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

This stuff is good! I just unmolded a loaf from the 10 inch silicon mold and I was having one of those days where I was all thumbs. I stabbed the soap twice with my nails and dropped it once, and still came out unharmed! I'll never use a silicon mold without it!

Crumbly soap?
After a few failed attempts with this due to a miscalculation in my recipe, I've finally got the use of this product pegged. I LOVE IT! When I use Sodium Lactate in my soaps, they have outrageous, fluffy bubbles. I have done test batches of the same recipe with and without the Sodium Lactate. The soaps with the SL are WAY more bubbly and conditioning to my skin. I put this is ALL my soaps! LOVE THIS!

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!

What went wrong?.
i did two batches of cp. Using wooden mold. My total oil weight 1650grams. I used lye calculator. I added 1tbsp sodium lactate when my lye solution reached 130*F before adding it to my oils mixture. First loaf is my coconut-lime. I decided the entire mixture into 3 parts before I added my colorants. Used my hand blender to mix until it reached a light trace in all three. Pour to my wooden mold. Did my chopstick swirl. Tap to remove air bubbles. Spray with my alcohol. 24 later was excited to cut. I noticed that my soap has some liquid oil which didn't solidify. I did my 2nd batch with lemon grass - Rosemary with my frozen ginger juice. Ginger juice mixed with water was iced 24 hours ahead before I added my lye. At 130*f added my 1tbsp sodium lactate. This time I decided to color the entire mixture with very pale green. But I panic, it formed into a very thick mixture so quick. Quickly pour the mixture to my mold. It had a texture of a soft clay. There was liquid oil found after 24 hrs

Hi Imelda! Oh no! I'm so sorry that happened to your soap. I can tell you that the Sodium Lactate would not have caused that oil separation. Usually separation like that is caused by the fragrance oil. Read more about separation in the Soap Behaving Badly blog post. I will email you personally to help troubleshoot!

I like this product but I would like to know the concentration of sodium lactate versus the quantity of water of the product. Maybe Ishould perhaps reduce the amount of water in the lye solution. Thanks for your help.

Terah from Bramble Berry replies...
Hi Line! The Sodium Lactate is 60% water though you should not discount your water quantity for the lye solution at all! You only need to add 1 tsp Sodium Lactate per pound of oils. For more information on this product check out our Sunday Night Spotlight: Sodium Lactate blog post. I will email you personally to discuss this further.

Liquid temperatures
I just used this product and can't speak to the full results yet but it did seem to come out of the mold easier. I have an alternate formula that adds Beeswax, can this product be added to hotter lye/water mixture? If I am using a recipe with Beeswax, the recommended oil temps are 170 degrees and I have had good results at these temps so can the Sodium Lactate be add to the liquids/Lye mixture at say 150 degrees? What is the reason behind adding to "cooled Lye water"? What would happen if added to higher temp liquids?

Terah from Bramble Berry replies...
Hi Brock! I'm so glad your soap came out of the mold easier with our Sodium Lactate! Great question! You can add your Sodium Lactate to a higher temperature of lye (150 degrees for your beeswax recipe). The reason we recommend adding the Sodium Lactate to your cooled lye water is for safety concerns. When you're mixing it into your higher temped lye water you will want to be very careful and keep your safety gear on! I will email you personally to discuss this further.
