Rinse-added fabric softening compositions are provided comprising mixtures of a diester quaternary ammonium fabric softener material, a highly ethoxylated hydrophobic material as a scum dispersant, and a liquid carrier. This mixture prevents the formation of scum caused by the interaction of the diester quaternary ammonium fabric softener material with anionic detergent surfactant and/or detergency builder entrapped in the fabric. These, preferably biodegradable, compositions have good product stability, dispersibility, and concentratability, as well as excellent fabric softening characteristics.
La présente invention porte sur des compositions adoucissantes pour tissus, à ajouter lors du rinçage, comprenant des mélanges constitués d'un agent adoucissant à base d'un diester d'ammonium quaternaire, d'une substance hydrophobe fortement éthoxylée servant à disperser la saleté et d'un support liquide. Ces mélanges préviennent la formation de saleté causée par l'interaction de l'agent adoucissant pour tissus à base d'un diester d'ammonium quaternaire avec le surfactant détergent anionique et/ou l'adjuvant de détergence piégé dans le tissu. Ces compositions, de préférence biodégradables, possèdent de bonnes caractéristiques de stabilité, de dispersibilité et de concentrabilité, ainsi que d'excellentes caractéristiques d'adoucissement.
