Splitting method with breastmilk

[Liorasol]

I’m so sorry if I’m posting in the wrong area (should I be posting in recipe feedback??) Moved

My sister has requested a breastmilk soap so I was thinking of using Zany’s Castile Soap recipe as follows:

Olive oil: 374.67g
Faux sea water: 50.23g
Lye: 50.23g
Breastmilk: 35.16g

I was planning on doing a master batch of lye solution and then adding the breastmilk directly to the oils before pouring in the lye solution.

Does this make sense or should I add the breastmilk into the lye once it cools? I’m worried about scorching (even though it would be frozen) since it is such a small amount of breastmilk for a small batch. Another thought is freezing the faux water portion as well to help keep the temp more manageable for the breastmilk.

Any help is very very appreciated

Never soaped with breast milk but do have a suggestion.

Don't freeze the breast milk and just add it to your oils. Make sure to soap at room temp or at least under 90F. Once poured into your mold, spray the top with rubbing alcohol and cover with cling wrap. Place it in the freezer for a few hours or overnight to prevent gel/scorching.

If you're doing individual molds I recommend leaving it covered for a week before unmolding. I've found pure olive oil soap tends to ash more readily than other recipes. But that's just been my luck.

When I use breastmilk I just dissolve the lye into frozen breastmilk and proceed as usual.

I did as KiwiMoose stated above. As much as I get freaked out soaping with breastmilk, a niece of mine begged me to make her a batch, and I did. I discovered it is a milk that soaps beautifully, but I would not waste the milk and ingredients on Zany's recipe. Granted, that is just my opinion because I hate that recipe. I made my nieces with lard, tallow, sunflower HO, and 15% CO. I also use a chelator EDTA and Sodium Gluconate in combination with a 2% superfat. It really made a gorgeous soap.

Is there a reason you did not like it? I just made a small trial batch of Zany’s recipe (without using the breastmilk).

Tallow and breastmilk would be my go to for this recipe tbh, I love anything with tallow in it! Next experiment hahah

The recipe will be affected by the substitution of the breast milk. So the ratio of water/salt will be less and therefore create slime.
When I made breast milk soap I just made my usual recipe but with breast milk instead of water

My kids are in college so I'm out of date on breatmilk. lol
Are there any saponification calculations/considerations for the fat in "milk"?

If you're not using 100% breastmilk instead of water, I'd suggest adding the milk after the lye has clarified in the water. If the recipe allows. I've had additived fall out of suspension if present for the dissolve process. Might be gentler on some of what's dissolved in the water portion of the milk.
