I don't know about shampoo or body soap but I recently made my own
I have been making my own laundry soap for about 7 years now.
I haven't made soap since we studied Colonial America in 4th Grade, but I used to have some 95% traveling co-workers who made their own liquid soap (like for showering or next to the sink).
I found this recipe for laundry detergent, but haven't gotten around to trying it.
I did tons of research before making it the first time, this site seemed to be the best
here is her recipe w/ my notes
all ing are at freddys in the laundry isle think top and bottom of shelf... this isnt the stuff they are making money on thus isnt eye level (!!)
Homemade Laundry Soap
1/3 bar Fels Naptha or other type of soap, -- I used the fels naptha
½ cup washing soda --yellow box
½ cup borax powder -- greenish box
~You will also need a small bucket, about 2 gallon size~
Grate the soap (I use my food processor) and put it in a sauce pan. Add 6 cups water and heat it until the soap melts. Add the washing soda and the borax and stir until it is dissolved. Remove from heat. Pour 4 cups hot water into the bucket. Now add your soap mixture and stir. Now add 1 gallon plus 6 cups of water and stir. Let the soap sit for about 24 hours and it will gel. You use ½ cup per load.
I keep big bucket in the master bathroom- need to stir each time you pour into pitcher. shake pitcher each use. use abt 1/2 cu
I also add a bit of oxygenated bleach (safe for colors and environment) to really dirty loads and it does an awesome job getting stains out.
