Cangooner I don't mind posting the recipe at all.
Its a bit labor intensive but the recipe will make you nearly 30 ounces of soap enough for 6-8 bars.This recipe costs me under 20 cents per weight ounce /under a dollar per bar cost but a soap maker will charge you 4 to 8 dollars per bar.
note of caution: be careful with the lye
Tools you will need:
A kitchen thermometer
digital scale
a hand blender
a crock pot
a heat proof container like a big pyrex measuring cup ( for the lye)
2 empty pringles cans
gloves and eye protection for working with the lye solution
These are ingredients for an all vegetable based soap where you can get all the ingredients at your local grocery store and the castor oil at a health food store.
For Ottawa folks:
I picked up the Castor Oil at the Natural Food pantry in Stittsville
and the rest at the grocery store (coconut oil is sold in the grocery store in the ethnic foods section)
the Lye i picked up at home hardware in Richmond
Recipe
Canola Oil 3 ( oz wt)
Castor Oil 2( oz wt)
Coconut Oil 4.5( oz wt)
Olive Oil 10( oz wt)
All Vegetable Shortening 8( oz wt)
Lye 3.7 ( oz wt)
10 fluid ounces of water
1.Weigh the oils and place in crock pot,
2.take a bowl fill with half and half water and vinegar and add some dish soap ( this is in case you splash any lye on your skin the soapy acidic water mix neutralizes the lye)
While wearing eye protection ( glasses or goggles) and neoprene gloves, go outside make sure you are up wind from the container and make sure you add the lye to the water not the water to the lye.
- pour the solid lye into the water, stir well. Set aside and allow to cool (100° F to 125° F). This is best done outside while you are standing upwind as the fumes coming off the lye are toxic and the lye reaches a temperature of nearly 160 degrees Fahrenheit
- Check the oils in the crock pot . Once the fats and oils are melted allow the temperature to drop to 100° F to 125° F.
- Combine lye solution and melted oils in the crock pot when the temperature of both falls under 125° F. The temperatures don't have to be exact just both the oil and the lye solution need to be under 125 degrees. Be careful not to splash while combining the mixtures (if you do rinse whatever body part got splashed with lye with the vinegar soap solution).
- Stir with a hand blender until the mixture traces.
- Tracing looks like a thick custard It will support a drop, or your stir marks for several seconds. Once tracing occurs...put a lid on the crock pot place it on high and take a break for an hour while the mix cooks (this to folks that make soap is called hot processing)
- With hot processing the soap can be used as soon as it hardens as the hot process cooks off all the lye in the mixture
- after an hour stir the mixture up , it will look almost translucent on the edges which is normal
At this point you can add scent if you want, recommended essential oils: lavender, sandalwood, orange oil, patchouli your choice
Also some shaving soaps call for clay as it assists the razor to glide over your skin. If you want to add clay to your mix let me know and i will post how to do so.
If you are adding scent add 2 teaspoons essential oil of your choice to the mixture (if your skin reacts play it safe and add half the amount of scent, you can always heat up the soap at any time til it melts and add more if the scent is too mild), stir again then scoop into your 2 pringles cans, tap the can as you are filling to remove air bubbles
leave the cans over night and the next day peel away the pringles can, slice your soap into bars, and use.
I hope thats enough information, any questions feel free to ask
