Description

The present invention relates to oil-based solid cosmetics.

Conventionally, lip cosmetics that give a moisturizing feeling and a care effect to the lips have been required, and various lip balms, lip balms, and the like have been developed.
For example, Patent Document 1 describes that an oil-based cosmetic containing a hydrocarbon having a specific melting point, a water-holding oil, and a dextrin fatty acid ester is excellent in moisturizing effect, shape retention, and usability.
It is also required to moisturize and color the lips at the same time, but if a colorant is added to a lip balm type cosmetic such as the oily cosmetic of Patent Document 1, the dispersibility is poor. In some cases, it was sufficient and the color development was poor.
Therefore, studies have been made to impart moisturizing properties to the lipstick itself, and liquid lipsticks having a glossy feeling and a moisturizing feeling have been developed. For example, in Patent Document 2, a lip cosmetic containing a wax having a specific melting point, a semi-solid oil, a liquid oil, and a dextrin fatty acid ester in a specific ratio suppresses rough lips while being glossy, and has a care effect. It is stated that it will last.

JP-A-2007-2620033 JP-A-2017-95388

However, the lip cosmetics described in Patent Document 2 are liquid lipsticks, and after application, they may flow without staying firmly on the lips, and the color may spread around the lips. In addition, although the gloss and color are good, there is also a problem that unnaturalness is conspicuous when the saturation is high.
In general, solid lipsticks are suitable for firmly adhering lipsticks to the lips. Therefore, the present inventors are oil-based solid cosmetics, which are highly saturated, have a natural color, and have an excellent moisturizing feeling. I thought about developing something.
However, oil-based solid cosmetics are often made into a solid state by using wax, and are hard and difficult to remove with an applicator. For this reason, the elongation at the time of application is poor, and the color development and saturation are not sufficient.
The present invention provides an oil-based solid cosmetic that has a moisturizing feeling and a care effect, is easy to spread at the time of application, and has excellent color development and saturation.

The present inventor uses a semi-solid oil having a specific melting point in a specific ratio, reduces the amount of wax, and makes it solid with a dextrin fatty acid ester or the like, so that it has an appropriate hardness and is easy to spread at the time of application. It has been found that an oil-based solid cosmetic that has good dispersibility of the colorant, good color development, high saturation at the time of application, excellent moisturizing effect and its durability, and less likely to sweat over time can be obtained.

In the present invention, the following components (A), (B), (C), (D) and (E):
