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

not so hard soap
I used SL for the first time in a 2lb CP batch. I waited 2 days before taking it out of the mold and it is still pretty soft. I left imprints in the loaf. Did I do something wrong? I haven't cut it yet because I'm not sure if I should wait for it to harden up a bit. I used the recommended amounts so I'm confused. I don't want to create more batches using SL if I'm doing something wrong. Help!

Hi Glo! While sodium lactate does help your soap unmold faster, if your recipe has a lot of soft oils, like olive oil, it can take at least 3-4 days to release. Also, you want to make sure to add 1 tsp. of sodium lactate per pound of oils to your cooled lye water. You can find out more in this Sunday Night Spotlight on Sodium Lactate. I'll be emailing you personally to find out more about your recipe!

A "natural" ingredient in my all natural soap?
I love using sodium lactate in my CP soaps and notice a nice improvement in firmness when it is going thru the curing stages. Is sodium lactate considered a "natural" ingredient in my "all natural" soaps? Where can I find a list of common ingredients used in soap making which are actually considered "natural"?

Hi Lucy! I'm so glad you like this product! Sodium lactate is a natural product. You can find out more in this Sunday Night Spotlight: Sodium Lactate. Also, "natural"  is an umbrella term that can be applied to almost anything that comes from nature, like these Brazilian clays. This Natural vs. Organic post has more information on the subject, as well as the natural products we carry. I'll be emailing you to discuss this more!

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.
