| titleOfInvention | PROCESS FOR PREPARING AN AQUEOUS SOLUTION OF DIMETHYLOL-DIMETHYLHYDANTOIN AND SOLUTION OBTAINED |
| abstract | The invention relates to a process for preparing an aqueous solution of 1,3-dimethylol-5,5-dimethylhydantoin. The process involves mixing formaldehyde and 5,5-dimethylhydantoin in a ratio of about 1.85 to 2.4 moles of formaldehyde per mole of dimethylhydantoin in water, adjusting the pH with a compatible alkalinizing agent to allow the reaction to be carried out at a pH of at least 7 to about 9 and to react the reactants at a temperature of about 22 to 65 degrees C and a pH of 9 to 7 for a period sufficient for the formation of 1,3-dimethylol-5,5-dimethylhydantoin is substantially complete. The invention also relates to the solution obtained by this process. This solution is useful for use, for example, as a formaldehyde donor and as a preservative additive for various preparations such as pastes, soaps, skin creams, liquid shampoos, etc. |
