Step 9: A Big Ol' Pot of Soap

Ready to be bottled and given to your friends and family.

I hope this has been helpful. It was done kind of in a hurry, so if there's any ambiguity, I apologize. Contact me with any questions.

Very clover, conversational and involving type of instructables.
<p>Thanks so much for this instructable. It's exactly what I needed. Also is the picture of the soap in step 7 hard or is it supposed to be soft? My tends to be soft so I keep cooking t thinking it's not done and it keeps bubbling. Also please help me figure this out, I've attached a picture. I used 60% olive pomace, 30% coconut 76 deg and 10% unrefined sheabutter and 5% supperfat. Is this layer my superfat or unsaponifiables. My Litmus paper turned green between 8-9 but the phenolp... remained clear</p>
thanks! I've been making cold process bar soaps for a while and now I'm looking into making liquid soaps as well.
Thanks for sharing, very informative...
great instructable, can't wait to try it.
Very cool soapmaking tutorial.........what you said is true there is sooo much info on the web for bar soaps but almost nothing on liquid soap Thank you very much
I know this is an old thread, but please know that recipes cannot be copyrighted. The description of HOW to make a recipe can be, but the basic ingredients cannot. As a courtesy, I would credit the source, but don't worry about copyright...you're just sharing a list of ingredients and measurements, nothing that is protected by copyright law...it's even questionable that the process to make soap could ever be protected (processes would have be a patent protection, not copyright, by the way) So share away in the future, and just be nice by saying where you found the information originally! from http://www.washingtonpost.com/wp-dyn/content/article/2006/01/03/AR2006010300316.html &quot;Copyright law specifies that &quot;substantial literary expression in the form of an explanation or directions,&quot; such as a cookbook, can be copyrighted but that a mere list of ingredients cannot receive that protection.&quot; In that regards, here's a recipe for liquid soap I found online! 16.5 oz. Sunflower Oil 7 oz. Coconut Oil 5.5 oz. Potassium Hydroxide KOH 16.5 oz. Distilled Water for the Lye Mixture 40 oz. Distilled Water to dilute the soap paste Either 2 oz. of boric acid or 3 oz. of borax mixed into 10 or 6 oz. of water Approx. 3 oz. Fragrance or Essential oil, as desired Soap dye or colorant, if desired Source: http://candleandsoap.about.com/od/liquidsoap/ss/basicliquidsoap.htm
Hi! Thanks for checking out my instructable. I didn't include a recipe not so much because of copyright issues but because I meant this just to be about the process. Recipes abound on the internet with just a simple google search. I also did say in the instructable (above) that I used recipes from Catherine Failor's &quot;Making Natural Liquid Soaps&quot;. I also included a link to snowdrift farms website for other recipes. I hope this helps. Yetunde
You make a point to say that the lye needs to cool down, but how much? What temperature? What temp should the oil be when you add the lye? Isn't that important? I'm so confused, and I'm starting to get mega-discouraged with liquid soapmaking. This would be my fourth time.... *sigh*
Please don't be discouraged! Once you get the hang of it, it's really quite simple. I will do an update to this instructable (and possibly a video) with more specific info, hopefully soon. I only meant this instructable to be general information to illustrate what to look for, but judging from what I'm hearing, people need more detailed information. To answer your question about the temperatures, I guess I didn't mention that because I don't worry too much about dropping the temps because it's not a huge drop. According to Catherine Faillor's book, you should let the lye cool down to about 140deg F (from the initial 150deg F that it rises up to). Tthe oils should be at about 160deg F. I will update with this info. Good luck, and please don't hesitate to ask if you have further questions.
Okay... <br/><br/>I've added my lye water to my oil. Following this method:<br/><br/><a rel="nofollow" href="http://www.youtube.com/watch?v=eJZ_eL4ponk">http://www.youtube.com/watch?v=eJZ_eL4ponk</a><br/><br/>And instead of a double boiler, I'm using a crock pot (propane is expensive where I live...)<br/><br/>My mixture is not thickening.... How long should I be mixing for? I've been at it about 15 minutes, and it's still quite watery....<br/><br/>Lye and oil added together at the aforementioned temperatures. <br/>
Oh, you're so sweet! I'm doing this as I type, letting my lye cool down to the degree you said. Thanks so much for answering my question so quickly! This project has been vexing me for a week and a half now!! *cries* Heck, thanks for just answering my question period!! Five different sources, and not one answer until yours! <3
If a person found it best to keep the soap in the condensed state, would it be best to neutralize the excess lye or not? Which do you think would keep longer? For example, I would only need a relatively small amount diluted, but it would be easier to do more at once.. My intuition says to not neutralize it to keep it less hospitable to nasties. Thanks
hmmm...that's a good question. Even diluted and neutralized soap doesn't grow bacteria or mold, from my understanding. What does happen though, is that it goes rancid after a period of time due to the fatty acids in the oils reacting with the oxygen in the air. So, diluted and neutralized or not, it won't grow any nasties, but it will eventually go rancid, probably faster if undiluted and neutralized because the fatty acids will be more concentrated. I think it's always the best practice to neutralize the remaining lye in the soap. I think your purpose would be better served to add an antioxidant (such as T-50 vit E) to your oils as soon as you get them, before making the soap. I hope that helps.
Thanks for the reply. A couple more thoughts.. One solution I was thinking about was using mason jars and either vacuum sealing or using a hot water bath to preserve it. If vacuum sealing, it would probably be best to neutralize as the fumes may deteriorate the sealer. If the oxygen is the problem, I would think the undiluted material would have less oxygen than the water it would be diluted with. Either way would probably be helped with the antioxidant idea.. Thanks!
good instructable, i was wondering where do you get lye? Also for the borax can this be found in the detergent aisle? (99 Mule something?)
Hi, and thanks for checking out my instructable. The lye for liquid soapmaking (Potassium Hydroxide) is a little harder to find than the one for bar soaps. You can buy some at either <a rel="nofollow" href="http://snowdriftfarm.com">http://snowdriftfarm.com</a> or <a rel="nofollow" href="http://www.diannassundries.com/">http://www.diannassundries.com/</a><br/>Yes, the borax is 20mule team and can be found at your grocery store in the detergent aisle. Good luck, and I hope this helps!<br/>
I was all good until the end when you said "check your book for ratios" This would be more helpful with a sample recipe.
I'm sorry you found it less helpful without a recipe. I simply wanted to show the process and give a pictorial guide. No matter what the recipe, the process is basically the same. There are also some free recipes online. Check here: <br/><a rel="nofollow" href="http://www.snowdriftfarm.com/form_liquidsoaprecipes.html">http://www.snowdriftfarm.com/form_liquidsoaprecipes.html</a> <br/>I am in no way affilliated with the book or the sites I've mentioned. These are just resources that I've found helpful.<br/>
Thanks for the link, I've got Catherine Failors book as well actually. i just think the tutorial would be better with a basic soap recipe included. But then ready the other comments, i now realize you weren't trying to teach soapmaking, just providing a pictorial of a new process.
Very cool soapmaking tutorial! I'll have to try this soon!
heh, funny this should come up on the front page the day I think about trying this.... how would you modify this to make solid soap? also, you don't mention any figures for the ingredients....
I didn't include the exact ingredients and measurements because I only intended this to be for experienced soapmakers who wanted to try their hand at liquid soaps. I also suggested in the instructable to read up in more detail about the process, as well as recipes. Catherine Faillor's book "Making Natural Liquid Soaps" is an excellent primer on the subject. As for making bar soaps, there are literally thousands of recipes online. Here is where I got my start 10 years ago: www.millersoap.com I did forget to mention that liquid soap uses Potassium Hydroxide lye (KOH) as opposed to Sodium Hydroxide lye (NaOH) for bar soaps.
I see, my apologies, i posted this rather late at night. I will take a look at that website, thank you.
Thanks for coming back, and happy soaping. The miller website was what got me hooked on soapmaking, so I think you will like it. I'd be happy to help if you have any questions either on bar or liquid.
Hi this put a new perspective on the way I have been making liquid soap &amp; hard soaps since 1985. I'm not sure if your way is easier will test it soon. <br/><br/>In relation to 2 issues regards the caustic or lye it will absorb into the oil more over time and with stirring causing it to as you say neutralize. 2 Potassium Hydroxide will only make true liquid soap not the borax. <br/><br/>Borax is alkaline 1 or 2 ph steps down from caustic. If you were to neutralize the rest of the lye use citric acid therefor bringing the ph down but use to much or to early and you end up with a box of nice smelling separated liquid NOT SOAP. I use only say 20 millilitres of 100% citric per kilogram of soap MAXIMUM to reduce the ph that is when I need to.<br/><br/>For bumpus check out my <a rel="nofollow" href="http://www.tecacentre.net/making_soap_info_hints_tips_recipe.html">23 year old tried &amp; tested soap recipe</a> this tried &amp; tested soap recipe is what I use each time for making hard soaps just adjusting my other ingredients.<br/><br/>The last recipe I added Honey &amp; cold tea instead of some of the water, the one prior to that I added a cup of skim milk powder to make a dove like soap.<br/><br/>Hope this helps<br/>Regards<br/>TJ <br/>From<br/>ausis.info <a rel="nofollow" href="http://www.ausis.info">Australian solutions</a><br/>
Thank you for your comment. I didn't state that liquid soap is made with borax. Of course you can only make liquid soap with Potassium Hydroxide lye (Caustic Potash, KOH). As to the pH of borax, I'm not certain. According to the book I learned from, you can use borax as a neutralizer for the remaining lye. The book also mentions the use of citric acid as a neutralizer for the remaining lye. I use borax mainly because of its dual purpose as a neutralizer and an emulsifier. The borax reduces the surface tension of the soap to keep it from going back solid in thicker formulations such as shower gels. My instructions also specifically states to add the borax at the end of the cooking phase at the point of dilution, when all reaction has been completed. I guess it's all just a matter of personal preference. For instance, I forgo the use of DiPropylene Glycol in my formulation, but it is present in yours. Once again, I do not intend my instructable to be the last word and the only primer for anyone wishing to undertake this process. It is meant simply as a guide and pictorial, because not many people know what to look for at each stage. Please refer to the book mentioned in my instructable.
Firstly you did a great job on your instructable. Sorry I was a bit straight forward before I was just trying to help out I was not meaning to sounds as though I was picking or anything. To clarify I only use DPG sometimes at a rate of 1 ml per kilo of soap mainly when I use lavender oil as a fragrance as it helps the trace stay in suspension. Lavender tends to cause the soap to separate otherwise. With the borax I read somewhere it is supposed to help reduce the build up of soap scum on the bath and showers. I personally do not use it normally as I use soft water therefor less calcium carbonate. Sorry again for any mis understanding. Just trying to be helpful.
Thanks for coming back! I appreciate your comments, I really do, and I didn't mean to come across as defensive either...must be the lateness of the hour. Our water is very hard here in Dayton Ohio, so we need all the help we can get. I didn't know anything about the DPG outside of it's use in room scenting. I'm still learning myself, so definitely no offense taken.
so does the continued cooking neutralize the rest of the lye?
no, the continued cooking does not neutralize the lye. the addition of the borax neutralizes the rest of the lye. hth, T
thanks for the comments. I decided to do this on liquid soap because there is sooo much info on the web for bar soaps. When you're 'in the know' you assume everyone else is, but I guess not. I just might do one on bar soaps too.
I thought it was really well done.
Awesome!, This is basically what we did in science class last year, but the soap we made was solid... Perhaps an instructable on that next time? :D
