Follow the instructions in that thread except for dissolving the potassium hydroxide in glycerin, because that is a foolishly dangerous approach. Just dissolve it in water (50/50 by weight) and combine it with the glycerin for the same results.I am just starting soap making. Does someone have a simple liquid soap recipe?
Any help is greatly appreciated!
I've personally never had a problem dissolving the KOH in glycerin either- it's always gone well for me.I have never had a problem with using all glycerin to dissolve the potassium hydroxide.
It's more difficult and (depending on exactly how you do it) either more dangerous or way more dangerous than dissolving the KOH in water.I have never had a problem with using all glycerin to dissolve the potassium hydroxide.
Somehow I failed to see your response before I posted mine. You provided the details of what I referred to as "way dangerous" versus simply "dangerous".If doing it the (correct) Pharmacist's way makes you nervous, TOMH is absolutely right that one can still make liquid soap via the glycerin method without having to dissolve the KOH in glycerin.....
This was super helpful, thanks Susie!Shelbyw-welcome to the forum. Please ignore the hijack of your thread. I assure you that this is not the normal behavior of our esteemed soapmakers.
I make cold processed liquid soap. Which is as simple as it can get as I abhor extra steps. Here is an abbreviated version of my current process for hand soap, it is actually IrishLass' recipe with a very minor change, to get the full version you can read the thread linked above. Be very sure to weigh everything carefully, and always use gloves and goggles. This has a 3% superfat.
Coconut Oil 25% 8 oz
Olive Oil 65% 20.8 oz
Castor Oil 10% 3.2 oz
KOH 7.1 oz (set calculator to 90% purity)
Water 10 oz
Sugar 1 tablespoon
Glycerin 11.3 oz
Melt and mix the oils. Add the glycerin to the oils.
Mix the KOH in small increments, stirring vigorously with the water.
Once the KOH is completely dissolved, add it to the oils.
Stickblend until you get an applesauce, you will then think it is ready, it is not. Continue to stickblend, it will go back to liquid, but once it is liquid, be prepared for either flying bubbles or almost instantaneous paste. I have had it do both on the various batches I have made. Either way, you are done stickblending. Cover the pot and walk away. I usually clean up all my soaping stuff and wash the dishes. Once you have taken a break for half an hour or more, start checking the paste. Once you see it looking like vaseline was mixed in, you can zap check it. If it is zapless, you can begin dilution. My theory is that the hotter your oils and your KOH/water mixture, the less time it takes to hit gel stage, but I have no proof. I have had this take as little as 20 minutes, and as long as 4 hours.
I then add Sodium lactate 1.2 oz, but this is purely optional.
I dilute with 46 oz water. It will need some stickblending at the end to mix in the final lumps of paste, but it will be a lovely thick liquid soap.
TOMH-please start a separate thread with a discussion on your concerns regarding the safety of the glycerin/KOH mixing procedures. This is not the place.
I've been thinking a lot about this since my response yesterday, and of course, what you say above makes absolute logical sense.Somehow I failed to see your response before I posted mine. You provided the details of what I referred to as "way dangerous" versus simply "dangerous".
I agree with your right way of dissolving KOH in glycerin if that is necessary for any purpose. Thing is, I don't really think this has anything to do with whether the procedure makes someone nervous. It's about whether there is any reason at all to do it. If there was a result you could only get by dissolving the KOH in glycerin, maybe there would be an argument for it. But if you can get the same result by dissolving KOH in water and mixing it with room temp glycerin, that is flat out the only procedure we should be discussing.........
A name like the "pharmaceutical method" gives it credibility as a thing. To tell the truth, at the moment I have doubts that it's an actual thing. In the vast expanse of the Internet, there appear to be no references to it.
That all makes good sense. I figured you and at least some others would continue doing it the way you're used to. I think maybe new people shouldn't be encouraged in that direction, which might be the main thing to consider. And perhaps being careful to express the dangers realistically. When this seemed like the only way, maybe the risks got slightly underplayed. In reality, dissolving KOH in glycerin really stands out for its riskiness compared to other soaping procedures.I've been thinking a lot about this since my response yesterday, and of course, what you say above makes absolute logical sense.
The Pharmacist's method- for what it's worth, probably better known as the "USP XIII glycerin method" because it originates from the USP (United States Pharmacopeia) XIII manual- was how I was taught from the very beginning of my liquid soap-making endeavors.
A little back history: My 'teacher' of the method if you will, was/is a retired medical doctor who had been using the method for many years to make his own glycerin liquid soap at home (Silverdoctor over on the Dish forum). He happened to be the source that inadvertently started the whole glycerin liquid soap-making craze back around 2010 amongst the community over at the Dish.
Anyway, he actually was not a member of the Dish at that time, but there was another member of the Dish (Tarafotty) that had seen the USP recipe that he had posted on About.com and began using it herself with very good results and she told someone else about it..... and then it pretty much took on a life of its own over at the Dish from there.
Silverdoctor eventually joined the Dish when much talk began to be generated over it (in that very looooooong glycerin method thread over at the Dish), and the rest, they say, is history.
Anyway, you know what they say about old habits dying hard- I had suckled at the breast of the USP/Pharmacist's method from the very get-go of my GLS endeavors, and since I was taught the correct way by an excellent teacher and had never experienced a single problem during my execution of it, I never looked into there being an alternative/better/safer way of doing it..... so, for better or for worse, that's my excuse for my continued postings about the method.....
And also for better or for worse, the fact that many GLS soap-makers old and new continue to dissolve their KOH in glycerin because of the instructions on a myriad of blogs and videos out there, I will continue to post about it, if for no other reason to make sure that those that attempt to do it that way, will do so correctly.......but I will no longer post about it without also posting the alternative/better/safer way.
Everyone has their way of doing things.Hi All,
Informative posts! Thank you! I've been making my soaps by the Failor methods for like ever since her book came out. That is the only method I'm well versed in. I've got it down to a science by now! LOL. I keep hearing about this glycerine method. I admit I've never tried it. I have read Thompson's book, and her method of the no paste way. I admit I'm set in my ways. Is it really easier and quicker with the glycerine, no paste method? After reading the posts, it just seems like A LOT of work to me. Depending on the oils I use, I get to a paste in less than 30 minutes most days. I rarely if ever add glycerine to my soaps, maybe as an additive for clarifying and extra emolliment. I don't necessarily have to cook my paste for 4 hours either. Each oil and batch have their own characertistics and at times I have a batch done in less than two hours. I make wonderful thick gels, using primarily soft oils and some borax. Am I missing something? If the glycerine method is really quicker and easier, please fill me in!
