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

Very well-behaved for me. Love it!
My early soaps disappeared so quickly in the shower I thought I had a magician in my house. I also had a hard time unmolding them. Now that I've used Sodium Lactate, I really love the texture and staying power of my harder bars. I add usually just under a tsp per pound in my lye water when it reaches around 110-120 and pour the lye into my oils shortly afterward and mix. I have noticed my buttermilk lye liquid likes to get thick, so I've started waiting to put the SL into the milk/lye mixture only right before I combine with base oils (SL may not be the reason, but the timing was my best first choice of what to change). It works GREAT for me! just like a well-behaved, rarely fractious puppy :) It depresses me when I run out, so now I try to keep it always in stock. Thanks BB!

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!
