A Study on the Hair Dyeing Properties by Using Extracts of Grape Skin
Jong-Chul Seo, Chul-Ho Park
ABSTRACT
The purpose of this study is to examine the possibility of anthocyanin pigments of Grape skin. In order to achieve this purpose, anthocyanin concentration was analyzed by measuring absorbency from anthocyanin 540 nm of Grape skin and color changes were observed according to changes in temperature and pH through color measurement. hair dyeing of anthocyanin pigments was found to very good at 40℃ for 20 min. Unmordanted Hair dyeing was increased in dye intake (K/S) with increased dyeing temperature and hair color was changed from dark red to bright red. anthocyanin pigments were specially sensitive to pH and dye intake was decreased with increased pH. Higher acidity generally led to a stronger reddish tint, while higher alkalinity led to a decrease in red coloration and a stronger yellow tint. For hair dyeing, mordanting methods(pre-mordanting, simultaneous mordanting, or post-mordanting) should be selected in consideration of the characteristics of mordants (dye intake, lightless, chroma and color). Based only dye intake(K/S), while simultaneous mordanting was effective for FeSO4, MnSO4, AlK(SO4)2, CaCO3, Na2CO3, pre-mordanting was effective for MgSO4, CH3COOH, post-mordanting was effective for CuSO4, Co(NO3)2. The rate of colorfastness was decreased with repeating shampoo washing. From these results, we can confirm that the extracts from Grape skin may be useful in the materials of hair coloring dye.
