Semipermanent or direct colouring includes any product capable of affecting to some extent a change in the natural hair colour that will last through at least five shampoo washings. Semipermanent dyes are simple and easy to use, as opposed to oxidation dyes, and are normally formulated for application on nonbleached hair. Following increases in supply of such formulations, we have started an analysis for quality control purposes of 21 commonly marketed dyestuffs (nitroaminobenzenes, anthraquinone and Arianor dyes) and 20 colouring products manufactured by four leading companies. By using TLC (silica gel and reversed phase) and HPTLC (silica gel) procedures we have determined relative retention values to 1,3-diamino-4-nitrobenzene of standards and dyes found in the commercial products. All the values reported (standards and samples) are the average of five analytical results (+/-SD). 相似文献

In this work, the effects of a new class of polymers generally used in hair and skin cleansing products, the SoftCAT (SofCAT SL and SoftCAT SX), on the dye uptake on the hair fibre and the fading effects has been studied. These polymers, based on quaternary ammonium salts of hydroxyethylcellulose, are cationic products that differ in viscosity, hydrophobic substitution index (HS) and/or cationic substitution (CS, % N). UV–Vis spectroscopy has been used to analyse the extracted dyes from the hair cuticle and the cortex. The results indicate that the presence of polymers in the dye bath improve both the quality of the dyeing process and the anti‐fading effect during the washing cycles. This phenomenon is postulated to be attributable to the polymers hydrophobically bonding with the dyes and so facilitating their increased penetration into the hair. 相似文献

A method for the identification and the quantification of direct dyes in semipermanent hair colouring cosmetics by using a reversed phase high-performance liquid chromatography (HPLC) with gradient elution and diode array detector (DAD) detection is presented. A standard mixture of 18 commonly marketed dyestuffs (11 nitroderivatives, two anthraquinones and five Arianor dyes) was studied. The major problems in the analysis of the mixture of direct dyes is the different chemical structure and especially the wide range of polarities. However we succeeded in the complete separation of the standard dyes. A qualitative analysis of eight colouring commercial products selected from different shades and a quantitative analysis of three of them was carried out. Materials, methods and results are reported. 相似文献

A number of the constituents of semi-permanent and permanent hair dyes have been shown to be mutagenic in bacteria, to induce mutation, chromosome breakage, sister chromatid exchanges and malignant transformation in mammalian cells, to cause mutation in Drosophila , to induce mitotic recombination in yeast and to induce tumours in rodents. Some hair dye ingredients and commercial dyes have been shown to give rise, in the urine of treated rats, to metabolites which are also mutagenic in bacteria.
The test systems used are briefly described and the data generated are reviewed. In addition, attempts to identify whether the hazards predicted from the laboratory studies present a risk to man either by epidemiological studies or monitoring of exposed populations are also discussed.

Many hair characteristics (e.g. color and curl) are genetically determined. Here, we investigated whether hair quality is also genetically controlled and related to differences in hair composition. Female, Caucasian subjects ( n = 292) were recruited into this study and segmented by self-perceived hair quality and by permanent colorant usage. Hair fibers were collected and characterized by amino acid analysis, dry tensile elastic modulus testing and two-dimensional electrophoresis of hair protein extracts.
Protein analysis revealed a string of 66 kDa proteins that correlated with hair of high quality. Loss of low molecular weight (14–29 kDa) proteins increased with colorant usage, particularly in hair of low quality. Amino acid analysis showed that the levels of serine and threonine across all the subjects followed bimodal frequency distributions suggestive of a genetic influence. Overall, data suggested that perception of quality was linked to high serine and threonine levels. In addition, where hair was colored, quality was associated with lower cysteic acid levels. Lower cysteic acid levels were not linked to lower colorant usage and our data suggest that high quality hair may be more resistant to colorant damage. Elastic modulus was significantly higher in hair of higher quality (4.65 GPa) compared to all medium and low quality hair combined (4.3 GPa), P < 0.02. This suggests a link between altered hair composition and mechanical properties. In conclusion, the composition and mechanical properties of hair have been linked to hair quality. We hypothesize that hair quality is thus likely to be genetically determined. Understanding of the links between hair composition and its properties could be utilized in the future for designing products targeted to each individual's hair make-up, and for producing diagnostic tools for determining hair quality. 相似文献

An analytical method has been developed that allows the determination of p-phenylene diamine derivatives in urinary samples collected from women after hair dyeing with commercial formulations. During an on-line flash hydrolysis of the urine, a number of metabolites of p-phenylene diamine were hydrolyzed to free p-phenylene diamine, which was then determined using gas chromatography-mass spectrometry. The excretion of metabolites of p-phenylene diamine could be followed during 24 or 48 hours after the dye had been applied. Most of the p-phenylene diamine cleaved by the flash hydrolysis procedure was, in fact, involved in the N,N'-diacetyl combination. The dose excretion for p-phenylene diamine as measured by this method was comparable to that found by other authors who made use of radioactively labelled material. The present analytical method can be used to evaluate procedures intended to decrease the percutaneous absorption of p-phenylene diamine. Thus, a five- to ten-fold decrease in its penetration was observed by protecting the scalp with clay before applying the dyeing composition. 相似文献
