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!

氫氧化鉀主要在化妝品中起調(diào)節(jié)酸堿度的作用。一般可以在洗發(fā)水軟皂、臟皂、冷霜、雪花膏、洗發(fā)水等化妝品成分表中看到。

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.
           

當(dāng)氫氧化鉀加入到面霜中，它會參與到油和水的乳化過程中，被視為乳化過程中的催化劑。加入適量的堿可以與基礎(chǔ)油中的酸性成分反應(yīng)生成親水性表面活性物質(zhì)，從而使基礎(chǔ)油乳化形成水包油乳液，提高了乳化效果和穩(wěn)定性，使乳膏更加細(xì)膩、穩(wěn)定、不易變質(zhì)。

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.

氫氧化鉀腐蝕性很強(qiáng)，但在化妝品中的用量很小，主要用于調(diào)節(jié)pH值，尤其是它是皂基洗面奶產(chǎn)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.

本期的內(nèi)容就簡單的介紹到這里了，只要化妝品中的氫氧化鉀符合添加劑用量的要求，就不用擔(dān)心傷害皮膚。

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.
