Description

Cosmetic composition containing a water-soluble crystalline material {Cosmetic composition containing hydrophilic crystalline materials}

The present invention relates to a cosmetic composition comprising a water-soluble crystalline material, and more particularly, to stabilize the water-soluble crystalline material in the oil-disperse formulation, various water-soluble substances can be applied to the cosmetic formulation, excellent formulation stability and water-soluble even at high temperatures It relates to a cosmetic composition in which the titer of the crystalline substance is stable.

Lips are bordered at the edges of the mouth, developed only in mammals, and appear red because they have many capillaries. The lips constantly contract and swell, which is one of the most active parts of the body. The lips do not have pores and do not secrete sweat or sebum, so no natural moisturizing film is formed. The skin around the lips is thinner and softer than other skins, so it easily cracks and cracks in dry weather. In addition, since the lips are always exposed to the outside, they are easily stimulated by environmental factors such as ultraviolet rays, air pollutants and dry climate.

Lips are bordered at the edges of the mouth, developed only in mammals, and appear red because they have many capillaries. The lips constantly contract and expand, which is one of the most moving parts of the body. The lips do not have pores, so they do not secrete sweat or sebum, so a natural moisturizing film is not formed. The skin around the lips has a much thinner and softer layer of stratum corneum than other skins, so moisture easily evaporates and cracks well in dry weather. In addition, since the lips are always exposed to the outside, they are easily stimulated by environmental factors such as ultraviolet rays, air pollutants and dry climate.

Therefore, most of the lip cosmetics are made of wax or oil with a focus on preventing moisture evaporation, and when applied to the lips, the oil-soluble components do not evaporate well to maintain moisture for a long time.

However, recently, as consumers tend to prefer products that are more effective in cosmetics and products that can solve various skin worries, lip cosmetics are required for various skin care effects as well as preventing color and moisture evaporation. For example, skin care products such as moisturizing moisture, anti-wrinkle, brightening the lip color, exfoliating the lips, and thickening the lips There is also a great demand for lip products.

Although various effects as described above are required in a lip product, raw materials that can provide such effects are much more diverse and kinds of water-soluble substances than usefulness. However, almost all of the lip cosmetics consisted of useful substances, making it difficult to add large amounts of water-soluble substances.

When a large amount of water-soluble substance is added to an oil-soluble solid stick, high-density water-soluble components sink to the bottom or combine with specific groups of the pigment to prevent uniform dispersion of the pigment, or those with strong crystallinity are difficult to use in large quantities.

Attempts have been made to stabilize water soluble materials on oil soluble sticks. In Korean Patent Publication No. 10-1999-0009865, a method of stabilizing a moisturizing component using an emulsification process of a polyhydric alcohol, a water-soluble polymer, a wax, and a surfactant has been invented. This method is also a method to keep the water-soluble substance stable and stable for a long time, but this composition has a relatively high content of oils and waxes that are not involved in dissolving various oils, so that the water-soluble lip cosmetics can contain the actual water-soluble crystalline substance. There is not much that can be done. In addition, in the case of a substance which is not dissolved in polyhydric alcohol but dissolved only in purified water, a composition in which a large amount of purified water is difficult to stabilize is disadvantageous in that it is difficult to use a large amount of a water-soluble substance.

Accordingly, the present inventors have solved the above problems and studied a method that can stably contain a substance having excellent skin efficacy among water-soluble crystalline substances in oil-soluble cosmetics, stably mixed with purified water with water-soluble crystalline substance When the amphiphilic polymer, purified water, and surfactant are included together, it was found that the water-soluble crystalline substance can be stably dispersed in an oil-soluble cosmetic material without precipitation or separation, thereby completing the present invention.

Accordingly, it is an object of the present invention to provide a cosmetic composition in which a water-soluble crystalline substance having excellent skin efficacy is stably dispersed in an oil-soluble cosmetic composition.

In order to achieve the above object, the present invention provides a cosmetic composition containing a water-soluble crystalline material, an amphiphilic polymer, purified water and a surfactant as an active ingredient.

The cosmetic composition containing the water-soluble crystalline substance, amphiphilic polymer, purified water and surfactant of the present invention enables easy and stable application of useful care effects to the oil-soluble cosmetics that are not obtained from general oil-soluble substances. Therefore, according to the efficacy of the water-soluble crystalline material it can be given a variety of efficacy, such as excellent moisturizing power, exfoliation, color improvement.

The present invention provides a cosmetic composition containing a water-soluble crystalline substance, an amphiphilic polymer, purified water and a surfactant as an active ingredient.

Hereinafter, the present invention will be described in more detail.

The cosmetic composition includes a water-soluble crystalline substance, an amphipathic polymer, purified water and a surfactant as an active ingredient, it is possible to stably support a large amount of water-soluble crystalline substance in the oil-soluble lip cosmetics.

The water-soluble crystalline material used as an active ingredient in the present invention is limited to a material that is solid and water-soluble at room temperature, trehalose (Trehalose), betaine (Betine), ascorbyl acid 2-glucoside (Ascobyl acid 2 -Glucoside, urea (Urea), niacinamide (Niacinamide), acetyl glucosamine (Acetyl Glucosamine) and panthenol (panthenol) is one or more selected from the group consisting of.

The water-soluble crystalline material of the present invention may be included in 0.1 to 6% by weight, more preferably 1 to 5% by weight relative to the total weight of the cosmetic composition for lips. This is undesirable because less than 0.1% by weight is less effective, more than 6% by weight is difficult to uniformly disperse in the formulation and there is a risk of crystal precipitation after long term storage.

Amphiphilic polymer used in the present invention is a material that can be mixed well in both the aqueous and oily components, for example, lauryl polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone , Polyethylene glycol / polypropylene glycol 10/7 dimethicone copolymer (PEG / PPG 10/7 dimethicone copolymer), polyethylene glycol-9 polydimethylsiloxyethyl dimethicone, polyethylene glycol / polypropylene glycol 17/17 Butyl Ether, Polyhydroxystearic acid, Dipentaerythrityl Tri-Polyhydroxystearate, Iononanoyl Di Glycerin / Dilinoleic Acid Copolymer, Polyglyceryl-2 Isostearate / Dimer Dilinole Sites copolymers and the like (Polyglyceryl-2 Isostearate / Dimer Dilinoleate Copolymer), pentaerythrityl di trityl tree in a dual-polyhydroxy stearate is the most suitable (Dipentaerythrityl Tri-Polyhydroxystearate).

Amphiphilic polymer of the present invention may be included in 2 to 15% by weight, more preferably 3 to 10% by weight relative to the total weight of the cosmetic composition. When the above range is satisfied, the property of stabilizing purified water dissolving a water-soluble substance is very excellent and well mixed with oil-soluble cosmetics. If it is less than 2% by weight, the role of stabilizing purified water is insufficient, and if it is more than 15% by weight, it is not preferable because of its high viscosity and poor applicability of the cosmetic.

The surfactant used in the present invention is preferably a surfactant having a relatively low HLB value, and specific examples thereof include sorbitan isostearate, sorbitan oleate, and sorbitan sesquioleate. ), Sorbitan stearate and the like, among which sorbitan isostearate or sorbitan sesquioleate is most preferred in terms of emulsion stability.

The surfactant of the present invention is included in an amount of 0.2 to 5% by weight, more preferably 0.5 to 3% by weight based on the total weight of the composition for lips. When the above range is satisfied, a mixture of purified water, amphiphilic polymer, and water-soluble crystalline substance may be further stabilized in the oil-soluble lip composition. If it is less than 0.2% by weight, the effect of stabilizing purified water is insufficient, and if it is more than 5% by weight, lips are not tightened or white foreign substances are formed.

Purified water in the present invention serves to dissolve the water-soluble crystalline material, the purified water of the present invention may be included in 0.5 to 9% by weight, more preferably 1 to 7% by weight relative to the total weight of the oil-soluble lip cosmetic composition. If it is less than 0.5 wt%, the effect of dissolving the water-soluble crystalline substance is insufficient, and if it is more than 9 wt%, it is not preferable because it is not stabilized in oil-soluble cosmetics.

The cosmetic composition contains a cosmetically or dermatologically acceptable medium or base. This includes all formulations suitable for topical application, including all formulations to which the oil-soluble composition can be applied. These compositions may be prepared according to conventional methods in the art.

The cosmetic composition of the present invention may be formulated for lips, and more specifically, it may be a formulation such as lipstick, lip gloss, lip balm, lip tint, lip care, lip treatment, but is not limited thereto.

The oil-soluble cosmetic composition may contain other ingredients in addition to the above-mentioned substances, preferably within the range that does not impair the main effect, and may have a synergistic effect on the main effect, other cosmetics in addition to the active ingredient of the present invention Depending on the formulation of the composition or the purpose of use, those skilled in the art can appropriately select and blend without difficulty.

For example, the cosmetic composition may contain a skin absorption promoting substance to increase the effect. In addition, the cosmetic composition of the present invention may include a material selected from the group consisting of water-soluble vitamins, oil-soluble vitamins, polymer peptides, polymer polysaccharides, sphingolipids and seaweed extract. In addition, the cosmetic composition of the present invention may include other components which are usually formulated into the cosmetic composition as necessary, in addition to the essential components, and examples thereof include fats and oils, humectants, emollients, organic and inorganic pigments, organic powders, Ultraviolet absorbers, preservatives, fungicides, antioxidants, plant extracts, pH adjusters, alcohols, pigments, flavorings, blood circulation accelerators, cooling agents, limiting agents and the like.

[Test Example 1] Analysis of content titer of water-soluble substance

The content titers of the water-soluble substances in Examples 1 and 2 and Comparative Example 3 were analyzed according to the following method. The results are shown in Table 2 below.

1. Titer analysis method of Example 1 and Comparative Example 3

1 g of Example 1 and Comparative Example 3 were precisely weighed and placed in ethanol and dispersed by ultrasonic waves. 20 mg of the component 18 was precisely weighed and dissolved in ethanol as a standard solution. The three liquids were tested according to the liquid chromatograph method, and the ultraviolet absorbance spectrometer was measured to analyze the area of the peak.

2. Titer Analysis Method of Example 2

1 g of Example 2 is precisely weighed and placed in ethanol and dispersed by ultrasonication. 20 mg of the component 19 was precisely weighed and dissolved in ethanol as a standard solution. The above two liquids were tested according to the liquid chromatograph method, and the ultraviolet absorbance photometer was measured to analyze the area of the peak.

division Titer Example 1 Example 2 Comparative Example 3 Analyzed content / Actual content x 100 (%) 100.7% 98.5% 70.3%

As can be seen in Table 2, Examples 1 and 2 are all similar to the actual content contained, it is found that each of the water-soluble crystalline materials are stable to heat even at high temperature mixing of about 80 ℃ and evenly dispersed in the entire lip oil-soluble composition Could.

On the other hand, in Comparative Example 3, the analyzed content was lower than the actual content, and it was found that component 18, which is a water-soluble crystalline substance, was not evenly dispersed in the oil-soluble lip composition. This is because the water-soluble crystalline substance was not evenly dispersed in the contents because the excessive amount of purified water contained the surfactant and the amphiphilic polymer did not sufficiently emulsify the purified water to stabilize the dispersion.

Test Example 2 Dispersibility Evaluation

Example 3, Comparative Example 1 and Comparative Example 2 were analyzed by a micrograph three weeks after the preparation to observe the dispersion or crystal state of each water-soluble crystalline material. The results are shown in FIG. 1, respectively.

As can be seen in Figure 1, compared to the general oil-soluble lip composition (Comparative Example 1) that does not contain a water-soluble crystalline material, the oil-soluble lip cosmetic composition (Example 3) containing a stabilized water-soluble crystalline material The dispersion was good and the water-soluble materials were well crystallized and mixed well. However, in Comparative Example 2, in which too many water-soluble crystalline substances were poor in dispersibility, microscopic photographs also confirmed that recrystallization of the water-soluble crystalline substance occurs and crystals are largely generated.
