Description

  The present invention relates to a cleaning composition.

  Conventionally, 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, surfactants with high foaming properties are combined together to increase the liquid viscosity of the cleaning agents in combination with skin cleansing agents that require high foaming properties in the cleaning process, general-purpose cationic polymers, and nonionic polymers. The development of detergents that make it difficult to eliminate bubbles and increase the amount of bubbles is underway.

  For example, Patent Documents 1 and 2 describe a detergent composition containing an anionic surfactant and a glyceryl ether having an alkyl group having 4 to 12 carbon atoms. Patent Document 3 discusses a skin cleansing composition comprising a combination of a detersive surfactant and cationized cellulose.
