In addition, the present invention relates to a poly ethylene glycol-isophthalate-terephthalate (PEIT) composition for impregnating a cosmetic composition into an impregnation member made of a PEIT copolymer and packaging the same in a compact type container to improve user's portability and convenience of use. The present invention relates to a cosmetic comprising an impregnated member made of a copolymer.

In general, a foundation of a color cosmetic composition is a representative color cosmetic material that conceals defects of the skin and exhibits a makeup effect of a natural skin tone. The cosmetic composition may be classified into a powder foundation, a solid foundation, an oily foundation and an emulsion type foundation.

The powder foundation contains more coloring pigments and white pigments than solid ones for beautiful finishing makeup and skin color correction, and coloring pigments and inorganic pigments are blended in different proportions depending on the case. In order to obtain a gloss effect, titanium oxide-based pearl pigment and the like are also used. However, the feeling of use is dry compared to other foundations, it can be clumped by sebum, and the makeup persistence is poor.

A solid foundation uses a sponge with a lot of water. When used as a wet sponge, a hydrophilic surfactant is added to give a creamy texture. When mixed with water, it becomes emulsified. People who prefer to use a refreshing finish because of their freshness and thinness are often used. However, using a sponge that is wet with water can cause skin troubles due to secondary contamination, resulting in poor sebum control ability.

Oily foundation is classified into compact type and stick type, and it is mainly used in winter because of high emollient effect. It spreads well on the skin and is good in adhesion, so it does not get rid of the makeup well and has excellent covering ability, but feeling heavy and frustrating.

In addition, the emulsion type foundation is the most used in the foundation because of the moist feel and the excellent treatment function. The liquid type of the low viscosity gives a feeling of lightness and moist feeling by giving the feeling of lightness and moist feeling.

Although the emulsion type foundation contains the contents in a tube, a pump, and a jar type container, it is difficult to quantitatively discharge the amount desired by the consumer because of low portability, and it has to be applied directly to the skin by hand, .

In addition, since the emulsion type foundation has a very low viscosity, it is difficult to store it in a jar type container, and thus it can not be packed in a compact type container in a compact type container such as a solid foundation or an oil based foundation .

In order to solve such a problem, Korean Patent Registration Nos. 10-1257628 and 10-1355051 disclose a proposed technique. This is because the ultraviolet screening agent of the water-in-oil type is applied to foamed urethane foam of ether polymer or ester polymer type The present invention relates to a cosmetic product impregnated with a foamed urethane foam.

The foamed urethane foam is a polymer having a urethane bond (-NH-COO-) in a polymer chain, and is produced by bonding an isocyanate having a valence of two or more with an active hydrogen compound such as a polyol. The polyol is selected from a polyether polyol or a polyester polyol.

However, the foamed urethane foam using the polyether polyol or the polyester polyol proceeds together with the exothermic reaction, and polyurethane is foamed while generating heat and high-pressure gas. At this time, in the portion where the foamed thickness is thinly formed, And the pressure is applied, the polyurethane gradually inflates and deforms on the inner surface.

Also, the isocyanate is an aromatic isocyanate such as tolulene diisocyanate (MDI) or methylenediphenyl diisocyanate (MDI), which has a quinone imide structure due to ultraviolet rays, resulting in yellowing of the foamed urethane foam.

Further, the foamed urethane foam containing the polyester polyol reacts with an active material such as an ultraviolet barrier cosmetic composition, a silicone oil or highly polar ethylhexyl methoxycinnamate, butylmethoxydibenzoylmethane, etc., and the foamed urethane foam There is a problem that the durability is lowered, such as the phenomenon of swelling or melting and tearing, and the original function is lost.

In addition, if the amount and stability of the contents are uneven or large depending on the pore size of the foamed urethane foam, the storability of the impregnated contents tends to fall off, and if the contents are too small, impregnation is not possible.

If the elasticity of the foamed urethane foam is too high, it is difficult to discharge the contents at a certain pressure when the toilet or the hand is pressed. If the elasticity is too low, excessive contents are discharged.

In addition, amine is used as a catalyst in the production of foamed urethane foam. The amine is mostly volatilized by heat during the production of the foamed urethane foam, but there is a problem that the amine remains unpleasant to some people with sensitive smell.

Korean Patent Laid-Open No. 10-2014-0123028 discloses a foamed foam having an improved feeling of use, which is made of NBR (acrylonitrile-butadiene rubber), SBR (styrene butadiene (Ethylene vinyl acetate), latex, silicone, film type, SIS (Styrene Isoprene Styrene), SEBS (Styrene Ethylene Butylene Styrene), PVA (Polyvinyl Alcohol) A silicone elastomer, a nitrile, a butyl, a polyether, and a neoprene. The present invention also relates to a foamed foam for impregnating a cosmetic composition.

The above-mentioned prior art has a problem that the space for impregnating the cosmetic composition is small due to a small bubble size, so that the cosmetic composition is not easily filled into the space, and even if charging is performed, the expansion rate is high, .

Hereinafter, the present invention will be described in detail.

One embodiment of the present invention comprises an impregnating member 10 made of a poly ethylene glycol-isophthalate-terephthalate (PEIT) copolymer, wherein the impregnating member 10 comprises a cosmetic composition, (Ethylene glycol-isophthalate-terephthalate) copolymer having a hardness of 15 to 40 on the basis of ASKER hardener type F (Type F).

The poly ethylene glycol-isophthalate-terephthalate (PEIT) copolymer is prepared by adding isophthalic acid and te terephthalic acid to ethylene glycol and then using melt polycondensation (Linear oligomer ethylene glycol-isophthalate) and linear oligomer ethylene glycol-terephthalate (linear oligomer ethylene glycol-terephthalic acid) were prepared, and the linear oligomer ethylene glycol-isophthalate Ethylene glycol-isophthalic acid) and a linear oligomer ethylene glycol-terephthalate (linear oligomer ethylene glycol-terephthalic acid) are again melt-polycondensed to prepare a polymer copolymer represented by the following formula (1).

As shown in FIGS. 1 to 4, the impregnating member 10 of the present invention is formed of a non-crystalline fiber structure and has a high porosity. As shown in FIGS. 1 to 4, the impregnated member 10 is made of polyethylene terephthalate (PEIT) It has been confirmed that a large amount of the cosmetic composition can be impregnated into the foamed urethane-impregnated member or the foamed NBR-impregnated member of polyester or polyether type in which conventional bubbles are repeatedly formed.

Further, the impregnating member 10 of the present invention is not formed in a foamed shape but formed in a nonwoven fabric structure, so that the stretchability of the foamed urethane infiltrated member or the foamed NBR impregnated member of the conventional polyester or polyether type is improved, When the member is pressed, all the cosmetic composition remaining in the lower part of the impregnated member can be used by being pressed sufficiently to the lower part of the impregnated member.

The thickness of fibers constituting the impregnating member 10 of the present invention is 20 to 60 탆, preferably 30 to 45 탆, as shown in Fig.

If the thickness of the fibers is less than 20 탆, the voids in the impregnated member are expanded to discharge a large amount of the cosmetic composition, and the tensile strength is weakened. Thus, when the impregnated member is pressed with the makeup tool, If the thickness is more than 60 탆, the voids in the impregnating member are not easily discharged, and the cosmetic composition is not easily discharged. When the impregnating member is pressed down due to low elasticity, the cosmetic composition remaining on the bottom of the impregnating member, There is a problem that is not available at all.

In addition, the conventional polyester or polyether type foamed urethane infiltrated member takes a quinone imide structure by ultraviolet rays, causing a yellowing phenomenon. In the infiltration member 10 of the present invention, the quinone imide structure is not formed by ultraviolet rays Therefore, it has an effect of preventing the yellowing phenomenon.

As shown in FIG. 5, the impregnating member 10 made of the PEIT copolymer of the present invention has a hardness of 15 to 40 on the basis of an ASKER hardness F type (Type F), and has a hardness of 25 to 35 And the hardness means a hardness before the cosmetic composition is impregnated.

If the hardness is less than 15, there is a problem that the impregnating member is too soft and the gel or the liquid cosmetic composition is excessively discharged. When the hardness is more than 40, the impregnating member is hard and the filling of the cosmetic composition is difficult, There is a problem that is not easy.

The impregnating member 10 made of the PEIT copolymer of the present invention has a density of 20 to 25 / / ㎣ and has a space for supporting the cosmetic composition in the impregnated member 10. When the density is within the above range, not only a sufficient space for carrying the cosmetic composition inside the impregnated member 10 is secured, but also the durability is excellent.

If the density of the impregnating member 10 is less than 20 μg / 가, the tensile strength, the elasticity and the hardness are low and the durability is weak. In addition, since the surface tension of the fibers constituted in the impregnating member 10 is low, There is a problem that the impregnation force is decreased and the cosmetic composition is deposited. When it exceeds 25 / / ㎣, the porosity of the impregnating member 10 is low in the whole volume, and the volume to impregnate the cosmetic composition is lowered .

6 to 7, the cosmetic composition of the present invention is impregnated into an impregnated member 10 made of a polyethylene glycol-isophthalate-terephthalate (PEIT) copolymer, and is then packed in a compact type container 100. This is because the compact type container (100) is superior in portability and ease of making as compared with a tube or pump type container, but the flowable cosmetic material is likely to overflow or contaminate the container, The cosmetic composition is impregnated into the impregnated member 10 made of PEIT (poly ethylene glycol-isophthalate-terephthalate) copolymer and incorporated in the compact type container 100. In this case,

12 to 13, the fixture 20 is fitted on the upper side of the impregnation member 10 made of a PEIT copolymer so that the impregnated member 10 is not detached, 20 is characterized in that the screen net 30 is a high frequency bonding or an ultrasonic bonding.

The impregnating member 10 can be prevented from being separated by the fixture 20 and the screen net 30 is not easily dropped due to high frequency bonding or ultrasonic bonding inside the fixture 20, When the screen net 30 is pressed by a tool or a hand, the cosmetic composition is stretched and drained easily from the infiltration member 10.

The screen net 30 is made of polyester fiber and can be made of the same PEIT as the impregnating member 10 and can be made of polyglycolic acid (PGA), polylactic acid (PLA), polycaprolactone (PCL), polyhydroxyalkanoate (PHA) Polybutylene terephthalate (PBT), polytrimethylene terephthalate (PTT), polyethylene naphthalate (PEN), and poly (ethylene terephthalate) You can choose one or more from the group consisting of Vectran.

In detail, as shown in FIGS. 8 to 11, the screen net 30 is made of a polyester fiber, which is a single layer, and the thickness of the polyester fiber is 20 to 25 μm.

The screen net 30 made of the polyester fibers is provided on the upper side of the impregnated member 10 made of a PEIT copolymer impregnated with a gel or liquid cosmetic composition so that the amount of the cosmetic composition discharged from the impregnated member 10 can be adjusted .

If the thickness of the polyester fibers is less than 20 탆, the voids between the polyester fibers are extended to cause an excessive amount of the cosmetic composition to be discharged. When the thickness exceeds 25 탆, the stretchability of the polyester fibers is lowered, There is a problem that not all of the cosmetic composition remaining in the lower part of the impregnation member can be used because it is not pressed sufficiently to the lower part of the member.

14 to 17, the screen net 30 is formed of a urethane foam between polyester fibers, and is formed of a double layer. The screen net 30 is formed of urethane foam, The elasticity and elasticity of the PEIT copolymer can be easily increased and the impregnated member 10 made of the PEIT copolymer can be easily pressed. The cosmetic composition is temporarily stored in the urethane foam so that the amount of the cosmetic composition can be controlled.

In addition, the screen net 30 in which the urethane foam is formed between the polyester fibers has soft touch, so that the cosmetic composition is smoothly applied to the makeup tool or the hand.

In addition, the thickness of the polyester fiber is preferably 20 to 25 탆, as in the other embodiments of the present invention.

Another embodiment of the present invention is characterized in that the screen net 30 is laminated on the top of the impregnating member 10 made of PEIT copolymer.

The laminating means that the impregnating member 10 and the screen net 30 are bonded to each other by adhesive or by heating and welding.

That is, the impregnating member 10 of the present invention and the screen net 30 are bonded by laminating so that the discharge amount of the cosmetic composition discharged from the impregnating member 10 can be adjusted. Layer, or a urethane foam is formed between the polyester fibers as in another embodiment, and is made of a double layer.

In addition, the thickness of the polyester fiber is preferably 20 to 25 占 퐉 as in the other embodiments of the present invention.

The cosmetic composition used in the present invention is not particularly limited as long as it is a composition having a gel phase or a liquid phase. For example, it may be a liquid content of a skin lotion, a skin softener, a skin toner, an astringent, a lotion, a milk lotion, a moisturizing lotion, a nutrition lotion, a massage cream, a nutrition cream, Preferably, it may be an ultraviolet screening agent (sun block) of the formulation.

For example, the cosmetic composition of the present invention may contain an organic UV-blocking agent or an inorganic UV-blocking agent, and preferably has a viscosity of 5,000 to 15,000 cps.

When the viscosity is less than 5,000 cps, the cosmetic composition containing the organic UV blocking agent or the inorganic UV blocking agent is separated from the aqueous phase and the water phase immediately after the preparation and is difficult to be impregnated with a uniform composition when impregnating the infiltrating member. There is a problem that the value as a product is deteriorated due to the sticky and heavy use feeling.

The load at the breaking point was divided by the fracture sectional area of the tensile specimen, The original length of the tensile specimen was subtracted from the total length thus elongated, and the elongation, which is a percentage value obtained by dividing the original length of the tensile specimen, was measured and shown in Table 2.

Comparative Example 1 Comparative Example 2 Example 3 10% caustic soda 75% 88% 98% 10% hydrochloric acid 64% 76% 94% 10% nitric acid 51% 69% 91%

As shown in Table 2, the impregnation members of Example 1 were stable to hydrolysis, but the impregnation members of Comparative Examples 1 and 2 had cracks in the impregnation members due to the hydrolysis reaction, The weakness was confirmed.

&Lt; Test Example 3 > Experiment of preference according to hardness

When the low-viscosity gel-like cosmetic composition is impregnated into an impregnation member made of PEIT (poly ethylene glycol-isophthalate-terephthalate) copolymer and then applied to skin using a makeup tool, The differences in preference according to the hardness of the impregnated members were compared.

In Example 2, a low-viscosity gel cosmetic composition was impregnated with an impregnation member made of a PEIT (poly ethylene glycol-isophthalate-terephthalate) copolymer having a hardness of 10, Example 3 was a low viscosity gel- ethylene glycol-isophthalate-terephthalate) copolymer. In Example 4, the low-viscosity gel cosmetic composition was impregnated with an impregnation member made of PEIT (poly ethylene glycol-isophthalate-terephthalate) copolymer having a hardness of 50 will be.

The above Examples 2 to 4 were cremated for 50 days for women in their 20s and 30s for 7 days, and the use results were compared and evaluated. The preference according to the hardness of the impregnation member composed of PEIT (poly ethylene glycol-isophthalate-terephthalate) copolymer was evaluated by a sensory evaluation (5 point scaling method), and it was evaluated as excellent 5 points, good 4 points, Poor 2 points, and very poor 1 point. The evaluation scores are shown in Table 3 below.
