2. Description of the Related Art Differentiating the condition of hair is an essential item for evaluation of cosmetics for hair. Conventionally, such distinction of the condition of hair is a non-invasive method. There is only a sensory test by a panelist, and the other is that the smoothness index is measured by a method of invasively collecting hair and measuring the gloss level as a gloss index using a gloss meter, or by a friction tester. There are methods for measuring the resistance value. That is, in the discrimination of the state of hair, it has been desired to develop a method for performing discrimination in a non-progressive manner, a separate method, and a discrimination method having a quantitative property. In addition, there is a water content in the hair as a surrogate value for the state of the hair, which is a near-infrared absorption spectrum that does not use ordinary Fourier transform, and is analyzed from a dispersion-type near-infrared absorption spectrum using a diffraction grating. However, although it is known to be used as a substitute for the indication value of hair, the causal relationship between the properties of water and the condition of hair obtained by analysis of near infrared absorption spectra has not been examined. Further, a technique for performing a multiple regression analysis such as a PLS analysis or a multivariate analysis such as a principal component analysis on a spectroscopic analysis and a specific indication value to clarify the correlation is known, but it is close to the hair condition. No attempt has been made to perform multivariate analysis on the infrared absorption spectrum and distinguish the hair condition from the near infrared absorption spectrum. In addition, the hair condition such as gloss and smoothness has not been identified by multivariate analysis of near-infrared absorption spectrum, and the idea itself has not existed. The causal relationship between the gloss and smoothness of hair and the state of water present and the amount of water present was unknown at all.

BEST MODE FOR CARRYING OUT THE INVENTION The method for discriminating the condition of hair according to the present invention comprises:

As the near-infrared absorption spectrum used for such an index or discrimination, any of a spectrum by a dispersion type using a normal diffraction grating, a spectrum by a device using a diode array, and a spectrum obtained by Fourier transforming these can be used. is there. More preferable is a spectrum obtained by further Fourier transforming a spectrum obtained by a dispersion type apparatus, a spectrum obtained by a diode array detector,
An example is a spectrum obtained by further Fourier transforming the spectrum obtained by the diode array detector. Here, although it is a multivariate analysis, the multivariate analysis is a method of associating and analyzing the relationship between chemical properties such as spectral data and characteristic values such as physical properties by a metrological process. Regression analysis or principal component analysis is known. Of these, PLS analysis can be preferably exemplified as the multiple regression analysis. This PLS analysis is based on the fact that, with respect to a continuous change in a factor such as wavelength in a specific sample, the spectral spectrum pattern in which a variable such as absorbance appears and a certain rational value of the sample. It is established as a technique for analyzing the change in variables for each rational value and each factor when analyzing the relationship between. In the principal component analysis, in the same analysis, the first principal component contributing to the fluctuation is analyzed, and then the second principal component axis orthogonal to the first principal component axis is analyzed, and the two principal components are analyzed. It is a method of comparing and estimating physical properties by changing the pattern in the coordinates formed by the component axes. Multivariate analysis such as PLS analysis or principal component analysis can be performed using commercially available software. As software for such multivariate analysis, for example, Pirowet (PIROUTET) sold by GL Sciences, Inc.
T), software sold by Cybernet Systems Co., Ltd., matlab (MATLAB) Yokokawa Electric Co., Ltd., Unscrambler II (Unscranbler II), Sepanova (SIMCA) sold software such as SIMCA Can be illustrated.
In addition to these, an algorithm called SIMCA can be added. Such algorithms are often embedded in the software,
This is useful for displaying principal component analysis. When these software are used to analyze the near-infrared absorption spectrum and the result is used in the discrimination method of the present invention, the general processing steps are as follows. At this time, the Fourier transform near-infrared absorption spectrum used may be the original spectrum obtained by measurement, or may be the one obtained by processing the original spectrum. As a data processing method, for example, a multi-order differential value such as a second-order differential value or a third-order differential value can be preferably exemplified. Of these, the preferable one is the original spectrum or its second derivative. Thus, there is a good correlation between the condition of the hair and the Fourier transform near infrared absorption spectrum of the hair when analyzed.

Thus, the spread of the second derivative of the Fourier transform near-infrared absorption spectrum of the hair used for preparing the calibration curve is plotted on the prepared calibration curve, or the rational value is plotted on the second derivative axis. It is possible to know the relationship between the second derivative of the Fourier transform near-infrared absorption spectrum of hair and the rational value of the state of the hair, and the Fourier transform near-infrared absorption spectrum of the hair of the test sample. In PLS analysis, the plot of the second derivative of the wavelength at which the plot is identified as being relevant can be compared with these to calculate the plot of the test sample hair. At this time, a group representative value such as a median or an average value of the secondary differential values of the plot of the hair used for creating the calibration curve was simply plotted on the calibration curve or on the secondary differential value axis, and the test sample was prepared. It is also possible to plot the group representative values of the second-order differential values of the hairs and compare the group representative values with each other to calculate the rational value. Here, it should be noted that by measuring one Fourier transform near-infrared absorption spectrum, the friction feeling according to the discrimination method of the present invention,
That is, it is possible to calculate a number of positivity values of the state of the hair such as the degree of gloss (gloss) and the sensory value. In other words, it is possible to perform multifaceted evaluation of the state of the hair from one measurement result.

<Example 1> 3 prepared in different states
The gloss value of each kind of hair was measured with a gloss meter. Hair in different states was prepared by treating the hair with different concentrations of thioglycolic acid. The adjustment method is shown below. At the same time, the Fourier transform near-infrared absorption spectrum (wavelength: 4700 to 5000 cm −1) of this hair was measured, and the second derivative was performed. For the gloss value and the second derivative, PLS analysis was performed using Unscrambler II, and a calibration curve was prepared by PLS analysis. The calibration curve is shown in FIG. Than this,
It can be seen that there is a good correlation with the gloss value by the gloss meter. When plotting the gloss value on the calibration curve, a block is formed for each gloss value, and by using this calibration curve, the gloss value can be calculated from the Fourier transform near infrared absorption spectrum of the hair of the test sample. I understand. Further, the high correlation coefficient shows that the discrimination method of the present invention is excellent in quantification.
