How long after saponification can you use soap?
After saponification your soap is safe to use. You can technically use a bar of soap 24-48 hours after making it. But should you? This is where the cure time comes in. The cure time is all about water evaporation. During the cure time water dissolves from your soap creating a harder and longer-lasting bar in your shower. Curing = drying.
How long does it take for olive oil to saponify?
Those oils which saponify the most slowly – like olive oil – will still need another MONTH to saponify at that point – they can take up to six weeks to fully saponify. If you use the soap too early, it may still contain active lye in the soap. Active lye that has not been saponified is dangerous because it can burn or irritate the skin.
How long does it take to make homemade soap?
For some types of soap, salt is then added to precipitate the solid soap. The saponification generally takes about 24 to 48 hours to complete once the lye and oils have been mixed and the raw soap has been poured into the mold. This process can be sped up by adding more heat or slowed down by keeping the process cold.
How long does it take for saponification to take place?
This process usually takes about 24-48 hours to occur. During saponification the sodium hydroxide and oils are binding, doing their love dance and turning into salts of the fatty acids. Glycerin is also produced and if you superfatted (which we do), you’ll have unsaponfied oil as well. Heat quickens saponification.
How long does it take for cold process soap to Saponify?
Making sure the saponification process is completely complete generally takes anywhere between 24–48 hours.

Saponification Explained. In simple terms, saponification is the name for a chemical reaction between an acid and a base to form a salt. When you make soap using the cold process soap making method, you mix an oil or fat (which is your acid) with Lye (which is your base) to form soap (which is a salt). How exactly does this happen?
What is the base of soap?
The base must always be composed of one hydroxide ion. For the most part, people use lye (one sodium ion and one hydroxide ion) as their base. You will notice that the sodium ion does not take part in the reaction at all. For this reason, other bases like potassium hydroxide can be used as well because it too is made up of one hydroxide ion. Potassium hydroxide is more prominently used for liquid soap making.

What happens when soap is heated?
One thing that can happen when working with soap at high temperatures is the “soap volcano.” When this happens, the soap begins to boil up and may even come out of the soap pot if not supervised and stirred down from time to time. A simple solution prevents a mess: place your crockpot into the basin of your sink before cooking your soap. Another problem, especially with a high olive oil content recipe, can be soap that is slow to trace. Since you will want a medium trace for this soap, sometimes the stick blender can overheat before the job is done. Simply alternate one minute of stick blending with five minutes of resting until the desired thickness is achieved. Finally, because hot process soap can be harder coming out of the mold, sometimes after 24 hours it is so hard that it must be cut with a knife instead of a wire slicer.

Why is goat milk soap brown?
Liquid goats milk can cause the saponification process to significantly heat up, which can cause the soap to seize , overflow from molds , and brown. In order to try to avoid these problems, many soapmakers chill their liquid goats milk until it is "slushy" and near freezing. Then they add their slushy goats milk to their lye water before combining with oils. Also, most soap makers that use liquid goats milk generally do not insulate the goats milk soaps….this is an attempt to offset the extra heating caused by using goats milk.
