Titre : Sensory evaluation of moisturizing creams : combination of descriptive analysis panel test and preference test Type de document : texte imprimé Auteurs : So-Yeon Sim, Auteur ; Soo-Jeong Jeong, Auteur ; Bo-Kyoung Sun, Auteur ; Seong-Joon Moon, Auteur ; Ih Seop Chang, Auteur Année de publication : 2002 Article en page(s) : p. 19-23 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Sensory evaluation' 'Moisturizing cream' 'Trained panel' Consumer Preference 'Descriptive analysis' 'Preference testing and principal component Index. décimale : 668.5 Parfums et cosmétiques Résumé : The two most important factors that are perceived by consumers using cosmetic products are the biological or clinical effect and the sensorial effect. For repeated use of a product, its skin feel must be pleasant and comfortable to the user. As the skin feel of a product depends on the user’s sensation, the sensory evaluation is indispensable to measure and analyze its characteristics. Therefore, quantitative and descriptive sensory evaluation measuring the intensity of the characteristics and consumer’s preference evaluation are both required, and its desirable to correlate them.
We selected women through discriminative and descriptive tests to form a trained panel. They described the skin feel using various creams and emulsions, and sorted out the terms through discussion to decide the evaluation terminology and the definition of each term. Then, they were trained to remember the intensities of the reference materials’ characteristics. Under the same test condition, moisturizing creams were tested by the same test method.
The statistical analysis of the collected data showed that the principal components of the feel of these moisturizing creams were residuary factor and spreadability factor, and according to the results, the products were positioned in a 2-dimensional space. We also selected several creams among the tested products to run a preference test by consumers of various skin types and ages.
As a result, we subdivided the preferred skin feel of the moisturizing cream according to the skin type an the age of the consumer. With the descriptive sensory evaluation and the preference test results, we proposed the desirable skin feel of the moisturizing cream corresponding to the consumers’ skin type and age.

Titre : Sensitive skin syndrome in Portugal - A concise (social and demographic) characterization of the portuguese reality Type de document : texte imprimé Auteurs : Luis Monteiro Rodrigues, Auteur ; Lucilia Diogo, Auteur Année de publication : 2009 Article en page(s) : p. 107-110 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Sensitive skin' 'Skin susceptibility' 'Social-demographic features' 'Descriptive study' 'Portuguese market' Index. décimale : 668.5 Parfums et cosmétiques Résumé : Reports from global markets suggest that the sensitive skin syndrome affects 50 % of the population. Since there is currently no information on this condition in a small market like that in Portugal, the authors designed this descriptive cross-sectional study to characterize this syndrome in this particular context.
Data was collected using a structured questionnaire in the community pharmacies chosen for the study. 333 questionnaires (n=333) were validated, and 46 % of the surveyed individuals described their skin as "sensitive". Responders were predominantly women, the face was the most frequently mentioned area of the body affected, and environmental factors and contact were reported as the main causes of sensitivity. A wide in responses to irritation and in the relationship with previous pathological conditions was also found. Thus, the social and demographic pattern found here agrees with patient-type profile previously reported for the sensitive skin syndrome.Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=6100
