양파(Allium cepa) 외피 추출물이 모발의 미세구조에 미치는 효과

The Effects of Ultrastructure with Onion (Allium cepa) Skin Extracts on Human Hair Dyeing

본 연구의 목적은 양파 외피를 분상의 상태로 제조하여 모발염색의 최적에 조건을 규명하기 위해 V.H.에 4회 탈색 (B.H.)하여 시험모를 제작한 후 양파 외피 추출물을 시간, 온도, 농도, pH, 매염제 처리별로 조건을 달리하여 모발의 염색성과 기계적 형태학적 변화를 관찰하였다. 모발 표면을 주사전자현미경을 통해 관찰한 결과 모표피층이 완전 용해된 B.H.에 비해 양파 외피 추출물로 염색한 모발에 경우 약간 들떠있는 상태는 보이지만 모표피층이 형성되어 있는 것을 관찰할 수 있었다. 이와 같은 연구의 결과로부터 양파 외피에서 추출한 천연 색소는 분상의 염모제로 제조 시 대량 생산과 보관에 있어 효과적으로 실용화가 충분히 가능하다고 사료된다.

Onions are commonly available and easily processed, and since their skins are thrown away they could be very useful materials from the viewpoint of environmental preservation. This study aimed to process onion skins into the state of powder and look into the optimum condition for hair dyeing by decoloring virgin hair four times and observing the hair dyeing quality and its mechanical and morphologic changes by the different condition of onion skins in duration, temperature, density, pH, and mordant treatment. The observations of hair surface through scanning microscopy showed the formation of cuticle layer, though in a little blown-up state in the case of the hair dyed with onion skin application, when compared with bleaching hair with the completely dissolved cuticle layer. According to the above findings of experiments, the dyeing quality of the hair dyes with onion skin application was excellent, the dyeing was also feasible without mordants, and the use of Fe as the mordant increased dyeing exhaustion more, which would make it an effective hair dye. These results of the experiments indicate that the natural pigment extracted from onion skins can be actually used for hair dyeing from the viewpoints of the dyeing quality and the skin treatment.
