Bisurea gelling agents that impart a number of unexpected benefits within various gelled formulations and exhibit great versatility in terms of gelling capabilities for many types of solvents are provided. Such gelling agents should include pendant groups, such as sterically hindering alkyl groups attached to polyoxyalkylenated moieties that allow the gelling agent to be compatible with the target liquid system at elevated temperatures, while controlling and/or limiting the network formation and strength during the cooling cycle. Alternatively, novel gelling agents having two urea groups but that are asymmetrical in configuration have been produced in order to provide the same control in temperature, compatibility, and efficiency. Final gelled formulations, such as antiperspirant sticks and other like consumer items, are provided as well within this invention.
