Definitions

  • the present invention relates to the field of coated particulate detergent components or compositions.
  • GB-A-1 395 006 published on 21st May 1975, discloses cellulosic polymers as coating agents for detergent components. Sucrose and glucose are also disclosed therein, as plasticizers with dextrin. However cellulosic polymers and sugars are nowhere disclosed in combination as coating agents for detergent components.
  • the disadvantage of coating a detergent with cellulosic polymer on its own is that the film formed is slow to dry, and can form a coating that is sticky.
  • the object of the present invention relates the application of certain coatings to particulate detergent components or compositions to improve free-flow properties, improve dispensing, avoid dust formation and improve stability of storage sensitive materials.
  • a further object of the present invention is to provide a fast-drying coating which forms a continuous film around the particles of the detergent component or composition.
  • the object of the invention is achieved by a two-step coating process, wherein the first coating step comprises the process of mixing the detergent composition or component with a finely divided particulate material which is preferably aluminosilicate, and the second coating step comprises the process of applying a coating agent.
  • Suitable coating agents comprise from 5% to 95%, preferably from 10% to 60% by weight of cellulosic polymer; from 5% to 95%, preferably from 60% to 90% by weight of sugar; and optionally, from 0% to 30% by weight of plasticizer.

  • the components of the second coating agent are dissolved or dispersed in a suitable solvent or carrier medium.
  • a preferred solvent is water, and an aqueous solution may be prepared which is typically 5% to 40% solids.
  • the solution or dispersion may then be sprayed on to the detergent component or composition.
  • the proportion of the second coating agent needed to provide a suitable coating layer depends on various parameters, such as the surface characteristics of the detergent component or composition, and will be easily determined by experiment.

Abstract

Cette invention se rapporte à l'application de certains enrobages à des compositions ou des composants détergents sous forme particulaire, dans le but d'améliorer les propriétés d'écoulement libre du produit, d'en améliorer la distribution et d'éviter la formation de poussière. On réalise ces objectifs grâce à un procédé d'enrobage en deux phases, la première phase d'enrobage consistant à mélanger la composition ou le composant détergent avec un matériau particulaire finement divisé, qui est de préférence de l'aluminosilicate, et la seconde phase d'enrobage consistant à appliquer un agent d'enrobage. Les agents d'enrobage appropriés renferment de 5 à 95 % en poids d'un polymère cellulosique, de 5 à 95 % en poids de sucre, et, éventuellement, de 0 à 30 % en poids d'un plastifiant.
