Is it really safe to add disodium EDTA to skin care products?

Nowadays, more and more people begin to pay attention to skin care, and the safety of ingredients in various skin care products has become a hot topic. The online world brings bombarded information, and no one knows whether it is true or false, so many people cannot identify the authenticity of cosmetic ingredient information at all.

Recently, some people have found that disodium EDTA is added to many detergents or skin care products, but they don't know what it is? In fact, disodium EDTA was widely used in the early days by adding it to vacuum blood collection tubes as a blood anticoagulant. The mechanism of action is that it is an excellent chelating agent, which can chelate calcium ions in the blood. Later, it was gradually discovered that it can be used in cosmetics and added in an appropriate amount, which is non-toxic and harmless.

As a chelating agent, disodium EDTA can combine heavy metal ions in water or solution. When these heavy metal ions are gathered by disodium EDTA, they will no longer affect the skin. Moreover, sometimes a skin care product is opened and exposed to the air for a long time, and the metal ions will increase, causing oxidation and denaturation reactions. There is no change in the color, smell, texture or cleaning power of the product.

Seeing this, some people will ask is disodium EDTA really safe? In fact, this is inseparable from the dosage. The additive dosage of any substance is clearly required, and the same is true for disodium EDTA. The general dosage is between 0.02% and 0.1%. In addition, many people will question the online saying that disodium EDTA can promote the penetration of other ingredients, but this is not the case. It combines with heavy metal ions in water or solution, but does not affect the skin's absorption of other ingredients.

However, it should be noted that disodium EDTA cannot be taken orally. Oral administration will cause reproductive and developmental effects, and skin contact will not be affected when added to cosmetics. Here, some people may wonder Why is the same thing poisonous after eating, but it's fine if you put it on your face?This is actually because the substances that are effective for the skin are not good for the digestive tract. For example, maintaining skin health tends to have a weakly acidic pH value, while the pH of gastric juice in the digestive tract is about 2. Normal skin is decomposed under strong alkaline conditions, but the digestive tract needs alkaline food to neutralize the acid.
