目前并未发现EDTA二钠被列为禁用或限用物质。虽然没有限量，但EDTA二钠通常在化妆品中的添加量为0.05-0.2%。而且化妆品不同于食品，根据化妆品的使用特性，每次微量的使用，在皮肤强大的屏障功能之下，吸收量甚微。下面氢氧化钾厂家就来详细讲讲EDTA二钠在化妆品中的利与弊吧。

At present, it is not found that disodium EDTA is listed as prohibited or restricted substance. Although there is no limit, the amount of EDTA disodium in cosmetics is usually 0.05-0.2%. Moreover, cosmetics are different from food. According to the use characteristics of cosmetics, each small amount of use has little absorption under the strong barrier function of the skin. Now let's talk about the advantages and disadvantages of disodium EDTA in cosmetics in detail.

在化妆品的生产中，水、生产设备、原料和包装都有可能带入金属离子。EDTA二钠在化妆品中重要的功能就是螯合金属离子，她在溶液中像螃蟹一样钳住金属离子不放，使其很难发生正常的价态反应，从而维护了产品的稳定性，减少了有害金属离子对皮肤的伤害。

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. She holds the metal ions like a crab in the solution, making it difficult for them to have normal valence reaction, thus maintaining the stability of the product and reducing the harm of harmful metal ions to the skin.

另外她还有防腐增效作用，但是EDTA二钠的谱是不完整和有缺陷的，比如她对革兰氏阴性菌有较好的能力，特别是对绿脓假单胞菌，在低250ppm时就可以杀灭99.9%，但对革兰氏阳性菌就没此效果。所以也限制了他成为防腐剂单独使用，常常和其他防腐剂一起联合增效。

In addition, she has antiseptic and synergistic effects, but the antibacterial spectrum of EDTA disodium is incomplete and defective. For example, she has good antibacterial 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.

当然也有人指出EDTA二钠存在一定的刺激和过敏问题。但我们注意到，EDTA二钠在眼药水中也有应用。可见她的刺激性在一定的添加量下并不强烈。

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，也可以降低一些常规防腐剂的使用量，从这个角度来说，又降低了常规防腐剂的刺激和过敏问题。所以，添加EDTA二钠的产品，是不是会更刺激仍旧不是非常明确的。

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 unclear whether the products added with disodium EDTA will be more stimulating.

当然为了稳妥起见，我们也可以用其他的螯合剂替代EDTA二钠，比如辛酰羟肟酸，植酸钠等。但新的螯合剂，就如同新的防腐剂一样，同样需要摸索实践，用时间和更多的数据来证实这种替代是不是更有价值。

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.

总之，化妆品中的EDTA二钠，虽然不那么美好，但她在化妆品中也算功不可没，对于含肽，或者植物提取物较多的体系，即使不使用EDTA二钠也好使用其他的螯合剂。作为化妆品使用历史悠久且广泛的EDTA二钠，合理的添加剂量下不需要太过担忧她的性。更多相关产品的认识就来我们网站http://www.jinhao360.com咨询了解吧。

In a word, although disodium EDTA in cosmetics is not so beautiful, it has also made great contributions 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.
