Using Sodium Lactate in Cold Process Soap

 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.

Use of Sodium Lactate hardens the soap in a few hours, making it ready to use much faster.     But beware, use too much and you end up with a very dry crumbly soap that won't cut.    It also does not seem to pipe well, so avoid if making cupcake soaps.    Because SL does indeed harden soap quickly, be sure to cut within a few hours, otherwise it's just too hard to slice well.   

It will also cause seize, so beware.
