종래 저점도 화장료 조성물, 특히, 액상의 화장료 조성물은 주로 진공 용기, 펌프 용기 또는 유리 용기 등에 충진되어 유통 및 보관되었다. 하지만 이들 용기들은 휴대가 불편하다는 단점이 있다. 따라서, 외출시에도 간편하게 화장을 하거나 수정할 필요성이 증가함에 따라, 휴대가 편리한 화장용구에 대한 요구가 있었다.
최근, 담지체에 저점도의 화장료 조성물을 담지시켜 휴대가 간편하게 만든 화장용구가 개발되었다. 이러한 화장용구에서 저점도의 화장료 조성물은 다공성 담지체의 포어 내에 위치하게 된다.

도 5는 본 발명의 제3실시예에 따른 담지체의 사시도이다.
접착층(30)에는 부분적으로 빈 부분이 형성되어 있으며, 이에 의해 제1접착면(11)과 제2접착면(21)은 부분적으로 접착되어 있다.
제2실시예 및 제3실시예에 따르면 제1담지체(10)와 제2담지체(20)는 서로 접착되어 있으면서도, 접착층(30)없이 직접 맞닿는 부분을 가지게 된다. 이에 의해 화장료(40)가 제1담지체(10)와 제2담지체(20) 사이에서 원활하게 이동할 수 있다.
이하에서는 본 발명에 따른 담지체의 제조방법을 설명한다.
도 6은 본 발명에 따른 담지체 제조방법의 일실시예를 나타낸 것이다.
제1담지체(10), 제2담지체(20) 및 접착시트(31)를 준비한다. 접착시트(31)는 폴리올레핀계 또는 폴리에스테르계 재질이며, 얇은 시트 형상을 가지고 있다. 접착시트(31)는 저온에서 용융되는 저분자의 섬유질을 그물형태방사한 부직포(nonwoven) 형태의 핫멜트 접착제일 수 있으며, 웹형태를 가지고 있을 수 있다. 접착시트(31)는 비교적 낮은 온도에서 접착성능을 나타낼 수 있으며, 예를 들어, 연화점(DSC softening point)이 105℃ 이하, 110℃ 이하 또는 120℃ 이하일 수 있으며, 더 구체적으로는 80℃ 내지 105℃, 80℃ 내지 110℃ 또는 80℃ 내지 120℃일 수 있다.
제1담지체(10)와 제2담지체(20) 사이에 접착시트(31)를 위치시키고, 접착시트(31)를 용융한다. 용융은 열풍을 이용하여 수행할 수 있으며, 접착시트(31)가 용융되면서 접착이 이루어진다. 접착시트(31)는 용융되어 접착층(30)을 형성하고 제1담지체(10)와 제2담지체(20)를 접착시킨다.
제1담지체(10)와 제2담지체(20)를 접착한 이후 화장료를 담지시킨다.
접착을 확실히 하기 위해 용융 중 또는 용융 후에 프레스 과정을 거칠 수 있다.
접착시트(31)를 이용한 접착은 전기퓨징프레스(electric fusing press), 가열된 롤, 열풍, 방사열 또는 스팀 프레스 등을 이용하여 수행될 수 있다. 열접착온도는 105℃ 내지 125℃일 수 있다.
도 7은 본 발명에 따른 담지체 제조방법의 다른 실시예를 나타낸 것이다.
제2담지체(20) 상에 접착시트(31)를 위치시키고 용융시켜 접착층(30)을 형성한다. 접착층(30)이 굳기 전에 제1담지체(10)를 접착층(30) 상에 위치시키고 제1담지체(10)와 제2담지체(20)를 접착시킨다.
이상 설명한 제조방법은 다양하게 변화할 수 있다. 접착시트(31)의 형태 및 분포는 다양하게 변화할 수 있으며, 이에 의해 접착층(30)의 형태도 달라진다. 또한, 접착시트(31)를 사용하지 않고 구상의 접착제나 액상의 접착제 등 다양한 다양한 형태의 접착제를 사용하여 접착층(30)을 형성할 수 있다.
이하 실험예를 통해 본 발명을 더욱 상세히 설명한다.
제1담지체(10)로 두께 1mm의 폴리우레탄 폼을 사용하였다. 폴리우레탄 폼은 폴리에테르와 폴리에스테르가 5:5이며, 폴리카보네이트디올을 함유하여 내화학성이 강화된 습식우레탄 폼이다.
제2담지체(20)로는 두께 8mm의 폴리에테르계 폴리우레탄 폼을 사용하였다
실시예에서 접착층(30)은 폴리에스테르계 저온 반응성 접착시트(31)를 이용하여 형성하였다. 비교예로는 이소시아네이트계 접착제를 사용하였다.
접착층(30)은 제1접착면(11)과 제2접착면(21) 전체에 걸쳐 형성되었으며, 열풍을 이용하여 접착시트(31)를 용융하였다. 용융 후 프레스, 세척 및 건조 과정을 거쳤다.
담지체 제조 후 알코올에 대한 분리강도를 테스트하였다. 사용된 알코올 용액은 에탄올 100%, 에탄올 15%, 에탄올 10% 및 에탄올 5%의 총 4가지였다.
테스트에서는 1)　담지체를 50℃ 항온조에서 알코올 용액 내에 7일 방치한 후 2) 핀셋으로 분리여부 확인하였으며 3)　핀셋으로 분리되지 않은 경우에는　세척후 내용물이 90%이상 제거된 상태에서 분리강도 측정(푸쉬풀게이지로 측정, 상단면은 집게가위 또는 푸쉬풀 집게로 고정하여 당기고 하단면은 지그 또는 손으로 고정)하였으며 4)　푸쉬풀게이지로 0.4kg.f로 당겼을때 분리여부 확인하였다(푸쉬풀게이지의 속도는 10mm/sec).
실험결과는 다음 표 1과 같다.
EtOH 100% EtOH 15% EtOH 10% EtOH 5%
비교예 0 Kg.f 0.1 kg.f 0.1 kg.f 0.2 kg.f
실시예 0.4 Kg.f 0.4Kg.f 0.6Kg.f 0.8Kg.f
실험결과를 보면 비교예에서는 에탄올 100%에서는 핀셋으로 분리되었으며, 에탄올 함량이 낮은 경우 핀셋으로 분리되지는 않았지만 낮은 분리강도를 나타낸다.
반면, 실시예에서는 에탄올 100% 용액에서도 큰 분리강도를 보여주고 있어 담지체가 안정적으로 접착되어 있음을 보여주고 있다.
전술한 실시예들은 본 발명을 설명하기 위한 예시로서, 본 발명이 이에 한정되는 것은 아니다. 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 이로부터 다양하게 변형하여 본 발명을 실시하는 것이 가능할 것이므로, 본 발명의 기술적 보호범위는 첨부된 특허청구범위에 의해 정해져야 할 것이다.
