JP6062279B2 - Liquid detergent composition - Google Patents

Description

The present invention relates to a liquid detergent composition filled in a non-gas type foam discharge container. More specifically, the present invention relates to a liquid detergent composition that is free of clogging, provides a creamy and stable foam, is excellent in foam formation even at low temperatures, and has a refreshing feeling during rinsing and a moist feeling after towel drying.

Various liquid detergent compositions that are filled in a non-gas type foam discharge container and discharged from the container in the form of foam during use have been proposed (see, for example, Patent Documents 1 to 5). Such a liquid detergent composition is made to foam by mixing the composition and air by passing the porous film inside the foam discharge container. However, while foam formation with excellent foam quality (foam creaminess, foam fineness, etc.) is possible, it is necessary to pass through the porous membrane, so the composition causes clogging in the porous membrane. There is a problem. In particular, when fatty acid soap is used as a surfactant, there is a problem that clogging is likely to occur due to precipitation of higher fatty acids during low-temperature storage. Furthermore, in recent years, consumer demands for usability and the like have tended to increase compared to the past, and further improvements in foam quality, improved feeling after washing, prevention of clogging, etc. There is a need for improved technology.
