Description

  The present invention relates to a liquid composition, in particular, a liquid cleansing composition.

  Make-up cosmetics made from eye products such as foundations, lipsticks, eye shadows, eyeliners and mascara around the eyes, as well as their make-up effects, long-lasting and high water resistance, etc. Has come to be required. Therefore, the coating film formed on the skin of these makeup cosmetics has become stronger than before. However, on the other hand, there remains a problem that removal of make-up after use cannot be completely removed in a short time.

  Against this background, cleansing agents mainly composed of detergents that are surfactants and oil cleansing agents mainly composed of oil components and the like have been developed and marketed. However, removal of the makeup takes time, and since the removal is insufficient, the level of safety such as skin irritation is not always satisfactory for consumers.

  As such a cleansing agent, for example, a cleansing agent using a polyglycerin fatty acid ester type surfactant capable of solubilizing a large amount of oil has been developed (for example, Patent Documents 1 to 3). This is a cleansing agent containing a polyglycerin fatty acid ester type surfactant, a polyhydric alcohol, an oil agent and water as basic components. In this way, polyglycerin fatty acid ester type surfactants and polyhydric alcohols containing a large amount of glycerin are used, and many cleansing agents containing an oil agent are currently found in the market. This dosage form has an appropriate viscosity, can improve the familiarity with the makeup cosmetic ingredients, and can also reduce the residual feeling due to the oil after rinsing.

  Furthermore, a cleansing agent containing amphiphilic dilauroyl glutamic acid lysine sodium in order to improve the storage stability of a cleansing agent system comprising polyglycerin fatty acid ester type surfactant, oil agent, polyhydric alcohol and water as constituent components Have also been proposed (for example, Patent Documents 4 and 5).

JP-A-7-96162 JP-A-6-219923 JP 2007-23025 A JP 2008-195665 A JP 2007-186498 A

  These conventional cleansing agents can improve the familiarity with the components of makeup cosmetics, and can also reduce the residual feeling due to the oil after rinsing. However, since these conventional cleansing agents have low storage stability, the water content is about 2%. Therefore, the feeling when using the cleansing agent and the feeling after using the cleansing agent. The problem still remains. For this reason, it is desired to improve the feeling of use when the cleansing agent is picked up and to solve the problem of residual feeling, and to give a refreshing and fresh feel after using the cleansing agent.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a liquid composition that can increase the content of water in a liquid cleansing composition while suppressing a decrease in storage stability, particularly a liquid cleansing composition. .
