Description
Technical Field
The invention relates to an oily solid cleaning cosmetic.
Background
In recent years, a large number of makeup cosmetics (make-up cosmetics) having excellent makeup retention have been developed. Therefore, the oily cleansing cosmetic having good compatibility with the makeup cosmetic (cosmetic compatibility) (メイクな processing み) is very suitable for makeup removal. The oily cleansing cosmetic is generally provided in a liquid or solid form.
Liquid oily cleansing cosmetics contain liquid oils as the main ingredient, and are known to have excellent compatibility with makeup cosmetics and to have a strong cleansing effect. However, since the liquid oily cosmetic has a low viscosity, there are problems that the oily cosmetic easily drips when used, and that the rubbing action is easily directly transmitted to the skin during use, which gives a strong feeling of burden or irritation to the skin.
On the other hand, solid oily cleansing cosmetics contain a solid oil such as wax in addition to a liquid oil, and by incorporating the liquid oil into a structure of a cabin (car house) formed by the solid oil, an oleogel structure is formed in which the fluidity of the liquid oil is suppressed. Such an oily solid cleansing cosmetic is easier to handle (handling) than a liquid cosmetic, and when used, a shear stress is applied to the oleogel structure, so that a part of the structure collapses and the liquid oil spreads on the skin, thereby being blended with the color cosmetic. Further, studies have been made to improve the spreadability and the cosmetic compatibility of an oily solid cleansing cosmetic, and for example, japanese patent application laid-open No. 2017-095375 proposes an oily solid cleansing cosmetic in which a polysaccharide fatty acid ester and a solid anionic surfactant are further blended in a liquid oil and a solid oil.
Disclosure of Invention
In the conventional oily solid cleansing cosmetic, the oil gel structure becomes firm at low temperatures such as in winter, and it is difficult to take out the oily solid cleansing cosmetic from a container, and the miscibility with the makeup cosmetic is sometimes deteriorated. If the solid oil is reduced to make the oleogel structure brittle in order to improve the usability at low temperatures, problems such as a decrease in hardness occur in a temperature cycle test, and the storage stability becomes insufficient. Although there is a method of enhancing the oil gel structure by using the oil gelling agent together with the cosmetic material of the above patent document, the method is still insufficient in terms of usability such as poor cosmetic compatibility and sticky feeling.
The present invention has been made in view of the above circumstances, and an object thereof is to provide an oily solid cleansing cosmetic which can be easily taken out from a container, has excellent miscibility with a color cosmetic, has good usability with less stickiness, and has sufficient storage stability in which hardness is not easily changed.
In order to solve the above problems, the present invention provides an oily solid cleansing cosmetic containing: (A) hydrogenated castor oil; (B) a hydrocarbon wax; (C) ester oil having a viscosity of 50 mPas or less at 25 ℃; and (D) a nonionic surfactant, wherein the content of the component (A) is 1-5% by mass, the content of the component (B) is 1-5% by mass, the content of the component (C) is 60% by mass or more, and the total content of the component (A) and the component (B) is 4-7.5% by mass.
The oily solid cleansing cosmetic of the present invention, having the above-described configuration, can achieve both good usability such as easy taking out from a container, excellent compatibility with a makeup cosmetic, less stickiness, and sufficient storage stability such that hardness is not easily changed.
The present inventors believe that the reason why the above-described effects are obtained is as follows: by blending hydrogenated castor oil, an oleogel structure comprising a hydrocarbon wax and the specific ester oil is stabilized, and by containing the respective components in the specific amounts, a sherbet (sherbet) -like structure can be formed which has sufficient storage stability, can collapse the oleogel structure with a small shear stress applied during use, does not feel sticky, and can easily spread ester oil. The present inventors also considered that the specific ester oil is excellent in the makeup miscibility and the spreadability, and that it is one of the reasons why good usability can be obtained.
In the oily solid cleansing cosmetic material of the present invention, the total content of the component (a), the component (B), the component (C), and the component (D) is preferably 97% by mass or more from the viewpoint of the makeup miscibility and the spreadability.
From the viewpoint of obtaining a use property that the component (C) is easily miscible with a makeup cosmetic and has less sticky feeling, it is preferable that 50% by mass or more of the ester oil of the component (C) has a viscosity of 20mPa · s or less at 25 ℃.
From the viewpoint of shape retention, the component (B) is preferably a polyethylene wax having a melting point of 70 to 110 ℃.
From the viewpoint of obtaining more excellent usability while sufficiently maintaining storage stability, the mass ratio (a)/(B) of the component (a) to the component (B) is preferably 1/5 to 1/1.
From the viewpoint of obtaining a user-friendly feeling less sticky, the oily solid cleansing cosmetic of the present invention preferably has a hardness of 0.3 to 1.2N at 25 ℃.
According to the present invention, an oily solid cleansing cosmetic can be provided which can be easily taken out from a container, has good usability with excellent miscibility with a makeup cosmetic and less stickiness, and has sufficient storage stability with hardness not easily changing.
