ABSTRACT:
TECHNICAL FIELD
The present invention relates to wipes, articles of manufacture and methods for cleaning and/or sanitizing/disinfecting, foods, food contact surfaces, toys and/or infant contact surfaces, especially for the purpose of making food safe for human consumption, and/or toys and/or infant contact surfaces making safe for children, safe for use by and around children.
BACKGROUND OF THE INVENTION
Fruits and vegetables, food contact surfaces, and sometimes other food products such as meats, are desirably washed prior to ingestion in order to remove soils and other unwanted residues, such as waxes and pesticides which may be undesirably clinging to the surfaces thereof. It is also desirable to reduce microorganisms on food and food contact surfaces, thus ensuring safety.
Similarly, toys and/or infant contact surfaces, such as, high chair trays and interiors of baby bottles, are also desirably washed prior to use by the child in order to remove soils and other unwanted residues which may be undesirably clinging to the surfaces thereof. This is especially true of toys that are left outside exposed to the elements, or toys dropped by a child while away from the home environment. Another problem is that of contact of a toy with multiple children either from infants visiting friends or friends coming to visit. A similar situation is faced by day care facilities, creches, play grounds, “theme” restaurants and the like where large numbers of children interact with the same toys and surfaces. The possible variety, number and volume of assorted bugs and other microbial organisms any given infant is exposed to is large enough for both parental and professional concern about the sanitary conditions of these facilities. The present solution typically involves the use of harsh chemicals, such as chlorine bleaches. While these work, they raise health and safety issues not only for the individual cleaning and sanitizing, but also for any infant who later contacts the surface. Furthermore, these are not easily transportable for use by a caregiver when they would need it the most, such as, when out shopping or traveling away from home.
Consequently, there remains a need for cleaning and sanitizing food, food contact surfaces, toys, and/or infant contact surfaces which are safe for the user as well as the infant, easy to use, convenient, readily transportable, while providing at least comparable, if not superior, cleaning and/or sanitizing to existing products.

SUMMARY OF THE INVENTION
In accordance with a first aspect of the present invention, a premoistened wipe is provided. The wipe comprises:
(a) a substrate; and
(b) a composition comprising:
(i) optionally, a toxicologically-acceptable anionic surfactant;
(ii) optionally, a toxicologically-acceptable chelant;
(iii) optionally, a toxicologically-acceptable nonionic surfactant;
(iv) optionally, a toxicologically-acceptable buffer;
(v) optionally, a toxicologically-acceptable preservative;
(vi) optionally, a toxicologically-acceptable suds suppressor;
(vii) optionally, a toxicologically-acceptable perfume; and
(viii) the balance comprising an aqueous carrier, the aqueous carrier comprising water and optionally, a low molecular weight, toxicologically-acceptable organic solvent;
wherein the composition contains at least one of (i) to (vii); is loaded onto the substrate at a loading factor of at least about 0.5 grams of composition per gram of dry substrate; and the substrate is releasably carrying the composition.
In accordance with second aspect of the present invention, an article of commerce is provided. The article of commerce comprises:
(1) container, said container housing;
(2) one or more premoistened wipes comprising:
(a) substrate; and
(b) cleaning composition comprising;
(i) optionally, a toxicologically-acceptable anionic surfactant;
(ii) optionally, a toxicologically-acceptable chelant;
(iii) optionally, a toxicologically-acceptable nonionic surfactant;
(iv) optionally, a toxicologically-acceptable buffer;
(v) optionally, a toxicologically-acceptable preservative;
(vi) optionally, a toxicologically-acceptable suds suppressor;
(vii) optionally, a toxicologically-acceptable perfume; and
(viii) the balance comprising an aqueous carrier, the aqueous carrier comprising water and optionally, a low molecular weight, toxicologically-acceptable organic solvent;
wherein the composition contains at least one of (i) to (vii); is loaded onto the substrate at a loading factor of at least about 0.5 grams of composition per gram of dry substrate; and the substrate is releasably carrying the composition; and
(3) a set of instructions comprising an instruction to wipe a surface with the premoistened wipe, wherein the surface is selected from the group consisting of food, toys, food contact surfaces and infant contact surfaces.
In accordance with a third aspect of the present invention, a method of promoting the sale of items is provided. The method comprises:
(I) contacting the items with a premoistened wipe comprising:
(a) a substrate; and
(b) a composition comprising:
(i) optionally, a toxicologically-acceptable anionic surfactant;
(ii) optionally, a toxicologically-acceptable chelant;
(iii) optionally, a toxicologically-acceptable nonionic surfactant;
(iv) optionally, a toxicologically-acceptable buffer;
(v) optionally, a toxicologically-acceptable preservative;
(vi) optionally, a toxicologically-acceptable suds suppressor;
(vii) optionally, a toxicologically-acceptable perfume; and
(viii) the balance comprising an aqueous carrier, the aqueous carrier comprising water and optionally, a low molecular weight, toxicologically-acceptable organic solvent;
wherein the composition contains at least one of (i) to (vii); is loaded onto the substrate at a loading factor of at least about 0.5 grams of composition per gram of dry substrate; and the substrate is releasably carrying the composition; and
(II) providing informational indicia in association with the items to communicate to a consumer of the items that the items have been treated with the premoistened wipe.
Methods of using the premoistened wipes to clean the surface of an item, as defined hereinafter, are also an embodiment within the scope of the present invention.
In all of the above lists of components, if an ingredient can be classified in more than one place, it will be classified in the first place it can appear. In one embodiment of the present invention all ingredients of the composition are food grade, since they may be ingested.
All patents, articles, documents, and other materials cited herein are hereby incorporated by reference, unless otherwise indicated.
All percentages, ratios and proportions are by weight, and all temperatures are in degrees Celsius (° C.), unless otherwise specified. All measurements are in SI units unless otherwise specified.
DETAILED DESCRIPTION OF THE INVENTION
Definitions
The term “toy” is meant to literally be any non-living child's plaything. That is, the term “toy” includes within its meaning, balls, dolls, blocks, action figures, rattles and the like. Also included within the meaning of the term “toy”, are items that are not specifically designed for use as a toy. This would include items that are viewed as a plaything by the child or items given to the child by a caregiver or parent for the child's amusement and/or distraction. For example, cooking utensils, such as wooden spoons, ladles, bowls, cups, storage containers, such as used baby wipe container, TUPPERWARE ® and the like and are included in this definition.
The phrase “second hand toy” means any toy, as defined above, which has been previously sold and is about to be resold by the original or subsequent purchaser. Alternatively, a third party could resell or be about to resell the t
