The component composed of inactive liquid, acid or base is not easy to dissolve and is not fixed, so during the storage process, the inactive liquid does not contact with the acid or base which is not easy to dissolve and is not fixed, but during the use process, The non active liquid contacts the acid or substrate which is not easy to dissolve and is not fixed, so as to change the pH value of the liquid, so as to activate the liquid to provide profits； at the same time, there are alternative variants and methods and components for designing, processing and using compounds. Requirement 1: components of oral care, skin care or home care,Features include: the first component contains an acid or substrate that is not easy to dissolve and is fixed, such as a solid particle or matrix containing an acid or substrate that is not easy to dissolve, the second component, one or more additional components, each component containing an inactive, optional, different liquid Inactive liquid: in the process of storage, the inactive liquid does not contact with the acid or base that is not easy to dissolve and fix, but in the process of use, the inactive liquid contacts with the acid or base that is not easy to dissolve and fix,This changes the pH of the liquid. Claim 2: according to the composition of claim 1, it is characterized by a change in the pH value of the liquid by providing one or more of the following benefits: an increase in the supply of mineral ions, such as fluorination, In a complex composed of basic amino acids and mineral ions, tooth deposition is increased, enzyme matrix activity or reaction is enhanced, bleaching agent activity is enhanced, pH value is more applicable to skin or mouth, color change, anesthetic, taste change,Or change perfume. 13. Claim 3: composition conforming to claim 1 or claim 2, characterized by the fact that the inactive liquid (s) is an oral acceptable mouthwash. Claim 4: constructed in accordance with any prior requirements, characterize
