Description and Uses
Diazolidinyl urea was first introduced in 1982 (Sutton Labs, Chatham, New Jersey). It is a colorless, odorless, stable, and water-soluble preservative. It is reported to have a wider antimicrobial spectrum than imidazolidinyl urea, which is structurally related. It is effective against gram-negative and gram-positive bacteria, molds, and yeast but has limited activity against fungi. Diazolidinyl urea, a formaldehyde re1easer, is mainly contained in cosmetics and toiletries, and can be found in barrier creams.
2,5-Diazolidinylurea is a preservative used in cosmetic creams, lotions, shampoos, hair gels, etc.
