Description

The present invention relates to oil-based cosmetics.

Conventionally, oil-based cosmetics containing liquid oily components such as hair oil and body oil as main components have been known. For example, there is one disclosed in Patent Document 1.

However, it is difficult for conventional oil-based cosmetics such as hair oil disclosed in Patent Document 1 to contain water and a water-soluble moisturizing component, and for example, it is not possible to impart moisture and softness to hair. In addition, it is difficult to mix the water-soluble components, and it is difficult to impart the performance caused by various water-soluble components.

On the other hand, the present inventor is studying an oil-based cosmetic which is an oil gel containing polyhydric alcohol and water by forming a liquid crystal gel using a specific surfactant. However, oil gels are generally inferior in fluidity, and it is difficult to take them out of a container or spread them on the palm, skin, or hair, and they may be inferior in usability and skin compatibility. Even if an attempt was made to reduce the viscosity of an oil gel by adjusting the viscosity using a general slimming agent, the viscosity was not reduced until the fluidity was excellent, or even if the viscosity was reduced, the oil gel structure could not be maintained and the oil gel was sometimes destroyed. .. Therefore, there is a demand for oil-based cosmetics capable of obtaining cosmetics having excellent fluidity while maintaining the structure of the oil gel.

Therefore, an object of the present invention is to provide an oil-based cosmetic which can obtain a cosmetic having excellent fluidity while maintaining the structure of the oil gel.
