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

Leaking bottle
I had the same problem as Michael. Half of the contents were leaked.

sodium lactate
I made many pounds of soap with this new product tweaking lots of other elements like temperatures, stirring time, fragrance insulation, and recipes. I think I figured out that I need to use it only with silicone molds and/or recipes in which the solid oils contain very little to no palm oil for reliable results. One worked fine that had 1/2 olive oil and half solids - coconut, shea, and palm, with palm being only about 1/4 of the solids. It had coconut milk as part of the liquids. I have been soaping about 15 years with no failures before this, but my soaps were mostly crumbly and a little spotted.

Bottle Not Full, No safety cap
Hello! This was my first time buying with this company after hearing great things. I really hate to ever write anything bad or negative about any smaller company, but I just had to share. I ordered this and Polysorbate 80, both of which came the same way. I ordered the 24 oz size which came about 3/4 of the way full in the bottle. The box that it came in had a oil/water stain at the bottom. Not sure if it was from this or the other product leaking out. Also, there was no safety cap and was not properly sealed. When opening the bottle, you can touch/see the liquid, as opposed to other companies having a plastic safety cap sealed on the top of the bottle (although I hate to use plastic, it does protect again the elements). I was not very happy with my order. I am hesitant to use this product (or the other) now because I don't know how/if it was stored properly (given the condition).

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!

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.
