        Nail products such as polish, polish remover and acrylates are widely used. And nail products have problems and risks of not only nail damage but also neurological abnormality, irritation of skin and mucous, reproductive disorder. So that, the aim of this study is to observe change of physical property and morphology on nail by treatment with nail removers. 5 women`s nails were collected and divided into 3 groups (non-treated, acetone remover treated, acetone free remover treated) and treated with two polish removers in one time, 3-times and 5-times. The thickness of transverse and roughness of surface were measured and observed after polish and polish remover treatment by hair diagnostic apparatus, SEM and AFM. The findings showed that the nails in the acetone-content polish remover group were significantly thin from 5.2±0.1 μm to 4.7±0.3 μm after 3-times of treatment and to 4.3±0.2 μm after 5-times of treatment (p<0.05), while those treated with acetone-free removers became also significantly thin from 5.1±0.1 μm to 4.9±0.1 μm after 3-times and to 4.6±0.1 μm after 5-times of treatment (p<0.05) in compared to non treated group. Observation with SEM from the morphological viewpoint, transverse and surface of the nails in the non-treated group featured relatively solid and high adhesion in the intermediate layer of keratine. After 3- and 5-times of treatment in repeatedly treated group. The aceton plish remover group with some scratches were found to be lysated and clotted and cuticles came off heavily from the transverse. In case of acetone-free remover group, however, a slight crack, clotting and crumbs appeared between layers after 3- and 5-time treatment and peeling off process of cuticles were slower compared to the case of acetone-content polish remover group by observation of SEM. The nails in acetone-content polish remover group was significantly increased in the roughness from 0.56±0.06 μm to 0.66±0.03 μm after 3-times treatment and to 0.78±0.02 μm after 5-times treatment (p<0.05), while the surface treated with acetone-free remover treated group was observed to have slightly increase of roughness from 0.56±0.06 μm to 0.58±0.11 μm after 3 times of treatment and to 0.61±0.02 μm after 5 times by AFM (p<0.05). These data suggested that acetone-free remover may be damaged to nails weaker than acetone-content remover.

        젤 폴리쉬 제거방법에 따른 손톱 손상도 비교

        장유진 ( Jang Yu Jin ),유태순 ( Yoo Tai-soon ) 한국디자인트렌드학회 2015 한국디자인포럼 Vol.48 No.-

        본 연구는 젤 폴리쉬 제거 시 손톱의 형태학적 특성을 비교, 분석하여 젤 폴리쉬 제거 시 손톱 손상도를 과학적으로 분석하여 손톱 손상을 최소화 하는 방법을 제안하는 것에 목적이 있다. 이를 위해 본 연구에서는 대구지역의 2·30대 여성 5명을 대상으로 실험을 실시하였고, 원자력현미경을 이용하여 손톱 표면을 관찰하였으며 통계처리는 IBM SPSS Statistics 22 for Window 프로그램을 이용하였다. 연구 결과, 젤 폴리쉬를 시술 하지 않은 무처치 손톱의 경우 2차원이미지와 3차원이미지 측정 결과 색의 농도 차이가 거의 없고 균일하여 손톱 표면의 높낮이가 거의 없는 것으로 나타났다. 젤 폴리쉬를 제거하기 위해 속 오프 하였을 때 실험대상자들의 손톱이 무처치 손톱과 비교하여 반복처치 시 손톱 표면의 거칠기가 증가한 것을 확인 할 수 있었다. 또한 그라인드 오프를 하였을 때에도 속 오프와 마찬가지로 실험대상자들의 손톱이 무처치 손톱과 비교하여 반복 처치 시 손톱 표면의 거칠기가 증가한 것을 확인할 수 있었다. 손톱 표면의 거칠기 수치에 대해 속 오프와 그라인드 오프를 비교 하였을 때 그라인드 오프의 수치가 속 오프에 비해 낮게 나타났다. 이는 그라인드 오프가 속 오프에 비해 손톱 손상도가 적게 나타나는 것을 의미한다. 또한 손톱 표면의 높이 차이 수치에 대해 속 오프와 그라인드 오프를 비교 하였을 때 속 오프에 비해 그라인드 오프가 손톱 표면의 높이 차이가 낮게 나타났다. 이는 그라인드 오프가 속 오프에 비해 손톱 손상도가 적은 것을 의미한다. The purpose of this study is to compate and analyze the morphological characteristics of fingernails when gel polish is removed; to scientifically analyze nail damage when gel polish is removed from nails; and to suggest a way to minimize nail damage. For this, an experiment of 5 females in their twenties and thirties was conducted, and their nail surfaces were observed using an atomic force microscope. The IBM SPSS Statistics 22 for Window program was used for the statistical processing. The findings of the study are as follows: As for the untreated nails where gel polish was not applied, the results of measuring two-dimensional images and three-dimensional images showed that there were few differences in color density and the density was uniform and that the surfaces of their nails were almost even. When soaked off to remove gel polish, the participants` nails got rougher by repeated treatments compated with those of untreated nails. In addition, it was also confirmed that the degree of roughness of their nails increased by repeated treatments when ground off just like that of nails being soaked. When the roughness degree of soak-off was compared with that of grind-off, the defree of grind-off appeared to be lower than that of soak-off. This means that grind-off damages nails less than soak-off. And regarding the unevenness of nails, the nails ground off were found to be more even than the nails soaked off, which means that grind-off damages nails less than soak-off.
