Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition or an external preparation containing a moisturizing agent composition containing specific components,
More specifically, the present invention relates to a cosmetic or an external preparation using a moisturizer composition consisting of a water-soluble polyhydric alcohol having 3 or more valences, lecithin and 3-methyl-1,3-butylene glycol, and optionally a small amount of water.

[0002]

BACKGROUND OF THE INVENTION It is well known that moisture is closely related to the retention of youthful skin, and that moisturizing the skin is one of the important functions for the quality of cosmetics. Known moisturizers used in cosmetics or external preparations include polyhydric alcohols such as glycerin, 1,3-butylene glycol and sorbitol, and in addition to them, pyrrolidonecarboxylic acid which is the main component of NMF (natural moisturizing factor). There are salts and lactates. In recent years, sodium hyaluronate produced by microorganisms has also been used.

Further, the moisturizer acts as a water retention agent for the cosmetics and the external preparation itself, and also plays an important role of contributing to maintaining the stability of the system. Trihydric or higher polyhydric alcohols such as glycerin and sorbitol have excellent moisturizing properties and water retention properties, and are used as the most versatile moisturizing agents in terms of safety, stability, and price.

As a necessary condition to be provided as a moisturizer,
It is desirable to be able to retain moisture for a long time without being affected by environmental conditions (temperature, humidity, wind, etc.), particularly regardless of the ambient humidity. However, generally, the moisture absorption amount and the release amount of any humectant are affected by the ambient humidity because of the vapor pressure. For example, in the case of glycerin, the temperature is 2
The equilibrium water content at 5 ° C is 60% when the relative humidity is 75%,
When the relative humidity is 33%, it is 15%, and in the case of sorbitol, when the relative humidity is 75%, it is 50%, and when the relative humidity is 33%, it is 5%. Occurs.

When the ambient humidity is low as described above, there is a problem in that the moisturizing agent itself releases the retained water and the water retention amount becomes low. Therefore, even when a cosmetic or an external preparation containing a moisturizing agent is used, moisture is lost from the skin over time under low humidity, and the moisturizing function is deteriorated. Therefore, as a moisturizer, it is necessary that the evaporation of water in a low humidity environment is slow.
In view of such a situation, the present inventors have earnestly studied to improve the moisturizing performance of cosmetics or external preparations to which a moisturizing agent is usually added.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cosmetic composition or an external preparation which solves the above problems and has excellent moisturizing properties and stability.

[0007]

Means for Solving the Problems The gist of the present invention comprises a moisturizer composition comprising a water-soluble polyhydric alcohol having a valence of 3 or more, lecithin and 3-methyl-1,3-butylene glycol, and optionally water. It is a cosmetic or an external preparation.

The cosmetic or external preparation of the present invention is characterized by being blended with a moisturizing agent composition comprising the above specific components. Lecithin used to obtain this moisturizing composition, soybean lecithin that can be obtained as a normal commercial product or reagent, including egg yolk lecithin, these are subjected to processing such as solvent fractionation, extraction, fractionation, etc. Purified lecithin, hydrogenated lecithin, fractionated lecithin and the like are used. In order to quickly dissolve lecithin in a water-soluble polyhydric alcohol having a valence of 3 or more and make it coexist, purified lecithin (mixed phospholipid) from which neutral oil is removed is preferable. Further, hydrogenated lecithin is preferable in consideration of oxidative stability. As for lysolecithin, those having a low lysolysis rate, that is, a deacylation rate (for example, a lysolysis rate of 70% or less) are preferable, and those having a high lysolysis rate can be used in combination with ordinary lecithin. Incidentally, a single product of only phosphatidylcholine such as high-purity synthetic diacylphosphatidylcholine precipitates in the moisturizer composition of the present invention,
It is not suitable because the stability of the composition is not good.

The water-soluble polyhydric alcohol having a valence of 3 or more is not particularly limited, and typical ones include glycerin, sorbitol, diglycerin, triglycerin, polyglycerin,
Erythritol, pentaerythritol, glucose,
There are galactose, fructose, sucrose, maltose, xylose, xylobiose, reduced products of oligosaccharides and the like, and these can be used alone or in combination. Of these, glycerin and / or sorbitol are preferred.

It is convenient to use a commercially available 3-methyl-1,3-butylene glycol (for example, manufactured by Kuraray Co., Ltd.). By blending this 3-methyl-1,3-butylene glycol, the moisturizing property of the composition (moisturizer composition) of the water-soluble polyhydric alcohol having 3 or more valences and lecithin is remarkably improved.

In the humectant composition of the present invention, the concentration of lecithin is 0.1 to 50% by weight, preferably 0.5 to.
40% by weight is preferred. When the concentration of lecithin is less than 0.1% by weight, the moisturizing properties of the moisturizer composition tend to be insufficient, and when it exceeds 50% by weight, lecithin is uniformly dissolved in the system of the composition. However, the insoluble matter tends to precipitate.

Further, a water-soluble polyhydric alcohol having a valence of 3 or more and 3
The weight ratio with -methyl-1,3-butylene glycol is 1:10 to 20: 1, preferably 1: 4 to 10: 1. When this ratio is larger than 1:10, lecithin cannot be stably dissolved in the water-soluble polyhydric alcohol, and the tendency to cause precipitation at room temperature (eg 20 ° C.) or low temperature (eg 5 ° C.) becomes large. On the other hand, when it is less than 20: 1, the composition does not become highly viscous and the moisturizing property does not reach a satisfactory level.

The humectant composition to be blended with the cosmetic or external preparation of the present invention contains the above-mentioned trihydric or higher polyhydric alcohol, lecithin and 3-methyl-1,3-butylene glycol, if desired, with stirring. Then, it can be prepared by mixing and dissolving uniformly. The composition thus obtained can be used as it is as a moisturizer composition. Alternatively, as described below, a small amount of water (about 10% by weight of the total composition) may be appropriately added to uniformly dissolve the above-mentioned components, and this may be used as a humectant composition.

The amount of water in the humectant composition according to the present invention may remain substantially non-aqueous, or a small amount of the necessary amount (described below) may be appropriately added. Usually, commercially available lecithin is about 0.1 to 3% by weight, and water-soluble polyhydric alcohol having a valence of 3 or more is 0.1% by weight or more (commercially available glycerin having a water content of 0.1 to 20% by weight, Some water-containing products such as sorbitol have a water content of 30% by weight) and 3-methyl-1,3-butylene glycol contains about 0.1 to 2% by weight of water. In some cases it may not be necessary to add water. Also,
When the water-soluble polyhydric alcohol having a valence of 3 or more is a solid sugar or sugar alcohol (sucrose, glucose, fructose, sorbitol, etc.), about 10 to about 5 of the entire composition is used.
It is necessary to add an appropriate amount of water of 0% by weight and dissolve it uniformly.

The humectant composition used in the present invention comprises the above-mentioned three components and, if necessary, a small amount of water dissolved therein, and it is desirable that the composition has a polarizing property. The composition having a polarizing property allows the composition to exhibit remarkable moisturizing properties. When water is added to the moisturizer composition, lecithin takes a specific association structure due to the interaction of the coexisting components to form a highly viscous liquid crystal, so that water evaporation from the composition occurs. Is thought to be suppressed.

The present invention is characterized in that it is a cosmetic or external preparation prepared by blending the aforementioned moisturizer composition. The cosmetic or external preparation of the present invention contains the specific moisturizing agent composition and at least an oily substance and / or water as essential components, and is a viscous or gel-like, oil-in-water emulsified or solubilized form. Form. That is, a viscous or gel-like cosmetic or external preparation is obtained by adding an oily substance to the above moisturizer composition under stirring and, if desired, a surfactant, a pigment, a dye, a fragrance, an antioxidant or the like. For example, it can be used as a cosmetic such as eye gel or cleansing gel or as a gel external preparation. The amount of oily substance mixed with the moisturizer composition is 10 times (weight)
The following is desirable, and when it exceeds this, separation of the moisturizing agent composition is caused.

Here, the oily substance is not particularly limited, and includes hydrocarbons, esters, oils and fats, waxes, higher fatty acids,

These can be used alone or as a mixture.

The humectant composition may be mixed with the above-mentioned oily substance and water with stirring, and if desired, a surfactant, a pigment, a dye, a fragrance, an antioxidant, an antiseptic agent, etc. It becomes an emulsified cosmetic or external preparation, and can be used as an external preparation such as a cosmetic such as cream, emulsion or emulsion lotion, or an ointment. At this time, the blending amount of water is desirably 10% by weight to 100 times (weight), and preferably 10% by weight to 20 times (weight), with respect to the humectant composition. The water may be mixed with a water-soluble or water-dispersible component such as a known surfactant or moisturizer.

Furthermore, when water and, if desired, surfactants, pigments, fragrances, antioxidants, preservatives and the like are added to the above moisturizer composition with stirring, the viscosity gradually decreases. A solubilized aqueous cosmetic or an external preparation (water content: 50% by weight or more) can be prepared, and it can be used as a cosmetic such as lotion or beauty essence or as a lotion-like external preparation. The water may be mixed with a water-soluble or water-dispersible component such as a known surfactant or humectant.
