Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel cosmetic, and more particularly, it has good usability due to moderate viscosity, good stability over time, and shows good hair styling properties when applied to hair. The present invention relates to a gel cosmetic that is excellent in cleansing effect as a cleansing agent when applied to the skin and is gentle on skin and hair.

[0002]

2. Description of the Related Art Conventionally, gel cosmetics have been widely used in hair cosmetics such as hair styling preparations, cleansing preparations for makeup cosmetics and the like. Usually, these gel cosmetics include anionic surfactants and oils, and in some cases, gel cosmetics containing a mixture of polyhydric alcohol as a main component of the gel, and water-soluble polymers containing water-soluble components. Thickened aqueous gel compositions and the like are often used. In general,
The former contains a relatively large amount of surfactants and oils, and is often used in hair styling and cleansing agents because it is often excellent in terms of functions such as hair styling and cleansing abilities. In recent years, gel cosmetics using a nonionic surfactant instead of an anionic surfactant have been studied in view of a demand for a base that is more gentle on skin and hair.

[0003]

However, gel cosmetics using the above-mentioned nonionic surfactants use a large amount of surfactants and oils, so that only a small amount of raw materials such as surfactants and oils are used. It may cause large deterioration such as odor and change in gel state of the gel cosmetic as a whole, even if the cosmetic deteriorates over time, so it may be difficult to obtain a gel cosmetic that is stable over time. there were. Therefore, there is a demand for the development of a gel cosmetic which has excellent effects in terms of hair styling and cleansing power and is stable over time by using a nonionic surfactant or an oil agent as a main component of the gel. Was.

[0004]

[Means for Solving the Problems] In view of such circumstances,
The present inventors have conducted intensive studies to overcome the above-mentioned drawbacks, and as a result, a nonionic surfactant, a liquid higher alcohol, a liquid oil and a gel cosmetic in which a specific amount of each of water is combined, the above-mentioned effects can be obtained. The present inventors have found that an excellent gel cosmetic having the same can be obtained, and completed the present invention based on this finding.

That is, the present invention provides the following components (A) to
(D), (A) 1 to 50% by mass of nonionic surfactant (B) 0.1 to 20% by mass of liquid higher alcohol (C) 0.1 to 20% by mass of liquid oil (D) 1 to 70% by mass of water % Of a gel cosmetic.
