摘要： A composition of certain dyes with a category-2 hair bleach can simultaneously lighten hair up to seven levels and deposit various shades of color in a single step. The dyes are bleach-stable derivatives of azo, triarylmethane, thiazine, or nitro dyes. When linked at the ortho- and/or para-positions relative to the chromophoric centers and auxochrome groups located on or attached to the aromatic rings of these dyes, deactivating or weakly activating chemical groups enhance the dye stability in the alkaline bleach. The absence of ortho and/or para positioned deactivating or weakly-activating substituents, or the presence of strongly activating groups in these positions render the dye molecule susceptible to attack by the bleach and the eventual destruction of these dyes. These deactivating and protective chemical groups may be nitro, halogen, cyano, carboxyl, sulfonic, alkyl or aromatic groups, but not amino, hydroxy, alkoxy or alkylamide groups.

摘要： The condition of hair or other keratin fibers can be evaluated by measuring the force required to obtain a first value of elongation of the fiber in the yield region of the force-elongation curve, and the force required to obtain a second value of elongation of the fiber in the yield region. The ratio of these two measured forces is then determined as a damage index for the fiber. It is found that a constant force ratio is obtained for wet virgin keratin fiber independent of fiber diameter or the source of the fiber. It is also found that the force ratio changes as a function of subjective or objective measures of chemical damage to the hair fiber. The force ratio or damage index can, therefore, be used for identifying hair care products suitable for application to the hair without inducing unacceptable damage. The tests may be performed with simple tensile testing apparatus without tedious examination of the hair under a microscope.
摘要翻译：毛发或其他角蛋白纤维的状态可以通过测量在力 - 伸长率曲线的屈服区域中获得纤维的第一伸长率值所需的力，以及获得第二伸长率值所需的力纤维在产量区域。然后将这两个测量的力的比率确定为纤维的损伤指数。发现与纤维直径或纤维来源无关的湿原始角蛋白纤维获得恒定的力比。还发现力比随着对头发纤维的化学损伤的主观或客观测量的变化而变化。因此，力比或损伤指数可用于鉴定适用于头发的护发产品，而不引起不可接受的损伤。可以用简单的拉伸试验装置进行试验，而不用在显微镜下对头发进行繁琐的检查。
