WHAT ARE THE BENEFITS OF DISODIUM EDTA ?
By stabilizing cosmetic products, disodium EDTA prevents them from deterioration. Moreover, it prevents dramatic changes in the active ingredients in skincare products to prevent them from being ineffective, such as by preventing texture or pH changes. In some cleansers it can improve the foaming effect.
WHAT IS DISODIUM EDTA ?
Disodium EDTA is a water-soluble compound that chelates to stabilize skincare products. As a chelator, it inactivates metal ions in solutions.
IS DISODIUM EDTA SAFE FOR ALL SKIN TYPES AND TONES?
Disodium EDTA is likely safe for all skin types and tones based on available data. However, it is a contact allergen noted in multiple studies. Patients with hypersensitivity to this compound should be cautious when considering use of cosmetic products that may contain it.
CONTRAINDICATIONS
There is minimal data on contraindications for the topical application of agents containing disodium EDTA. Patients with contact dermatitis to cosmetic products may need to consider cessation of products containing disodium EDTA.
