Description

Cleansing cosmetics

The present invention relates to a cleansing cosmetic suitable for an application for removing oily dirt. This application claims the priority of Japanese Patent Application No. 2018-069675 for which it applied to Japan on March 30, 2018, and uses the content here.

As a cleansing cosmetic used to remove oily dirt on the skin, such as dirt from sebum and makeup cosmetics (= make-up dirt), quickly adjust to sebum and makeup dirt, and rinse clean with water. The thing which can be washed away is calculated | required and the liquid cleansing cosmetics containing an oil agent and surfactant are used preferably (patent document 1). However, liquid cleansing cosmetics, especially when filled in a pump-type container, scatter when discharging, dripping from between fingers when picked up, or dripping from the discharge port of the container. It was a problem to contaminate the container.

International Publication No. 2013/172187

As a method for solving the above problem, a method of adding a thickener to moderately thicken the oil can be considered. However, conventional thickeners (for example, the polystyrene-hydrogenated polyisoprene block copolymer described in JP-A-8-59765) have a viscosity that is too high, so that it can be discharged from a pump-type container or applied to the skin. It was found that the spreadability during application deteriorates. JP-A-2009-155592 discloses 1,2,3-propanetricarboxylic acid tris (2-methylcyclohexylamide) as a gelling agent (thickening agent) for hydrophilic or lipophilic compounds. However, it was found that this compound is difficult to dissolve in an oil and it is difficult to use it as a thickener for the oil. That is, it turned out that it is difficult to use it for cleansing cosmetics with an oil agent with the conventionally well-known thickener (gelling agent).

Accordingly, an object of the present invention is a cleansing cosmetic that is excellent in detergency of oily stains and can be washed away with water by using a thickener added to the oil agent. An object of the present invention is to provide a cleansing cosmetic that is difficult to fall off, has excellent spreadability, and is particularly excellent in dischargeability when filled in a pump-type container.

As a result of intensive studies to solve the above problems, the present inventors have found that a compound having a specific structure can increase the viscosity of an oil agent to an arbitrary viscosity and maintain the viscosity stably. Cleansing cosmetics that contain moderately thickened oils and surfactants have excellent cleaning performance for oily stains, can be washed away with water, and have excellent discharge properties when filled in pump-type containers. It has been found that when applied to the skin, it is difficult to sag when it is taken, and it is difficult to spill liquid from the outlet of the container. The present invention has been completed based on these findings.

It can be blended and then washed off with water to remove it cleanly. Further, when filling a pump-type container, it can be discharged without being scattered, and dripping from the discharge port can be suppressed. Therefore, the cleansing cosmetic composition of the present invention is particularly suitable as a cleansing cosmetic composition for oily soil that is used by filling a pump-type container.

The cleansing cosmetic composition of the present invention can be produced, for example, through a step of making the thickener (A) and the oil agent (B) compatible. More specifically, the total amount of the thickener (A) and the oil agent (B) is mixed and heated, and after being dissolved, cooled, further cooled, and then added with the surfactant (C). Can be manufactured. Further, the thickener (A) may be mixed with a part of the oil agent (B), heated and compatible, then cooled, and then mixed with the remaining oil agent (B). it can.
