The difference between EDTA disodium blood vessel grade and cosmetic grade

Product Details

EDTA disodium, also known as ethylenediaminetetraacetic acid disodium, or EDTA 2Na, is a solid white powder at room temperature and pressure. Its chemical properties are characterized by its ability to chelate with almost all metal ions. Its application fields are very extensive, and its footprints can be found in fields such as chemical experiments, food, daily chemistry, and medical treatment. Although all EDTA disodium is used, the level and purity used in different fields are different. Below will be an introduction to EDTA disodium at the blood collection vessel level and EDTA disodium at the cosmetic level.

1. Cosmetic grade EDTA disodium

The EDTA disodium used in cosmetics belongs to the industrial grade, and due to its small dosage and being used outside the skin, it is not required to be as high as the blood collection grade. When the presence of metal ions in cosmetics can have practical or potential adverse effects on the cosmetic formula system, it is necessary to add disodium EDTA to chelate the metal ions inside and maintain the safety of the cosmetic formula.

2. EDTA Disodium at the Blood Sampling Level

The EDTA disodium used in blood collection is of analytical purity level, as it is mainly used for blood analysis in the human body, there are requirements for purity and level. The main function of EDTA disodium is to have an in vitro anticoagulant effect on the blood, and its principle is also related to its chemical properties. It can chelate Ca2+in the blood, prevent blood coagulation, and prolong the original characteristics of blood samples for blood testing and analysis. It is worth noting that this anticoagulant effect is not irreversible and requires testing to be completed within a certain period of time.
