example 1

[0056] The following procedure was used to assess the relative reactivity of different potential catalytic activators with hydrogen peroxide: 10 mg of activator was filled into a 20-ml glass scintillation vial. Aqueous hydrogen peroxide (5 ml of 5% hydrogen peroxide solution) was charged to individual vials and the vials were vortexed slowly to provide mixing. The degree of bubbling and gas evolution was rated visually for approximately the first 10 minutes after the addition of hydrogen peroxide and was classified using the following scale (1-6), where lower numbers indicate greater reactivity: 1 = very intense ; 2=strong; 3=moderate; 4=little; 5=very slight; 6=none. Table 5 summarizes the results.

[0062] Tables 6 and 7 show the composition of Test Formulations A-R, which were used in Evaluations 1-96; unless otherwise noted, entries reflect the mass (mg) of the different ingredients used in the 1-L reactor beaker. Load metal containing activators to provide cleaning approx. 1.1x10 -5 The in-wash metal concentration in mol / L. The A350 entry represents the Mn-containing activator tris-mu-oxo-bis[(1,4,7-trimethyl-1,4,7- The mass of triazacyclononane) manganese] bis(acetate). when in When the specific concentration of Mn in the TRS KB2 formulation was not readily available, KB2 was loaded according to the manufacturer's recommendations (approximately 0.5%-2.0%). Take about 1.1 x 10 -5 mol / L to use the organic activator TAED.

Abstract

The present invention is directed towards cleaning composition and / or formulations of commercial cleaning products containing beneficial metallocarbene activators for peroxygen species. The cleaning compositions and / or formulations include a bleaching component comprising a peroxy compound and one or more activators present in an effective amount to activate the peroxy compound to accomplish bleaching or cleaning or oxidation. The activator is a metallocarbene of the general structure (XX'C)yMLn' where M represents a metal center, C represents the carbene carbon bound to the metal center, X and X' may be the same or different and may furthermore be part of a cyclic structure, Ln' represents one or more other ligands which mayor may not include one or more metal centers, and where y greater than equal to I.

Description

field of invention [0001] The present invention relates to peroxy bleach-containing cleaning formulations containing metallocarbene complexes which activate these bleaches in these cleaning formulations. These peroxygen compounds may include hydrogen peroxide or hydrogen peroxide adducts or hydrogen peroxide generators or peracids or peracid generators. The present invention also relates to bleach-containing cleaning compositions comprising metal carbene activators for peroxygen compounds. Background of the invention [0002] The effectiveness of the cleaning product is highly dependent on the formulation ingredients used and the amounts used. Metal carbene complexes have been found to activate peroxide species such as hydrogen peroxide. The present invention focuses on these formulation ingredients and compositions suitable for use with metal carbene activators and peroxide species, useful cleaning formulations and combinations of metal carbene activators and peroxide com...
