The present application provides a composition configured to be provided in a flowable, liquid form but configured to transition to a solid or semi-solid gel based upon a change in pH. The change in pH can arise from one or more materials utilized in the composition itself or based upon encountering an environment with a significantly different pH. The compositions are particularly suited for useas a teat sealant in non-human mammals, particularly cattle. 本申请提供组合物，所述组合物被配置为以可流动液体形式提供，但是被配置为基于pH的变化而转变为固体或半固体凝胶。pH的变化可能由所述组合物本身中所用的一种或多种材料引起，或者是基于遇到具有明显不同pH的环境所引起。所述组合物特别适合于用作非人类哺乳动物，特别是牛中的乳头密封剂。
