I have a question about the quantity of oils & salts to use when making salt soaps. Most things I have read seem to use a 1:1 ratio oils to salts. Will this make the batch bigger? If I have a mold that will hold 48.8 oz of oils (using the LXWXHX.4 method) and I add 48 oz of salt, will that double the batch size to 96 or will it still fit in the 48 oz mold? Thanks for any help!
 
You can use any ratio you want.. I've seen a few people use 1:1 (noone seemed to rave about it), a lot use 80% salt, some use 50% and 25% (and I'm sure others have more preferences). It doesn't increase the volume by much. When I first learned salt bars, the rule of thumb I was told (and found to very accurate) was to use 80% of your original oils and 80% of that number for salt, and that it the same size mass as you would have in a normal batch.
 
uh...no...if you have 1lb. of oils and you ADD 1lb. of salt (or 12.8oz. which would be 80% of oil) it WILL increase the overall size of your batch. Not necessarily by the exact amount of salt added, but it does.

:wink:

I don't have an exact formula or anything...but I use 80% salt to oils, so I just played around with it, guessing at first...to make a batch size to fill my mold. I had to DECREASE, though, the amount of oils for it to fill the same size mold.

ETA: I just had some individual molds on hand when I did the first batches, to fill with the overflow of batter...and THOSE soaps turned out better than the ones in the big mold! :)
 
If you decrease your original oil amount to 80%, and add 80% (from that number) of salt... It will be the exact same volume as if you used your 100% oil..

48.8 oz x .80 = 39.04 oz oil
39.04oz x .80 = 31.232 oz salt

I learned that from this forum a few years ago :)
 
Thanks for the tips! I'll try that 80/80 rule and see how that goes. Maybe have a couple of extra molds standing by just in case. This will be my first attempt at a salt soap and I want to do as much research as possible before trying it. Now I just have to wait for my leave to start next week!
 
When I started making salt soap I had no idea of the amount I would have, as I'm lousy at working out volumes etc.

I had researched for some time and decided on 70% salt to my 95% co and 5% castor oil ... 20% superfatted. This research also convinced me to use silicon moulds and I chose the muffin shapes and any left over went into a silicon loaf mould.

I've now resized my recipe ... due to my earlier trials ... and have a recipe that fits the number of muffin moulds I have.

I (my family and friends) love salt soap!
 
I've done alot of salt soaps. They're pretty popular with my soapy circle.
I've pretty much settled into 80% of total oil. With some castor & shea.
I do find it increases my total batch weight but doesn't double the actual quantity. Maybe 1/2 again. They r good heavy bars though & last & last.

I threw a 7month old bar in the shower this morning actually. I never have really given my salt bars enough of a chance to age as they go so quick & I can't seem to get in front with them. Anyway, long story short, keep as batch aside for mwa, this bar I threw in one of the best salt bars I've used to date.....salt bars are definitely better with age!!
 
nattynoo -

I agree. Salt bars are much better with a longer cure.

That's a great formula for figuring out the batch size. Thanks for posting it.
 
Made some last night. I think in 7 months it willbe hard enough to drive nails

7 months! Is that a joke or do they really need to cure that long? I was hoping to make salt soap sometime this week or next and have them ready for Christmas presents. Is there enough time?
 
LOL.... u don't have to wait 7months.....hehehehe.
U could use them after a few days if you really wanted too. As long as saponification has finished & there is no zap (though its hard to do a tounge test for zap with salt bars I find).
"its said" that salt bars get better with age.
So in theory the longer you leave them the better they get.
That particular batch I was talking about is at least 7months old & its truly lovely.
Usually though for me I cure them for about a month.
Not sure what the weather does for where you are but where I live its hot & humid most of the year & my salt bars sweat for awhile. Eventually they stop. So don't b surprised by that.
Salt bars are pretty cool.
 
Thanks! Had me worried there a second. I live in the Pacific North West. There is plenty of water in the air, but not heat. I'm almost ready to try salt soap! All I need to figure out next is what to use to form it. Risk using my loaf mold & them not turning out great or trying the individual mold idea.

Any advice/ideas on what to use for individual molds? I make small batches that usually yield about 12-14 5 oz-ish bars.
 
I know my salt bars get better with age. After at least 2 months, I can tell a difference.

Do you have any silicone muffin trays? Those would work.

High humidity is bad. Especially for salt soap. Hot makes it worse. Even if cool you may still have issues with sweating/condensation.
 
It has been 95 and HUMID for the last 4 or 5 days. Still no sweating, but I guess A/C helps. I made a batch Friday and couldn't wait. Used it in the shower Sunday. We loved it. Can't wait to see what it is like in a month.
 
I made a salt soap 2 weeks ago and tried it on my hands yesterday. It was 16 oz. of oils and 16 oz. of sea salt. I followed a recipe I found online, it was 12.8 oz. of CO & also had a bit of Avocado and Castor.

Anyway, I could not believe how sudsy it was. Sudsy and ..lotion-y.
I just made the same recipe again, but this time used individual molds and 80% salt. I added my salt at very thin trace, I was afraid I would have lumpy soaps, but they came out pretty smooth. I like them because the molds are smooth rounded rectangles. I'll try to wait longer with these.

I've heard 80% salt volume is more the norm, but I have to say, those 100% ones were really nice. Just wondering, what does less salt do for the bar?
 
I think less salt would mean it wouldn't be as scrubby.

I should tell you that you inspired me to play around with salt percentages. The salt bars I did last week are 100%, 65% and approximately 40%. The ones I did on Monday are 75%. It will be interesting to see how they turn out because I've been using 80% for all my batches since last summer. Who knows? I might find that I like a different percentage. :D

I think we all inspire each other, daily :)

That's cool, though, I'd love to hear what you think of the difference's, percentage wise, keep us posted!

Oh, and another thing I was wondering about- the recipe I followed had a 20% water discount. The batter becomes so thick so fast, wouldn't it be advantageous to use full water in the case of salt soap? I'd think a little extra working time would be good, especially when pouring into individual molds, but maybe I'm wrong about this??
 
I personally work with full water with my salt bars. I'd imagine all that salt would be thirsty. I've tried a few batches with lower water & I've had trouble getting them into the mould quick enough , plus I like to do a texture top & it left no time for the top.
