Hi Iori,
I assume the products that foam are based on either the chemicals used in them, (such as hydrogen peroxide) or due to the mechanical action of a detergent being forced through a sprayer.
I found some recipes on the web with detailed instructions for making your own soap. (bar & liquid hand soap, Laundry detergent and dish washing liquid). I have included the recipes below, detailed instructions are found on the respective web site.
Laundry Soap1 cup washing soda (I use Arm & Hammer)
1/2 cup borax (I use 20 Mule Team)
1 bar soap (I use whatever is cheap, in this case Pure & Natural)
Approximately 3 gallons water
