金昌奎 , 梁三柱 , 李玉燮 DOI: AbstractTensile strength and elongation of the ginseng saponin-treated hair were compared with those of collagen hydrolysate-treated hair. The absorbed of ginseng saponin into hair was measured by high speed liquid chromatography and identified by using the liquid scintillation counter. Sorption of collagen hydrolysate to hair was rapid in the first 30 min, but the rate nearly remained constant after one hour. On the contrary, the sorption of ginseng was increased with increased immersion time. The results indicate that saponin has better effect on hair than collagen hydrolysate. Also, the mechanism of absorption and increase of the tensile strength were suggested from the analysis of the strain-stress curve and surface activities. Key Words |

The interaction between surfactants and keratinous tissuesM. M. Breuer 7(0) 53-76, 1979
TitleThe interaction between surfactants and keratinous tissues
M. M. Breuer DOI: AbstractDuring cosmetic treatments, SURFACTANTS penetrate into KERATINOUS TISSUES (hair, skin and nails). Whereas some of these surfactant molecules migrate to the vital tissues, a considerable fraction remains bound to the keratin. The extent of binding depends both on the nature of the head group and the length of the hydrophobic tail of the detergent molecules. In addition to entering the amorphous region of the keratin, some of the detergents also penetrate into the crystalline microfibrils and change their structures affecting their tensile properties. Owing to an uneven distribution of detergent molecules in the tissues, an anisotropy of the elastic moduli will occur, resulting in considerable internal stresses which, in rum, might lead to a deterioration of hair, skin and nails. The chemical behavior of keratins is also influenced by the presence of absorbed detergent in their structures. Depending on the detergents and the conditions, these effects can be either protective or detrimental. The deposition of detergent molecules into keratin can be enhanced or diminished by the inclusion of appropriate ingredients into the product formulae. Key Words |
