Patent

CA 2625908

The invention relates to pharmaceutical, cosmetic, nutraceutical and food areas, in particular to compositions for coating tablets, capsules and other solid- or semisolid-form substances currently used in different application fields. More specifically, said invention relates to solid ready-for-use compositions for producing laminating solutions or dispersions for solid- or semisolid-form substances and is characterised in that the viscosity of said cold-regenerated solutions or dispersions is less than 1000 centipoises at a solid matter concentration greater than 20 %, wherein said viscosity is obtainable by using natural film-forming agents which are cold-soluble and exhibit a low viscosity in an aqueous medium at high concentrations.

La présente invention a trait au domaine pharmaceutique, cosmétique, nutraceutique et alimentaire et plus particulièrement à celui des compositions prêtes à l~emploi destinées à l~enrobage des comprimés, gélules, capsules et autres formes solides ou semi solides couramment utilisées dans ces différents domaines d~applications. L~invention concerne plus particulièrement des compositions solides prêtes à l~emploi destinées à la réalisation de solutions ou dispersions de pelliculage pour formes solides ou semi solides, remarquables en ce que la viscosité de ces solutions ou dispersions après reconstitution à froid, est inférieure à 1000 Centipoises, pour une concentration en matières solides supérieure à 20%, cette viscosité étant obtenue par l~utilisation d~agents filmogènes d~origine naturelle, solubles à froid et de faible viscosité en milieu aqueux pour de hautes concentrations.
