StatistiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Skin gloss is a parameter of beauty and health and is used to evaluate the efficacy of makeup or skin care products. Skin gloss is a perception-based characteristic, which yet needs to be evaluated quantitatively and objectively. This study aimed to investigate the factors affecting the perception of matte, glossiness and greasiness on Korean women's skin, focusing on the effect of surface reflection.
- Methods : In this study, a visual evaluation of skin gloss was performed using modulated images that combined facial reference (normal) images with images characterized by 64 different levels of surface reflection to investigate factors that might affect the perception of matte, glossy and greasy skin. Fifteen participants classified the respective images into three categories (matte, glossy and greasy), and the intensity of each image was rated using a three-point scale (weak, moderate or strong). A multinomial logistic regression analysis was performed using 960 data points (n = 64 × 15). A high-frequency average + 1 standard deviation (SD = 4) was set as the criterion for a highly glossy object.
- Results : A significant difference was found between the three categories considering four parameters: low-frequency mean (LFM) and SD (LFSD) and high-frequency mean (HFM) and SD (HFSD). The results of the multinomial logistic regression analysis showed that LFM and HFSD were significant influencing factors for perceiving matte, glossiness and greasiness. As the LFM and HFSD of the images increased, perception changed from matte, to glossy and greasy. Further, the total number and total area of highly glossy objects were significantly different among the three categories.
- Conclusion : We identified four different factors related to perceiving matte, glossiness and greasiness on the faces of Korean women, including the LFM and HFSD of surface reflection, as well as the number of highly glossy objects and the area of surface reflection. Furthermore, we identified evenness of shine as a key factor for the perception of greasiness. These parameters could be useful for distinguishing skin gloss and for a quantitative evaluation of greasiness.Note de contenu : - MATERIALS AND METHODS : Ethical considerations - Stimuli image preparation - Image analysis - Questionnaire assessment - Data analysis

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : This study reviewed 155 journal articles that examined the adverse effects of textile dyes on human health. The distribution of these articles was investigated in terms of journal type, year of publication, methodologies and research contexts. Based on the use of citation network analysis, an objective approach for identifying clusters of articles in the literature, three major research domains of textile dyes on human health issues were found, dermatological effect, toxicological effect and respiratory effect. Further investigation was done by conducting a Main Path Analysis of the articles to draw a map of knowledge structure within each research domain. Finally, future research opportunities and directions were proposed for each research domain from a human health perspective. Note de contenu : - EXPERIMENTAL

StatistiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : Until now, standardized evaluation of cosmetic effects was conducted mainly in still conditions such as pictures. In real life, the consumers' experience of their cosmetics' effects is dynamic and some of the benefits can be better observed under movement. In order to capture motion-related performance of cosmetics, we developed a video-based paired comparison on an online platform.
- Methods : We validated this new tool through the evaluation of eyeshadow with high light reflection and colour gradation, especially visible under motion according to the observer point of view. This formula was compared with two marketed benchmarks. The three products were applied sequentially on the eyelid of eight Japanese women. Videos were taken in standardized light, speed and face position with a rotating camera around the face. The videos were uploaded on an online secured platform and eyelid 3D effect, highlight and colour gradation were evaluated through paired comparison test by 60 Japanese women from home on their PC or tablets. Those results were compared with picture-based paired comparison by the same observers.
- Results : Video-based paired comparison provided higher discrimination of products compared to picture-based comparison.
- Conclusion : As compared to still camera acquisition, the evaluation of cosmetics based on videos is closer to real-life experience and can bring higher discrimination, especially for motion-related attributes.Note de contenu : - MATERIALS AND METHODS : Methodology - Subjects - Makeup application - Video and picture recording - Online evaluation system - Raters - Test flow - Statistical analysis

StatistiquesIndex. décimale : 668.5 Parfums et cosmétiques Résumé : - Objective : This article measures and discusses the effects of different shower gels on the consumption of water used during a shower.
- Methods : A sensory panel was created for quantifying water consumption associated with the use of shower gels. Fifteen French panellists were recruited (age: 59 ± 7, height: 163 cm ± 9 and weight: 68 kg ± 20) and trained to assess rinsed skin in a standardized way. Effective panellists were then asked to assess 25 shower gels covering the variety of existing products on the market.
- Results : Results showed that the average volume was 4.77 L for heating the water and wetting the body and 4.15 L for rinsing the shower gel off the full body. We observed a significant shower gel effect (p < 0.0001) with the water volume needed to rinse the 25 shower gels ranging 3.21 L to 5.65 L.
- Conclusion : This paper demonstrates the impact of shower gel formulation on water consumption during a shower. It thus demonstrates the importance of formulating shower gels to reduce the total amount of water needed to shower. It also introduces the distinction between ‘useful water’ which refers strictly to the volume of water objectively needed to rinse off a product and the ‘used water’ which refers to the total shower volume of water. This distinction helps to better strategize actions in order to reduce water consumption from rinse-off cosmetic products used during showers.Note de contenu : - Context of using shower gel
