How to make handmade soap？Three ways to make handmade soap
1.Cold Process（The method used by the average handmade soap enthusiast, the method used by most high-end soaps）
In making it, the process takes about 1-2 hours, and then it needs to go through a maturation period before it can be used. The "maturing period" is mentioned here, and anyone familiar with handmade soap will have come across this term, but what is the "maturing period"? The first thing that you need to do is to make sure that the soap is ready.
The first thing that you need to do is to take some time to get the pH value of the soap down to a mild range that your skin can adapt to before you can use it, and this time is called the "maturity period"!
The length of the maturation period is different depending on the composition of the soap - that is, the oils and additives, generally 30 days or more, while household soaps and other household cleaning formulas can be shorter, more than 2 weeks on OK. If the cold handmade soap is used before maturity, it can be a big skin irritant!
The finished product is called "cold process soap" or "CP soap" for short.
The advantages: you can completely control the materials used to customize the soap you need; it can produce up to 25% natural glycerin.
Disadvantages: the production process is complex and even dangerous; the nutrients and fragrance of the additives are easily destroyed by strong alkalis; the maturation period takes a long time and is not conducive to mass production.
2.Hot Process（Can be shaped like clay）
If you feel that the cold process takes too long to mature and you want to speed up the process, you can use the hot process - heating the cold soap before it goes into the mold - to speed up the saponification reaction with the added temperature and make the soap ready for immediate use.
If you are making this at home, you can use the water heating method or the oven baking method: the former is to microwave or gas ovens over low heat for about 2 hours, and the latter bakes for about 50 minutes. The finished product using this method is called "hot soap" or "HP soap" for short.
Pros: You can have complete control over the materials used to customize the soap you need; the soap you make is immediately available.
Disadvantages: The process is complicated and even dangerous; the nutrients and fragrance of the ingredients are easily destroyed by high temperatures, especially the essential oils.
3.Melt & Pour（Rich in shape, often used as decorative items）
Use commercially available ready-made "soap bases" to melt, add color and flavor, and then pour into the model. There are many variations that can be created, and the rich colors and additives and fragrances often create a stunning effect. It is easy to make and can be operated by children under 12 years old with an adult, so it is suitable for parents and children to enjoy together.
Here it is important to further explain what "soap base" is.
After the saponification reaction, the glycerin component is removed, and the rest is called soap gum, which is adjusted with salt and water to separate the soap base from the impure material, the upper layer is the soap base (generally used as industrial soap or soap grains, industrial alcohol is added for sterilization purposes), the lower layer is called the soap foot (mainly for industrial use).
With this method, the soap can be completed within an hour, and the soap can be used immediately. Because the soap base is already saponified to complete the soap, itself can be used, so the finished product can certainly be used immediately. However, this method of manufacturing soap does not contain glycerin, but also added alcohol, the oils used (mainly palm oil and coconut oil, which is good foam coconut oil, but after washing the skin will feel very astringent) is not suitable for skin cleaning. If used for washing clothes is quite good, because the washing effect of coconut oil is still good.
The finished product is called "melt and reconstitute soap" or "MP soap" for short. It is also called "clear soap" because most of it is transparent.
Pros: The process is simple, does not require exposure to alkaline substances, and children can participate; there are many shapes that can be made; it can be repeatedly heated and melted, so there is no fear of wasting materials; and the production cycle is short.
Disadvantages: clear soap base does not contain glycerin and contains alcohol, not suitable for some sensitive skin, and not enough lathering.
