Described herein are compositions comprising an unactivated liquid, an immobilized sparingly soluble acid or base, such that during storage the unactivated liquid is not in contact with the immobilized sparingly soluble acid or base, but upon use, the unactivated liquid contacts the immobilized sparingly soluble acid or base, whereby the pH of the liquid is altered, thereby activating the liquid to provide a benefit； together with variant and alternative designs, methods of making and using the compositions, and components thereof.本發明係關於包含未活化液體、固定化難溶性酸或鹼之組成物，如此於儲存的時候，該未活化液體不與該固定化難溶性酸或鹼接觸，但於使用時，該未活化液體接觸該固定化難溶性酸或鹼藉以改變該液體之pH，因而活化該液體而提供利益；以及變化及替代設計，製造及使用該組成物及其組份之方法。
