Evaluation of the content – containing interaction in cosmetic products using gas chromatography–mass spectrometry
ConclusionLa plastique est le matériel le plus utilisé en cosmétique de part sa diversité de forme et de couleur. La méthode en chromatographie gazeuse‐spectrométrie de masse a été validée et peut être utilisée pour l’évaluation de l'interaction contenu‐contenant des produits cosmétiques. Sur l'ensemble des tests réalisés sur 79 produits en contact avec 6 types d'emballage, le DEHP a été retrouvé à 90% pour les déodorants sticks et à 83% pour les parfums.

Influence of pH, concentration of sodium lactate as an additive and ultrasonic treatment on synthesis of zinc phosphate white pigments
Summary Zinc oxide that has the photocatalytic activity is used as a white pigment for cosmetics. A certain degree of sebum on the skin is decomposed by the ultraviolet radiation in sunlight. In this work, zinc phosphates were prepared from zinc nitrate and phosphoric acid at pH 5 and 7 with and without the addition of sodium lactate and ultrasonic treatment as a novel white pigment for use in cosmetics. The chemical composition, powder properties, photocatalytic activity, colour phase, moisture retention and smoothness of the zinc phosphates were studied. The obtained materials had a Zn/P ratio of about 1.5, which corresp...

Climbazole increases expression of cornified envelope proteins in primary keratinocytes
ConclusionClimbazole treatment of primary keratinocytes results in an upregulation in expression of a number of genes including those encoding proteins involved in cornified envelope formation with further studies demonstrating this did translate into increased protein expression. A climbazole driven increase in cornified envelope proteins may improve the scalp skin barrier, which is known to be weaker in dandruff. These studies suggest climbazole, besides its anti‐fungal activity, is delivering positive skin benefits helping to relive dandruff symptoms effectively.This article is protected by copyright.

Understanding the dandruff scalp before and after treatment: an in vivo Raman spectroscopic study
ConclusionThe in vivo Raman probe has allowed the direct measurement of dandruff‐affected skin in situ for the first time. It has been shown that the dandruff SC is different from that of the non‐ dandruff scalp and that it is changed by treatment with shampoo containing ZnPTO and brought towards the characteristics of non‐ dandruff scalp. It offers novel insights into how the nature of a healthy scalp should be defined.This article is protected by copyright. All rights reserved. (Source: International Journal of Cosmetic Science)

Physical characterization of titanium dioxide nanoparticles
ConclusionIn general, X‐ray line broadening, electron microscopy and surface area measurements led to estimates of the size of primary particles. By contrast, both sedimentation and light scattering measurements measured the size of the secondary particles, and the figures which were generated depended on the dispersion conditions used for preparation of the measurement samples. For poorly dispersed or lightly milled samples, the size may be dominated by the presence of weakly bound agglomerates, but even when the sample is well dispersed or heavily milled, the reported size cannot be less than that of the aggregates.

Characteristic differences in barrier and hygroscopic properties between normal and cosmetic dry skin.II. Depth profile of natural moisturizing factor and cohesivity
ConclusionOur results showed that, compared to normal skin, cosmetic dry skin had a lower NMF level across the SC depth and a lower cohesivity. Such results suggested that NMF levels are critical for cosmetic skin conditions, and lower NMF production may be associated with dry skin. In addition, the NMF level and its depth profile and the SC cohesivity are useful clinical end points for assessing the efficacy of dry skin treatments such as skin moisturizers.This article is protected by copyright.

The mixed surfactant was PEG‐7 glyceryl cocoate/PEG‐40 hydrogenated castor oil/glyceryl monooleate. The LLC formation and phase behavior were observed by polarized optical microscopy (POM) before and after MSE loading.
