  • the bleach dispersion is produced by using the optical brightener (s) as a moist press cake or dry powder with one or more peracids or peracid-forming systems together with water and possibly other additives mixed and homogenized.
  • the bleach dispersion thus obtained is for months stable and does not sediment.
  • the optical brightener can be incorporated without visible sedimentation and its After neutralizing the oxidizing agent with hydrosulfite, the amount is determined spectroscopically to 100% of the amount used. The dispersion obtained is stable.
  • the bleach dispersions according to Examples 1 and 2 are at 14 days stored at a temperature of 20 ° C in the dark. When determining the Optical brightener content in both cases results in a content of 100% of the Baseline.
