Application of disodium EDTA in cosmetics

Details:

I wonder if you have noticed that disodium EDTA is often seen in many big brand washing and care products we use every day, but I don't know its role. In fact, disodium EDTA can be used as a stabilizer, coagulant, antioxidant and preservative, and can play the role of color protection, oxidation resistance, corrosion prevention and stability. What role does it play in cosmetics Let's go on.

Disodium EDTA (ethylenediamine tetraacetic acid) is a water-soluble acid and an emulsion stable preservative with chelating properties. It works by binding with metal ions in solution, making them inactive. In skin care products, this helps prevent cosmetic formula and other personal care products such as lotions and creams from spoiling. In general, disodium can protect the integrity of skin products and prevent unnecessary consistency changes, pH changes, odor changes or texture changes. Helps prevent the growth of bacteria, yeasts and molds in skin care products. Although preservatives usually have a bad reputation in the skin care industry, they help extend the shelf life of products and prevent bacterial contamination. Moreover, the skin irritation of disodium synthetic preservatives is lower than that of some natural preservatives, and it is not easy to have adverse reactions with other ingredients in cosmetics. In addition, when combined with calcium, iron or magnesium, EDTA two sodium will enhance foam and cleaning ability.

In addition to being used as a preservative in cosmetics, disodium EDTA can also improve the permeability of skin barrier and assist other ingredients to penetrate deeper into the skin, allowing the active ingredients in skin care products to penetrate deeply, so as to produce better skin care effect. Moreover, disodium is a well tolerated ingredient, which is suitable for a wide range of skin types, so it is not easy to cause allergic reactions.
