Description

  The present invention relates to a cleaning composition.

  The method of making the skin look healthy is roughly divided into a method of making it look beautiful externally by applying cosmetics, and a method of improving the skin quality itself to make it appear healthy (skin color improvement). Of these, massage is generally performed as one method for improving the skin quality itself. Massage is considered to remove the stratum corneum of aged skin by applying physical force from the outside to the skin, improve blood circulation, and improve skin quality. Massage agents have been developed for the purpose of facilitating this massage.

  On the other hand, various studies have been made on skin cleansing agents such as facial cleansers and body soaps in order to obtain good foaming, a high cleaning effect, and a moist feeling after rinsing. In particular, skin cleansing agents such as body soaps are expected to have a high foam volume and fine foam quality during the cleaning process. For this reason, a combination of surfactants with high foaming properties and skin cleansing agents that require high foaming properties in the cleaning process have been studied, and the liquid viscosity of the cleaning agent in combination with general-purpose cationic polymers and nonionic polymers. The development of detergents that increase the amount of foam, make it difficult to disappear, and increase the amount of foam.

  For example, Patent Document 1 describes a skin cleansing composition comprising a combination of a detersive surfactant, cationized cellulose, a dialkyldiallyl quaternary ammonium salt / acrylamide copolymer. Patent Document 2 contains an anionic surfactant, a natural polymer, and a polymer dispersant, maintains an appropriate viscosity even when diluted with water three times or more, and has good liquid stability over time. Concentrated liquid detergent compositions are described. Patent Document 3 describes a detergent composition containing a surfactant and polymer fine particles as having a high effective feeling of foam performance in accordance with the user's sense.
