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

Amazing Product
How have I lived without this product?! It has made such a huge difference in my milk soaps. It even helps all the soaps come out of the shaped molds - perfectly. I will make sure to always have this product on hand. I love Brambleberry!

Crumbly soap?
I purchased this awhile back and just got the opportunity to use this. I used .15 oz added to my room temp lye water (12.55 oz water + 4.72 oz lye). I used 33 oz of oils for my calculations. When I unmolded the next morning, my soap was crumbly and brittle on the bottom. I tried to cut it, but on every bar, the soap crumbled. Did I calculate too much? Or too little? The soap has WONDERFUL, delightful bubbles however. I have used this recipe before and the previous soap doesn't have these outrageous bubbles-LOVE IT! Does sodium lactate increase bubbles as well as hardness?

Hi Christi! It looks like you used less than the recommended amount of Sodium Lactate so that would not have caused your soap's crumbliness. I will email you personally to help troubleshoot!

I am not sure what is going on with this product..It said to have lye water cooled..What temperature do you consider cool? I have let it get to 100 degrees then the SL to it..I also thought the oil and lye should be about the same temperature before mixing..I stirred it really good then mixed it with my oil to trace..I still have white spots in my purple colored lavender soap, and others..I have read everyone's review and still can't get the white spots out..Please help because I really do want to use this product..

Hi Carolyn! I'm sorry to hear you had troubles using this product. We haven't experienced this when using our Sodium Lactate. I will email you personally to learn more about why this might have happened.

Must have!
What a huge difference! My soap is noticeably harder and even the color seems more shiny and consistent! This has made all of my batches much more professional and sharp. HG product for me : )

Another name
Is this the same as Acid Lactic?

Reply from Bramble Berry
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.
