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. The result is that a reliable, hard gel is formed that does not crash out of solution easily and that does not exhibit unwanted cracking or precipitating out within the final formulation. 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.
本文提供了一种Bisurea凝胶剂,它在各种凝胶配方中带来了许多意想不到的好处,并且在凝胶能力方面表现出极大的多样性,适用于许多类型的溶剂。这种凝胶剂应包括挂链基团,例如附加到聚氧烷基化物上的空间阻碍烷基基团,使凝胶剂在升高的温度下与目标液体系统兼容,同时在冷却周期中控制和/或限制网络形成和强度。结果是形成了可靠的坚硬凝胶,不易从溶液中崩解,不会在最终配方中出现不必要的开裂或沉淀。另外,为了提供相同的温度、兼容性和效率控制,还制备了具有两个
脲基但配置不对称的新型凝胶剂。本发明还提供了最终的凝胶配方,例如止汗膏和其他类似的消费品。
