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

Another name
Is this the same as Acid Lactic?

Hi Noelia!  I'm so glad you love our Sodium Lactate! Though, Sodium Lactate and Lactic Acid are not the same.  Sodium Lactate is the sodium salt of lactic acid.  They would not achieve the same results in your soap.  I will email you personally to discuss this further.

Great Stuff
I got tired of always having the corners of my soaps stay behind in the silicone molds when i took my soap out so i decided to try this item and oh boy was i pleasantly surprised at how well it worked. Affordable way to make your soaps harder and release perfect from the mold.

I read al the reviews and decided to try it. I always hate taking the small guest bars out of the silicone mold. I waited the normal time for this batch and HOLY COW the slats just separated from the soap and 'poof' I was done. It was awesome! It might have accelerated the trace but I still got it done. I used it again tonight on some small molds that I just got for embeds in the soap. I did not notice any acceleration on these at all. I can't imagine what I have done without it all this time!

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!
