Title
(EN) COATING FILM FOR SKIN
(FR) FILM DE REVÊTEMENT POUR LA PEAU
(JA) 皮膚用被膜
Abstract
(EN)
A coating film is produced, which comprises a fiber layer applicable to the skin and comprising fiber assemblies and a liquid agent, wherein the moisture permeability of the coating film is controlled by adjusting the weight per unit area of the fiber assemblies and the permittivity of the liquid agent to specified ranges. A coating film for human skin which comprises a fiber layer, wherein the fiber layer comprises fiber assemblies each composed of accumulated water-insoluble polymer fibers each having a fiber diameter of 50 nm or more and less than 10000 nm and a liquid agent X present between the fibers and on the surfaces of the fibers in the fiber assemblies, the weight per unit area Q of the fiber assemblies is 0.08 to 1.0 mg/cm2 inclusive, and the liquid agent X has a weight per unit area P of 0.5 to 2.3 mg/cm2 inclusive and a relative permittivity of 1.0 to 27 inclusive, contains a component (a) that is an oil agent having a liquid form at 20°C and having a relative permittivity of 0.5 to 20 inclusive, and also contains a component (b) that is a polyol having a liquid form at 20°C and contained in the liquid agent X at a content of 50% by mass or less.

Un film de revêtement est produit, qui comprend une couche de fibres applicable sur la peau et comprenant des ensembles de fibres et un agent liquide, la perméabilité à l'humidité du film de revêtement étant contrôlée en ajustant le poids par unité de surface des ensembles de fibres et la permittivité de l'agent liquide à des plages spécifiées. L'invention concerne un film de revêtement pour la peau humaine qui comprend une couche de fibres, la couche de fibres comprenant des ensembles de fibres, chacun composé de fibres polymères accumulées insolubles dans l'eau ayant chacune un diamètre de fibre de 50 nm ou plus et inférieur à 10 000 nm et un agent liquide X présent entre les fibres et sur les surfaces des fibres dans les ensembles de fibres, le poids par unité de surface Q des ensembles de fibres est de 0,08 à 1,0 mg/cm2 inclus, et l'agent liquide X a un poids par unité de surface P de 0,5 à 2,3 mg/cm2 inclus et une permittivité relative de 1,0 à 27 inclus, contient un composant (a) qui est un agent huileux ayant une forme liquide à 20°C et ayant une permittivité relative de 0,5 à 20 inclus, et contient également un composant (b) qui est un polyol ayant une forme liquide à 20°C et contenu dans l'agent liquide X à une teneur de 50 % en masse ou moins.
