Abstract

Cette invention concerne des procédés pouvant améliorer la solubilité de composés sensiblement insolubles dans l'eau, par combinaison desdits composés avec un polymère soluble dans l'eau, par exemple un polymère de polyoxyde d'alkylène ou un éther de cellulose, ayant un poids moléculaire compris entre environ 50 000 et 7 000 000 grammes par gramme dans une quantité effective pour améliorer la solubilité desdits composés dans l'eau, en milieu acide à un pH inférieur à environ 5, par exemple. L'invention concerne également des compositions contenant les composés ayant une solubilité dans l'eau améliorée.
