Abstract: The present invention relates to the provision of salt-sensitive particles capable of improving the feeling of effects at the time of use of an oil agent to be blended in a cleaner or the like and a method for producing the same, and so on. The present invention provides the following [1] to [4]. [1] Salt-sensitive particles containing an oil agent having a solubility in 100 g of water of less than 1 g and an acid-modified polyvinyl alcohol, wherein the oil agent is dispersed in the salt-sensitive particles. [2] A cleaner containing the salt-sensitive particles as set forth in [1]. [3] A method for cleaning a skin, a hair, or a clothing, including using the cleaner as set forth in [2]. [4] A method for producing the salt-sensitive particles as set forth in [1], including a step of preparing an emulsion composition containing an oil agent having a solubility in 100 g of water of less than 1 g and an acid-modified polyvinyl alcohol; and a step of removing the water from the emulsion composition.
