DMDM hydantoin is also an antimicrobial agent used in cosmetics and personal care products. As an antimicrobial, it can help prevent the growth of fungi, yeast and harmful bacteria that can make people sick or give them rashes, for example. DMDM hydantoin is a “formaldehyde donor,” which means that to work as a preservative and antimicrobial, it releases small levels of formaldehyde throughout the shelf-life of a personal care product or cosmetic product.

Erythorbic acid, an epimer of L-ascorbic acid, is used in the United States as a food additive. It was studied, that erythorbic acid enhanced of iron absorption and could play a major role in enhancing iron bioavailability from mixed diets that include foods preserved with erythorbic acid. In addition, was investigated if the erythorbic acid could influence on the metabolism of vitamin C in young women, and obtained results showed, that prolonged ingestion of erythorbic acid had no effect on vitamin C uptake or clearance from the body.
