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

Seized My Batch--Wish I Could Give It Zero Hearts!
I used this sodium lactate with a CP recipe I have made dozens of times, with the same fragrance and never had any trouble with it....ever. With this batch, with this sodium lactate, my soap just seized! I mixed between 120 degrees like usual. I'm very frustrated and disappointed. I am trying to save it; it is in the oven; I really don't want to re-batch it. UPDATE: To their credit the BB team tried to help troubleshoot what went wrong, but after confirming my recipe ratios were correct, they were left scratching their heads. They felt perhaps it was the fragrance and/or honey I used in my oatmeal. (I've made the same recipe before many times w/ no problems). I just made a second batch today 8/22/15 with no fragrance and no honey. SAME THING HAPPENED!!! USE THIS PRODUCT AT YOUR OWN RISK AND OWN EXPENSE. I WILL NOT USE IT AGAIN. Add sea salt and sugar to your batch instead!

still soft
I was very excited to find out about this product. I have been having issues with removing cold press from silicone molds. As per instructions I added 1 tsp per pound. After 48 hours the soap still is too soft to remove from mold. You mentions about reducing water %. Could you explain this a bit more? Thank you.

Hi Darla! The Sodium Lactate will help to make a harder bar of soap! Though depending on your recipe it can still take longer to unmold your soap. Water discounting will also help you achieve a harder bar of soap with a shorter cure time. This is where you decrease the amount of recommended water in your recipe. Though, water discounting also results in reaching a medium/thick trace faster. For this reason we recommend this technique only for advanced soaps.

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!
