Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emulsified cosmetic composition which is mildly irritating to skin and the like, has a good feeling in use and is excellent in storage stability.

[0002]

2. Description of the Related Art In recent years, many emulsifiers have been researched and developed and applied to cosmetics. Conventionally, various nonionic surfactants and anionic surfactants have been used as emulsifiers in emulsion cosmetics such as creams and emulsions.

In addition, cosmetics improve rough skin,
It is required to keep the skin moisturized for a long time, and various moisturizers and oils have been added. However, when blending a moisturizer or an oil agent in this way, it is necessary to blend a large amount of a surfactant in order to maintain the emulsified state, or to use a surfactant having a strong stimulative effect on the skin and the like. , There was a problem in terms of safety.

Further, in recent years, along with the increase in allergic constitutions such as hay fever and atopic dermatitis, cosmetics having extremely low irritation to skin and eye mucous membrane and having high safety have been demanded. Generally, among emulsifiers used in cosmetics, sorbitan monoalkylate and polyoxyethylene adducts of hardened castor derivatives are used as highly safe surfactants, but depending on the compounding ingredients such as moisturizers, A large amount of these surfactants must be used, which causes a problem in terms of usability.

[0005]

Therefore, the object of the present invention is to have a low irritation to the skin and the like, and a good feeling in use,
Moreover, it is to provide an emulsion cosmetic having excellent storage stability.

[0006]

Under such circumstances, the present inventor has conducted diligent studies and, as a result, has found that a 2-hydroxypropanediamine derivative represented by the following general formula (1), a salt thereof or a quaternary compound thereof, and a general description below. By using a surfactant selected from the amide compound represented by the formula (3) and the amine derivative represented by the following general formula (4), it is less irritating to the skin and the like, and has excellent usability and storage stability. The inventors have found that an emulsion-type cosmetic composition having the same can be obtained, and completed the present invention.

That is, the present invention provides the following component (A):
(B) and (C): (A) (a) The following general formula (1);
