Description

Technical Field

[0001] The present invention relates to a transparent oily cleanser, and more particularly to a transparent oily cleanser for removing makeup. Background Art

[0002] The main purpose of cleansing agents for makeup removal is to remove makeup such as mascara, eye shadow, lipstick, foundation, etc. Such cleansing agents are mostly used to remove makeup while washing the face in the shower. However, when conventional cleansing agents for makeup removal are used in the bathroom with wet hands or face, water is mixed in and the emulsified product is formed, which sometimes becomes cloudy and deteriorates the appearance, or the cleaning effect is greatly reduced due to emulsification.

[0003] In order to solve the above problems, cleaning agents whose cleaning effect is not reduced even when used with wet hands have been proposed. For example, Patent Document 1 proposes a transparent cleaning agent comprising (A) ester oil, (B) aliphatic hydrocarbon, and (C) a nonionic surfactant, wherein the component (C) comprises (C1) C8 to C 10 A polyglycerol difatty acid ester composed of a fatty acid and polyglycerol having an average degree of polymerization of 4 to 10, and (C2)C 18 ~C 22 The polyglycerol difatty acid ester is composed of fatty acid and polyglycerol with an average polymerization degree of 8 to 15, and the mass ratio of component (C1) to component (C2) is 2.5:1 to 10:1. However, for this cleaning agent, it is required to further improve the properties of cleaning effect and rinsing effect.
