在化妝品的生產中，水、生產設備、原料和包裝都有可能帶入金屬離子。EDTA二鈉在化妝品中重要的功能就是螯合金屬離子，在溶液中鉗住金屬離子不放，使其很難發生正常的價態反應，從而維護了產品的穩定性，減少了有害金屬離子對皮膚的傷害。下面就讓氫氧化鉀廠家為您講講更多內容吧！

In the production of cosmetics, metal ions may be introduced into water, production equipment, raw materials and packaging. The important function of disodium EDTA in cosmetics is to chelate metal ions. The metal ions are clamped in the solution, making it difficult to have normal valence reaction, thus maintaining the stability of the product and reducing the harm of harmful metal ions to the skin. Now let the potassium hydroxide manufacturer tell you more!

EDTA二鈉還有防腐增效作用，但是EDTA二鈉的譜是不完整和有缺陷的，比如她對革蘭氏陰性菌有較好的能力，特別是對綠膿假單胞菌，在低250ppm時就可以殺滅99.9%，但對革蘭氏陽性菌就沒此效果。所以也限制了他成為防腐劑單獨使用，常常和其他防腐劑一起聯合增效。

EDTA disodium also has antiseptic and synergistic effects, but its bacteriostatic spectrum is incomplete and defective. For example, it has good bacteriostatic ability against gram-negative bacteria, especially against pseudomonas aeruginosa, which can kill 99.9% at 250 ppm, but has no such effect on gram-positive bacteria. Therefore, it also limits its use as a preservative alone, and often works together with other preservatives to enhance efficiency.

當然也有人指出EDTA二鈉存在一定的刺激和過敏問題。但我們注意到，EDTA二鈉在眼藥水中也有應用。可見她的刺激性在一定的添加量下并不強烈。

Of course, some people pointed out that EDTA disodium has certain irritation and allergy problems. However, we have noticed that EDTA disodium can also be used in eye drops. It can be seen that her irritation is not strong at a certain amount.

另外由于她的防腐增效作用，也可以降低一些常規防腐劑的使用量，從這個角度來說，又降低了常規防腐劑的刺激和過敏問題。所以，添加EDTA二鈉的產品，是不是會更刺激仍舊不是很一定的。

In addition, because of its antiseptic and synergistic effect, it can also reduce the use of some conventional preservatives. From this perspective, it also reduces the irritation and allergy problems of conventional preservatives. Therefore, it is still uncertain whether the products added with disodium EDTA will be more stimulating.

當然為了穩妥起見，我們也可以用其他的螯合劑替代EDTA二鈉，比如辛酰羥肟酸，植酸鈉等。但新的螯合劑，就如同新的防腐劑一樣，同樣需要摸索實踐，用時間和更多的數據來證實這種替代是不是更有價值。

Of course, for the sake of safety, we can also use other chelating agents to replace EDTA disodium, such as octyl hydroxamic acid, sodium phytate, etc. However, new chelating agents, just like new preservatives, also need to explore and practice, and use time and more data to confirm whether this alternative is more valuable.

化妝品中的EDTA二鈉，雖然不是都是好處，但她在化妝品中也算功不可沒，對于含肽，或者植物提取物較多的體系，即使不使用EDTA二鈉也好使用其他的螯合劑。作為化妝品使用歷史悠久且廣泛的EDTA二鈉，合理的添加劑量下不需要太過擔憂她的性。更多相關內容就來我們網站http://www.shrisa.cn咨詢了解吧！

Disodium EDTA in cosmetics is not all good, but it also contributes a lot in cosmetics. For systems containing peptides or more plant extracts, it is better to use other chelating agents even if disodium EDTA is not used. EDTA disodium, which has a long history and is widely used as cosmetics, does not need to worry too much about its safety at a reasonable dosage.
