A method for preparing low free formaldehyde methylol-hydantoins and compositions thereof |
| abstract |
Compositions of dimethyloldimethylhydantoin, monomethyloldimethylhydantoin, and dimethylhydantoin having less than 0.1% by weight of free formaldehyde based upon 100% by weight of total composition; and wherein the weight ratio of dimethyloldimethylhydantoin to monomethyloldimethylhydantoin ranges from about 1:1.25 to about 3.5:1, are provided. These compositions may be prepared (1) by reacting dimethylhydantoin and a formaldehyde-containing source wherein the molar ratio of formaldehyde to dimethylhydantoin ranges from about 1.2:1 to about 1.55:1 or (2) by admixing (a) from about 80 to about 90% by weight of an aqueous solution of methyloldimethylhydantoin having greater than about 0.1% by weight of free formaldehyde with (b) about 20 to about 10% by weight of dimethylhydantoin based upon 100% weight of aqueous dimethyloldimethylhydantoin solution and dimethylhydantoin combined. |
