This study compared the physicochemical properties of root hair of white ginseng (WG), root hair of tissue cultured mountain ginseng (MG), root hair of red ginseng (RG) and extruded ginseng samples. The comparison of crude ash and total sugar resulted insignificant differences between extruded and raw samples. MG had a higher content of crude ash, crude protein, amino acids and polyphenolic compound than WG and RG; the total sugar and reducing sugar were highest in RG. Crude fat and acidic polysaccharide in RG and WG were similar to and higher than MG. Crude saponin of treated samples WG1 (moisture content 25%, barrel temperature $110^{\circ}C$) and WG3 (moisture content 35%, barrel temperature $110^{\circ}C$) were 9.80% and 9.73%, respectively, which were the highest among ginseng samples. In conclusion, the extrusion process can be applied to red ginseng manufacturing, and some characteristics of MG were higher than in RG and WG.

As part of research to develop a permanent wave-reducing agent for hair, in the current study, 0.1%-1.0% of Polyquaternium-10 was added to a permanent reagent containing Nicotinoyl Dipeptide-23 to prepare the agent, which was tested on damaged hair. The pH change was relatively stable even after a date, but due to the hair's natural composition, 0.1%-0.6% of the Polyquaternium-10 concentration according to pH was suitable. The temperature safety experiment demonstrated it to be stable at a high temperature and at room temperature, but when a Polyquaternium-10 concentration of 0.9% or higher was added at 0℃, coagulation occurred. In terms of the force efficiency of permanent wave formation, wave efficiency lowered as the concentration increased: the longer the wave lasts, the lower the Polyquaternium-10 concentration. The permanent moisture content was found to be higher as the concentration of Polyquaternium-10 increased. Therefore, when Polyquaternium-10 is applied to the permanent wave-reducing agent, considering stability, permanent formation, durability, and moisture rate, the most suitable concentration was found to be that of Polyquaternium-10 in the cysteine-reducing agent. A novel finding from this study is that as the concentration of Polyquaternium-10 increases, the consistency of the permanent wave-reducing agent changes, shifting from a liquid to a viscous liquid formulation.

세정 과정에서 물에 의한 단백질 소실을 차폐막을 통해서 방지 하고자 먼저 모발 내부의 물 거동 경로를 파악하였다. 이를 위해서 소수성을 가지는 건강한 모발과, 모발 내부는 정상이지만 표면의 최외곽 지질층에서 18-methyleicosanoic acid (18-MEA)만 소실시켜 친수성이 된 모발과, 다시 표면에 18-MEA를 결합시킨 회복모를 이용해서 모발 수분의 거동을 파악하였다. 모발에 열을 가할 때 일어나는 수분 증발에 따른 질량 변화를 관찰한 결과 표면이 소수성인 모발들은 39 s와 151 s의 두개의 시간 상수로 감소하였다. 이에 반해 표면이 친수성으로 변한 손상 모발에서는 83 s의 하나의 빠른 시간 상수로 감소함을 확인하였는데, 이는 모발 내부에 있는 비결합과 결합 수분들이 외곽으로 빠져나올때 모발 표면에 소수성 막이 없음으로써 바로 용출됨을 반증한다. 따라서 세정과정에서 모발 내부의 단백질 용출을 효율적으로 방지하기 위해서는 모발 표면을 소수성 코팅하여 물분자의 거동을 저지시킬 필요가 있을 것이라는 가정한 결과 친수성 polyethylene glycol (PEG)를 코팅한 경우 179 ㎍/mL의 단백질이 용출한데 반해서 소수성 polydimethylsiloxane (PDMS)를 코팅한 모발은 보다 적은 148 ㎍/mL를 용출하였으며, 표면을 소수성 및 친수성으로 코팅하여 모발 내부 단백질을 검량하여 비교하였다. 마침내 소수성 차폐막이 세정 과정에서 모발 단백질 소실을 방어하는 방법이 됨을 확인하였고, 이 소수성 지표를 lateral force microscopy (LFM) 값으로 환산하여 정리하였다. 마침내 이 연구 결과물은 세정 과정에서 발생하는 단백질 소실을 소수성 코팅막을 부여함으로써 막을 수 있는 모발 세정제품 개발에 기여할 수 있다.

The purpose of this study is to provide beauticians with the fundamental material for them to use effectively heat permanent wave and satisfy their customers. It carried out an experiment with hair of a woman in her late twenties to investigate the change of physical and morphologic characteristics by its water content when performing heat permanent wave. It evaluated the water content as 0g, 1g, 2g, 3g and 4g respectively when performing the heat permanent wave on hair, then it compared and observed the wave type, tensile strength and elongation for its physical change also observed the morphologic change by scanning electronic microscope and transmission electronic microscope. The result of experiment on the physical specificity revealed that the wave was the most ideal when the water content was 2 g. The material with much water content made wave but the result was not satisfied. In the case of hair with water content of nearly 0g didn't make wave. In terms of tensile strength and elongation, the tensile strength was generally reduced as hair was damaged, on the contrary, the elongation was increased. It observed the change of morphologic characteristic and got the result that the damage on hair cuticle was deepen as its water content was decreased. It also showed the result that damage happened on hair cuticle more than hair cortex with the observation of fine structure on hair section by transmission electronic microscope. Generally chemical treatment damaged hair. Under consideration of this aspect, the ultimate goal of this thesis is to minimize the damage of hair caused by chemical treatment and get the satisfaction on the hair style. The result of experiment presented that the hair showed the best result when its water content was 2 g.

본 연구는 마스크팩 유효성분을 흡착시킨 엔드 페이퍼를 퍼머넌트 웨이브 시술시 모발에 미치는 영향을 알아보고자 수행하였다. 시중에 판매되는 마스크팩 중 청귤, 콜라겐, 어성초 유효성분을 함유한 마스크팩을 구입하여 엔드 페이퍼에 흡착시켜 퍼머넌트 웨이브를 시술하였다. 실험 방법으로 모발 굵기, 모발 보습력, 인장강도, SEM을 이용한 모표피 관찰, EDS를 이용한 모발 구성 원소 분석을 하였다. 실험 결과 어성초 유효성분을 엔드 페이퍼에 처리한 실험군이 모발 굵기, 인장강도, 모표피 관찰, 모발 구성 원소 분석 결과 모발 보호효과가 있는 것으로 확인되었다. 또한 청귤 유효성분을 엔드 페이퍼에 처리한 실험군은 모발 보습력 실험 결과에서 비교적 많은 수분을 함유하고 있는 것으로 확인되었다. 유효성분들이 함유된 기초화장품 제품들을 활용하여 모발화장품으로 개발하여 활용하고, 산업현장에서 화학시술 시에 적용할 수 있도록 다양한 재료와 도구들에 대한 개발과 연구가 진행되기를 바라는 바이다.

본 연구는 색상을 함유하고 있지 않은 자연계열의 염모제인 9/00과 14/00을 여성의 건강모발에 염색한 후 염색된 모발을 열분석과 주사전자현미경을 이용하여 모발의 물리 화학적인 변화를 규명하였다. 열분석에서 정상 모발시료의 경우 열에 대한 연소 반응이 비교적 빠르게 나타났으며, 9/00 염색모발의 경우에는 건강모발과 14/00염색 모발의 중간 정도의 연소반응을 나타냈고, 14/00 염색 모발의 경우에는 열에 대한 연소반응이 비교적 느리게 나타나는 것을 확인하였다. 이는 고명도의 염모제일수록 모발의 수분 함유량이 감소되었다는 것을 의미하며, 모발 내부로 침투한 산화물과 염료 분자로 인하여 모발의 화학적 변화가 야기된 것으로 사료된다.

Omega-3 fatty acids are a specific type of unsaturated fat that the body cannot manufacture on its own, so they must be obtained from food which is essential fatty acids (EFAs). Omega-3 fatty acids consist of three types which are a-Linolenic Acid (ALA), Eicosapentaenoic (ELA), and Docosahexaenoic Acid (DHA). Especially, EFAs help to prevent skin and hair drying, acne, eczema, prevention from allergies, brittle nails, rashes, and tiny lumps. The aim of this study is to investigate improvement and protection for hair damaged by chemical treatment with omega-3 formulated shampoo. We selected virgin hair sample and divided into two groups for bleaching once and three times and then damaged hair by changing the number of hair bleaching (twice with interval of 15 minutes). Each bleached hair was treated by five different kinds of shampoo (Control, Horse shampoo, DHA shampoo, EPA shampoo, Omega-3 shampoo mixture). Apart from this, EPA/DHA 2, 5, 8, 10 and 12% shampoo were prepared and treated to hair for comparing rate of progress in damaged hair. To quantify improved condition of damaged hair, we performed Scanning Electron Microscope (SEM) for ultrastructure of damaged hair fraction, measurement of thickness change and BCA Protein Assay for recovery rate of damaged hair. The moisture in hair was measured by Thermal analysis machine. In results, we observed the particle of hair surface damaged by bleaching treatment were well improved with treatment with EPA and DHA shampoo. Also, quantity of protein was lowered with higher concentration of EPA & DHA i.e., 8 and 12 % then compared with horse oil shampoo in three times treatment group. It shows that bleached hair have been recovered by treating rapidly and get protective coat. In conclusion, EPA and DHA shampoo improved damaged hair, especially with EPA / DHA 12% shampoo. Also, EPA shampoo could protect the damaged hair depending on increasing concentration of EPA. Therefore, we conclude omega-3 shampoo could make damaged hair protect and get healthy hair environment.

A new quaternary ammonium compound, hydrolyzed ginseng-sapoin quaternary (HGSQ), from hydrolyzed Korean ginseng-saponin and 2, 3-epoxypropyltrimethyl ammonium chloride has been developed as a conditioning agent for hair care products. This structure has the hydrophilic group from the introduced cationic and the hydrophobic group from the aglycone of ginseng saponin. Its properties: surface tension, conductivity, critical micelle concentration, eye irritation, sorption onto hair, force reduction (%) for 20% extension and moisture retention effect comparing with the commercial standards. Also half-head tests of HGSQ-containing shampoo were carried out to compare the conditioning effects in shampoos.
