2. Description of the Related Art Cleansing cosmetics are used as cosmetics in which oil components are applied to the skin for the purpose of removing dirt and makeup cosmetics from the skin or for the purpose of massaging the skin.
There are massage cosmetics. These are to be applied to the skin and then removed from the skin after fulfilling its intended purpose. Such cosmetics are commercially available in the form of oil, cream of oil-in-water type or water-in-oil emulsion, or gel of surfactant-in-oil emulsion.

However, these conventional cleansing cosmetics and massage cosmetics containing an oil component have drawbacks such as stickiness during use and poor storage stability.

Recently, cleansing cosmetics, massage cosmetics and the like utilizing a liquid crystal structure comprising a hydrophilic nonionic surfactant have been reported as techniques for solving these disadvantages (Japanese Patent Publication No. 53845/1993). No.).

However, cosmetics using these liquid crystal structures have a high viscosity at the beginning of spreading when they are applied to the skin or massaged, and the liquid crystal structures are difficult to break, so that the oil agent does not seep out. The problem is that it is slow, particularly slow to get used to stains that are difficult to remove, and stains remain.
