You often hear that sodium hydroxide is alkaline. Because of its properties, it can be used to make soap. But do you know the steps to make soap with it? Let's talk about it next. I hope it can help you.

1、先將氫氧化鈉倒入水中，攪和成堿溶液（這個(gè)進(jìn)程必定不要讓燒堿弄到肌膚上面，防止損害肌膚）。

1. First, pour sodium hydroxide into the water, mix with the alkaline solution (this process must not let the caustic soda get on the skin to prevent damage to the skin).

2、堿溶液的溫度降到和室內(nèi)溫度相同的時(shí)分，加入廢油，再攪和3~5分鐘。

2. When the temperature of alkali solution drops to the same time as the indoor temperature, add waste oil and mix for 3-5 minutes.

3、倒入模具中（家里經(jīng)常用的，比方塑料盒、首飾盒等），3~5天就能夠凝結(jié)。

3. Pour it into the mold (often used at home, such as plastic box, jewelry box, etc.), and it will coagulate in 3-5 days.

5, if you want to have color or fragrance, you can participate in the pigment, essence.

大家在學(xué)習(xí)了上述關(guān)于氫氧化鈉制造肥皂的進(jìn)程的相關(guān)知識，希望對大家能有所幫助，另外，在使用的時(shí)候一定
