Description

Cosmetic composition containing adipic acid neophentyl glicol crosspolymer suspension solution for covering the skin pores

The present invention relates to a cosmetic composition for W / O type or O / W type pore cover containing adipic acid / neopentyl glycol crosspolymer suspension solution. The adipic acid / neopentyl glycol crosspolymer suspension solution is W / O type or O / containing adipic acid / neopentyl glycol crosspolymer suspension solution, characterized in that 10.0 to 30.0% by weight relative to the total weight of the cosmetic composition It relates to the cosmetic composition for W type pore cover.

The pores are literally holes where hairs come out, and the oily glands called sebaceous glands are attached to the root of the hair, and the sebum produced here is secreted into the skin through the pores. Normally, pores begin to grow in their late 20s, which become more noticeable as the skin ages and becomes dry and elastic.

The widening of pores may include the above-mentioned excessive sebum secretion, skin aging and stagnant waste in the pores. After puberty, menstruation begins in men and metamorphosis in men, and the distinction between men and women is clearly distinguished, and the effects of hormones increase sebum production and the pores corresponding to the passage of the secretion of sebum to the skin surface are widened.

If sebum is normally produced and discharged well, no problem occurs, but the pores are naturally widened in order to escape the large amount of sebum in the limited space. In addition, those with sebaceous glands that are constitutionally producing sebum are two to three times larger than normal or more sensitive to hormones that promote sebum secretion. Will have However, even if the sebum secretion is not much, as one grows to some extent pores. Women's skin elasticity begins to drop sharply around 30 years of age, resulting in more skin and more pores. The lack of elasticity of the skin is due to a decrease in the elasticity of the epidermal cells constituting the outer layer of the skin and the collagen constituting the deep dermis of the skin.

When the skin's elasticity is reduced, the pores increase because the force that tightens the passage of sebum is reduced. In addition, wastes stagnated in the pores may also cause pores to be widened, which should be removed cleanly after using color cosmetics with excellent coverage. Otherwise, pores may be clogged by body pigments and colorants, causing skin problems and pores to widen. Cause. In this case, even after using the basic cosmetics, even after using the color cosmetics, the skin appearance by the pores is exposed as it is, making it difficult to be transparent and natural makeup.

Interest in conventional pore cosmetics and sales volume of products continues to grow, and related research and development is also actively progressing. Currently, active research is being carried out using basic extracts (KR 10-2006-0014890) and natural polymer polymers, which have excellent pore shrinkage effect, but this gives a contraction function rather than pore cover function. have. In this case, it is necessary to continuously use it for a long time, and the effect is greatly changed depending on the content of the shrinkage component.

On the other hand, in color cosmetics, white pigments such as titanium dioxide, which has a high refractive index and high reflectivity to cover skin defects such as freckles, blemishes, blemishes, and pores, and express skin color beautifully, and polymethyl methacrylate having high reflectance and transmitted light diffusion , Nylon powder, silica and the like were used (KOBO, Japan).

However, white pigments have excellent pores and skin flaw cover, but if the components are left intact without being adsorbed in the pores, it becomes one cause of skin troubles as mentioned above, polymethylmethacrylate, Nylon, silica, etc. must be contained in a large amount in the formulation to show the pore cover function. In this case, the moisturizing effect is reduced and the skin feels dry and may cause skin diseases.

As mentioned above, research and development on the pore cover has been steadily progressed, when titanium dioxide having a refractive index of less than 1.30 to 1.50 and a metal oxide having a mixture of 1.45 to 1.85 (JP 2003-63933) are derived from acrylic acid. We are researching and developing various ingredients and formulations, such as the case of increasing the viscosity using the formulated Carboxylic Acid Polymer and making the formulation with less spreading and bleeding (UP 05,997,887). However, when the powder having a high refractive index is used, the pore covering effect is excellent, but skin irritation or trouble may occur due to clogging of pores. In addition, in case of using Carboxylic Acid Polymer derived from Acrylic Acid, the effect will be different depending on the content used, and if it is contained in a large amount, it may show a sticky feeling.

On the other hand, silicone elastomers can be cited as components that exhibit excellent pore coverage and exhibit effects such as spreadability and good usability. Currently, it is one of the most used raw materials for Japanese and domestic cosmetics manufacturers, and it is a high molecular weight cross-linkable silicone powder that gives excellent spreadability and soft feeling when applied to cosmetics (KOSE, Japan). Such silicone elastomers have excellent compatibility in prescriptions composed of silicone as a main component, but have low compatibility in prescriptions composed of other main components, and have a disadvantage in that they are difficult to disperse, mix, and emulsify when contained in large amounts.

The prior art related to the present invention is Korean Patent Registration 10-0611884 (cosmetic composition with excellent pore reduction effect) selected from among asiatic acid, asiaticoside and madecaic acid widely used as wrinkle improvement or wound healing agent in cosmetics and external skin preparations A cosmetic composition capable of restoring the pore size or preventing the pore size from being increased by restoring the structure of the indented pores containing one or more kinds of alpha hydroxy acids or salts thereof widely used as an exfoliant in cosmetics. It is about.

In addition, Korea Patent Registration 10-0127337 (method of producing adipic acid) to hydrate cyclohexene oxide to prepare 1,2-dihydroxycyclohexane and oligomo, and then oligomer, 1,2-dihydroxycyclohexane, And a process for producing adipic acid of industrial value, which is prepared in terms of yield by oxidizing a mixture containing cyclohexene oxide in an aqueous solution of nitric acid. However, these prior art is different from the present invention in the technical configuration.

Pore cover cosmetics having a soft focus effect have been widely used in recent years in that skin tone is soft and natural. However, the cosmetics for pore cover containing the powder and the composite powder excellent in the soft focus effect has a disadvantage that the skin moisturizes low.

On the other hand, a silicone elastomer is a component that has excellent pore coverage and can exhibit effects such as spreadability and good usability. Currently, it is one of the most used raw materials for Japanese and domestic cosmetics manufacturers, and it is a high molecular weight cross-linkable silicone powder that gives excellent spreadability and soft feeling when applied to cosmetics (KOSE, Japan). Such silicone elastomers have excellent compatibility in prescriptions composed of silicone as a main component, but have low compatibility in prescriptions composed of other main components, and have a disadvantage in that they are difficult to disperse, mix, and emulsify when contained in large amounts.

Overcoming these shortcomings, adipic acid / neopentyl is a crosspolymer of polyesters and polyols crosslinked with polyesters and polyols, which are excellent in spreading and usability compared to silicone elastomers, excellent compatibility with silicone and other components, and convenient in the formulation process. Studies using glycol crosspolymers are being made (US 2007/02443220). This crosspolymer is a soft white powder with an average particle diameter of 3-15 microns and is currently sold by Dermatech under the trade name Dermatech Silester Powder or Siloxy Polyester Powder. However, the appearance of powder is excellent in spreadability when applied to the foundation and color cosmetics, but has a disadvantage in that the adhesion and adhesion is not good, causing the dry skin of the skin and also affect the formulation stability.

In order to solve the above problems, in the present invention, a suspension solution (Aurasphere N, manufactured by DIOW Products, Inc.) was used using adipic acid / neopentyl glycol crosspolymer.

This solution is adipic acid / neopentyl glycol crosspolymer, purified water and amodimethicone, dimethicone silicones and hydroxypropyl methylcellulose, V / V copolymer, phenoxyethanol, capryl glycol, clofenesin And the like. This solution can be easily applied to O / W (Oil in water) or W / O (Water in Oil) cosmetic compositions in liquid form, and the pore covering effect is not required even if the powder used to show the existing pore covering effect is used. Excellent and moisturizing.

The cosmetics for pore cover using adipic acid / neopentylglycol crosspolymer can maximize the skin's moisturizing effect without causing dryness of the skin as well as pore covering effect, and can also produce a soft feeling and natural skin tone. It provides a cosmetic composition for covering the pores.

Through the cosmetic composition containing the adipic acid / neopentyl glycol crosspolymer suspension solution of the present invention, overcoming the drying of the skin due to the low moisturizing power, which is a disadvantage of the cosmetic for pore cover with a soft focus effect with a pore cover effect, It can have an excellent moisturizing and lasting effect. Furthermore, by containing the solution there is a beneficial effect on the appearance of natural skin tone, soft feeling, fluidity and refreshing feeling of the formulation.

The present invention relates to a cosmetic composition for covering pores of O / W (Oil in water) or W / O (Water in Oil) type containing a suspension solution containing adipic acid / neopentyl glycol crosspolymer.

Preferably the adipic acid / neopentyl glycol crosspolymer suspension solution is characterized in that 10.0 to 30.0% by weight based on the total weight of the cosmetic composition.

If the adipic acid / neopentyl glycol crosspolymer suspension solution is more than 30% by weight, the content of the polymer in the solution is good because the pore covering effect is good, but has a disadvantage in that it is difficult to mix and emulsify the light feeling and the desired formulation and manufacturing process. On the other hand, when the adipic acid / neopentyl glycol crosspolymer suspension solution is less than 10% by weight, it is difficult to expect a pore cover effect.

In addition, the adipic acid / neopentyl glycol crosspolymer has an average particle diameter of 3 to 15, and the suspension solution is characterized by no change in physical properties such as precipitation phenomenon and phase separation phenomenon over time.

The adipic acid / neopentylglycol crosspolymer suspension solution used in the present invention is a polymer obtained by cross-linking organic dicarboxylic acid adipic acid and polyol neopentylglycol. Arosphere N, manufactured by DIOW Products, Inc., prepared by mixing oxypropyl methylcellulose, V / V copolymer, phenoxyethanol, capryl glycol and clofenesin to have semi-Cream type properties. Has

The adipic acid / neopentyl glycol crosspolymer suspension solution is very compatible with silicone components, ester oils and vegetable oils, and has excellent pore covering effect.

This is to compensate for the drawback of causing skin dryness of adipic acid / neopentylglycol crosspolymer in application to the formulation.

Adipic acid in the adipic acid / neopentyl glycol crosspolymer used in the present invention is an organic dicarboxylic acid, which is mainly used as a precursor for making nylon in the form of white powder, and is mainly used as a pH adjusting agent in cosmetics, which can sometimes be obtained in nature. It has the structure of [FIG. 1].

In addition, neopentyl glycol is used in cosmetics as a film forming agent to play a role of always moisturizing and adhesion feeling, has a structure of [Fig. 2].

In the present invention, in order to apply the above properties of adipic acid and neopentyl glycol to the cosmetic composition for O / W (Oil in water) type or W / O (Water in Oil) type pore cover, adipic acid and neopentyl glycol Amodimethicone which is excellent in skin adhesiveness to a crosslinked polymer as a cationic surfactant; Hydroxypropyl methyl cellulose which is an emulsion stabilizer having excellent skin spreadability as a water-soluble thickener; And a suspension solution in which a VP / V copolymer was mixed and mixed as a water-soluble film former.

In addition, to prepare a cosmetic composition for O / W (Oil in water) and W / O (Water in Oil) type pores cover containing adipic acid / neopentyl glycol crosspolymer according to the present invention Maximizes pore coverage with pentylglycol crosspolymer suspension solutions, and uses polyol moisturizers such as dipropylene glycol to provide moisturizing, long lasting, and refreshing effects that are disadvantages of water in oil formulations Silicone oil, silicone gel, water soluble thickener, and the like were mixed.

First, the constituents and composition ratios of the W / O (Water in Oil) type pore cover cosmetic composition are 40 to 50% by weight of purified water, 10 to 30% by weight of adipic acid / neopentyl glycol crosspolymer suspension solution, and 5 to 10 glycerin It is preferable that they are 5 weight%, butylene glycol 5-10 weight%, silicone oil 5-10 weight%, surfactant 1-3 weight%, silicone gel 20-30 weight%, and film forming agent 0.5-1.0 weight%. .

And constituents and composition ratio of the cosmetic composition for O / W (Oil in water) type pore cover is 60 to 80% by weight purified water, 10 to 30% by weight adipic acid / neopentyl glycol crosspolymer suspension solution, 0.5 to water-soluble thickener It is preferably 1.5% by weight, 1 to 5% by weight glycerin, 1 to 5% by weight butylene glycol, 1 to 3% by weight surfactant, 1 to 5% by weight silicone gel and 0.5 to 1.0% by weight film-forming agent.

The formulation process of the above embodiment emulsifies the oil phase (cyclomethicone, silicone gel, surfactant, film former, tocopheryl acetate) and the aqueous phase (purified water, preservative, butylene glycol, glycerin) using an emulsifier, Adipic acid / neopentylglycol cross-polymer suspension solution and powder (nylon powder, polymethacrylate, talc / polymethylmethacrylate) were prepared by post-treatment.

Experimental Example 1 Pore Cover Effect Measurement

The pore cover effect was measured using the cosmetics for pore cover prepared in Examples 1 to 4 and Comparative Examples 1 to 4. The cosmetics were applied to the face of 10 healthy women and 10 men, and then the pore area before and after application using Skin Analysis (Facial Stage DM-3 Manager, Co., Ltd. true system) as shown below. m ² ) and number were measured, and the results are shown in FIG. 4.

As shown in FIG. 4, it was found that the pore covering effect of Example 4 was the best in the water in oil (W / O) formulation, and the pore covering effect was also excellent in Examples 1 to 3.

In addition, in the case of Comparative Example 3, when only a large amount of adipic acid / neopentyl glycol crosspolymer suspension solution is mixed with a powder having excellent soft focus and Comparative Example 2 and a powder having excellent soft focus The pore cover effect was found to be superior to that of Comparative Example 4.

However, in the case of Comparative Example 3 had a disadvantage of difficulty in mixing and emulsifying in the manufacturing process.

FIG. 5 shows the pore area after skin application in O / W (Oil in Water) formulations. In this case, Comparative Examples 6 to 8, which contain adipic acid / neopentyl glycol crosspolymer suspension solution, contain powder having excellent soft focus or are mixed with adipic acid / neopentyl glycol crosspolymer suspension solution. Compared with Comparative Example 7 and Comparative Example 8 and the pore cover effect was found to be excellent.

Experimental Example 2 Moisturizing Effect Measurement

The moisturizing effect was confirmed using the cosmetics for pore cover prepared in Examples 1 to 4 and Comparative Examples 1 to 4.

The cosmetics were applied to the face twice a day for 25 healthy women (average age 28 years) in the room with temperature 22-24 ℃, relative humidity 55%, no air flow and SKICON-200 (Skincon) 200, IBS CO LTD, Japan) to measure the moisture content of the skin before and after application to determine the degree of moisturizing effect. The results are shown in [Table 3].

As can be seen from the results of Table 3, in the W / O (Water in Oil) formulation, the moisture content of the skin was most improved in the case of Example 3 and Comparative Example 3.

However, unlike Example 3, Comparative Example 3 had a disadvantage of difficulty in mixing and emulsifying the formulation.

On the other hand, in the case of Example 1, Example 2, and Example 4, it was found that the effect of improving the skin moisture content was less than that of Example 3.

In the case of Example 1, Example 2, and Example 4, unlike the case of Comparative Example 3, it was possible to easily create the desired formulation without difficulty in the manufacturing process during the formulation experiment.

In addition, in Comparative Example 2 and Comparative Example 4, as shown in the <Experimental Example 1> had a pore cover effect, it was found that the skin moisture content was not significantly improved.

This may be because dryness is caused by the sebum absorption ability of nylon powder and polymethacrylate.

In the O / W (Oil in Water) formulation, Comparative Examples 5 to 8, which include the adipic acid / neopentylglycol crosspolymer suspension solution as shown in Table 4, do not. Compared with Comparative Example 8, it was found that the overall skin moisture content was greatly improved.
