Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an emulsified cosmetic composition,
More specifically, the present invention relates to a higher fatty acid salt emulsion type emulsified cosmetic composition having high safety to the skin and excellent stability over time.

[0002]

2. Description of the Related Art Generally, higher fatty acids have a thixotropic gel form in an aqueous solution of 10% by weight or less,
Since it has a good feel when applied to the skin and has a good emulsification property of oil, it has been widely used in emulsion cosmetics since ancient times, particularly as a salt.

By the way, it is difficult for an emulsified cosmetic to maintain the stability of the system for a long period of time. Above all, it is particularly difficult in emulsions with high fluidity, and creaming, aggregation, and coalescence easily occur, so measures such as refining the particles, increasing the viscosity of the outer phase, and adjusting the specific gravity of the inner and outer phases are taken. Has been.

In addition to the above-mentioned instability factors, cosmetics of higher fatty acid salt emulsion type often have a change in odor or spots during long-term storage. For example, a sodium salt or potassium salt of a higher fatty acid having 16 or more carbon atoms has good emulsifying property and has no problem in terms of safety to the skin, but has a Kraft point of room temperature or higher and crystallizes at room temperature. Will occur. Therefore, when a higher fatty acid salt having 16 or more carbon atoms is used, usually a surfactant such as a nonionic fatty acid monoglyceride having an HLB of less than 10 is used in combination to suppress crystal precipitation and improve the stability of the emulsion system over a long period of time. I kept it.

However, if electrolyte salts are mixed in the system, particularly 0.01 mol or more, the emulsified state deteriorates, and it becomes impossible to secure long-term stability of the emulsified composition.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances. The object of the present invention is to emulsify higher fatty acid salt emulsion-type emulsion cosmetics, especially electrolyte salts in the system. An object of the present invention is to provide an emulsified cosmetic composition in which the emulsified system is stable for a long period of time even when it is contained in an amount of 01 molar concentration or more, does not cause odor or lumps, and is highly safe to the skin.

[0007]

Means for Solving the Problems As a result of intensive studies to solve the above problems, the present inventors have found that in higher emulsified fatty acid salt emulsion cosmetics, especially 0.01% of electrolyte salts is used.
Even when it is contained in a molar concentration or more, by using a combination of nonionic surfactants with HLB of 10 or more, the emulsion system is stable for a long period of time, and it does not cause odor or spots and is safe for the skin. It was found that an oil-in-water emulsified cosmetic composition having high properties and excellent properties can be obtained, and completed the present invention.

That is, according to the present invention, (A) a higher fatty acid, (B) a nonionic surfactant having an HLB of 10 or more,
And (C) an emulsified cosmetic composition containing electrolyte salts.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

The higher fatty acid as the component (A) is a fatty acid having 16 or more carbon atoms, and examples thereof include palmitic acid, stearic acid, behen (behenin) acid, oleic acid, 12-hydroxystearic acid, isostearic acid, linoleic acid, Linoleic acid, eicosapentaenoic acid (EPA),
Examples thereof include docosahexaenoic acid (DHA). These higher fatty acids may be used alone or in combination of two or more. The blending amount thereof is preferably 0.5 to 5.0% by weight, more preferably 0.8 to 3.0% by weight. If it is less than 0.5% by weight, sufficient emulsification is difficult, while if it exceeds 5.0% by weight, it is not preferable in terms of safety to the skin.

In the present invention, these higher fatty acids are used in the form of salts. The higher fatty acid can be converted into a salt by a conventional method. The salt-forming substance is not particularly limited as long as it shows basicity in an aqueous solution system, and for example, alkali metal salts such as sodium salt and potassium salt, alkanolamine salts and the like are preferably used. Any one or more of these salt-forming substances can be used. The amount of the salt-forming substance blended is preferably 1/10 equivalent or more with respect to the higher fatty acid. If the amount is less than 1/10 equivalent, the higher fatty acid that is not ionized is likely to crystallize, and crystals may precipitate at low temperature over time, which may impair stability.

When two or more higher fatty acids are used, the higher fatty acids may be salted and then mixed, or the higher fatty acids may be mixed and then neutralized. In producing the emulsified cosmetic of the present invention, a salt of a higher fatty acid may be mixed with other components and emulsified, or the higher fatty acid may be mixed with an oil component and the salt-forming substance may be mixed with an aqueous component. However, a higher fatty acid salt may be formed during emulsification.

The nonionic surfactant as the component (B) has an HLB of 10 or more. When the HLB is less than 10, the emulsified state deteriorates and the emulsified particles aggregate and coalesce. In the present invention, this HLB is expressed by the following formula 1.
