Hi FGOriold! Thanks for this input. I can find HEC on my usual suppliers' websites, but am having a hard time finding HPMC. I've checked www.saveoncitric.com, www.lotioncrafter.com, www.bulkapothecary.com, as well as Brambleberry and some of the other regular soap making sites. Can you please tell me where I can purchase HPMC online? Thanks in advance!!

You can find HPMC at The Herbarie:http://www.theherbarie.com/Hydroxypropyl-Methycellulose-HPMC.html
I thought Lotioncrafters used to sell it, but don't see it on their site anymore.

Faith, didn't you post on FaceBook about a trial you did recently using sodium citrate to thicken your LS? Intriguing!

Yes DeeAnna - I was able to easily thicken 2 soaps (One was 100% olive oil the other was 50% olive oil, 30% coconut oil and the rest other soft oils) with very small amounts of a 20% sodium citrate solution. The 100% coconut oil soap did not thicken at all. There was also no change in pH like with citric acid. The reason I chose to experiment with this was for potential chelating properties in addition to the thickening.
Olivem 300 also thickens these soaps but it is an emulsifier and they can sometimes cause me problems if the soap is superfatted or has FO/EO's added to them.

Thanks for sharing, Faith!
Small amounts of Potassium citrate, be it liquid or powder form, can also be used to thicken fairly nicely.
I'm posting this on a little outdated thread. However it seems to be relevant to the context.
I've been looking to replace my LS thickener from Salt to something more stable and does not reduce the lather. read about HEC and HPMC in this thread and few other places. I wanted to know the GRAS grade of these ingredients and any other concerns relating to use of these as thickeners. While doing some web search I cam across the below report, from the journal of American Collage of Toxicology titled Final Report on the Safety Assessment of Hydroxyethyl cellulose, Hydroxypropyl cellulose, Methyl cellulose, Hydroxypropyl Methylcellulose, and Cellulose Gum
I'm still into reading few pages only. However it seems to be very relevant to us and gives some insights to possible degradation that can happen and certain combinations which can give greater viscosity than single use etc. I know not every soaper like to go through the scientific journals. However these can help us formulating better products. Hope the community benefit from this.

Crothix here too! I try to stay as natural as I can but sometimes the results are better with less than "natural" ingredients!
I made sodium citrate solution using citric acid and baking soda. I added approx 3ml to 600ml of diluted LS soap (which has approx palm 55%, coconut 20%, olive 5% & sunflower 20% oils). This soap is actually a hybrid soap with 20% NaOH & 80% KOH. I wanted to figure out a different thickener instead of table salt as my soap tend to gel with little drop in room temperature. However 3ml solution did not improve the viscosity. Do I have to add more citrate?, Does citrate solution also have same effect as Table Salt in the lather?
Thanks for the link Lankan ... On page 3 of this 1986 edition of the Journal of the American College of Toxicology (according to the title), it mentions that the use of these cellulose thickeners also requires a preservative for long-term storage success. This is not a criticism, but it is worth noting that cellulose is food for bacteria, whereas salt is not

Yes. I also noted it, is't it specific to HEC. No such issues mentioned under HPMC or other types of thickeners discussed.
like I said earlier, I'm looking into these thickeners as I find salt less consistent with performance and sometimes given undesirable results. Also it's said to reduce lather.
My quest is to formulate a liquid soap without or with minimum use of synthetic or controversial chemicals.

Please, I will like you to share a full step by step method on how to achieve thickened soap with your formula
This is a really old thread. Deda hasn’t been here in a very long time. You may want to start a new thread and ask for assistance. Be sure to include your recipe and process. Welcome!
Thank you for your information. I am making a 100% olive LS today so will try this thickener

I have experienced this as well! Xanthan gum is 'good' but I got goopy, clotted liquid that was not good visually.
Regarding salt, I tried once before but it can only thicken so much that it doesn't work on massive batches, and a little bit too much salt will irreversibly transform your 'thick' liquid back to thin.
If you don't want to use anything sulfate/silicon-based, I heard a brand name of TEGO Remo 95 MB that could thicken a liquid soap like magic. I have yet to try it but will do soon, so wish me luck for that one. I'll post another one to update you on this.

I recently got some of this - Free Nivea Hand Soap | Just Free Stuff | UK Freebies, Free Samples and Free Stuff and found that it was too thick! So I wouldnt make it too thick or it could ruin the soup.

Borax is same of salt please?
No, it is not. I don't know if you can find Borax in the part of the Phillipines where you live, but there are places in some areas where it is sold. Buying Borax in the Philippines
Some Tagalog translations for Borax that may help identify it in your stores. But if you are not looking for Borax, and just want to know if it the same as salt, no it is not.
Earlene is right -- table salt is not the same chemical as borax.
If you study chemistry, you will learn there are many different kinds of salts. The salt we use on food is only one kind of salt -- table salt, also called sodium chloride. Other salts that soap makers often use include borax (sodium borate), sodium lactate, sodium citrate, sodium acetate, washing soda (sodium carbonate), etc. Even soap itself is a salt.
