Abstract
(EN)
Compositions having high bioadhesion, mucoadhesion and viscoelasticity, containing mixtures of synthetic polymers, such as polyvinyl alcohol and Polycarbophil, and of biopolymers, such as alginic acid, hyaluronic acid and dermatan sulfate, useful in the treatment of skin and mucosal tissues dryness and dehydration, and suitable as vehicles for active ingredients in percutaneous absorption.
(FR)
On décrit des compositions possédant une bioadhésion, une muco-adhésion ainsi qu'une viscoélasticité élevées, et comprenant des mélanges de polymères synthétiques, tels que l'alcool de polyvinyle et le Polycarbophile, et de biopolymères, tels que l'acide alginique, l'acide hyaluronique et le dermatan sulfate, ces compositions étant utiles dans le traitement de la sécheresse et de la déshydratation de la peau et des tissus muqueux, et appropriées en tant que véhicules destinés à des principes actifs dans l'absorption percutanée.
