JP7621787B2 - Water-in-oil emulsified solid cosmetics - Google Patents

Description

The present invention relates to a water-in-oil type emulsion solid cosmetic. More specifically, it relates to a water-in-oil type emulsion solid cosmetic that has a high concealing effect and correcting effect, spreads lightly, and gives a natural finish.

Traditionally, foundations and concealers have been known as cosmetics with strong correction and concealing effects. Recently, there has been a demand for more unique makeup, and there is an increasing need for cosmetics with stronger correction and concealing effects.

Water-in-oil emulsified solid cosmetics are known as such cosmetics, and their formulations have been extensively studied. In water-in-oil emulsified solid cosmetics, increasing the ratio (internal aqueous phase ratio) obtained by dividing the amount of the internal aqueous phase components by the sum of the total aqueous phase components and the total oil phase components can give a refreshing and pleasant feel when used, while conversely, a low internal aqueous phase ratio tends to spread lightly but have an oily feel. It has also been found that by using fatty acid glyceryl esters or the like as surfactants, stable water-in-oil emulsified solid cosmetics can be obtained even when the internal aqueous phase ratio is high.

For example, Patent Document 1 discloses a water-in-oil emulsified solid cosmetic that contains a fatty acid glyceryl ester, an aqueous component, an oily component, and a powdery component, the oily component containing a solid oil and an oil-soluble coating agent, and the powdery component containing titanium oxide and a pearl pigment. This cosmetic has excellent corrective and concealing effects, but it has been found that further improvements are desirable in terms of smoothness and fit during use.

International Application Publication No. 2018/199160

The present invention was made in consideration of the above-mentioned technical situation, and aims to provide a water-in-oil type emulsified solid cosmetic product with an internal aqueous phase ratio of a certain level or more, which is a makeup cosmetic product with improved usability, and in particular, which combines smoothness and a good fit.

The water-in-oil emulsified solid cosmetic preparation according to the present invention comprises:
(A) acyclic volatile silicones,
(B) hydrogenated polyisobutene having a mass average molecular weight of 300 to 5,000;
(C) a fatty acid glyceryl ester which is one or more selected from the group consisting of glyceryl monoisostearate, diglyceryl diisostearate, and glyceryl oleate;
(D) an aqueous component;
It is characterized by comprising (E) an oil component and (F) a powder component.

The water-in-oil emulsion solid cosmetic of the present invention has a high degree of fit and can be applied thickly, resulting in a high degree of concealment and a natural finish, and it spreads well on the skin and fits well.

The following describes in detail the embodiments of the present invention.

The water-in-oil emulsion solid cosmetic composition according to the present invention (hereinafter, simply referred to as "solid cosmetic composition") has the following properties:
(A) acyclic volatile silicones,
(B) hydrogenated polyisobutene,
(C) fatty acid glyceryl esters,
(D) an aqueous component;
The composition contains an oil component (E) and a powder component (F). Each of these components will be described below.

(A) Acyclic volatile silicone The solid cosmetic preparation according to the present invention contains acyclic volatile silicone. Silicone is an organosilicon compound whose main skeleton is composed of siloxane bonds. In the present invention, an acyclic silicone that does not have a cyclic structure is used. Here, the acyclic silicone is a silicone that includes a linear or branched chain structure, and silicone that has only a linear structure is preferred. In particular, dimethylpolysiloxane (polydimethylsiloxane), whose repeating unit is derived from dimethylsiloxane, is preferred.

The silicone that can be used in the present invention is volatile. Specifically, the volatile content when left to stand at 105°C for 3 hours is preferably more than 5% by mass, and more preferably more than 40% by mass. If the volatility is too high, the handling and safety may be reduced, so the boiling point is preferably 100°C or higher, and more preferably 150°C or higher.

Silicones are generally mixtures of polymers with different degrees of polymerization, and the lower the average degree of polymerization, the lower the volatility, and at the same time, the lower the dynamic viscosity and specific gravity tend to be.

There are various types of such non-cyclic volatile silicones, such as the KF-96 series (product name, manufactured by Shin-Etsu Chemical Co., Ltd.). In the present invention, one can be selected from these depending on the purpose.

The amount of the non-cyclic volatile silicone (A) in the solid cosmetic according to the present invention is usually within the range of 5 to 25% by mass, preferably 8 to 20% by mass, and more preferably 10 to 15% by mass, based on the total amount of the cosmetic. If the amount is less than 5% by mass, the smooth feel may be lost, and if it exceeds 25% by mass, the usability of the cosmetic may be impaired.

Cyclic volatile silicones can also be combined as long as the effects of the present invention are not impaired. In general, based on the total mass of the non-cyclic volatile silicone and the cyclic volatile silicone, the blending ratio of the non-cyclic volatile silicone is 80 mass% or more, preferably 90 mass% or more, and particularly preferably 100 mass%, i.e., no cyclic volatile silicone is included.

(B) Hydrogenated polyisobutene The solid cosmetic preparation according to the present invention contains hydrogenated polyisobutene. Hydrogenated polyisobutene is a volatile hydrocarbon obtained by copolymerizing isobutene and n-butene and then hydrogenating the copolymer, and is also called liquid isoparaffin. In the present invention, hydrogenated isobutene having a mass average molecular weight of 300 to 5000 is used, and preferably 500 to 3000. By using hydrogenated polyisobutene, secondary adhesion during use can be suppressed, and the covering power and fit during use can be improved.

Various types of hydrogenated polyisobutene are commercially available, such as Parleam 18, Parleam 24, Parleam 46 (all manufactured by NOF Corporation) and refined polybutene HV-100F(S)(SB) (manufactured by Nippon Natural Products Co., Ltd.). In the present invention, one of these can be selected and used according to the purpose.

The amount of hydrogenated polyisobutene (B) in the solid cosmetic according to the present invention is usually within the range of 0.1 to 10% by mass, and preferably 0.5 to 7% by mass, based on the total amount of the cosmetic. If the amount is less than 0.1% by mass, the fit may be impaired, and if it is more than 10% by mass, it may not blend well with the skin.

(C) Fatty acid glyceryl ester The solid cosmetic according to the present invention contains a fatty acid glyceryl ester. The fatty acid glyceryl ester is one or more selected from the group consisting of glyceryl monoisostearate, diglyceryl diisostearate, and glyceryl oleate. Any one of them may be used, or two or more may be used in combination. Among these, glyceryl oleate includes glyceryl monooleate, glyceryl dioleate, and glyceryl trioleate, with glyceryl monooleate being preferred. Glyceryl oleate may also be a mixture of one or more selected from glyceryl monooleate, glyceryl dioleate, and glyceryl trioleate, but it is preferred that it contains glyceryl monooleate. The content of glyceryl monooleate in such a mixture is preferably 40% by mass or more, more preferably 60% by mass or more, and particularly preferably 85% by mass or more, based on the total amount of the mixture of glyceryl oleate.

These fatty acid glyceryl esters can be selected from those that have been used in cosmetics. Specifically, examples of glyceryl monoisostearate include NIKKOL MGIS (product name, manufactured by Nikko Chemical Co., Ltd.), etc., examples of diglyceryl diisostearate include WOGLE-18DV (product name, manufactured by Matsumoto Kosho Co., Ltd.) and EMALEX DISG-2 (product name, manufactured by Nippon Emulsion Co., Ltd.), etc., and examples of glyceryl oleate include NIKKOL MGO (product name, manufactured by Nikko Chemical Co., Ltd.), etc.

The amount of fatty acid glyceryl ester (C) in the solid cosmetic according to the present invention is usually within the range of 0.5 to 5% by mass, and preferably 1.0 to 3.0% by mass, based on the total amount of the cosmetic. If the amount is less than 0.5% by mass, the fit may be impaired, and if it is more than 10% by mass, usability such as a refreshing feeling after use may be inferior.
