Abstract
(EN)
Disclosed herein are compositions that can form a covering, layer, film, device, and/or prosthetic skin that can be comfortably worn to provide skin barrier function, skin hydration and therapeutic and aesthetic benefits. Provided herein are novel compositions that have low tackiness and form quickly, resulting in a wearable, comfortable (maintains temperature and humidity), breathable, thin, optically invisible, cosmetically elegant, flexible, stretchable, elastic and body-movement conforming, yet long-lasting covering, layer, film, device, and/or prosthetic skin on the skin or any other body surface. Provided herein are novel compositions that can form a covering, layer, film, device, and/or prosthetic skin that works for extended periods in excess of about 24 hours, while retaining function during and after exercising, showering and swimming (in sea-water, fresh water and chlorinated water), steam room (heat at high humidity), and sauna (heat at low humidity).

La présente invention concerne des compositions qui peuvent former un revêtement, une couche, un film, un dispositif et/ou une peau artificielle, pouvant être portés confortablement pour assurer une fonction de barrière cutanée, d'hydratation cutanée, ainsi que pour procurer des bienfaits thérapeutiques et esthétiques. La présente invention concerne de nouvelles compositions qui présentent une faible adhérence et se forment rapidement, permettant d'obtenir un revêtement, une couche, un film, un dispositif et/ou une peau artificielle pouvant être portés sur la peau ou toute autre surface du corps, qui épousent les mouvements du corps, sont élastiques, étirables, souples, cosmétiquement élégants, optiquement invisibles, minces, respirants, confortables (en maintenant la température et l'humidité) et néanmoins durables. La présente invention concerne de nouvelles compositions qui peuvent former un revêtement, une couche, un film, un dispositif et/ou une peau artificielle qui fonctionnent pendant des périodes prolongées dépassant environ 24 heures, tout en conservant leurs propriétés pendant et après l'exercice, une douche ou une séance de natation (dans l'eau de mer, l'eau douce et l'eau chlorée), un hammam (chaleur et humidité élevée) ou un sauna (chaleur et humidité faible).
