DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic or external preparation containing a humectant composition comprising a specific component,
More specifically, the present invention relates to a cosmetic or external preparation using a humectant composition comprising a trihydric or higher polyhydric alcohol, lecithin, 3-methyl-1,3-butylene glycol, and, if desired, a small amount of water.

[0002]

2. Description of the Related Art It is well known that moisturizing the skin is one of the important functions for the quality of cosmetics because moisture is closely related to the maintenance of youthful skin. Known humectants used in cosmetics or external preparations include polyhydric alcohols such as glycerin, 1,3-butylene glycol, and sorbitol. In addition, pyrrolidone carboxylic acid, which is a main component of NMF (natural moisturizing factor) There are salts and lactates. In recent years, sodium hyaluronate produced by microorganisms has also been used.

[0003] In addition, the humectant acts as a water retention agent for cosmetics and external preparations, and also plays an important role in 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 humectants with the highest versatility in terms of safety, stability, price and the like.

[0004] The necessary conditions to be provided as a humectant are:
It is desirable to be able to retain moisture for a long time without being affected by environmental conditions (temperature, humidity, wind, etc.), especially regardless of the surrounding humidity. However, in general, the amount of moisture absorption and the amount of release of any humectant are affected by the surrounding humidity due to the relationship of vapor pressure. For example, in the case of glycerin, temperature 2
The equilibrium water content at 5 ° C is 60% when the relative humidity is 75%,
15% when the relative humidity is 33%, 50% when the relative humidity is 75% and 5% when the relative humidity is 33% in the case of sorbitol. Occurs.

[0005] When the ambient humidity is low as described above, there is a problem that the humectant itself releases the retained water and the amount of water retention decreases. For this reason, even when using a cosmetic or an external preparation containing a humectant, moisture is lost from the skin over time under low humidity, resulting in a decrease in the moisturizing function. Therefore, as a humectant, it is necessary that the evaporation of water under a low humidity environment is slow.
In view of such a situation, the present inventors have intensively studied to improve the moisturizing performance of a cosmetic or an external preparation to which a humectant is usually added.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a cosmetic or external preparation having excellent moisture retention properties and excellent stability.

[0007]

The gist of the present invention is to provide a humectant composition comprising a water-soluble polyhydric alcohol having a valency of 3 or more, lecithin and 3-methyl-1,3-butylene glycol, and optionally water. Cosmetics or external preparations.

[0008] The cosmetic or external preparation of the present invention is characterized by comprising a humectant composition comprising the above specific components. Lecithin used to obtain this humectant composition is obtained by processing such as soybean lecithin and egg yolk lecithin, which can be obtained as ordinary commercial products and reagents, by subjecting them to processing such as solvent separation, extraction, and fractionation. Purified lecithin, hydrogenated lecithin, fractionated lecithin and the like are used. In order to rapidly dissolve and coexist lecithin in a tri- or higher-valent water-soluble polyhydric alcohol, purified lecithin (mixed phospholipid) from which neutral oil has been removed is preferred. Considering the oxidation stability, hydrogenated lecithin is preferred. As for lysolecithin, those having a low lysification rate, that is, a deacylation rate (for example, a lysification rate of 70% or less) are preferable, and those having a high lysification 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 humectant composition according to the present invention,
The composition is not suitable because of poor stability.

The water-soluble polyhydric alcohol having a valency of 3 or more is not particularly limited, and typical examples thereof 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.

As for 3-methyl-1,3-butylene glycol, it is convenient to use a commercially available product (for example, manufactured by Kuraray Co., Ltd.). By blending the 3-methyl-1,3-butylene glycol, the moisturizing properties of a composition (a moisturizing composition) of lecithin, a water-soluble polyhydric alcohol having a valence of 3 or more, and lecithin are remarkably improved.

In the humectant composition according to the present invention, the concentration of lecithin is 0.1 to 50% by weight, preferably 0.5 to 50% by weight.
40% by weight is good. If the concentration of lecithin is less than 0.1% by weight, the moisturizing properties of the humectant composition tend to be insufficient, and if it exceeds 50% by weight, lecithin is uniformly dissolved in the system of the composition. However, there is a tendency that insolubles precipitate.

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 precipitate at room temperature (for example, 20 ° C.) or low temperature (for example, 5 ° C.) increases. If the ratio is less than 20: 1, the composition does not become highly viscous and the moisturizing properties do not reach a satisfactory level.

The humectant composition to be incorporated in the cosmetic or external preparation of the present invention is prepared by heating and stirring the above water-soluble polyhydric alcohol having a valence of 3 or more, lecithin and 3-methyl-1,3-butylene glycol as required. And dissolving them uniformly and uniformly. The composition thus obtained can be used as it is as a humectant composition. Alternatively, as described below, a small amount of water (approximately 10% by weight of the entire composition) may be appropriately added to uniformly dissolve the components, and this may be used as a humectant composition.

The moisture content of the humectant composition according to the present invention may be substantially non-aqueous, or a small required amount (described below) may be appropriately blended. Usually, about 0.1 to 3% by weight of commercially available lecithin, and 0.1% by weight or more of a water-soluble polyhydric alcohol having 3 or more valences (commercially available products include glycerin having a water content of 0.1 to 20% by weight, There is also a water-containing product such as sorbitol having 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 is not necessary to add water. Also,
When the trihydric or higher water-soluble polyhydric alcohol is a solid saccharide or a sugar alcohol (sucrose, glucose, fructose, sorbitol, etc.), about 10 to about 5
It is necessary to add an appropriate amount of water of 0% by weight to dissolve uniformly.

The humectant composition used in the present invention is obtained by dissolving the above three components and, if necessary, a small amount of water. Preferably, the composition has a polarizing property. By making the composition polarizable, the composition exhibits remarkable moisturizing properties. Further, when water is added to the humectant composition, lecithin takes a specific association structure due to the interaction of the coexisting components and forms a highly viscous liquid crystal, so that water evaporates from the composition. Is considered to be suppressed.

The present invention is characterized in that it is a cosmetic or an external preparation containing the above-mentioned humectant composition. The cosmetic or external preparation of the present invention contains the specific humectant composition and at least an oily substance and / or water as essential components, and is a viscous or gel-like, oil-in-water emulsion or solubilized form. Form. That is, an oily substance and, if desired, a surfactant, a pigment, a dye, a fragrance, an antioxidant and the like are added to the humectant composition under stirring to obtain a viscous or gel cosmetic or external preparation. For example, it can be used as a cosmetic such as an eye gel or a cleansing gel or a gel-like external preparation. The amount of the oily substance to the humectant composition is 10 times (weight)
The following is desirable, and if it exceeds this, separation of the humectant composition is caused.

Here, the oily substance is not particularly limited, and hydrocarbons, esters, fats and oils, waxes, higher fatty acids,
These include higher alcohols, silicone-based substances, sterols, resins and the like. Examples of these include liquid paraffin, isoparaffin, petrolatum, squalane,

These can be used alone or as a mixture.

The oil-in-water type is obtained by incorporating the above-mentioned oily substance and water and, if desired, a surfactant, a pigment, a coloring matter, a fragrance, an antioxidant and a preservative into the above-mentioned humectant composition under stirring. It becomes an emulsified cosmetic or external preparation, and can be used, for example, as a cosmetic such as cream, emulsion, emulsified lotion, or an external preparation such as an ointment. At this time, the mixing amount of water is desirably 10% by weight to 100 times (weight), preferably 10% by weight to 20 times (weight) with respect to the humectant composition. The water may contain a water-soluble or water-dispersible component such as a known surfactant or humectant.

Furthermore, as water is added to the humectant composition under stirring and, if desired, a surfactant, a dye, a fragrance, an antioxidant, a preservative, and the like are added, the viscosity gradually decreases. Solubilized aqueous cosmetics or external preparations (moisture content: 50% by weight or more) can be used, for example, as cosmetics such as lotions and serums, and as lotion-like external preparations. In addition, a water-soluble or water-dispersible component such as a known surfactant or humectant may be added to the water.

Thus, according to the present invention, cosmetics and ointments such as creams, emulsions, lotions, essences, cleansing gels and the like containing the humectant composition comprising the above specific components,
External preparations such as gels can be obtained, as well as skin care cosmetics such as moisture gels and packs, and makeup cosmetics that are expected to have a moisturizing effect such as emulsified foundations, emulsified eye shadows, and nail treatments. . In addition, quasi-drugs for skin inflammation with dryness of the skin such as irritations, cracks, itching and atopy,
An external preparation such as a pharmaceutical ointment or gel preparation can also be used.
