现在很多人买化妆品都会去查看成分表,而买洗面奶的时候也不例外,但是我们在查看的时候会发现,很多的洗面奶里面会有氢氧化钾,我们大家都知道,这是一种碱性物质,那么在使用的时候不会对皮肤造成伤害可以使用吗,下面我们就来了解一下吧。
Now many people will check the ingredient list when buying cosmetics, and there is no exception when buying facial cleanser. However, when we check, we will find that there will be potassium hydroxide in many facial cleansers. We all know that this is an alkaline substance, so it will not cause damage to the skin when used. Can we use it? Let's learn about it below.
碱是制作清洁用品一定需要的,一般制造洗面奶的时候都需要使用,固态皂时一般都会使用氢氧化钠,因为它们都是碱性物质。碱与油脂在反应之后会转化成皂和甘油,成熟皂的主要成分一般都是脂肪酸盐,这是一种表面活性剂,有亲油端和亲水端。亲油端会吸收皮肤中的过氧化油脂还有污垢,而在冲水的时候亲水端就会与水结合从而带走污垢,这样就起到了清洁的作用。这也就是固体肥皂或洗面奶的清洁原理。

Alkali is necessary for making cleaning products. It is generally used when making facial cleanser. Sodium hydroxide is generally used when making solid soap, because they are alkaline substances. After the reaction between alkali and oil, it will be transformed into soap and glycerol. The main component of mature soap is generally fatty acid salt, which is a surfactant with lipophilic end and hydrophilic end. The lipophilic end will absorb the peroxide oil and dirt in the skin, and when flushing, the hydrophilic end will combine with water to take away the dirt, which plays a cleaning role. This is the cleaning principle of solid soap or facial cleanser.
洗面奶中的氢氧化钾一般都不会对皮肤产生伤害。因为碱性在与油脂混合反应后,就已经不是碱性了。而且可以促使油脂水解,与水解后的酸发生中和反应,而我们在成分表中看见的月桂酸、肉豆蔻酸就是和碱性进行反应的,从而生成脂肪酸钾起到清洁的作用。
Potassium hydroxide in facial cleanser generally does not harm the skin. Because alkaline is not alkaline after mixing with oil. Moreover, it can promote the hydrolysis of oil and neutralize with the hydrolyzed acid, and the lauric acid and myristic acid we see in the composition table react with alkali to produce fatty acid potassium and play a cleaning role.
相信大家看完上面的解释,可以知道含有氢氧化钾的洗面奶是可以使用的,而且其清洁效果也是比较好的,不过在洗完脸之后也需要做好后续的保湿补水的工作
I believe that after reading the above explanation, you can know that the facial cleanser containing potassium hydroxide can be used, and its cleaning effect is also relatively good. However, after washing the face, you also need to do the follow-up moisturizing and moisturizing work
