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.

Abstract: A powdery composition comprising the following components (A), (B) and (C). A hair dyeing or bleaching kit composed of a first composition consisting of a powdery composition and a second composition comprising hydrogen peroxide. Component (A): an alkanolamine having an SP value by the Fedors method of 10 (cal/cm3)1/2 or more and 16 (cal/cm3)1/2 or less or a salt thereof; Component (B): a compound having an SP value by the Fedors method within ±6 (cal/cm3)1/2 inclusive of the SP value of the component (A) as an alkanolamine (with a proviso that compounds corresponding to component (A) are excluded from component (B)); Component (C): a powdery carrier.

Abstract: A method of improving smoothness of an item to be washed during washing, including the step of washing the item with a washing liquid under conditions where an organic polymer having spinnability is present in the washing liquid; a process for hand-washing including the step of hand-washing an item to be washed with a washing liquid showing spinnability containing an organic polymer having spinnability, or a washing liquid prepared by diluting the washing liquid with more than 1-fold to 1,000-fold amount of water; a detergent composition containing an organic polymer having spinnability having an average molecular weight of 1,500,000 or more in an amount exceeding 0.1% by weight of the detergent composition; a laundry detergent composition comprising a polymer having an average molecular weight of 500,000 or more, wherein 60% by mole or more of constituting monomers has a sulfonic acid group or a salt form thereof, or a sulfuric acid group or a salt form thereof.
