Title (EN) COMPOSITIONS AND METHODS FOR DELIVERY OF MATERIALS
(FR) COMPOSITIONS ET PROCÉDÉS POUR ADMINISTRER DES SUBSTANCES
Abstract: front page image
(EN)Compositions for the controlled delivery of active ingredients, for example, drugs, cosmetic materials, and agricultural materials. The compositions include a multiplicity of particles, each of the particles comprising (1) a microstructure comprising a semicrystalline polymer which has a peak melting temperature, Tp, of at least 20°C, and (2) the active ingredient. The microstructure comprises (i) crystalline domains of the semicrystalline polymer, the crystalline domains being separate from each other, and (ii) amorphous domains of the semicrystalline polymer, the amorphous domains providing a multiplicity of tortuous paths between the crystalline domains. At least part of the active ingredient is present in the amorphous domains. One of many valuable uses for the compositions is to provide a coating on a seed, for example a coating containing one or more of an insecticide, a fungicide, a nutrient, a biotic, a growth regulator and an herbicide.
(FR)L'invention concerne des compositions pour l'administration régulée de principes actifs, par exemple, des médicaments, des substances cosmétiques et des substances agricoles. Les compositions comprennent une multiplicité de particules, chaque particule comprenant (1) une microstructure comprenant un polymère semi-cristallin dont la température de fusion maximale, Tp, est d'au moins 20 °C, et (2) le principe actif. La microstructure comprend (1) des domaines cristallins du polymère semi-cristallin, les domaines cristallins étant séparés les uns des autres, et (ii) des domaines amorphes du polymère semi-cristallin, les domaines amorphes formant une multiplicité de trajets tortueux entre les domaines cristallins. Au moins une partie du principe actif est présente dans les domaines amorphes. L'une des nombreuses utilisations avantageuses des compositions est la formation d'un enrobage sur une semence, par exemple, un enrobage contenant un ou plusieurs éléments parmi un insecticide, un fongicide, un nutriment, un facteur biotique, un régulateur de croissance et un herbicide.
