Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0021] The test reagent for hair quality testing provided by this invention has the following mass percentages of each component: alkali 0.12%-12.5%, oxidant 0.25%-15%, and the remainder is excipients.
[0022] Specifically, the alkaline agent is selected from at least one of ammonia, organic amine, and alcohol, wherein the organic amine is selected from ethanolamine, monoethanolamine, etc., and the alcohol is selected from aminomethylpropanol, etc.
[0023] The oxidant is selected from at least one of hydrogen peroxide, sodium perborate, potassium persulfate, and sodium bromate.
[0024] The mass percentages of each component in the excipients are as follows: surfactant 0%-5%, thickener 0%-5%, chelating agent 0%-1%, and the balance is deionized water.
[0025] In some embodiments of this application, the detection reagent further includes a mass percentage of 1×10⁻⁶. -5 The dye reagent is %-8%, and the dye reagent is selected from hair dyeing pigments, such as at least one of p-phenylenediamine, aminophenol, anthraquinone intermediates, benzene intermediates, naphthalene intermediates, and other benzene derivatives.
[0026] Specifically, the dye reagent is selected from aniline, p-phenylenediamine, o-phenylenediamine, p-phenylenediamine, anthraquinone, 1-aminoanthraquinone, nitrobenzene, p- or ortho-dihydroxybenzene, 2,6-dihydroxyethylaminotoluene, 4-hydroxy-2-aminotoluene, phenol, o-aminophenol, 2-amino-6-chloro-4-nitrophenol, 5-amino-6-chloro-o-cresol, 2-methyl-5-hydroxyethylaminophenol, 2-methylresorcinol, 4-chlororesorcinol, resorcinol, m-aminophenol, p-methylaminophenol, 3,4- One or more of the following: amino-m-cresol, p-aminophenol, m-aminophenol, p-aminophenol, naphthol, 2-naphthol, 2,4-diaminophenoxyethanol hydrochloride, 2,4-diaminophenoxyethanol sulfate, 2,6-diaminopyridine, 2-amino-3-hydroxypyridine, 2-amino-4-hydroxyethylaminoanisole sulfate, HC Yellow No. 2, N,N-bis(-hydroxyethyl)-P-phenylenediamine sulfate, 1-hydroxyethyl-4,5-diaminopyrazole sulfate, and 2,5-diaminotoluene sulfate.
[0027] Given the wide variety of dye reagents and their combinations, different dye reagents can be selected and mixed or used in different ratios according to the user's hair dyeing needs to obtain different colors. During hair quality testing, the dye reagent can penetrate into the hair and be oxidized by the oxidant to form large-molecule insoluble pigments, which are locked inside the hair to determine the color absorption capacity of the hair strand being tested.
[0028] In some embodiments of this application, the detection reagent further includes a mass percentage of 1×10⁻⁶. -5 %-2% antioxidant. The use of antioxidants can prevent the test reagents from oxidizing during storage. Sodium sulfite is selected as the antioxidant.
[0029] In some embodiments of this application, the detection reagent further includes a mass percentage of 1×10⁻⁶. -5 The oxidation inhibitor is %-2.5%. The oxidation inhibitor can slow down the oxidation process of the test reagent, so that the dye reagent can fully penetrate into the hair cortex and ensure the hair quality test effect. The oxidation inhibitor is sodium isoascorbate.
[0030] In some embodiments of this application, this application also provides an application of a test reagent for hair quality testing during the hair dyeing process. The test reagent is a commercially available hair dye. Preferably, the test reagent is a test reagent formulated with the above-mentioned proportions. The test reagent is in the form of water or emulsion, which allows it to easily and evenly contact and react with the hair strand of the sample to be tested when used for hair quality testing, so as to better highlight the hair quality characteristics of the hair strand of the sample to be tested.
[0031] The specific procedure for using this test reagent for hair quality testing is as follows:
[0032] The test reagent is reacted with the sample spring under conditions of 30℃-75℃ for 30s-15min to obtain the sample spring after reaction;
[0033] Obtain the hair quality information of the sample spring after the reaction, and obtain the hair quality condition of the sample spring after the reaction based on the hair quality information.
[0034] Specifically, when reacting the test reagent with the sample spring, the alkali and oxidizing agent are first heated to 30℃-75℃ respectively, then the components are mixed to obtain the test reagent, and finally the sample spring is immersed in the test reagent for 30s-15min; or, after mixing the components to form the test reagent, the test reagent is heated, and then the sample spring is reacted with the test reagent heated to 30℃-75℃ for 30s-15min; or, the sample spring is immersed in the test reagent, and the sample spring and the test reagent are heated to 30℃-75℃ while reacting. Heating can provide a suitable reaction environment for the reaction process, improve reaction efficiency, and better highlight the hair quality characteristics of the sample spring.
[0035] Before obtaining the hair quality information of the sample spring after the reaction, the reaction spring can be cleaned and dried. The cleaning process removes residual test reagents adhering to the surface of the sample spring, and the drying process reduces the influence of moisture on hair quality detection, so as to ensure that the obtained hair quality information is more accurate and is conducive to judging the hair quality of the sample spring.
[0036] When the test reagent is used to soak the sample hair strand, the alkaline conditions cause the cuticles on the surface of the hair strand to swell, and the oxidant penetrates into the hair strand, oxidizing the pigment in the hair strand and causing it to lose color. This allows for the detection of the pigment content and the ease with which the hair strand's color fades. Under the action of the oxidant, the dye reagent can be oxidized and coupled into large-molecule insoluble pigments, which are locked inside the hair, thus facilitating the detection of the hair strand's ability to absorb dye. By reacting the test reagent with the hair strand, various hair quality characteristics of the sample hair strand can be obtained, helping users to accurately determine their hair quality.
