In recent years, the requirements of customers have become increasingly diverse and subdivided, and the quality of products has become a prerequisite. Differentiated products such as unique appearance, multi-function and trendy items suitable for the trend of the times are attracting attention. For example, in today's hard-to-compete products, a multi-in-one product that functions as a single product may have a side effect, such as a functional aspect and a shortening of make-up time, And packs and masks have attracted attention with their unique features such as grocery items that are easily accessible in everyday life or with interesting ways to use them. In addition, whitening, anti-wrinkle, sunscreen (Sunscreen) is increasing in importance as the interest in photoaging as well as natural aging, and the demand for such functional cosmetics continues to increase regardless of age. This effective functional cosmetics contain a variety of active ingredients, which is an important factor causing rheological fluctuations of the cosmetic formulation, and since it is directly connected to the stability of the product, the stabilization technology of the active ingredient in the formulation was required.

Many types of viscosity modifiers have been used in cosmetics and personal care products from the past. However, the existing viscosity modifiers are very rapidly reduced in viscosity control ability under various salt and pH conditions, and could not give normal emulsion stability and thickening effect.

In addition, recently, cosmetics have been made into a variety of active substances or product development at various pH has been made. However, since various salts are present in these various active substances, the viscosity of the viscosity modifier described above was impaired, resulting in difficulty in developing various products and stability problems.

Advantages and features of the present invention and methods of achieving them will become apparent with reference to the embodiments described in detail below. The present invention may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Is provided to fully convey the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification may be used in a sense that can be commonly understood by those skilled in the art. Also, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

Hereinafter, a composition having viscosity stabilizing properties according to an embodiment of the present invention will be described.

The composition having a viscosity stabilizing property according to an embodiment of the present invention may include a first thickener, a second thickener, a chelating agent, a discoloration inhibitor, and purified water represented by the following Chemical Formula 1.

Formula 1

Where X is an integer from 1 to 10,000.

Formula 1 is a sodium polyacrylate polymer. Sodium polyacrylate polymer is a thickener having excellent salt stability. In addition, as a water-soluble thickener, it can be dispersed in the form of droplets (droplet) in purified water as shown in FIG. At this time, an electrostatic repulsive force may be applied between the droplets of the sodium polyacrylate polymer dispersed in purified water, and thus an excellent incremental effect may be expected.

On the other hand, the sodium polyacrylate polymer of the general formula (1) has a relatively high charge density. More specifically, the sodium polyacrylate polymer of Formula 1 may have a charge density of 2.0 meq / g, preferably has a charge density of 3.7 meq / g. Sodium polyacrylate polymer has a relatively high charge density, it can have a relatively strong electrostatic repulsive force when dispersed in purified water in the form of droplets.

On the other hand, the first thickener represented by the formula (1) is preferably contained in 0.01 to 3.0% by weight relative to the total weight of the composition having a viscosity stabilizing properties. If the content of the first thickener is less than 0.01% by weight, the composition may not increase in temperature and the high temperature stability may be deteriorated. If the content of the first thickener is used in excess of 3.0% by weight, a satisfactory feeling may be obtained such as stiffness and stickiness when applying the skin. It is difficult and not suitable as a composition.

Next, a second thickener may be used to improve the thickening properties of the composition and to promote stability of the formulation. In other words, the second thickener, together with the first thickener, can contribute to the stability of the formulation of the composition.

The second thickener is carbomer, carboxyvinyl polymer, acrylates / alkyl acrylate crosspolymer of 10 to 30 carbon atoms, carboxymethyl cellulose, hydroxyethyl cellulose, polyacrylamide, hydroxyethyl acrylate / sodium It may be at least one selected from the group consisting of acryloyl dimethyl taurate copolymer, glyceryl polymethacrylate, xanthan gum, sodium magnesium silicate, cellulose and magnesium aluminum silicate.

On the other hand, the second thickener is preferably contained in 0.01 to 3.0% by weight relative to the total weight of the composition having a viscosity stabilizing properties. If the content of the second thickener is less than 0.01% by weight, there is a possibility that the composition is not formed and high temperature stability may be deteriorated, and when used in excess of 3.0% by weight, a satisfactory feeling such as stiffness and stickiness may be obtained when applying the skin. It is difficult and not suitable as a composition.

On the other hand, the composition having a viscosity stability according to an embodiment of the present invention is composed of a combination of polymers having an increasing effect, it is possible to stabilize the additives and active ingredients to be added to the composition. That is, by combining polymers having an increasing effect, the formulations are stably trapped in the formulations to minimize the rheological variance of the formulations, to help stabilize the formulations, and to effectively reduce wrinkles, whitening, anti-inflammatory, and UV rays. To facilitate delivery of the drug. For example, a chelating agent capable of removing metal ions and a discoloration preventing agent that blocks the ultraviolet rays and protects the finished product from chemical and physical changes caused by the ultraviolet rays may be basic elements of the cosmetic composition. However, these additives contain excess metal ions and, when added into the formulation, may cause a decrease in viscosity of the formulation. That is, it may be a major cause of rheological fluctuations. This is a part directly related to the stability of cosmetics.

According to the present invention, since it is composed of a combination of polymers having an increasing effect, it provides a high viscosity that can contribute to the stability of the formulation, it is possible to minimize the rheological variation of the formulation, providing a relatively improved formulation Can be.

Next, the composition having a viscosity stabilizing property according to an embodiment of the present invention may include a chelating agent.

Chelating agent is a component for inhibiting re-deposition of the coloring material to the skin surface by chelating metal ions (typically calcium ions) that serve as a linkage of the coloring material to the skin surface. It can also prevent the oxidation of vitamin C, which nourish the skin.

Pyrophosphate salt or ethylenediaminetetraacetic acid (EDTA) of Formula 2 may be used as the chelating agent.

(2)

Here, the pyrophosphate salt may be at least one selected from the group consisting of tetra alkali metal pyrophosphate, dialkali metal diacid pyrophosphate and trialkali metal monopyrophosphate.

On the other hand, the chelating agent is preferably contained in 0.01 to 0.7% by weight relative to the total weight of the composition having a viscosity stabilizing properties. When the content of the chelating agent is less than 0.01% by weight, the chelating ability of the metal ions is too low, and there is no effect of inhibiting the redeposition of the substantially colored material. If the content of the chelating agent exceeds 0.7% by weight, it may not be suitable for use on the skin due to the chelating agent's peculiar aroma and irritation.

Next, the composition having a viscosity stabilizing property according to an embodiment of the present invention may include a discoloration preventing agent.

The anti-tarnish agent may block ultraviolet rays that may be directly directed to the composition from sunlight, thereby preventing the composition from being chemically or physically changed by the ultraviolet rays.

As a representative discoloration inhibitor can be used a benzophenone compound of the formula (3).

That is, the discoloration inhibitor may be at least one selected from the group consisting of benzophenone-3, benzophenone-4 and benzophenone-9.

On the other hand, the discoloration inhibitor is preferably contained in 0.01 to 0.5% by weight relative to the total weight of the composition having a viscosity stabilizing properties. If the content of the color change inhibitor is less than 0.01% by weight, the sunscreen effect by the color change inhibitor may not be sufficiently expected. When the content of the anti-tarnish agent exceeds 0.5% by weight, the anti-tarnish agent may not be preferable from an economical point of view because the effect of blocking ultraviolet rays is no longer increased.

Next, purified water may be used to mix the first thickener, the second thickener, the chelating agent and the discoloration agent described above.

On the other hand, the composition having a viscosity stabilizing property according to an embodiment of the present invention can be used, for example, in the ultraviolet absorber or blocker. In this case, an ultraviolet absorber or blocker component may be further included in the composition.

Examples of the ultraviolet absorbent component include cinnamate derivatives such as octyl methoxycinnamate and isoamyl-p-methoxycinnamate; Salicylic acid derivatives such as butylmethoxy dibenzoylmethane, bisethylhexyloxyl phenolmethoxy phenyl triazine and octyl salicylate; PABA (p-aminobenzoic acid) derivatives, benzophenones and anthranilates.

In addition, the ultraviolet acid blocker components include ZnO (zinc oxide), TiO ₂ (titanium dioxide), silicates, talc and the like.

The content of the ultraviolet absorber or the blocking agent may be 5.0% by weight to 10.0% by weight based on the total weight of the composition. If the content of the ultraviolet absorber or the blocking agent is less than 5.0% by weight, the ultraviolet absorbing or blocking effect may not be sufficient, and if it exceeds 10.0% by weight, it is difficult to formulate the composition and the clouding phenomenon appears severely in use.

In the above, the composition having a viscosity stabilizing property according to an embodiment of the present invention is used for the ultraviolet absorber or the blocking agent, but the composition is not limited to the use.

More specifically, the composition having a viscosity stabilizing property according to an embodiment of the present invention can be used in all kinds of cosmetics and is not particularly limited in the formulation, for example, sunscreen soft water, lotion, cream, essence In addition to cosmetic compositions for the purpose of sun protection, such as sprays, general softening cream, astringent makeup, nourishing cream, nourishing cream, massage cream, eye cream, eye essence, essence, cleansing cream, cleansing lotion, cleansing Formulations of foams, cleansing water, packs, powders, body lotions, body creams, body essences, body cleansers, hair dyes, shampoos, rinses, toothpastes, mouthwashes, hairdressing agents, wool, lotions, ointments, gels, creams, patches or sprays Can have

Experimental Example 1 Viscosity Reduction Rate Evaluation

The viscosity value measured at the time of containing only a thickener component and the other active ingredient other than a thickener was measured by comparing the viscosity value measured by the 1st and the viscosity value measured by the 2nd. The results are shown in Table 2 below.

Example 1 Example 2 Example 3 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Viscosity Reduction (%) 5.7 2.8 4.1 15.6 29.5 1.2 2.2

As can be seen from Table 2, the viscosity reduction rate was smaller than that of Comparative Examples 1 and 2 even if other active ingredients were added to the formulation in which the thickener was dispersed. However, Comparative Examples 3 and 4, in which the amount of the first thickener was large, had a small decrease in viscosity, but showed poor results in the feeling evaluation described later.
