Related application

The present invention is based on the priority claim of Japanese Patent Application: Japanese Patent Application No. 2021-96964 (filed on June 09, 2021), and the entire contents of the application are incorporated herein by reference. shall be

The present disclosure relates to detergent compositions. In particular, the present disclosure relates to an oily detergent composition having an oily component as a main component.

Oil-based detergents such as cleansing oils are suitable for cleaning oil-based cosmetics (see, for example, Patent Document 1).

Patent Document 1 discloses a composition containing (A) a nonionic surfactant having an HLB of 6 to 14, (B) an oily component, and a water content of less than 5% by mass, wherein the composition is mixed with water. An oily cleansing composition is disclosed that forms an aqueous micellar phase or a bicontinuous microemulsion phase when mixed in a 4:6 ratio.

WO2005/079729A1

The following analysis is given in light of this disclosure.

"Oil-based cleansers are generally transparent." Oily cosmetics are often used for cleansing oily makeup. Washing of make-up may be performed in a state where hands are wet, such as in a bathroom, after washing hands, for example, when returning home. However, some oil-based cleansers emulsify when mixed with water adhering to hands. When a transparent oily detergent is emulsified, it becomes cloudy. When the cleanser becomes cloudy, detergency is lowered, and the user feels that the cleanser is denatured. Therefore, an oil-based cosmetic that has a high detergency and does not become cloudy even when applied with wet hands is desired.

In addition, it is desirable that the cleaning composition has a certain degree of viscosity (thickness). Thickness not only makes it easier to pick up, but also allows more of the cleansing agent to adhere to the part to be cleaned (for example, the skin), thereby enhancing cleansing power. In addition, the user can also be given an impression that the cleanser is in close contact with the skin. Furthermore, if the cleansing agent has a thick consistency, the cleansing agent intervenes between the hand and the part to be cleaned when the part to be cleaned is rubbed with the hand, thereby reducing the frictional resistance and reducing the burden on the skin. can be done. In the oil-based cleansing composition described in Patent Document 1, the thickness of the composition may be insufficient.

Therefore, there is a demand for a cleansing composition that does not cause white turbidity even when mixed with water that adheres to the hands during use, and that can cleanse in a thickened state.

According to the first aspect of the present disclosure, it contains (A) 50% to 85% by mass of an oily component and (B) 12% to 45% by mass of a surfactant. (A) The oil component comprises (A1) a liquid first oil component composed of an ester oil represented by the formula shown in Chemical Formula 1 below, and (A2) a first ester oil, a second ester oil and a third and a second oil that is at least one selected from the group consisting of ester oils. The first ester oil is a triester compound of a trihydric polyhydric alcohol and a higher fatty acid having 8 or more carbon atoms. The second ester oil is at least one selected from the group consisting of triester compounds and tetraester compounds of a tetrahydric polyhydric alcohol and a higher fatty acid having 6 or more carbon atoms. The third ester oil is a diester compound of a higher alcohol having 16 or more carbon atoms and N-acylglutamic acid having an acyl group having 10 or more carbon atoms. The second oil has a viscosity of 40 mPa·s or more at 30°C. Hydrocarbon oil is 10% by mass or less with respect to the mass of the cleaning composition. The amount of silicone oil is 5% by mass or less based on the mass of the cleaning composition. Water is 5% by mass or less with respect to the mass of the cleaning composition.

The cleaning composition of the present disclosure has a transparent appearance. The cleaning composition of the present disclosure can maintain transparency even when mixed with water.

The cleaning composition of the present disclosure has high detergency. For example, the cleansing composition of the present disclosure has high detergency against oily cosmetics.

The cleaning composition of the present disclosure can have a thickness when picked up. This can enhance usability of the cleaning composition of the present disclosure. Moreover, not only can the adhesion of the cleansing composition to the skin be enhanced, but also the area to be cleaned can be washed with a larger amount of the cleansing composition.

In addition, the user can use the cleansing composition without having an image of denaturation due to cloudiness of the cleansing composition. Therefore, the cleaning composition of the present disclosure can be applied to situations in which hands are used in a wet state.

The cleaning composition of the present disclosure has a certain degree of viscosity (thickness). This makes the cleaning composition of the present disclosure easy to pick up and use.
