Description
Technical Field
The present invention relates to a liquid skin cleanser composition.
Background
Conventionally, liquid skin cleansing compositions such as hand soap and body soap have been expected to have good foam properties such as long-lasting foam, and good use feeling such as smoothness of skin during washing, elasticity of skin after being rubbed with a towel, and no feeling of tightness of skin after being rubbed with a towel. However, when using a foam-jet bath foam, which has been increasingly demanded in recent years, as a cleaning tool for cleaning a consumer who uses a cleaning tool such as a nylon towel or a cotton towel, there is a problem that the durability of foam and the low-temperature stability cannot be satisfied at the same time.
In order to impart a good feel in use, for example, a liquid skin cleansing composition containing a fatty acid salt and a cationic polymer derived from a structural unit of dimethyldiallylammonium chloride has been proposed (for example, see patent documents 1 and 2). However, the liquid skin cleansing composition proposed above has problems such as unsatisfactory foam durability when foaming with a cleansing implement such as nylon towel or cotton towel, elasticity of the skin after wiping with towel, and low-temperature stability.
In order to improve the foam persistence of the liquid skin cleansing composition, for example, a liquid skin cleansing composition containing a nonionic surfactant such as polyoxyethylene alkyl ether or fatty acid monoethanolamide has been proposed (for example, see patent document 3). However, the liquid skin cleansing composition of the above proposal has a problem that the elasticity and low-temperature stability of the skin after the towel drying are unsatisfactory.
In general, it is known that long-chain fatty acids such as palmitic acid and stearic acid are added in an increased amount in order to improve the foam durability of a liquid skin cleansing composition, but when the ratio of long-chain fatty acids in a liquid skin cleansing composition is increased, fatty acids are precipitated at low temperatures, and the transparent appearance cannot be maintained, and there are problems such as reduced elasticity of the skin after the skin cleansing composition is rubbed with a towel.
Accordingly, there is a strong demand for a liquid skin cleansing composition filled in a foaming container which has excellent foam durability when foamed with a cleansing implement such as nylon towel or cotton towel, does not feel tight after wiping with towel, has good smoothness of skin at rinsing, has good skin elasticity after wiping with towel, and can prevent precipitation of fatty acid even under low temperature conditions, and maintains a transparent appearance.
