천연염모제를 개발하기 위하여 밤외피와 오배자 용액을 UV흡수대, chitosan과 gelatin에 대한 반응 및 중금속과 항균성을 조사하여 그 특성을 파악하였다. 그 결과, 전량 폐기되는 밤외피를 자원으로 활용할 수 있는 경제성과 유해중금속이 검출되지 않아 인체에 안전하고 천연방부효과를 가져 저장성이 있어 상품가치가 있을 것으로 판단된다. 염료와 매염제에 함유된 tannic acid가 모발에 미치는 영향을 모발의 표면색상값과 샴푸, 자외선, 땀에 대한 견뢰도를 측정하여 평가하였다. 가장 높은 염착성을 갖는 매염제 종류로는 TFC-2였고 선매염과 동시매염 방법이 후매염 염색방법에 비해 높은 염착성을 보였다. 매염제의 처리농도와 온도가 높을수록 높은 염착력을 보이나 모발염색 시 실제 적용을 고려하면 TFC용액의 적정처리농도는 9%에서 12%이고, TA염료는 10%였다. 그리고 최적처리온도는 30∼40℃이며 pH는 3.5∼5.1일 것으로 판단된다.

Protease의 적정농도는 0.01 ～ 0.03%이고 0.1%농도로 처리할 경우 처리시간을 단축시킬 수 있었다. 또한 동시효소처리법이 전체 아미노산의 함량 변화가 적게 나타났다. Protease함유 TA염료는 유해중금속이 검출되지 않았고 피부 알러지 검사에서도 안전성이 확인되었다. 이상의 결과로 전통적으로 천연염색에 사용하였던 금속매염제를 최소화할 수 있는 소재로 protease와 Tannic Acid-FeCl3-Complex의 사용은 염색성 및 화학적 변화 개선에 도움을 줄 수 있는 새로운 매염제로서 탄닌염료와 함께 천연염모제로 유용하게 활용할 가치가 있다고 판단된다.

The characteristics, which have influence upon hair, were studied by applying protease and tannic acid to hair dyeing, as the alternative materials in metal mordant, which had been used as medium of traditionally helping natural dying, or as a plan for being able to minimize metal mordant. The purpose of this study was to confirm the applicability in natural hair dyes by grasping characteristics of dyestuff with the content of tannic acid prior to hair dyeing. Castanea sativa bark and Quercus oak gall contain tannic acid, thereby being known traditionally as tannic acid based dyestuff. As a result of surveying the absorber in dyestuff, Castanea sativa bark extracted of the maximum absorption spectrum (λmax) was indicated in 240 nm as for distilled water. In case of Quercus oak gall, the maximum absorption spectrum was shown in 220 and 300 nm, respectively, for distilled water and methanol. As a result of surveying the adsorption capacity in coloring matter by allowing Castanea sativa bark and Quercus oak gall to respond, respectively, to chitosan and gelatin, in case of Castanea sativa bark, the coloring matter was absorbed uniformly into a reactant, thereby having indicated dark brown and light brown. Quercus oak gall is generated the irregular blown sediment, thereby being inappropriate for being applied to hair dyeing. By studying metal components in Castanea sativa bark and Quercus oak gall, the appropriateness was examined as natural hair dyeing agent. As a result of comparing the metal components in the extraction of Castanea sativa bark and Quercus oak gall with oxidative hair dye and henna hair dye, Castanea sativa bark was under permission amount in harmful metal components. Quercus oak gall, aluminum (Al) was 35.446 ppm that is about two times higher than the permission amount in 16 ppm. Barium (V) was about 10% higher than the permission amount in 2 ppm. Henna colorant, Al and V showed the value that is about 50 times and about 30,000 times, respectively, higher than the permission amount. In this result, a case of henna, which is used as the representative vegetable hair dyestuff is judged to be likely to be the compound henna that contained a great quantity of metal components, not the purely vegetable extract. The accumulation in metal components due to repetitive use was expected. There was doubt about probability for side effect in scalp and hair. In the study of antimicrobial activity, Castanea sativa bark and Quercus oak gall showed antimicrobial activity in Gram positive bacillus and yeast, thereby being able to be expected the natural antiseptic effect. In the above result, Castanea sativa bark, as the dyestuff of containing tannic acid will safe during storage and has economic efficiency of reproduct, which are totally scrapped, thereby being judged to have value of commercialization as natural dyestuff. Given using the dyestuff in Castanea sativa bark (TA dyestuff) of containing tannic acid for hair dyeing, the metal mordant is required for enhancing dyeability and improving fastness. Using metal mordant leads to being expected demerit, which hair comes to be rough or the definition in color comes to lower, and being expected side effect on the skin. This study used Tannic Acid-FeCl3-Complex (TFC) as material, which can substitute for FeCl3 mordant. Given examining the results of hair dyeability, in case of TFC solution, the value of color in hair with independently mordant treatment in FeCl3 is similar, thereby having been valid as alternative mordant that can reduce the use volume in FeCl3. As for a method of dyeing TFC solution and TA dyestuff, the pre-mordanting and simultaneous-mordanting method was relatively higher in dyeability compared to the post-mordanting dyeing method. And, the proper concentration in TFC solution was from 9% to 12%, and TA dyestuff was 10%. The higher temperature led to an increase in dyeability. However, given considering the actual application to hair dyeing, the proper temperature is 30∼40℃, and pH 3.5∼5.1. In the result of measuring fastness, FeCl3 solution had low fastness to shampoo and sweat. CTA solution had low fastness to ultraviolet rays. TFC solution was enhanced fastness due to interaction between FeCl3 and CTA. In the above result, as a plan for being able to reduce the use of metal mordant, Tannic Acid-FeCl3-Complex (TFC) may be presented as mordant. However, the coloring matter in TA dyestuff had restriction that is absorbed only in the hair surface and that cannot be infiltrated into cortex, by having media as Fe ion and tannic acid. In order to reduce the use volume of FeCl3, which was contained in Tannic Acid-FeCl3-Complex (TFC) to improve dyeability. Thus, enzyme was treated together as medium that can help pigmentation inside the hair. In the experiment on hair dyeability of using enzyme, the luminosity value (L*) and color properties (a*, b*) in hair, which was treated with protease (Rhizopus sp.), reduced much, thus there was a remarkable effect on improving dyeability compared to the hair, which was treated with TFC solution. What the value of b*, which shows Yellowness, dropped notably is judged to be what the action of enzyme destroyed pheomelanin, thereby having enhanced dyeability. In the observation of SEM in the hair, which was treated with protease, the scale of the surface in the hair was destroyed much depending on concentration. The proper concentration in protease, which will enhance dyeability, was 0.01∼0.03%. When treating protease in high concentration (0.1%), the dyeing time was shortened by within 30 minutes. Thus, the swelling only in hydrophobic group of cuticle scale is judged to be probably effective. The responses in tannic acid and protease occurred simultaneously. Protease was absorbed in cuticle scale. Thus, tensile strength and flexibility in hair was thought to be enhanced. In order to examine the effect of protease treatment on a chemical change
