It's important to note that these are just starting points, and the optimal concentration may need to be adjusted based on the specific product and desired effects. Factors such as the presence of other ingredients, the desired viscosity, and the pH of the product can all influence the appropriate usage rate of sodium lactate.

To use sodium lactate in soap making, follow these steps:

Ingredients:

-Soap Base (pre-made or handmade using the cold process or melt-and-pour method)
-Sodium Lactate (liquid form)
-Fragrance or Essential Oils (optional)

Instructions:

1) Prepare your soap base: If you are using a pre-made soap base, follow the manufacturer's instructions for melting and preparing it. If you prefer to make soap from scratch using the cold process method, follow a standard soap recipe and add the sodium lactate at the appropriate stage (usually after the lye-water and oils have been combined).

2) Measure the sodium lactate: The typical usage rate for sodium lactate in soap making is around 1-3% of the total weight of the oils in your soap recipe. For example, if your soap recipe contains 500 grams of oils, you would use 5 to 15 grams of sodium lactate. Be sure to check the specific usage rate for your particular brand of sodium lactate, as it may vary.

3) Add the sodium lactate: Once your soap base is melted (or your lye-water and oils have been combined in the cold process method), allow the mixture to cool slightly to a temperature around 120-130°F (49-54°C). Then, add the measured amount of sodium lactate to the soap mixture.

4) Mix thoroughly: Stir the sodium lactate into the soap mixture until it is well incorporated.

5) Add fragrance or essential oils (optional): If desired, you can add fragrance or essential oils to the soap mixture at this stage. Be sure to follow the recommended usage rates for your chosen scent.

6) Pour and mold the soap: Once your soap mixture is well mixed, pour it into your soap molds.

7) Allow to set: Let the soap cool and harden in the molds for the recommended amount of time. The addition of sodium lactate should help speed up the hardening process, and you should be able to unmold the soap sooner than if you hadn't used sodium lactate.

8) Unmold and cure: After the soap has hardened and can be easily unmolded, remove it from the molds and allow it to cure for several weeks. This curing process helps the soap become milder and ensures that excess moisture evaporates, resulting in a harder, longer-lasting bar.

That's it! By incorporating sodium lactate into your soap making process, you should notice improved hardness and durability of your soap bars, along with the added benefits of its humectant properties for the skin. Remember to always follow safety guidelines and recommendations for handling lye and other soap-making ingredients.
