Dexpanthenol und Psoriasis

The NCBI web site requires Dexpanthenol und Psoriasis to function. The current study presents Dexpanthenol und Psoriasis simultaneous quantification of dexpanthenol and resorcinol from marketed hair care formulation. Dexpanthenol is often present as an active ingredient in personal care products for its beautifying and invigorating properties and restorative and smoothing properties.

On the other hand resorcinol is mainly prescribed for the treatment of seborrheic dermatitis of scalp. The toxic side effects of resorcinol limit its use in dermatological preparations. Therefore an accurate quantification technique for the simultaneous estimation of these two components can be helpful for the formulation industries for the accurate analysis of their product quality.

The mobile phase flow rate was 0. The linearity study was carried out using five solutions Dexpanthenol und Psoriasis concentrations ranging between The method has been validated as per ICH Q2 R1 guidelines. The ease of single step sample preparation, accuracy, and Dexpanthenol und Psoriasis intraday and interday study presents the method suitable for the simultaneous quantification of dexpanthenol and resorcinol from any personal care product and dermatological preparations containing these two ingredients.

Dexpanthenol DP [D-panthenol or Provitamin B5] is the alcoholic analogue of D-pantothenic acid. Http://festival-celle.de/salbe-mit-vitamin-d-schuppenflechte.php it is 2,4-dihydroxy-N- 3-hydroxypropyl -3,3-dimethylbutanamide commonly present as an active ingredient in a number of Vitamin B-complex supplements and cosmetics creams, ointments, lotions, etc.

DP is absorbed through the skin and gets converted Dexpanthenol und Psoriasis its active form, pantothenic acid Vitamin B5the precursor for the biosynthesis of coenzyme A. The acid form plays an important role in Krebs Cycle [ 4 ]. Due to its Dexpanthenol und Psoriasis, smoothing properties and antidermatitis and depigmentation properties it http://festival-celle.de/fuer-wie-viel-behandelt-psoriasis.php often used in hair care products Dexpanthenol und Psoriasis 7 ] and some vitamin Dexpanthenol und Psoriasis. The next candidate under our study is resorcinol RC or benzene-1,3-diol.

It Dexpanthenol und Psoriasis got a number of pharmaceutical applications like treatment of acaine, seborrheic dermatitis, eczema, psoriasis, and Dexpanthenol und Psoriasis skin disorders. It is also used in hair coloring agents.

However, this molecule has got a number of side effects on long term use or in large dosage [ 89 ]. Research shows that a long term use of RC leads to this web page effects on human thyroid gland resulting in hypothyroidism [ 1011 ]. Therefore an exact method for the quantification of RC from formulations prescribed for medicinal and cosmetic use is essential.

Several cosmetic and pharmaceutical preparations contain both RC and DP either in form of excipients or as active Dexpanthenol und Psoriasis and very few methods have been reported for their quantification from such formulations.

Again most of the reported techniques present methods for either RC or DP. Most of the methods described for the quantification of RC are spectrophotometric techniques [ Dexpanthenol und Psoriasis13 ] and very few reported chromatographic techniques [ 14 — Dexpanthenol und Psoriasis ].

In another study conducted in our laboratory we developed a Dexpanthenol und Psoriasis for the quantification of RC only from a marketed hair care product using an isocratic elution technique using liquid chromatography [ 18 ]. This method is however not suitable for the Dexpanthenol und Psoriasis of DP from such formulation which inspired us for the development of this newer technique.

For DP only a single validated supercritical fluid chromatographic method has been reported [ 19 ]. The method describes the quantification of the active D-form in a racemic mixture of D and L forms of panthenol from cosmetic formulation using a mass spectroscopic Dexpanthenol und Psoriasis. In the current study a simple, rapid, precise, and validated technique for the simultaneous quantification of both DP and RC from a marketed hair care product, in presence of a complex matrix comprising glycerin, ethanol, biotin, keratin hydrolysate, hyalkyl HBU, nicotinic acid, and polyvinylpyrrolidone, is presented.

Dexpanthenol DP standard purity Hair care formulation containing DP and RC with batch number HV, manufacturing date FebruaryDexpanthenol und Psoriasis expiry date July was used as a representative marketed formulation for study.

Solvents of chromatography grade were purchased from Spectrochem India Limited. All reagents used in analysis were purchased from Merck India Limited. A Waters Dexpanthenol und Psoriasis Separation Module Waters, USA quaternary gradient system and Waters dual lambda absorbance detector Dexpanthenol und Psoriasis used for the quantification purpose.

The analysis was carried out using Empower 3 software Waters, USA. The mobile phase was a combination of filtered and degassed 5. Prior to chromatographic separation both the standard and the sample solutions were filtered through 0. The RC and DP stock solutions were prepared by dissolving Solution A was diluted to the range Peak area versus concentration curve was prepared Figure 1 a for RC and Figure 1 b for DP and was used for the determination of linearity of the method and the same was used for the quantification purpose.

The results were presented in Table 2 a and b for RC and DP, respectively. The curve fitting purpose was carried out following the least square method. Preparation of sample solution was critical when a number of link substances were present within the matrix like glycerin, ethanol, biotin, keratin hydrolysate, hyalkyl HBU, nicotinic acid, and polyvinylpyrrolidone.

However in our study, the method has been optimized following a simple Dexpanthenol und Psoriasis step sample preparation technique which was very much suitable for the regular analysis.

This solution was injected into the chromatographic system after filtering through 0. The high performance liquid chromatography technique for the simultaneous quantification of RC and DP Dexpanthenol und Psoriasis carried out following external calibration method [ 2021 ]. The analytical please click for source was validated on the basis of accuracy, precision, linearity, range, and robustness of the method.

The reliability Schnecke Achatina accuracy of the proposed method were determined on the basis of recovery studies. Precession of the method was studied on the basis of precession of six replicate injections of the standard solution.

The linearity was established through preparation of standard linearity curve in the concentration range of The same curves were used for quantification purpose. The intraday precision was calculated using six injections at the higher concentration range The peak purity study was used to determine specificity of the method. A photodiode array PDA detector was Dexpanthenol und Psoriasis for the purpose in place of UV-detector mentioned earlier, keeping the other chromatographic conditions unaltered.

The limit of quantitation LOQ and the Dexpanthenol und Psoriasis of detection LOD were determined following the technique described elsewhere [ 21 ]. Ruggedness of the Dexpanthenol und Psoriasis was determined by carrying out experiment on instruments of different make.

The result click to see more from each stage was subjected to statistical analysis based on Sigma plot software Version 8. The average runtime for analysis was 28 minutes and the average retention time for RC was 7.

This was probably the first reported technique for the simultaneous quantification of both from marketed hair care product. The chromatographic purity for each component was analyzed using a PDA detector for each component under consideration. The peak purity angle for RC and DP was 0. Thus the analyte peaks were symmetrical, pure, and spectrally homogeneous and there is sufficient resolution between Dexpanthenol und Psoriasis respective analyte peaks in the sample chromatogram Figures 3 b and 4 b.

The quantification of RC was carried out on the basis of peak area and for DP on the basis of Dexpanthenol und Psoriasis height. The method for analysis discussed earlier was validated as per USP and ICH Q2 R1 guidelines. The respective parameters for study were presented Dexpanthenol und Psoriasis follows. The suitability of the chromatographic system for performing the analysis was studied on the basis of system suitability.

It was usually represented in terms of column efficiency, resolution, capacity factor, and tailing factor. The peak asymmetry was usually expressed in terms of symmetry factor or tailing factor. Here value of Dexpanthenol und Psoriasis was assigned for a Dexpanthenol und Psoriasis symmetrical peak and the same increases with the increase in peak tailing.

For a perfectly symmetrical peak its value was unity and the same increases as the tailing becomes more pronounced. In order to study the linearity of the method, standard solutions in concentration range of 3.

The result obtained from the analysis was used to prepare the linearity curve. The limit of detection See more and limit of quantitation LOQ determined using the linearity curve [ 21 ] were 2.

The results explained the sensitivity of the technique within the range of analysis under consideration [ 22 ]. The accuracy was a measure of closeness of test results obtained by that procedure in comparison with the true value.

It is necessary to establish the accuracy of the procedure in concentration range under consideration. In this study the accuracy was analyzed on the basis of recovery study. The solutions were prepared by adding a known volume of the standard solutions solutions A and B to Foto Hals respective sample solutions.

The results presented a mean recovery of Therefore http://festival-celle.de/welche-art-von-krankheit-psoriasis.php appreciable accuracy was established over the range of study [ 2122 ].

In our study precession was established on the basis of the standard deviation or relative standard deviation of a series of measurements like repeatability and intermediate precession of the developed technique.

The same sample solution was injected in triplicate for three consecutive days and the result thus obtained was used to determine the intermediate precession. The unequivocal assessment of Psoriasis Vorrichtung Darsonval analyte under consideration from Dexpanthenol und Psoriasis mixture of components Dexpanthenol und Psoriasis impurities, degradation products, and matrix components was termed as specificity [ 21 ].

In this study specificity of both DP and RC was determined on the basis of chromatographic peak purity study of sample solutions.

A peak was considered spectrally homogeneous, that is, free from coelution, only when the peak purity angle was less than threshold.

The Dexpanthenol und Psoriasis presented the peak purity angle for RC and DP 0. Therefore it was concluded that the respective peaks were spectrally homogeneous, free from any coeluting impurities, and specific for the simultaneous analysis of both RC and DP.

The robustness was usually defined as the capacity of an analytical procedure to remain unaffected on introduction of small but deliberate variations of procedural Dexpanthenol und Psoriasis listed in the procedure documentation and present an indication of its stability during regular analysis. The robustness of the current method was studied on the basis of variations in analyst, instruments, and solution stability and on different storage conditions. The results were found within tolerance limits [ 2022 ] Table 5.

The current method was found to be robust for the simultaneous quantification of RC and DP Table 5 at concentrations as low Dexpanthenol und Psoriasis 6. The reverse phase high performance liquid chromatographic technique developed in the current study was simple in terms of sample preparation and analysis, sensitive and selective for the quantification of both resorcinol and dexpanthenol simultaneously, and precise and accurate for their simultaneous quantification from a complex matrix.

The method has been validated in terms of accuracy, precession, linearity, and sensitivity as per ICH Q2 R1 guidelines. The respective retention time for DP and RC was 3. The peaks were well resolved from each other and other closely eluting peaks. Thus the current method is suitable for routine analysis, stability testing, and simultaneous quantification of RC and DP from various formulations available in the market.
