For example, all kinds of soaps we use in our daily life are made of alkaline substances, and we need to pay attention to avoid direct contact with alkaline substances. Today, let's take a detailed look at the process of making soap with potassium hydroxide.

1、我们首先是需要将碱性物质倒入到水当中，然后将其搅拌成碱溶液没有固体即可，在这个过程当中一定要注意避免将氢氧化钾弄到皮肤上，因为碱性物质对于我们人体的皮肤是有很强的腐蚀作用的。

1. We first need to pour alkaline substances into water, and then stir them into an alkaline solution. There is no solid. In this process, we must pay attention to avoid getting potassium hydroxide on the skin, because alkaline substances have a strong corrosive effect on our human skin.

2、等到碱溶液的温度在降到了和室内温度差不多的时候，可以往当中添加进去废油差不多再持续的搅拌3~5分钟。

2. When the temperature of the alkali solution is about the same as the indoor temperature, the waste oil can be added and stirred for 3 ~ 5 minutes.

3、接下来需要倒入到模具中即可，在选择模具的时候一定要选择合适材料的，差不多3-5的时间即可凝固不过像是我们自己制作的，需要等到在凝结之后再风干半个月的时候才可以进行使用。

3. Next, you need to pour it into the mold. When selecting the mold, you must select the appropriate material. It can solidify in about 3-5 times. However, it is made by ourselves. It can be used only when it is air dried for half a month after solidification.

4、在制作的过程当中如果想要添加一些有颜色、香味等，也是可以根据相应的配方往当中添加色素或者是香精。

4, in the process of production, if you want to add some colors and fragrances, you can add pigment or essence according to the corresponding formula.

5、不过在添加一下物质的时候一定要注意控制好各种的计量，尤其是往当中添加的碱性物质剂量是一定要控制好的。

5. However, when adding substances, we must pay attention to controlling the measurement of various substances, especially the dose of alkaline substances added to them.
