It’s helpful properties can prevent a number of changes, keeping your beauty potions as consistent and reliable as ever. This ingredient is essential in maintaining the pH balance and texture of beauty products, helping to retain their freshness and smoothness for longer.[2] Without Disodium EDTA, odors might start creeping in faster than they should,[3] so it’s a great ingredient to keep our products smelling fresh and fragrant!
