Definitions

  • the present invention relates to formulation components, such as organic catalyst compounds having increased stability, compositions and laundry methods employing such organic catalyst compounds. More particularly, this invention relates to organic catalysts compounds such as quaternary imine bleach boosting compounds, quaternary oxaziridinium bleaching species, modified amines and amine oxides, compositions and laundry methods employing such organic catalyst compounds.
  • Oxygen bleaching agents have become increasingly popular in recent years in household and personal care products to facilitate stain and soil removal. Bleaches are particularly desirable for their stain-removing, dingy fabric cleanup, whitening and sanitization properties. Oxygen bleaching agents have found particular acceptance in laundry products such as detergents, in automatic dishwashing products and in hard surface cleansers. Oxygen bleaching agents, however, are somewhat limited in their effectiveness. Some frequently encountered disadvantages include their lack of fabric color safety and their tendency to be extremely temperature rate dependent. Thus, the colder the solution in which they are employed, the less effective the bleaching action. Temperatures in excess of 60 °C are typically required for effectiveness of an oxygen bleaching agent in solution.
  • bleach activators typically perhydrolyzable acyl compounds having a leaving group such as oxybenzenesulfonate, react with the active oxygen group, typically hydrogen peroxide or its anion, to form a more effective peroxyacid oxidant. It is the peroxyacid compound which then oxidizes the stained or soiled substrate material.
  • bleach activators are also somewhat temperature dependent. Bleach activators are more effective at warm water temperatures of from about 40 °C to about 60 °C. In water temperatures of less than about 40 °C, the peroxyacid compound loses some of its bleaching effectiveness.
  • the present invention fulfills the need discussed above.
  • the present invention provides formulation components, such as organic catalyst compounds as defined by claim 1 having organic catalyst lifetimes of greater than 30 minutes, as determined according to the Test Protocol, disclosed hereinafter.
  • organic catalyst compounds are effective not only for a longer duration of time under lower temperature water conditions, such as the 20 °C temperature indicated in the Protocol, and lower temperatures, such as 5 °C, but also have a greater catalyst lifetime under higher temperature water conditions, such as greater than 40 °C up to about 60 °C or even higher temperatures, resulting in improved stability of the organic catalyst compared to the organic catalysts of the prior art bleaching systems.
  • an organic catalyst compound with an organic catalyst lifetime (OCL) of only 20 minutes at 20 °C, as determined according to the Test Protocol, disclosed hereinafter, will have an OCL of only approximately 2 minutes at 40 °C, whereas an organic catalyst compound with an OCL of 10 hours at 20 °C, as determined according to the Test Protocol, disclosed hereinafter, will have an OCL of approximately 1 hour at 40 °C.
  • an organic catalyst compound with an OCL of 40 minutes at 20 °C, as determined according to the Test Protocol, disclosed hereinafter will have an OCL of approximately 4 minutes at 40 °C..
  • the performance advantage of a lifetime of 1 hour at 40 °C, compared to 2 minutes at 40 °C, is apparent.
  • the performance from an organic catalyst compound with a lifetime of 4 minutes at 40 °C, compared to 2 minutes at 40 °C, may also be much greater, particularly if the stained fabric in need of laundering is added to the wash after the OCL of the organic catalyst of the prior art has expired (i.e. after 2 minutes).
  • the organic catalyst of the prior art will show no or little bleaching (lifetime expired), whereas the organic catalysts provided by the present invention (having 2 minutes of OCL left) will continue to demonstrate effective bleaching.
