I was trying to figure out what is in class A firefighting foam last week. Nobody really wants to say, it is all trade secrets, evading a direct response, using vague sweeping terms, like it contains surfactant and foaming agents. However based on the published MSDS. my guess, soap, it is mainly soap. https://www.fs.usda.gov/rm/fire/wfcs/products/msds/foam/silvex-plus.pdf https://www.fs.usda.gov/rm/fire/wfcs/products/msds/foam/silv... Note that I do think it is soap finely engineered for it's fire suppression characteristics. I also think you would get 80% there with a bottle of dish soap.
