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.

Transcriptional changes in organoculture of full‐thickness human skin following topical application of all‐trans retinoic acid
ConclusionLes résultats de la présente étude montrent que les explants humains de pleine épaisseur représentent un modèle préclinique précieux pour l'étude des effets des rétinoïdes dans la peau. In this study, we developed an organoculture of human skin to investigate the effect of topical applied all‐trans retinoic acid using a gene array approach. We could by using this approach confirm previous studies on genes activated by RA in keratinocyte monocultures and also provide new insights on genes that are relevant to RA‐activation in human skin. The results in the present study show this model represent a ...

Texture Analysis of Cosmetic/Pharmaceutical Raw Materials and Formulations
ConclusionsThe results include the analysis of water, glycerine, and mineral oil as well as aqueous solutions of thickeners such as Acrylates/C10‐30 Alkyl Acrylate Crosspolymer (Ultrez‐20 obtained from Noveon), and Carbomer. Solutions of common surfactants and complex surfactant formulations such as shampoos have also been investigated. The results, in the form plots of force as a function of time or distance, resulting from slow bi‐directional probe movement (submergence and de‐submergence) in the analyzed fluid, were interpreted by considering buoyancy, drag, and viscous drag force given by Stokes equation.

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.

Formulation of lyotropic liquid crystal containing mulberry stem extract: Influences of formulation ingredients on the formation and the nanostructure
This study focused on the formulation of lamellar lyotropic liquid crystal (LLC) loaded with mulberry stem extract (MSE). The formulation tested used two oils: n‐dodecane or tridecyl salicylate, a co‐solvent (propylene glycol) and a single (PEG‐7 glyceryl cocoate) or mixed surfactant system. 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. Nanostructure determinations on these formulations following MSE loading used small angle X‐ray scattering...

Immediate and extended effects of sodium lauryl sulphate exposure on stratum corneum natural moisturizing factor
ConclusionResults imply that NMF components derived from sweat and urea cycling are least impacted by SLS exposure whereas NMF components derived from degradation of filaggrin and/or other S‐100 proteins are most impacted. This implies the restoration of the processes responsible for S‐100 protein processing into free amino acids takes several days to return to normal. Further examination of the enzymes involved in S‐100 protein processing following barrier disruption would provide insight into the pathway(s) for NMF restoration during SC recovery.
