Abstract

Urea mixtures and methods for making and using same are provided. In at least one specific embodiment, the urea mixture can include urea, a urea-aldehyde resin, a liquid medium, and a sugar. The urea mixture can have an aldehyde to urea molar ratio of about 0.2:1 to about 0.7:1. The urea mixture can have a sugar concentration of about 2 wt % to about 8 wt %, based on the combined weight of the urea, the urea-aldehyde resin, the liquid medium, and the sugar.
