholinium ethosulfate. If you could just send a rundown of each of the ingredients, that would be amazing. Thank you. Sincerely,

Answer 1:

Most of those chemicals are poisonous, so they kill the bacteria or protozoans that they come into contact with. I don't know how all of them work, but I can tell you that propane and isobutane are nonpolar solvents so will dissolve oils and other similar things, while water is a polar solvent that will dissolve salts and such. Sodium nitrate is a salt, so is probably poisonous because it sucks water out of the cells that it hits.

Answer 2:

Some of the ingredients in the disinfectant spray will be for making a nice fine mist. Other ingredients will be just for diluting the active ingredient in the disinfectant to the right concentration, so that you're not spraying too much disinfectant with every spray.

You can google the chemical names to get an idea of what they do.
