10 lbs by weight organic hemp oil
3.8 poiunds of water, some use distilled, but I use tap water
1.3 pounds of lye
Slowly mix the lye crystals into the water stirring continuously. Wear gloves, long sleeves, and googles in case of splashes or spills. I do this under the range hood vent fan because it produces fumes that are harmful. In the meantime, the 10 pounds of oil is warming on the element.
I do not pay much attention to temperature. This is a cooked soap, hot process and is ready to use when it is finished, however, it improves with age. The soap is soft, the consistency of petroleum jelly, and can be diluted with a variety of liquids to make liqued hand soap, shampoo, foaming hand soap, bathroom or kitchen cleaner (hemp oil is antifacterial naturally, though I don't know if the quality is retained thorugh the saponification and 3 hour processing. When the soap is done, I pack it in glass jars and seal it, then store it in a dark room. Light affects the soap, turning the lovely green of the fresh hemp oil a golden greenish yellow.
Slowly add the lye mixure to the warming hemp oil and stir slowly and carefully, still wearing the gloves and goggles.
At this point, I know the soap will take 2 or 3 hours to saponify, or longer. It has done so in 2 hours, even using a stick blender or yesterday, it took more than three. I finally gave up when it was thick but had not gelled to be translucent and wrapped it in towels and a wool blanket and went to bed after 1 am.
During the time the hemp oil and lye water is cooking (I use my gas stove on the lowest setting and put a lid on the pot but many doing smaller batches use crock pots and have good results for hot process), I do other things and check on the soap and stir it every 15-20 minutes. Nothing happens for a long long time. Be patient. The oil separates from some saponified materials which floats around like mushy rice granules in the oil. The colour changes from dark green to that golden greenish yellow, but don't panic, when it gels, it will go green again and stay that way if it is out of the light. I have kept the soap in a jar covered tightly for a year and it is somewhat thicker but still has the same properties. Once it was opened after a year, it was becoming more solid, so I actually made bars. I tried making bars from this recipe but they are way too soft and will take a year to harden in the open air, if at all. I do not recommend trying to make 100% hemp oil soap as a solid bar. Besides, in its gel form, it can be used for so many things.
Here are some things you can make:
Shampoo. 1 tablespoon to about 6 ounces of water, leave over night and stir gently in the morning. Add some patchouli or peppermint essential oils, just a few drops. Some scents do not work well with the intesne green meadow scent of the hemp oil and nothing disguises it, so it is best to embrace it and simply enhance it or go without. The shampoo will lather once, but not keep a lather. It leaves hair soft and shiny without the need to condition.
Shaving soap. Glop some into a container and leave it open to the air for a week. Then use it as shaving soap with a brush or alternatively, spread a tiny amount on your hands and rub it onto your parts being shaved, then add a little water until there is a smoothness and very gentle lather. Shave away.
Bathroom cleaner. Put some in a spray bottle with 1/4 c of white vinegar and water, maybe a drop of two of lemon essential oil or tea tree. Spray and clean naturally.
I have even washed a floor with it, but the floor was slightly slippery afterwards due to the excellent conditioning aspects of hemp oil. It is 90% conditioning as a soap, the highest single oil that is good for the skin, even better than rice bran or Argan oil. But, it is not cheap. Good things are worth the cost if you enjoy them and they are environmental and organic. There is a company in Britain that sells this soap for a lot of money and people seem to love it.
Hemp oil is grown right here on the prairies, in Alberta and next door in Saskatchewan and then Manitoba and it is processed in Manitoba. I buy the oil in a 5 gallon black food grade plastic bucket from the hemp cooperative company. The shelf life of the fresh 100% organic hemp oil is 6 months from opening, but it must be kept cool and dark or it will loose its potent vitamins and benefits. I will write about the benefits of hemp oil for the skin, hair and body in another post.
After I got tired of waiting for the soap to finish and turn translucent I wrapped it up in blankets and towels to keep the saponification reaction active, and went to bed, and sure enough it was perfect by this morning. I put it in various sized glass jars and it is in the basement where not much light comes in, but then I covered it anyhow. Pictures to follow.
Making the soap takes a lot of patience. I tried to get a friend to do it and though she did it three times, she did not cook it long enough or wait long enough and did not have what it was supposed to be. On the third try she persevered and was happy to report she had made the translusent jelly like soap! You can too. And it is sooooooooo amazing to use. Try it sometime!
