Definitions

  • the present invention relates to a fluorescent whitening agent formulation and, in particular, to a liquid fluorescent whitening agent formulation comprising a solution of a fluorescent whitening agent in a specific type of nonionic surfactant.
  • aqueous slurry containing the various components of the detergent composition, including a fluorescent whitening agent.
  • the detergent manufacturers prefer to use the fluorescent whitening agent component in the form of a liquid formulation, in order to facilitate the incorporation of the fluorescent whitening agent into the slurry to be spray-dried.
  • fluorescent whitening agents are often supplied to the detergent manufacturers in the form of an aqueous slurry.
  • Such aqueous slurries of fluorescent whitening agent usually contain large amounts of water, which must be removed during subsequent spray drying, and are often beset by problems, such as the formation of clumps during spray-drying, as well as instability to sedimentation on storage.
  • liquid formulations of fluorescent whitening agents which use organic solvents and are substantially anhydrous (e.g. FR-A-2654123, EP-A-0703293). These liquid formulations, however, are usually highly viscous and need to be incorporated into the detergent powder by means of special mixing techniques.
  • US-A-3,953,380 discloses liquid detergent compositions comprising fluorescent whitening agent at 0,5-5%, 40-75% non-ionic detergent and 5-35% water.
  • anionic fluorescent whitening agents are soluble in a mixture comprising a predominant amount of a certain type of nonionic surfactant and a lesser amount of water, to provide stable, clear solutions of low viscosity.
