Illustrative example compositions that were produced include those set forth below. Exemplary exemplary compositions particularly demonstrate preferred embodiments of the invention as well as preferred weight percentages as well as preferred relative weight / weight ratio ratios with respect to the respective individual constituents present within the composition, EXAMPLES Examples of hard surface treatment compositions containing inventive peroxygen are described in the following "Table 1: the constituents indicated in Table 1 used for the production of the formulations were used in a base" as supplied "; of these constituents are described in more detail in Table 2. The treatment compositions containing peroxygen were produced by mixing the constituents in water as summarized in Table 1 in a beaker at room temperature which was stirred with water. A conventional magnetic stirring bar or shovel mixer, the agitation continued until the formulation was homogeneous in appearance.-It should be noted that the constituents can be added in any order, but it is preferred that a first premix be made. of any fragrance constituent with one or more surfactants in an aliquot of water used in the hard surface treatment compositions that - they contain peroxygen. The order of addition is not critical, but good results are obtained where the surfactants (which can also be the premix of the fragrance and the surfactants) are produced before the addition of the remaining constituents to the water. Preferably also the peroxygen compound, in particular, is then added to the hydrogen peroxide constituent. The amounts of the named constituents are indicated in% w / w based on the total weight of the hard surface treatment composition containing peroxygen of which it forms a part.

All of the constituents in the compositions in Table 1 above are indicated as a percentage by weight, and each composition comprises 100% by weight1. The. individual constituents were used, "as supplied" from their respective source and unless otherwise indicated, each of the constituents are to be understood as being "100% by active weight". . Deionized water was added in sufficient quantity, "es." 'to provide the balance up to 100% by weight of each of the examples and comparative example compositions. The additional identity of, and the sources of the constituents used in the formulations in Tables 1 are described in the following Table 2.

Each of the above compositions of Table ··· 1 was applied to a respective weight ratio of a composition of example: pretreated wipe (cleaning substrate) of 4: 1. The substrate of. used cleaning was a non-woven wipe (having a mass of 50 grams / m2) formed of spun polyethylene terephthalate fiber, the fibers of which have been treated with a finished composition to coat the fibers prior to the wipe formation. The spinning finish. was an aqueous composition, particularly Accosoft® 501 (Stepan example) which is described to contain 3% by weight of methyl bis (tallow amidoethyl) -2-hydroxyethyl ammonium methyl sulfate / and 2% by weight of an alkoxylated oleic acid . The spin finish was applied to the fibers, which are then formed into an article of. wipe, where the methyl sulfate. of methyl bis: (tallow amidoethyl) -2-hydroxyethyl ammonium and oleic alkoxylated acid comprises about 0.03%. eh weight of the wipe, before the application of the example composition in the respective weight ratios identified above.

Additionally for use as a "comparative" example of an article of wipe, the additional wipe articles formed of PET fibers of the spin finish are used in the articles according to the invention, however where a spin finish different was applied as the finishing composition '. This comparative example applies a spin finish which is great. aqueous part, but includes 1.4%. by weight of polyethylene glycol, 1% by weight ethylene glycol terephthalate esters and 0.1% by weight of an amphoteric surfactant. Notably, in. this comparative example, methyl-bis (tallow amidoethyl) -2-hydroxyethyl ammonium methyl sulfate was not applied present in the wipe. Subsequently the composition according to Table 3 was applied to a respective weight ratio of a composition of example: pre-treated wipe (cleaning substrate) of 4: 1.

The wipe articles were tested and evaluated according to one or more of the following test protocols.

Storage Stability Evaluation of Hydrogen Peroxide Samples of the compositions of Table 1 and Table 2 as well as., Wipe articles formed using these compositions were tested for their retention of hydrogen peroxide under storage conditions in a temperature range. The plural aliquots of each of the liquid compositions were stored in flasks with. White HDPE samples and during the duration of the test a small amount of the aliquot was removed and then analyzed to determine the% by weight of the hydrogen peroxide present .. A vial of the simple sample of. each of the compositions was used and maintained at each of the test temperatures, which are indicated in the following Table '4.. Additionally an adequate amount of each of the. compositions of Table 1 were applied to a plurality of rolls of pretreated wipe articles formed of 28 contiguous sheets of individual wipes of .17.78 cm (7 inches) per. 20.32 .cm (8 inches), which were joined at opposite edges by a perforation, whose perforations facilitate the separation of. each roll wipe. Each roll of the pretreated wipe articles were formed of 100% polyethylene terephthalate fibers, having a mass of 50 grams per square meter of area, and one of the individual compositions of El-E5 was loaded in a ratio of composition 4: 1 mass: wipe. It is noted that the .E.E4 compositions have been applied to detergent articles which have been pretreated with a finishing composition comprising methyl bis (tallow amidoethyl) -2-hydroxyethyl ammonium methyl sulfate, and . the wipe article has a load of approximately 0.03% on. wipe weight, before applying the composition. for example, while the "comparative" wipe article was formed by the application of composition | E5 in a 4: 1 mass ratio of composition: wipe, whose wipe substrate has been pretreated with a finishing composition that was largely watery, but includes 1.4% by weight of polyethylene glycol, 1% by weight of ethylene glycol terephthalate esters and 0.1% by weight of an amphoteric surfactant. From there, each of the rolls of the wipe articles was supplied to individual polymer cans which. They have a polymeric lid that fastens whose lid includes a sealable through opening. from which the wipes can be removed from the roll in a sequential manner ..

. Sample bottles containing aliquots of the compositions. as well as a plurality of sealed cans containing the preimpregnated wipe articles as formed above were stored in one of several temperature conditions for various time intervals, during which they were removed, from. its storage conditions, allowing the equilibrium at room temperature (about 20 ° C) and then tested for its content of hydrogen peroxide which was expressed as% by weight. The tests of the liquid compositions of the -E5 use small samples removed from a flask, sample. The . Tests of the El-E5 compositions applied to a wipe were based on the "expressed" liquid (manually squeezed) out of a roll of wipes that had been stored a. a specific temperature during a period of time required; an individual roll was used for each test, and the rolls were not retested at a later date or later test but were discarded. The hydrogen peroxide content of a test sample was evaluated by a standard quantitative laboratory titration method. The results of the. proof of this evaluation are set forth in the following Table 4. > o o (_p "-" indicates not tested As evident from the above, the wipe articles which had been pretreated with the finishing composition comprising methyl bis (tallow amidoethyl) -2-hydroxyethyl ammonium methyl sulfate (in particular, Accosoft® 501) and- applied thereafter the El or E2 compositions retain a significant proportion of the hydrogen peroxide even after 6 weeks, and particularly after 12 weeks of storage at elevated temperatures. In contrast composition E5, although it shows good retention of its original concentration of hydrogen peroxide when in its liquid form, the same composition which was applied to the wipe article exhibited a drastic loss of the content of. hydrogen peroxide even in short storage times at higher temperatures, particularly when compared to the wipe comprising the El or E2 compositions.

The percentage of the "loss" of hydrogen peroxide (reduction of hydrogen peroxide as compared to the initial levels in the wipe, or initial liquid) of the various wipes in Table 4 is quantified in the next Tables.5. . - "indicates not tested The previous results reported in the Table. 5 confirm the previously reported results of Table 4 where the wipe articles which have been treated with a quaternary ammonium compound of diamidoamine and which have been produced with the compositions El and E2 exhibit superior storage stability, than the article of wipe produced using composition E5 whose wipes are. have pretreated with a finishing composition different from a quaternary ammonium compound of. diamidoamine.

The following compositions, E6 and E7, were produced: and which were substantially similar to the composition El except that the amount of hydrogen peroxide was slightly reduced relative to that; in the following Table 6 the content of hydrogen peroxide is expressed on the base of "100% active weight", while all other constituents are as described as in Table 2.

The compositions according to E6 exhibit excellent activity, (complete inactivation ') against the Rhinovims sample when tested in accordance with an accepted protocol.

The compositions according to E.7 were applied at a respective weight ratio of an example composition: pretreated wipe (cleaning substrate) of 4: 1. The cleaning substrate used was a non-woven wipe (having a mass of 50 grams / m2) formed of spun polyethylene terephthalate fiber, the fibers of which. they have been treated with a finishing composition to coat the fibers prior to the formation of the wipe. The spin finish was an aqueous composition, particularly. Accosoft® 50 (Stepan example) that is described to contain. 3% by weight methyl-bis (tallow amidoethyl) -2-hydroxyethyl ammonium methyl sulfate, and 2% by weight of an alkoxylated oleic acid. Such wipe articles impregnated with. The E7 composition was tested accordingly, with a protocol generally in accordance with the "Standard Operating Procedure for Disinfectant Towelette Test Against Staphylococcus aureus, - Pseudomonas aueruginosa, and S.almonella enterica", SOP Number: MB-09-04 , Revision Date: 02-26-10, submitted by the US Environmental Protection Agency, Office of Pesticide Programs.
