Inventors include Yamaguchi Kenta; Iwabu Kazuhiro; Iida Takashi; Anzai Toshiyuki; and Iigusa Hitoshi.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: The present invention provides: a detergent composition which has high detergency in the cleaning of a component or the like to which dirt such as a metal working oil adheres, has less harmful properties and fire risk of a detergent, and is excellent in terms of recyclability by a means other than distillation; and a power-saving recycling system in which the detergent composition is recycled by a means other than distillation. The recycling system for a detergent composition includes: a step (1) for cleaning an object to be cleaned by dispersing a solvent component for a detergent composition in water while maintaining the detergent composition at a temperature that is equal to or higher than the cloud point, wherein the detergent composition contains a poorly water-soluble solvent, and has a water content within the range of not less than 60 vol% but less than 90 vol% and a cloud point of 20°C to 70°C; a step (2) for cooling the detergent composition after cleaning to the cloud point or lower, thereby phase-separating dirt from the detergent composition; a step (3) for removing the dirt phase-separated from the detergent composition by a separation means other than distillation; and a step (4) for reusing the detergent composition, from which dirt has been removed, in the step (1) for a non-cleaned object.
