I am aware of this Arimara, and the whisk is my friend.

Thank you for your advice.

The KOH adds solubility to a soap. This will be helpful for high oleic soaps (in other words, 100% olive castile and high OO bastile soaps) to quickly break down the goopy (snotty) oleic gel that forms with these soaps. It might also be helpful with a high stearic-palmitic (lard, tallow, palm) soap to help this type of soap dissolve and lather more easily. So I could see a bit of added KOH being useful as an alternative for some or all of the coconut oil or PKO in a recipe. I'm not sure how useful KOH will be in a highly soluble recipe, however, such as a soap high in PKO or coconut oil.

I have continued to test the mock castile soap I made with HO safflower and 5% KOH. I regularly compare this soap (8 weeks old by now) to a 2 year old castile made with 100% NaOH. The 5% KOH mock castile lathers much easier and more abundantly than the 100% NaOH castile. It has remained hard and long lasting with the usual precaution of keeping it in a well drained soap dish -- same as I do for all my soaps. The mock castile still has some of the nature of a 100% NaOH castile -- the lather is fairly dense and creamy and the wetted soap bar has the unusual slickness I associate with a high-oleic soap, but there is little or no tendency to make "snot" or slime.

I need to make a video....

Default Castile Dual Lye - 95%NaOh 5%KOH [40%Lye] - Results

I made two batches of this yesterday. Dual Lye Castile - 95%NaOh 5%KOH [40%Lye Concentration]

One batch was 50% Pomace OO and 50% Kirkland's Pure OO. Within a few hours it was rock hard! I was amazed even though I read that it would be, I still found it remarkable. I did NOT use my SB because of the pomace, only a spoon. Trace at about 7 minutes, but I should have stopped stirring at emulsion to separate & mix colors, because by the time I was ready to pour into the mold it was already at thick trace and my ribbon pour did not turn out ribbony.

I used 3 micas from Steph's Micas & More: Sunflower Yellow, Clementine & Orange Coral, plus the plain soap batter as one of the colors; scented with Mad Oils Grow a Pear Tree FO and Candlepro's Pearberry (50/50).

Even though the 'ribbon pour' was a failure as such, I still think they are quite nice looking, and they smell very nice, too.

Mixing temps about 110F. CPOP'd with oven wall temp at 137F when I put them in (oven was pre-heated to lowest setting & turned off.)




The other batch was 100% Kirkland Olive Oil and although I thought I did everything else the same, except bringing only to emulsion before mixing colors and waiting for light trace before pouring batter into long-spouted container, it did not turn out at all hard as I was expecting.

Maybe the mixing temps were different, as I did not write them down & don't remember. I doubled the recipe for this one, but double checked all my measurements at every turn. I did run into a problem with pouring the batter, in that being a double recipe, it was too much for my container. So the first mold (a one-pound mold) did not get an even shake at the ribbon pour. The bottom portion was more like dump it in fast before it spills all over the place. Ribbon pour on top was a bit more like intended, but not what I expected. I am not sure how many times I am going to have to try it before I am happy, but that's another story.

The other mold is a long wooden mold and I have not yet unmolded it because the soap in the one-pound mold is still so soft.

I CPOP'd these overnight, going into the oven at approximately the same temp as the other one had, covered both molds with cardboard & a light towel.

For color I used 5 micas + TD for a 6 color ribbon pour, and scented with BeScented's Strawberry Patch FO. Micas from Steph's Micas & More: Cosmic Purple, Silver Graphite, Vivid Violet Neon, Marvelous Magenta Neon, Radical Red Neon; plus one portion was colored with TD, for a total of 6 colors.

So far I only have pictures of the one-pound mold cut. You can see how soft they are as evidenced by the edges:

I just realized this probably should be in the Recipes Feedback section instead of Recipes and Tutorials section. If an admin feels that is the more appropriate location, please move this thread. Thank you.

If everything was the same between the two batches except from the pomace OO that was used, then this might be to blame as pomace has the ability to hasten saponification because of the bigger amount of free FAs it has, and thus the soap peaks to a higher temperature, saponifying more quickly the oils and maybe forcing more water to evaporate because of the heat at the same time. I think also light or thick trace affects a little the unmolding time.

Those issues must be the reasons for the harder version of soap.

Yesterday I made the two lye solutions too (dual lye and NaOH only at 38% lye concentration) and by tomorrow I will make the soaps (will post in a new thread).

I suspected as much, but not at such a large degree of difference between the two batches. I do believe I will use at least one-quarter to one-half pomace in castile from now on because it made such a great difference. Although I still would want just as long a cure time, I really like being able to free up my mold, and to put soap out to cure without fear of defacing the bars with fingerprints, etc. I really like not having squishy bars of soap to handle!

I am looking forward to seeing your dual lye soap, ngian.

Thank you, penelopejane.

That happened because I
1. poured the batter into the spouted container too thin, and
2. overfilled the spouted container and before it could start spilling over, I had to dump a lot of the batter into this mold immediately.

It's sort of funny because there was a split second of time from when my brain recognized it was going to spill over before my motor control kicked in. So I knew it was going to happen, but couldn't stop myself fast enough. My brain to motor control reaction time seems to be slowing down, so I'll need to remember to be more cautious.

Anyway the colors in the bottom of the mold got a bit muddled, then I as I began to pour slowly and carefully into the bigger container, the batter started to thicken. I actually filled most of the other mold before I finished the rest of this one, so the top layer had a better chance of staying where it was put without mixing in with the rest.

I'd like to get that wood grain look that newbie got in her green soaps, but I think neon colorants are not the best option for that. I'll try again with more subdued colors as I do have a few more micas to test.
