Ans. 1. No, you need to leave your soap to set at normal room temperature, no need to place it in fridge or freezer.
A big water discount can make soap harden very quickly. The oils you use can make a huge difference. A large percentage of coconut oil makes soap set fast. If you soap at high temperatures you can force saponification.
Yes, it's just fine to put your soap in the refrigerator. It will still be soap and clean you.
Use Hard Oils and Fats
Hard oils and fats, such as coconut oil, palm oil, palm kernel oil, tallow, lard and shea butter, are known for their ability to produce a harder bar of soap. These oils contain higher amounts of saturated fats than soft oils, which create a more solid structure in the soap.

To sum up the answer to the question: “When can I use my soap?” in the most commonly known and widely familiar response: You're free to use your cold process soaps in about 4 to 6 weeks; as soon as the bars have reached full cure.
Soaping temperature can make your soap soft :
Soap can take longer to set if it's kept in a place that's too cold. The saponification process, which turns oils and lye into soap, is effected by temperature. Cooler temperatures delay or slow down the saponification process while hot temperatures speed it up.
If by chance you have an actual liquid soap, (there are a few out there but just not that common) and you try to evaporate the water out it will get thicker and become more like a gel. It will never get hard like a bar of soap because it is a potassium salt and bar soap is a sodium salt.
Keep them out of the water stream.
If your soap bars are in the stream of water, or even being splashed with water during your shower, they're going to melt faster, leave more soapiness on your shower ledge, and honestly just all-around be a less enjoyable experience.
How Long Does Handmade Soap Last? You'll be amazed at just how much longer natural soap lasts than its commercially manufactured counterparts. You can expect 1-2 years in optimal conditions! The truth is, though, quality natural soap bars should be used much faster than that.
After the soap is made, it takes about 24 to 48 hours until it is un-molded and cut. Cut soap 36 hours after it was made. Once the bars are un-moulded, sliced and set on the shelves (racks), the curing period starts. The place where the soap is cured needs to be an airy, out of direct sunlight, and a dark place.
Ideally, 4-6 hours will be enough for the soap in the molds to harden enough to be removed. If not, the molds can be placed in the refrigerator for 10-15 minutes to facilitate the hardening process, though this should be avoided if possible. Once unmolded, the soap bars will be ready to use.
Palm oil hardens soap and creates lather with coconut oil. It can be used up to 33%. Palm kernel oil creates a hard bar and is recommend up to 15%.
ALL soap is safe to use after 48 hours. The process of saponification in which fats (oils, butters) and alkali (sodium hydroxide) combine to form soap only takes 48 hours.
You can add that chemical, sodium chloride, to soap and make it harder and longer lasting. You can also use sodium lactate — another chemical.
Stearic Acid or Beeswax
Both of these ingredients will harden your soap. Both of these ingredients can also be tricky to work with. You have to soap at hotter temperatures to make sure they don't solidify in your mixing pot.
One fundamental way to make your bar soap last longer is by incorporating hard oils into your recipe. Oils like coconut oil, palm oil, palm kernel oil, tallow, lard, and shea butter are rich in saturated fats, creating a solid structure in your soap.
Allow the soap bars to cool completely at room temperature. 4-6 hours will be enough for the soap in the molds to completely harden, and then it can be removed. Take it out of the molds, and it is ready to use right away.
Soap can be used before it's fully cured, but since it's not really finished, and therefore not as hard as it will be, non-cured soap won't last anywhere near as long as bars that are allowed to finish.
A soap made with salt will be very hard, which can be incredibly beneficial, because it means it will last for much longer. A salt soap is perfect for constant hand washing, or for your daily shower.
Then you can do the "zap test." It involves tapping the soap lightly on your tongue. It sounds weird, but it totally works. If the bar “zaps” you, it's likely lye heavy. The feeling is hard to describe, but you'll definitely notice it.
