일반적으로, 점도가 낮은 액상 유화 제형 화장료는 발림성 및 퍼짐성이 우수하고 사용감이 우수하다는 점에서 선호되고 있으나, 휴대가 불편하고, 저장시에 분리가 일어나는 등 안정성에 있어서 문제가 있었다. 이러한 문제점을 해결하기 위한 한 방안으로서, 저점도 유화 제형인 액상 화장료를 폴리우레탄 폼에 함침시킨 화장품 제품들이 개발되어 사용되어 왔다. In general, low viscosity liquid emulsion formulation cosmetics are preferred in terms of excellent spreadability and spreadability and excellent use, but there is a problem in stability, such as inconvenient to carry, separation occurs during storage. As a way to solve this problem, cosmetic products impregnated with a polyurethane foam liquid cosmetics, a low viscosity emulsion formulation has been developed and used.
폴리우레탄 폼은 폴리우레탄의 안정성이 우수하다는 장점과 폴리우레탄 폼 내에 많은 양의 화장료를 함침시키기에 유리하다는 장점이 있으나, 이의 기공이 너무 크기 때문에 화장료를 기공 전반에 걸쳐서 고른 분포로 유지하지 못하고, 지속적 사용에 따라 폼에 일정한 압력이 지속적으로 가해질 경우에는 함침된 화장료가 폼의 하부에 침강하는 등 저장성에 있어서 문제점이 있었다. 따라서, 원래 형태를 유지하면서 함침된 화장료를 끝까지 사용하기 어려우며, 하부에 침강된 화장료를 사용하기 위하여 화장품을 어느 정도 사용한 후 소비자가 직접 함침용 스폰지를 다시 뒤집어서 사용해야 하는 등 불편한 문제점이 있었다. 이에, 지속적인 사용에 의해서도 화장료를 고르게 유지할 수 있는 다공성 폼이 요구되고 있는 실정이다.Polyurethane foam has the advantage of excellent stability of the polyurethane and the advantage of impregnating a large amount of cosmetics in the polyurethane foam, but because its pores are so large that the cosmetics do not maintain an even distribution throughout the pores, When a constant pressure is continuously applied to the foam according to the continuous use, impregnated cosmetics have a problem in storage properties such as settling in the lower portion of the foam. Therefore, it is difficult to use the impregnated cosmetics to the end while maintaining the original form, and after using the cosmetics to some extent to use the cosmetics settled in the lower part, the consumer has to invert the impregnated sponge and use it again. Therefore, the situation is required a porous foam that can maintain the cosmetic evenly by continuous use.
또한, 화장료 중에 함유되는 성분들인 실리콘 오일이나 극성이 높은 에칠헥실메톡시신나메이트, 에칠헥실살리실레이트 같은 물질과 반응하여 폼이 팽창되거나 녹아서 찢어지는 현상 등과 같은 내구성의 저하도 해결되어야 할 문제점들이다. In addition, the degradation of durability, such as foam expansion or melting and tearing due to reaction with a component such as silicone oil, highly ethoxyhexylmethoxycinnamate, and ethoxyhexyl salicylate, which are contained in cosmetics, are also problems to be solved. .

바람직하게는, 상기 다공성 폼은 아크릴로니트릴부타디엔 고무(NBR)와 스티렌-부타디엔 고무(SBR)의 블렌드를 발포시켜 제조될 수 있다. 이러한 NBR 및 SBR를 함유하는 중합체 블렌드로 제조된 다공성 폼은, 기존의 폴리우레탄 다공성 폼에 비해 중합체의 소수성이 크므로, 내용물 보존성이 더 우수할 수 있다. 이는 폼 내부에 액상의 화장료가 충진된 후에는 소수성 중합체가 화장료의 액체 성분을 확산시키지 않아 기공을 거쳐 다공성 폼 외부로 빠져나가지 않기 때문이다.Preferably, the porous foam may be prepared by foaming a blend of acrylonitrile butadiene rubber (NBR) and styrene-butadiene rubber (SBR). Porous foams made of polymer blends containing such NBR and SBR may have better content retention because of the greater hydrophobicity of the polymer as compared to conventional polyurethane porous foams. This is because, after the liquid cosmetic is filled in the foam, the hydrophobic polymer does not diffuse the liquid component of the cosmetic and does not escape through the pores to the outside of the porous foam.
본 발명에 따른 다공성 폼에서 NBR 과 SBR의 중량비는 99:1 내지 70:30일 수 있다, 바람직하게는 99:1 내지 80:20일 수 있다. NBR과 SBR의 함량비에 있어서 SBR의 함량이 30중량%를 초과하고 NBR의 함량이 낮아지는 경우, 다공성 폼의 경도가 높아져서 딱딱해지는 반면 내구성은 낮아질 수 있고, 메이크업시 내용물이 퍼프에 침적이 잘 안될 수 있으며, 화장료 조성물 함침 후에 다공성 폼이 팽창되어 부풀어오르는 문제점이 발생할 수 있다. 반면에 SBR의 함량이 1 중량% 미만으로 NBR의 함량이 높아지는 경우에는, 다공성 폼의 경도가 낮아져서 너무 무르게 되며, 화장료 조성물 함침 후에 다공성 폼이 팽창되어 부풀어오르는 문제점이 발생할 수 있다.The weight ratio of NBR and SBR in the porous foam according to the present invention may be 99: 1 to 70:30, preferably 99: 1 to 80:20. When the content of NBR and SBR exceeds 30% by weight and the content of NBR is low in the content ratio of NBR and SBR, the hardness of the porous foam becomes high and the hardness may be low while the durability may be lowered. It may not, and may cause a problem that the porous foam is expanded and swelling after impregnating the cosmetic composition. On the other hand, when the SBR content is less than 1% by weight, the content of NBR is high, the hardness of the porous foam is low, too soft, and may cause a problem that the porous foam is expanded and swelling after impregnating the cosmetic composition.
상기 다공성 폼은 화장료 조성물을 함침하기 전 애스커(ASKER) 경도기 F형(Type F) 기준으로 30 내지 80의 경도를 가질 수 있다. 더 바람직하게는, 40 내지 70, 더욱 바람직하게는 45 내지 60의 경도를 가질 수 있다. 다공성 폼의 경도가 30 미만으로 너무 무른 경우 다공성 폼을 가압하였을 때 너무 무른 성질로 인하여 저점도의 액상 화장료의 경우 과도한 배출이 발생할 수 있을 뿐 아니라, 다공성 폼의 반발탄성력 또한 낮아지게 되어 사용감이 저하될 수 있다. 경도가 80을 초과하는 경우에는, 다공성 폼을 가압하여 화장료를 토출시키는데 요구되는 힘이 커지므로, 다공성 폼으로부터 화장료를 용이하게 토출시키기 어려운 문제점이 발생할 수 있다.The porous foam may have a hardness of 30 to 80 based on an ASKER hardness tester Type F before impregnating the cosmetic composition. More preferably, it may have a hardness of 40 to 70, more preferably 45 to 60. If the hardness of the porous foam is too soft, less than 30, when the porous foam is pressurized, too soft liquid may cause excessive discharge in the case of low-viscosity liquid cosmetics, and the resilience of the porous foam is also lowered. Can be. When the hardness exceeds 80, since the force required to pressurize the porous foam to eject the cosmetic becomes large, it may be difficult to easily eject the cosmetic from the porous foam.
본 발명에 따른 다공성 폼은 함침된 화장료가 바닥으로 가라앉지 않도록 하는 정도의 셀 크기를 가질 수 있으며, 셀 크기가 50 내지 2,000 ㎛일 수 있으며, 바람직하게는 50 내지 1000 ㎛, 더 바람직하게는 80 ㎛ 내지 1,000 ㎛, 더욱 바람직하게는 80 ㎛ 내지 500 ㎛의 셀 크기(cell size)를 가질 수 있다. "셀 크기"는 광학 현미경(NIKON ECLIPSE 80i)으로 측정한 수치일 수 있다. 셀의 크기는 화장료를 함침시키기 위하여 다공성 폼이 보유하고 있는 미세공간의 크기와 관련이 있다. 따라서, 셀의 크기가 50 ㎛ 미만으로 너무 작으면 다공성 폼 내로의 화장료의 함침 및 다공성 폼에서 화장료의 토출이 어려운 문제점이 발생할 수 있다. 반면에 셀의 크기가 2,000 ㎛를 초과하여 너무 크게 되면 다공성 폼 내로의 화장료의 함침은 용이하지만, 다공성 폼을 가압 시 과도한 양이 토출되거나 또는 함침된 화장료가 다공성 폼 하부에 가라앉는 문제점이 발생할 수 있다. The porous foam according to the present invention may have a cell size such that the impregnated cosmetic does not sink to the bottom, and the cell size may be 50 to 2,000 μm, preferably 50 to 1000 μm, more preferably 80 It can have a cell size (μm to 1,000 μm, more preferably 80 μm to 500 μm). "Cell size" can be a value measured with an optical microscope (NIKON ECLIPSE 80i). The size of the cell is related to the size of the microspace held by the porous foam to impregnate the cosmetic. Therefore, if the size of the cell is too small, less than 50 μm, problems of impregnation of the cosmetic into the porous foam and dispensing of the cosmetic from the porous foam may occur. On the other hand, if the size of the cell is too large, exceeding 2,000 μm, it is easy to impregnate the cosmetic into the porous foam. However, when pressurizing the porous foam, an excessive amount may be discharged or the impregnated cosmetic may sink into the lower portion of the porous foam. have.
본 발명에 따른 다공성 폼은 함침된 액이 가라앉지 않도록 하는 정도의 기공수를 갖도록 하는 것이 바람직하고, 예를 들면 인치당 셀 수가 20 내지 120 ppi일 수 있으며, 바람직하게는 50 내지 100 ppi일 수 있으며, 더 바람직하게는 인치당 셀 수가 70 내지 90 ppi일 수 있다. 인치당 셀 수의 측정은 화상분석기를 이용하여 100 배 확대한 이미지를 측정한 후에, 평균 셀 크기를 측정하고, 기준 길이(1 인치, 약 2.54cm)에 들어가는 셀의 수를 환산하여 측정할 수 있다. 1인치 당 포어 수가 30 ppi 미만인 폼은 포어 수가 적어 저점도 화장료 조성물의 유동성을 제어하기가 어렵고, 적정량의 저점도 화장료 조성물을 함침시키기 곤란할 수 있으며, 1인치당 포어 수가 120 ppi를 넘는 폼은 저점도 화장료 조성물을 효과적으로 담지할 수 없어 화장료 조성물을 침전 또는 분리시킬 수 있고, 조성물의 배출을 제어하기 어렵다.The porous foam according to the present invention is preferably to have a pore number to the extent that the impregnated liquid does not sink, for example, may be 20 to 120 ppi cells per inch, preferably 50 to 100 ppi More preferably, the number of cells per inch can be 70 to 90 ppi. The number of cells per inch can be measured by measuring an image 100 times magnified using an image analyzer, measuring the average cell size, and converting the number of cells that fall into a reference length (1 inch, about 2.54 cm). . Foams with less than 30 ppi of pores per inch have a low pore number, making it difficult to control the flowability of low viscosity cosmetic compositions, impregnating an appropriate amount of low viscosity cosmetic compositions, and foams with more than 120 ppi pores per inch. Since the cosmetic composition cannot be effectively supported, the cosmetic composition can be precipitated or separated, and it is difficult to control the discharge of the composition.
본 발명에 따른 다공성 폼은 오픈 셀(open cell) 구조를 가질 수 있다. 폼이 클로즈드 셀(closed cell) 구조를 가지는 경우 기포가 폼 내에 갇혀 화장료 조성물이 용이하게 함침되지 않을 수 있으므로 오픈 셀(open cell) 구조를 가지는 것이 바람직하다. 본 발명에서 "오픈 셀"은 그물망 구조를 말하고, "클로즈드 셀"은 기포상으로 풍선과 같은 폼을 가지는 것을 의미한다.The porous foam according to the present invention may have an open cell structure. When the foam has a closed cell structure, it is preferable to have an open cell structure because bubbles may be trapped in the foam and the cosmetic composition may not be easily impregnated. In the present invention, "open cell" refers to a network structure, "closed cell" means having a bubble-like foam in the form of bubbles.
바람직하게는, 상기 다공성 폼은 애스커(ASKER) 경도기 F형(Type F) 기준으로 30 내지 80의 경도를 가지며, 셀 크기가 50 내지 2,000 ㎛이고, 1인치당 셀 수가 30 내지 120 ppi일 수 있다.Preferably, the porous foam has a hardness of 30 to 80 based on the ASKER hardness tester Type F, the cell size is 50 to 2,000 ㎛, the number of cells per inch may be 30 to 120 ppi have.
본 발명에 따른 다공성 폼의 밀도는 0.02 내지 0.3g/cm3일 수 있다. 바람직하게는 0.05 내지 0.3 g/cm3 일 수 있으며, 더욱 바람직하게는 0.05 내지 0.1 g/cm3 일 수 있다. 이러한 밀도의 측정은, 지름 40 mm, 두께 9T로 하여 부피가 동일하다는 가정 하에 무게를 측정한 후에 밀도를 계산한다. 다공성 폼의 밀도는 화장료를 함침시킬 수 있는 내부 공간과 관련이 있을 뿐 아니라, 화장료의 토출을 위해 필요한 가압의 크기에도 영향을 미칠 수 있다. 구체적으로 다공성 폼의 밀도가 0.3 g/cm3 초과하여 높은 경우, 화장료를 함침할 수 있는 내부 공간이 부족하여 효과적인 함침이 어려울 수 있을 뿐 아니라 화장료의 토출을 위해 가해야 하는 압력 또한 높아지므로 사용에 바람직하지 않을 수 있다. 반면에 다공성 폼의 밀도가 0.02 g/cm3 미만으로 낮은 경우에는 다공성 폼을 가압 시 화장료의 토출량이 과도할 수 있다.The density of the porous foam according to the present invention may be 0.02 to 0.3 g / cm 3 . Preferably it may be 0.05 to 0.3 g / cm 3 , more preferably 0.05 to 0.1 g / cm 3 It can be. The density is calculated after the weight is measured under the assumption that the volume is the same with a diameter of 40 mm and a thickness of 9T. The density of the porous foam is not only related to the interior space that can impregnate the cosmetic, but can also affect the amount of pressurization required for the ejection of the cosmetic. Specifically, when the density of the porous foam is higher than 0.3 g / cm 3 , there is not enough internal space for impregnating the cosmetics, so that the effective impregnation may be difficult and the pressure to be applied for discharging the cosmetic is also increased. It may not be desirable. On the other hand, when the density of the porous foam is lower than 0.02 g / cm 3 may be excessive discharge amount of the cosmetic when pressing the porous foam.
본 발명에 따른 다공성 폼은 에스터 오일, 휘발성 실리콘 오일, 물, 극성 유기 자외선 차단제에 대한 내화학성을 가질 수 있다. 다공성 폼은 함침되는 화장료와의 관계에서 높은 안정성을 가짐으로써 화장료의 변질을 방지해야 함은 물론이고, 다공성 폼의 변질 또는 변형을 일으키지 않아야 한다. The porous foam according to the invention may have chemical resistance to ester oils, volatile silicone oils, water, polar organic sunscreens. The porous foam should have high stability in relation to the cosmetic to be impregnated to prevent deterioration of the cosmetic and, of course, should not cause deterioration or deformation of the porous foam.
본 발명에 따른 다공성 폼은 피막 가공 또는 플록(flock) 가공한 폼을 포함할 수 있다. 본 발명에 있어서, "피막 가공 폼"은 고무, 폴리비닐 또는 폴리우레탄과 같은 중합체 폼에 막을 입힌 것으로, 피막 가공 전 폼에 비해 일반적으로 셀의 크기가 작다. 본 발명에 있어서, "플록 가공 폼"은 고분자 폼에 섬유를 붙인 것이다. 상기 섬유는 면, 아크릴, 폴리아미드, 나일론, 폴리에스테르, 실크 및 레이온으로 이루어진 군으로부터 선택된 하나 이상일 수 있으며, 구체적으로 면, 아크릴, 폴리아미드, 나일론, 폴리에스테르, 실크, 면과 아크릴, 면과 레이온, 나일론과 폴리에스테르 및 면, 아크릴과 폴리에스테르를 포함한다.The porous foam according to the present invention may include a foamed or flocked foam. In the present invention, a "foamed foam" is a coating of a polymer foam such as rubber, polyvinyl or polyurethane, and generally has a smaller cell size than the pre-foamed foam. In the present invention, "flocked foam" is a fiber adhered to a polymer foam. The fiber may be one or more selected from the group consisting of cotton, acrylic, polyamide, nylon, polyester, silk, and rayon, specifically cotton, acrylic, polyamide, nylon, polyester, silk, cotton and acrylic, cotton and Rayon, nylon and polyester and cotton, acrylic and polyester.
본 발명에 따른 다공성 폼은 에어리스, 튜브, 스틱, 스템프 용기 구조에 적용될 수 있으며, 일정한 압력 혹은 전단에 의해서 스퀴즈가 용이하고 배출이 잘 되는 물성을 가진다.Porous foam according to the present invention can be applied to the airless, tube, stick, stamp container structure, it is easy to squeeze by a constant pressure or shear, and has good physical properties.

Such cosmetics may be, but are not limited to, makeup primers, makeup bases, foundations, powders, twin cakes, eye shadows, teak powders, blushes, concealers, facts, sunscreens, liquid formulations or airless formulations.
본 발명에 따르면, 사용되는 화장료 조성물의 점도는 2,000 cps 내지 20,000 cps 일 수 있다. 점도가 20,000 cps를 초과하면 다공성 폼 내에 화장료의 함침 및 토출이 어려울 뿐 아니라 화장품을 피부에 도포시 끈적이고 무거운 사용감을 줄 수 있으며, 점도가 2,000 cps 미만으로서 낮은 경우에는 낮은 점도로 인하여 다공성 폼 내에서 균일하게 유지하기 어려우므로 다공성 폼의 하부에 가라앉을 수 있다.According to the invention, the viscosity of the cosmetic composition used may be 2,000 cps to 20,000 cps. If the viscosity exceeds 20,000 cps, the impregnation and dispensing of the cosmetics in the porous foam is not only difficult, but also gives a sticky and heavy feeling when applying the cosmetics to the skin.If the viscosity is lower than 2,000 cps, the viscosity is low in the porous foam. It is difficult to maintain uniformity at and may sink to the bottom of the porous foam.
본 발명에 따른 화장료 조성물은 오일을 외부상으로 하여 물이 내부상으로 분산되어 있는 유중수형(water in oil)의 화장료 조성물일 수 있다. 오일과 물의 비율 조절로 점도 등의 물성 조절이 가능하고, 다공성 폼에의 함침 정도, 가압 시의 토출 정도 조절이 가능하다. 그러나, 본 발명에서 정의된 점도의 정도를 갖는다면, 유중수형 화장료 뿐만 아니라, 수중유형, 가용화형, 오일타입형 등의 화장료도 사용이 가능하다.
