This was a wonderful idea I was recently introduce to for soap for baby (in my opinion) for those mothers who breastfeed and maybe already make their own soap anyways. I wish I had heard of it when I was still breastfeeding. But I will definitly do this with #2
This recipe is from http://traditionalmidwife.com/mothersmilksoap.html
I am only copying and pasting the exact recipe here. The website has many more comments and discussion on it.
32 (4-ounce) bars
3 lbs. vegetable shortening
17 ounces dark olive oil
18 ounces Safflower oil
6 cups thawed breast milk
(you can use any amount of breast milk you like and substitute the rest,
just make sure your total fluid volume reaches 6 cups).
12 ounces pure sodium hydroxide (lye - Red Devil brand works)
1 ounce Borax
2 TLBS honey
1 ounce Essential oil - optional
Stainless steel pans
Wooden or stainless steel spoons
Newspaper to cover counter tops
***Wear Gloves and protective eye-wear when making soap...lye burns!!
****Use only stainless steel pans for making soap - DO NOT use aluminum!!
Melt the veg. shortening in a sauce pan (about 8 quart size)and add the oils. Bring temp up slowly until the shortening is all melted. Don't over heat or scorch the oils.
Plug your kitchen sink. Fill half way with water and add about 3 dozen ice cubes.
Put thawed cold breast milk in a sauce pan (about 3 quart size). Place the sauce pan into the water. You *must* keep the milk cool when you add the lye to it or the lye will burn it and make it unusable, not to mention real stinky!
Slowly stir in the sodium hydroxide (lye) stirring constantly and occasionally circulating the outer ice water. The lye is going to heat the milk up as you stir it in. Avoid breathing the fumes by working in a well ventilated area.
Adding the lye should take at least 5 minutes, any faster and you will burnout your milk. If you accidentally splash any on yourself, rinse immediately!
Once combined, continue to stir the milk/lye mixture for just a few more minutes (3) and then remove from the water bath and set aside. You will notice that the milk/lye mixture steadily becomes yellowish in color. That is normal.
Add the honey and borax to your melted oil which should still be warm but not hot (115 degrees or so).
Now, slowly and carefully pour the milk/lye mixture into the pan of oil. Stir constantly until it is all mixed together.
This mixture must now be whipped in a blender (2/3's full at a time for safety sake). Run the blender (with the lid on) at whip speed for 60 seconds each time. Pour off into a clean pan.
Repeat the blender process a second time. This is when you will add your essential oils.
Once the mixture has been blended twice, it will be ready to pour into a mold where it will saponify and be ready to cut after 24 hours.
**Make sure to set a few bars secretly aside for that someday when it could make a touching "Treasured Memory Gift" maybe when your child is all grown up. The soap will never go rancid (no matter what you may have read elsewhere), it will only improve with age. Mothering Soap has the unique potential of becoming something extra, special as the years roll by. But that's just this mothers thought!
