Uses
Dimethyloldimethyl hydantoin is a popular preservative with moderate sensitizing potential, it is used to control against mold, mildew, and bacterial spoilage. This preservative is similar to imidazolidinyl urea, as both act by releasing formaldehyde into the formulation. Cosmetic expert panels have determined that Dimethyloldimethyl hydantoin has an excellent safety record for use in both leave-on and washoff cosmetic preparations. Maximum-use concentrations are set at 0.2 percent in the u.S. and 0.6 percent in the european union. Dimethyloldimethyl hydantoin stands for dimethylimidazolidine, though in a listing the acronym is rarely spelled out.

Flammability and Explosibility
Non flammable
Synthesis
A method for the preparation of an antifreeze DMDM glycolide urea,
A 2L three-necked round-bottomed flask was assembled with a stirrer, and a temperature regulator. 600g of formaldehyde was placed in the flask and the pH was adjusted to 7.4 with aqueous sodium hydroxide solution. 500g of hydantoin was added to the flask, intense exotherm was observed, the temperature increased and most of the hydantoin was dissolved. The pH was adjusted to 8.3 with aqueous sodium hydroxide solution and the reaction mixture was continued to be stirred at 55C for 1 hr. 175 g of water was added and then cooled to room temperature. 10.5 g of NH4Cl was added and stirred well. The pH was adjusted to 7.0. the above product is the antifreeze DMDM acetonitrile.
