DRY COLOUR SYSTEMS AND METHODS AND EASILY DISPERSIBLE FORMULATIONS FOR USE IN SUCH SYSTEMS AND METHODS |
摘要 |
A dry pigment paint system includes dry pigment doses that may be used alone or combined with other dry pigment doses to provide a desired colour when dispersed in a paint base. The system may use a plurality of dry pigment formulations, with each dry pigment formulation consisting of one or more dry pigments, generally a plurality of dry pigments. Each dry pigment dose may include a single dry pigment formulation. Each does may be a tablet, capsule or sachet. Various dose forms and dispensing systems are disclosed. Formulations of easily dispersible (ED) pigments comprising a combination of a carboxylic acid polymer and a non-ionic alkoxylated surfactant are also disclosed. The combination is used in the formulation of a plurality of pigments. The formulations are suitable for mixing with a base medium at the point-of-sale (PoS) or by the end user. |

1) A dry pigment formulation dose form consisting essentially of two or more walls defining an interior volume and an amount of a dry pigment formulation contained in the interior volume where the dry pigment formulation is a spray dried particulate dry pigment formulation consisting essentially of one or more pigments and 0.5 to 3.6% (w/w) hydroxylated amine, 0.56 to 4.52% (w/w) acrylic acid polymer and 4.5 to 37.7% (w/w) ethylene oxide-propylene oxide diblock copolymer. |
