I wanted to try out making my own foaming hand soap to see if I would save money. I also wanted to replace using plastic in favor of easily recyclable glass. And eventually, I decided to make it in a scent that I love.
Here is the recipe in case you don't want to read my jibber jabber.
FOAMING SOAP RECIPE
3 parts water
1 part of your favorite liquid soap or body wash (NOT foaming soap)
Directions: Fill measuring cup to line with water, then add soap (putting soap first then water will make it foam), stir until mixed, pour in foam dispenser.
MATH SKILLS... if you're confused about 3 parts to 1 part, also called a 3:1 (three to one) ratio, here is an explanation. Take the total of how many ounces or mL you want to make and divide by four. That number is your 1 part. Take that number and multiply by three, and you get the three parts. It's like taking a pizza divided into four slices, three getting pepperoni (3 parts) and one getting sausage (1 part). Another way to do it is 75% water and 25% soap.
