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 when making them. 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. First of all, we need to pour alkaline substances into water, and then stir it into alkaline solution without solid. In this process, we must pay attention to avoid getting potassium hydroxide on our skin, because alkaline substances have strong corrosive effect on our 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 almost the same as that in the room, waste oil can be added into it, and the stirring can be continued for about 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, we need to pour it into the mold. When choosing the mold, we must choose the right material. It can solidify in about 3-5 minutes, but it's like we made it ourselves. We need to wait until it's condensed and then dried for half a month before we can use it.

　　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 some substances, we must pay attention to control all kinds of measurement, especially the dosage of alkaline substances added to it.

　　上面介绍的就是氢氧化钾大体制造肥皂的一个过程，当我们再制造肥皂的时候一定要注意保护好自己，不过小编其实还是比较建议购买正规公司的肥皂进行使用，因为自己制造的可能添加的碱性物过多或者是过少，导致在进行使用的时候受到一些影响。

　　The above is a general process of making soap with potassium hydroxide. When we make soap again, we must pay attention to protect ourselves. However, Xiaobian still suggests buying soap from regular companies for use, because we may add too much or too little alkali, which will affect our use.
