Also question is, how much lye do you need for soap?

Divide the amount of lye by 0.3 and then subtract the amount of lye from the result. For example, to make just over 2 pounds of olive oil soap, measure 32 ounces of olive oil and 4.33 ounces of lye because 32 ounces of olive oil × 0.1353, which is the saponification value for olive oil, = 4.33 ounces of lye.

Additionally, how do I know if my soap is lye heavy? If it “zaps” you, it is likely lye heavy. The zap is hard to describe, but you will know it when you feel it. Do not the zap test if the soap is seeping, as the liquid may be unsaponified lye that can burn your tongue. If the soap doesn't zap you, it is likely safe to use.

Also asked, what happens if you put too much lye in soap?

When soap is made with too much lye, it is called “lye-heavy.” This means there is extra, free floating lye that was not made into soap during the saponification process. Lye heavy soap can be irritating when applied to the skin and should not be used or sold. Lye heavy soap is often crumbly or dry feeling.

How do you calculate lye concentration?

Those numbers are correct as stated. The math to calculate lye concentration from the weights is this: Lye concentration = NaOH wt / (NaOH wt + water wt) X 100 = 6.14 / (6.14 + 12.48 ) X 100 = 32.975

5. When fats and lye both reach about 100° F, pour lye into pot of oil and stir.

What is SAP value in soap making?

Soap Making: Saponification and SAP Values. These saponification values are also known as a "SAP value." This SAP value equates to the number of milligrams of KOH (potassium hydroxide) it takes to convert or "saponify" a fat into soap. It is the average molecular weight of the amount of fatty acids present.

Can I Rebatch lye heavy soap?

Since lye is caustic, lye-heavy soap is also irritating to the skin. If your homemade soap is too lye-heavy, check the recipe you used to see what might have gone wrong. Instead of throwing away the lye-heavy soap, you can rebatch (hand-mill) it and make it into a more balanced, non-caustic mixture.

How do you harden homemade soap?

How to Get Harder, Longer-Lasting Homemade Soap

What is false trace in soap making?

You may be dealing with “false trace.” Trace is the point in soapmaking when the oils and lye have started to saponify. False trace can look and feel like thick trace, but happens very quickly after the lye and oils are combined. False trace looks like thick trace, but the soap hasn't fully emulsified.

How do you keep soap from cracking?

3. Dip the pH strip in the bubbles.
4. Check the pH strip against the chart included.

Can you remelt soap?

Rebatching is taking soap that has already been made and giving it new life it by grating it, melting it, and then adding any additional colors, fragrances or additives you want. Think of it as a soap "do-over." Though some will call it such, it's not really "milled" soap as we've come to know in the stores.
