Description

Application of Article 30, Paragraph 2 of the Patent Act Announced through telecommunication line Date of publication July 10, 2018 Address of publication http://www. Kracie. co. jp/release/10147405_3833. html

TECHNICAL FIELD The present invention relates to a skin cleanser composition filled in a non-gas type foam discharge container. Specifically, it relates to a skin cleanser composition that does not clog even at low temperatures, provides creamy and stable foam, does not irritate the skin during use, and provides a moist feeling during rinsing and a moist feeling after drying with a towel. .

Various proposals have been made so far for liquid detergent compositions that are filled in a non-gas type foam discharge container and discharged from the container in a foamy state at the time of use (see, for example, Patent Documents 1 to 5). Such a liquid detergent composition is passed through the porous membrane inside the foam discharge container to mix the composition and air into a foamy state. However, while it is possible to form bubbles with excellent foam quality (creaminess of foam, fineness of foam, etc.), it is necessary to pass through the porous membrane, so the composition clogs the porous membrane. There is a problem. In particular, when a fatty acid soap is used as a surfactant, there is a problem that clogging tends to occur due to precipitation of higher fatty acids during low-temperature storage. Furthermore, in recent years, there has been a trend toward higher consumer demand for usability, etc., and further improvements in foam quality, improved usability after washing, prevention of clogging, etc. Improvement of technology is required.
