Through careful testing, we can say that adding salt does indeed increase the hardness of soap. Yet, it only makes soap harder while it's curing. Adding salt does not result in an overall harder finished bar of soap, but it does make the bar get harder faster.
Sodium lactate is the liquid salt of lactic acid. It's generally added to cooled lye water at a rate of 1 teaspoon per pound of oils. If you don't have sodium lactate on hand, you can also add table salt to your lye solution. In the Palm Free Vertical Twist recipe, we used about 1 tsp.
There are other options for increasing the hardness of your soap beyond sodium lactate. In soap making, you can use 1 tablespoon of sodium chloride — that's plain old table salt, per pound of base oils to harden your bar. Dissolve the salt in a warm solution of water and lye for soap.
Liquids: Reducing the water amount will make the lye solution stronger and speed up trace. Using the full water amount recommended by most soap calculators may create soaps that visibly shrink during cure time, however. Additives: Sodium lactate is often added to soaps for hardness, but it can also slow down trace.
Here are five things that can yield a harder bar:
- Use a water reduction. Lye needs to be dissolved in water in order to turn oils into soap.
- Add some wax. A small amount of beeswax added to the melted oils will help harden your soap.
- Add sodium lactate.
- Increase the olive oil.
- Add some salt.
Sodium lactate is not routinely allowed for use in products labeled “natural” but it has been approved for use in certified organic products. According to the Federal Register (Vol. 74, No.
Lactic acid powder is not often added directly to soap. If you decide to try this, I suggest 5 to 10 g lactic acid per 1000 g oils (0.5% to 1% ppo).
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste.
It does not require working with lye, and is easy to customize with color, fragrances and molds. While usually considered an “easy” project, melt and pour can be a little finicky when it comes to temperature. If melt and pour gets too hot, the base will burn and becomes difficult to work with.
Melted soap is thin and fluid, so heavier additives can sink to the bottom. It cools and hardens quickly. That means some swirls that can be made with cold process aren't possible with melt and pour. Melt and pour soap can burn, which makes the base thick, gloopy, and difficult to work with.
Compound Sodium Lactate (Hartmann's) is used to replace body fluid and mineral salts that may be lost for a variety of medical reasons. It is especially suitable when the losses result in too much acid being present in the blood.
While the soap will never go bad, mold, or have a rancid odor, it will lose moisture over time. The soap will still be perfectly safe to use, but it will become dry and brittle. If this does happen you can add small amounts of glycerin to replace what was lost.
Like “true” soap, Melt and Pour soap has been made through the saponification process with a combination of ingredients that are also used in traditional soaps – which might be considered to be more “true” – and these include natural oils as well as lye, thus Melt and Pour soap does not need to have lye added to it, as
Answer: You can add a small amount of beeswax or stearic acid (up to 1 tbsp per pound of soap) to your melt and pour soap base but it will reduce the lathering properties of the soap. I've heard as well that you can leave the soap out in a dry location with a fan on it for a few days before wrapping it up.
A preparation method for mass concentration 60~65% sodium lactate solutions, comprises step:
- sodium hydroxide solution is added dropwise in lactic acid;
- during when pH is 5.0-6.0 or for 8.0-9.0, stop dripping;
- accurate drop reaction mixture;
Depends on what you mean by "regular" a standard bar of soap you buy at the store is about 3.5 oz or so. 2lb of soap is 24oz so roughly 6 bars of soap. Melt and pour doesn't need to have anything else added to it, so right out of the bag you can melt this down and pour it into a mold.

Sodium lactate is the sodium salt of lactic acid, and has a mild saline taste. It is produced by fermentation of a sugar source, such as corn or beets, and then, by neutralizing the resulting lactic acid to create a compound having the formula NaC3H5O3.
Sodium lactate is the sodium salt of lactic acid. With a hydroxyl group adjacent to the carboxyl group, lactic acid is classified as an alpha-hydroxy acid (AHA). Sodium lactate is also a natural constituent of the stratum corneum (the uppermost layer of skin) as a part of the NMF (Natural Moisturizing Factor).
Sodium lactate is just the sodium salt of lactic acid, so it is typically vegan. Sodium lactate is naturally produced in the skin and also naturally occurs in human and animal muscle tissue. It is also made from the fermentation of sugar that usually comes from corn or beets.
Sodium Stearoyl Lactylate (SSL) is another fantastic emulsifier that helps stabilize oil-in-water formulations such as a lotion. SSL is a natural, food-grade emulsifier derived from the sodium salt of lactic acid.
Lactic acid is specifically used to treat hyperpigmentation, age spots, and other factors that contribute to a dull and uneven complexion. Other benefits of AHAs like lactic acid include improved skin tone and reduced pore appearance. However, unlike AHAs such as glycolic acid, lactic acid is a bit milder.
Sodium lactate is most often made by the fermentation of a sugar, which can come from corn or beets, to produce lactic acid. Tom' uses a sodium lactate derived from corn. The fermentation product, lactic acid, is neutralized to create sodium lactate.
Sodium Lactate is an edible material that has been used for decades in the meat-packing industry because it effectively forces cells to hold water.
