Description

Non-sticky and Photo-stable Hydrophilic Transparent Gelling Type Skin-Lotion Composition}

The present invention relates to a water-soluble transparent gel-like cosmetic composition having no stickiness and excellent light stability. More specifically, the present invention contains carbomer 940, methylglucose-20, disodium idieti and benzophenone-5 in a fixed ratio, thereby preventing stickiness by methylglucose-20 and disodium diantiide. It relates to a water-soluble transparent gel-like cosmetic composition characterized by excellent light stability by A and benzophenone-5.

Conventional reported patents and literatures introduce various gel formulations such as water soluble gels, silicone gels, and solid gels, but these gel phases have many disadvantages such as stickiness, oiliness, and slippery in terms of usability. In particular, in preparing the cosmetic water of the water-soluble transparent gel, it is very difficult to remove the stickiness without containing silicone oil or powder.

On the other hand, the conventional water-soluble gel-like cosmetics are composed mostly of water-soluble polymers such as carbomer (carboxy vinyl polymer), sodium carboxymethyl cellulose, etc., these have a problem that the feeling of use is sticky (Domestic Patent Publication No. 2001-0030462, Cosmetic Sciencd and Technology Series / Voume 10). In particular, as a moisturizer commonly used in cosmetics, polyhydric alcohols such as glycerin, propylene glycol, 1,3-butylene glycol, sorbitol, and sodium hyaluronate by microbial fermentation methods are mainly used. There is a limit to getting a fresh feeling. Therefore, in order to compensate for these drawbacks, cosmetics are being developed that disperse silicone oil or silicone polymers in water-soluble gel cosmetics or add powders such as talc to supplement the finish feeling. U.S. Patent No. 5,626,853 introduces a make-up gel prepared by mixing a silicone polymer using carbomer (carboxyvinyl polymer), carboxymethyl cellulose sodium, or the like as a water-soluble polymer. U.S. Patent No. 5,380,528 introduces cosmetics containing water-soluble polymers, humectants, silicone oils, silicone polymers and fluorine-based silicones. U. S. Patent No. 6,153, 204 also describes formulations using water soluble sugar derivatives. Korean Patent Laid-Open No. 1999-009252 also introduces citric acid to stabilize dimethicone, a useful moisturizing ingredient added to prevent stickiness in cosmetic compositions on transparent gels. However, all of the above-described methods have problems such as complicated processes such as the use of many surfactants to stably emulsify and disperse the silicone oil, the silicone polymer and the powder during manufacture, and the problem that the viscosity of the formulation itself decreases.

In addition, the chamomer in the water-soluble polymer is a problem of lowering the viscosity due to light, especially in the composition of the water-soluble gel-like lotion, but studies on this have been insufficient. In order to compensate for this problem, U.S. Patent No. 5,891,903 has an example in which melantoin or its analog is added to a water-soluble gel cosmetic, but its effect is not excellent.

Although various efforts have been made by the inventors to improve the stickiness and light stability problems of water-soluble gel cosmetics, the complex process for the stability of the formulation by the addition of oil and powder, the problem of the viscosity decrease of the formulation itself, and the light stability of the formulation I have a difficulty.

Thus, the present inventors conducted an intensive study to develop a water-soluble transparent gel-like lotion that is easy to manufacture, has no stickiness in use, and prevents viscosity decrease even when irradiated with ultraviolet rays. The present invention has been accomplished by the discovery that methylgluses-20, disodium ideti and benzophenone-5 can be achieved.

The present invention relates to 0.05 to 2% by weight, preferably 0.1 to 1% by weight of carbomer 940 as water-soluble polymer, 0.5 to 8% by weight of methylgluses-20, preferably 1 to 4% by weight of anti-sticking and moisturizing agent. Non-sticky and excellent light stability, characterized in that it contains trisodium ideti and benzophenone-5 for light stability, respectively, 0.5 to 5% by weight, preferably 1 to 3% by weight of carbomer The present invention relates to a water-soluble transparent gel-like lotion composition.

Carbomer 940 used in the present invention is a product of Goodrich (BF Goodrich), the molecular weight of about 4,000,000, the brand name is Carbopol 940 and when used with a gelling agent shows an excellent incremental effect even at low concentrations. If it is used less than 0.1% by weight it is made of a low viscosity lotion and difficult to gel, and when used in excess of 4% by weight, the viscosity is very high, its use as a lotion is not very good.

Hereinafter, the present invention will be described in more detail with reference to Examples, but the technical scope of the present invention is not limited in any way by these Examples.

Examples 1-4 and Comparative Examples 1-2

Next, using the compositions of Table 1, Examples 1 to 4 and Comparative Examples 1 to 2 were prepared as follows. First, ethanol, preservatives and fragrances are mixed and dissolved in a solution obtained by mixing and dispersing purified water, chamomer, methylgluses-20, trisodium ideti and benzophenone-5, followed by mixing triethanol amine Water-soluble transparent gel-like lotion composition was prepared by neutralization by injecting and completely defoaming. Each raw material used at this time was used in the ratio as shown in Table 1.

The water-soluble transparent gel-like cosmetic composition prepared above was subjected to sensory evaluation and light stability test for stickiness and freshness.

Experimental Example 1: sensory test for stickiness and freshness

After 45 panels of 20 to 40 years in a constant temperature and humidity room (27 ℃, 70% relative humidity conditions) for about 15 minutes, the water-soluble transparent gel-like lotion composition prepared above was pumped 5 times to a certain amount 1g, that is, a pump container After spreading evenly on both cheeks was carried out by the sensory evaluation of the degree of stickiness and freshness are shown in Table 2 below. The evaluation method of stickiness and freshness was averaged by taking a form referring to the following scores.

Sample Name Stickiness Freshness Example 1 2.76 3.42 Example 2 3.51 3.44 Example 3 3.62 2.93 Example 4 3.71 1.33 Comparative Example 1 0.53 3.69

As can be seen from the results of Table 2, as a result of performing the sensory evaluation, the gel lotion of Examples 1 to 4 according to the present invention can be seen that the degree of stickiness is significantly reduced than the gel lotion of Comparative Example 1, methylgluses The higher the weight percentage of -20, the smaller the degree of stickiness. However, the content of 8% by weight is not fresh. Therefore, methylgluses-20 is preferably prescribed in the range 1.0 to 4.0% by weight.

Experimental Example 2: Light Stability Test

Each of the prepared water-soluble transparent gel-like lotion composition contained a predetermined amount of 100g in a 120g constant container, and irradiated with ultraviolet rays and daylight for each hour, and then stored at 25 ° C. for 1 day, and then the viscosity was measured and the results are shown in Tables 3 and 4 below. . Viscosity is an average of five measurements of each sample for 1 minute under the condition of SPINDLE # 4 at 30 rpm in a Brookfield DV-E VISCOMETER.

As can be seen from the results of Tables 3 and 4, the gel lotion of Examples 1 to 4 according to the present invention almost no viscosity decrease compared to the gel lotion of Comparative Example 2 as a result of performing the ultraviolet and daylight test over time Able to know. It can be seen that trisodium ideti and benzophenone-5 are effective in stabilizing the gel phase by absorbing ultraviolet rays and sunlight.
