Sodium Lactate - Sodium Lactate is a liquid salt that is naturally derived from the natural fermentation of sugars found in corn and beets. In food, Sodium Lactate may be used as a preservative, acting as an inhibitor of bacteria growth. In CP soap, Sodium Lactate helps to produce a harder bar of soap that lasts longer in the shower. Because Sodium Lactate is a salt, it is a natural humectant, providing moisture. This makes it a great additive to lotions, typically replacing glycerin in the recipe.

Usage rate: .5% - 4%, or 1 tsp per pound of oils.

Usage Instructions: Add Sodium Lactate to your water phase (cooled Lye water) when making Cold Process Soap.
Botanical Name:  Propanoic acid, 2-hydroxy-, monosodium salt
Common Name:  Sodium Lactate

My new Love
I used this in my Goat's milk soap and talk about a creamy bar. They were easy to remove from the mold and cut beautifully. Also have began adding this to my lotions. Especially since it is best to replace glycerin with, only in my lotion I still added the glycerin for the winter weather skin. Will be ordering more.

There is nothing that beats sodium lactate when it comes to HP soapmaking. It helps keep the batch more fluid so it is pourable.

I love it
i used it in my soap and i did get little white specs but for me its really no big deal, since my soap is for myself and my family. Other than that it makes the soaps nice and HARD which i love. Also this is a question. when i added it to my oils and lye it smelled funky for maybe a minute or two then went away, is this normal? thank you.

sodium lactate worked well for me
I used it for the first time in my new silicone mold, and the soap came out of the mold beautifully. It looked very nice also, but I'm wondering after the cure time what it will look like. I used the pomace olive oil and red clay in my soap and normally it would be yellowish out of the mold, but with the addition of the sodium lactate it came out nice and white with the red clay very vibrant looking. I'm just wondering if it will stay white or get darker as it cures. Can't wait to see.

Works for me
I am a beginning soapmaker and I have been using this in all of my cold process soaps. It makes the soap slide right out I the silicone molds. I had adjusted my recipe on my last two batches and I also ended up with pretty noticeable white specs in my soap. But then I realized I had used 1 tablespoon per pound of oil instead of 1 teaspoon. I corrected the error and my next batch came out perfect with no white spots and was nice and firm and ready to unmold the next day.
