Disodium EDTA
CAS No. - Mixture


EDTA, Ethylenediaminetetraacetic acid is a molecule which complexes metal ions in aqueous environments. It is available in four neutralizations, two of which, Disodium EDTA and Tetrasodium EDTA, are commonly used in the cosmetics. Generally, the choice of which product to use is determined by the pH of your product, but this is not a hard and fast rule. Disodium EDTA is commonly used in neutral to mildly acidic products, like most creams, lotions, and neutral pH liquid soaps and shampoos. EDTA works synergistically with your preservative to improve preservative efficacy.

Disodium EDTA has limited solubility in water, but at a typical usage rate of 0.2% to improve preservative efficacy, even if not fully solubilized, it is still efficacious.  In creams or lotions, there will be no grittiness and it will not be seen. In clear or transparent gel, serum, or clear surfactant systems, use Tetrasodium EDTA, which is highly soluble in water. At low usage rates, it will not raise the pH unduly, but if it does, you can simply lower the pH of your formulation with a citric acid solution.


Recommended Usage Rate: 0.2%

Our Customers Say...
Thought that I misplaced my soap bevel when I moved and then could not find the web sight of where the purchase originated. Found the bevel and thank goodness I found the receipt of the purchase!!! Wanted to pass on that it is fantastic and easy to use. It bevels two different sizes and I love it.

Wow, I can't say enough about my experiences with this company.
I have been happy with everything I've ordered and their pricing is very competitive but it is the customer service that sets Lotioncrafter apart from other companies.
Orders are processed and shipped quicker than any other company I've ordered from & each time I've received a refund for lower shipping costs before I even noticed!
Any questions I've had were answered right away & even received a phone call to explain things more personally.
Thank you so much for the great work!

Hello this is Barry from mountaincrafted and I ordered Hydrolyzed Silk Protein from this company and what a difference in our products it made! We use it in all of our hair & skin products, but our customers love it most in our goat's milk soap. Try it, it will surely boost your sales!
