EDTA is a sequestering and chelating agent used widely in color cosmetics, soaps, shampoos and toiletries to bind trace metals and to prevent color, texture and fragrance changes in the product. EDTA has several industrial and medical uses and it’s sometimes added to soft drinks and other foods.
The only problem with EDTA is its wide usage. It does not biodegrade as easily as some of the newer materials being developed. We have chosen to keep EDTA in our soap base while we investigate other alternatives.
We use EDTA in our soap-base, which helps to stabilize the fragrance, texture and color.
