PEROXYGEN RELEASE COMPOSITIONS AND METHOD FOR PRODUCING THEM |
摘要 |
Stabilized peroxygen containing compositions are disclosed both in thickened viscous form and in dry form. The compositions contain newly synthesized calcium sulfate crystals that function as a thickener and stabilizing agent against metal catalyzed decomposition. The invention discloses a composition comprising 0.5 wt % to 50 % wt of hydrogen peroxide 2.0 wt % to 80.0 % wt of newly synthesized calcium sulfate crystals being of individual sheet or needle shape and water said composition having a viscosity of 200 cP to 20 000 cP. The invention further provides a process for making same comprising the reaction of a water soluble calcium containing salt with sulfuric acid or a salt thereof in an aqueous hydrogen peroxide solution at a reaction temperature of up to 80°C in a mixing apparatus followed by a concentration step in order to thicken into a stable viscous dispersion or paste containing at least 2 wt % and preferably 10 wt % to 15 wt % of CaSO4. The compositions are suitable for use as disinfectants as cleaning agents and in a variety of personal care pharmaceutical textile bleaching and industrial applications. |
