Cosmetics will add a variety of ingredients, in addition to effective skin care ingredients, there will be some additives. The role of additives is to ensure that cosmetics maintain skin care effect within the shelf life, so what is the role of potassium hydroxide added to cosmetics? Is it harmful to the skin? If you don't understand this ingredient, please continue to look down together!

氢氧化钾主要在化妆品中起调节酸碱度的作用。一般可以在洗发水软皂、脏皂、冷霜、雪花膏、洗发水等化妆品成分表中看到。

Potassium hydroxide is mainly used to regulate pH in cosmetics. Generally, it can be seen in the list of cosmetic ingredients such as shampoo, soft soap, dirty soap, frost, cream, shampoo, etc.
           

当氢氧化钾加入到面霜中，它会参与到油和水的乳化过程中，被视为乳化过程中的催化剂。加入适量的碱可以与基础油中的酸性成分反应生成亲水性表面活性物质，从而使基础油乳化形成水包油乳液，提高了乳化效果和稳定性，使乳膏更加细腻、稳定、不易变质。

When potassium hydroxide is added to the cream, it will take part in the emulsification process of oil and water. It is regarded as a catalyst in the process of emulsification. Adding appropriate amount of alkali can react with the acidic components in the base oil to form hydrophilic surfactant, so that the base oil is emulsified to form water in oil emulsion, which improves the emulsifying effect and stability, and makes the cream more delicate, stable and not easy to deteriorate.

氢氧化钾腐蚀性很强，但在化妆品中的用量很小，主要用于调节pH值，尤其是它是皂基洗面奶产品中不可缺少的原料。

Potassium hydroxide is highly corrosive, but its dosage in cosmetics is very small. It is mainly used to adjust pH value, especially it is an indispensable raw material in soap based facial cleanser products.

本期的内容就简单的介绍到这里了，只要化妆品中的氢氧化钾符合添加剂用量的要求，就不用担心伤害皮肤。

The content of this issue is simply introduced here. As long as the potassium hydroxide in cosmetics meets the requirements of additive dosage, there is no need to worry about skin injury.
