Description

Oily cosmetics

The present invention relates to oil-based cosmetics.

Oil-based cosmetics are used in a wide range of applications such as skin care, hair care, and make-up because they have high affinity for the skin, excellent usability, high moisturizing power, and high makeup durability. Not only the combination of components but also the physical property values such as viscosity may be adjusted according to the application.

For example, eyeliner makeup, which is one of the oily cosmetics, is a makeup that can emphasize the eyes and make them look bigger by putting a line on the contour of the eyes. From the method of drawing on the contour, it is required to have both ease of drawing that allows smooth lines to be drawn without fading and no bleeding, and high makeup durability that can withstand eyelid movement, tears, sweat, and water. In addition, lipstick, which is another item, is required to be applied along the contour of the lips and to have high makeup durability that can withstand the movement and water of the lips. Furthermore, since the foundation is applied to the entire face, it is easily exposed to sweat, tears, and water. When applying the foundation, it is necessary to have no bleeding (it rides evenly on the skin without getting into wrinkles), and in addition, since the application area is wide, very high makeup durability is required. In addition, since these items contain a high amount of pigment, the dispersity of the pigment during production, the redispersibility of the pigment over time, and the stability at high temperatures are also very important.

Furthermore, for example, in the case of eyeliner, its viscosity is very important from the viewpoint of usability. When the viscosity is high, there is an advantage that it does not easily bleed, and when the viscosity is low, there is an advantage that it is easy to draw smoothly. Generally, these functions are in a trade-off relationship. Viscosity is also very important in terms of pigment dispersibility during manufacturing, pigment redispersibility over time, and high temperature stability, all of which may be a problem in the development of low-viscosity cosmetics. Studies have been made to further improve quality while taking advantage of it, for example, one or more selected from hydrophilic silica and derivatives of polyhydroxystearic acid, polyhydroxystearate and polyhydroxystearic acid. There is a technique for imparting high stability to the oil-based cosmetics contained (see Patent Document 1). In addition, in order to obtain water resistance, skin oil resistance, preventive effect of makeup disintegration, makeup durability, spreadability, and smooth usability, acrylic-silicone graft copolymer 3 to 20% by weight and spherical fine powder. There is also a technique for providing a liquid make-up cosmetic containing 5 to 30% by weight of a body and 10 to 70% by weight of a low boiling point silicone oil (see Patent Document 2).

JP-A-2019-119717 Japanese Unexamined Patent Publication No. 2002-047140

The metal oxide required for the function of cosmetics has a small particle size and a very high cohesive force. Especially in cosmetics in the low viscosity region, this cohesive force tends to be a problem, and a technique for treating the surface of a metal oxide in order to improve the pigment dispersibility during production and the pigment dispersibility over time is generally known. ing. Hydrophobicized metal oxides are often used in oil-based cosmetics composed of only oil-based components. In the conventional technique, in the development of oil-based cosmetics in a low-viscosity region containing a large amount of hydrophobized metal oxide, the hydrophobized metal oxide does not aggregate, and the hydrophobized metal oxide is redispersible after standing. It has been difficult to develop an oil-based cosmetic that is excellent, has high temperature stability, long-lasting makeup, and has no bleeding. Therefore, in the present invention, in an oil-based cosmetic containing 10 to 60% by mass of the hydrophobized metal oxide and having a viscosity at 25 ° C. of 500 to 5000 mPa · s, the hydrophobized metal oxide does not aggregate and is allowed to stand. The subject is the development of an oil-based cosmetic which is excellent in the redispersibility of the later hydrophobized metal oxide, and is excellent in high temperature stability, long-lasting makeup, and no bleeding.

In order to solve the above problems, we diligently examined resins, gelling agents, pigments, etc. In general, since a metal oxide can suppress aggregation by surface treatment with a treatment agent, a surface-treated metal oxide is often used when a large amount of metal oxide is contained. In the case of oil-based cosmetics, since the outer phase is oil-based, the surface treatment is a hydrophobic treatment. However, in the low viscosity region, in addition to suppressing the aggregation of the metal oxides, good compatibility between the metal oxides and the entire system is also required. Hydrophobization treatment If the metal oxide and the entire system are incompatible, even if the agglomeration of the pigments is suppressed, the pigments become non-uniform in the cosmetics, resulting in poor dispersibility during manufacturing or hydrophobicity over time. Sedimentation of the treated metal oxide occurs. The most important thing here is a thickener that imparts viscosity to the entire system, and as a result of the study, it was found that pigment aggregation is least likely to occur when the dextrin fatty acid ester and the organically modified clay mineral are combined. As a result of further diligent studies, by combining silicone film forming agents, dextrin fatty acid esters, organically modified clay minerals, hydrophobized metal oxides, and volatile oils, hydrophobic treated metal oxides in low-viscosity oily cosmetics Has led to the development of an oil-based cosmetic that does not aggregate and has excellent redispersibility of the hydrophobized metal oxide after standing, high temperature stability, long-lasting makeup, and no bleeding.

That is, the present invention has the following components (A) to (E);
(A) Silicone film forming agent (B) Dextrin fatty acid ester (C) Organic modified clay mineral (D) Hydrophobized metal oxide 10 to 60% by mass
(E) The present invention relates to an oil-based cosmetic containing a volatile oil agent and having a viscosity at 25 ° C. of 500 to 5000 mPa · s.

It is a schematic diagram of the measurement using a grind meter. It is a photograph that each of Example 1 and Comparative Example 2 were shaken twice and allowed to stand at room temperature of 25 ° C. for 1 hour.

The details of the present invention will be described below. In addition, in this specification, "-" shall mean the range including the numerical values before and after it. Further, the "average particle size" in the present invention is a median diameter D50 value obtained by measurement with an image analysis device (Luzex AP, manufactured by Nireco Corporation). In the case of an asymmetrical shape, in the present invention, the median diameter D50 obtained from the distribution of the largest particle diameter is used as the average particle diameter.
