Description

[0001] Composition for oil-based liquid cleansing [

The present invention relates to a composition for oily liquid cleansing.

For the purpose of cleansing skin contamination or make-up cosmetics, oily cleansing agents are commercially available. This has been developed primarily for the purpose of exerting a cleansing effect, and many liquid ones have been developed. Conventional oily cleansing agents have disadvantages in that their cleansing power is markedly lowered because they become opalescent as emulsions or suspensions when used in wet skin. In recent years, however, a composition for oily liquid cleansing that does not emulsify or significantly thicken even when a significant amount of water is mixed has been developed, and has been commercially available as a product that can be used in a wet environment such as a bathroom or wash basin.

The liquid oily cleansing composition having the above function is designed so that water can be blended in advance or that a large amount of water can be solubilized, and all the pharmaceuticals as a formulation have low viscosity. A composition for oily liquid cleansing having a low viscosity has a problem that it is difficult to shake off hands and that it flows down from the fingers, and it is difficult to apply it as a target portion at the time of use (Japanese Patent Laid-Open No. 2004-75566). Further, since the composition for oily liquid cleansing having a low viscosity is difficult to leave in the coated portion during cleansing, the skin rubs directly on the skin, leading to irritation to the skin and discomfort during use.

As a technique for thickening a composition for oily liquid cleansing, there has been disclosed a technique of thickening using (behenic acid / eicosanic acid) glyceryl to prevent it from flowing down from the finger during use (see Patent Document 2 2003-267835).

A composition for oil-based liquid cleansing which maintains cleansing properties in a wet environment with hands or a face, comprising: a solvent-in-water emulsion containing at least 50 mass% of a liquid at room temperature in a liquid state and 20 to 40 mass% of a nonionic surfactant having an HLB of 5 to 16 A composition for cleansing (Patent Document 3: Japanese Unexamined Patent Application Publication No. 2006-225458), a composition for oily liquid cleansing containing a monoglycerin fatty acid ester, a polyglycerin fatty acid ester and a nonionic surfactant, and a liquid oil and water at 25 占 폚 (Patent Document 4: JP-A-2004-75566).

The applicant of the present invention first proposed an oil-based cleansing method which can be used in an environment in which hands and face such as a bathroom or a sink are not used, (Patent Document 5: Japanese Patent No. 3729836).

However, as a response to make-up cosmetics with improved durability these days, problems of thickening and separation have arisen in the process of compounding the emulsions having excellent cleansing powers in prescription.
