Abstract

Premoistened wipes containing a substrate and a cleaning composition using toxicologically-acceptable ingredients for treating food such as produce, e.g., fruits and vegetables, edible animal proteins, toys baby high chairs and the like, are provided.

Claims

1. A premoistened wipe comprising:

(a) a nonwoven substrate, said substrate being selected from the group consisting of carded nonwovens, air-laid nonwovens, melt blown nonwovens and spunbonded nonwovens; 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, said aqueous carrier comprising water and optionally, a low molecular weight, toxicologically-acceptable organic solvent;

wherein said composition contains at least a surfactant selected from the group consisting of (i), (iii) and combinations thereof;

said composition has a pH of from about 9.5 to about 13.0 and is loaded onto said substrate at a loading factor of at least about 0.5 grams of composition per gram of dry substrate so that said substrate is wet by said composition;

wherein said substrate is releasably carries the composition; and

said composition comprises only GRAS and/or food grade ingredients.

2. The premoistened wipe of claim 1, wherein said anionic surfactant is selected from the group consisting of alkali or alkaline earth salts of C_6-16 alkyl sulfate, alkali or alkaline earth salts of C_6-16 alkyl sulfonate, C_8-18 fatty acid and salts thereof and mixtures thereof.

3. The premoistened wipe of claim 2, wherein said anionic surfactant is selected from the group consisting of sodium or potassium salts of C_6-16 alkyl sulfates, C_8-18 fatty acid or salts thereof, sodium or potassium salts of C_6-16 alkyl sulfonates, and mixtures thereof.

4. The premoistened wipe of claim 1, wherein said composition contains at least two of (i) to (vii).

5. The premoistened wipe of claim 1, wherein said buffer is selected from the group consisting of water soluble borates, hydroxides, ortho-phosphates, carbonates, bicarbonates, citrates and mixtures thereof.

6. The premoistened wipe of claim 1, wherein said chelant is selected from the group consisting of sodium polyphosphate, potassium polyphosphate, organic polycarboxylate and mixtures thereof.

7. The premoistened wipe of claim 6, wherein said chelant is selected from the group consisting of sodium polyphosphate, potassium polyphosphate, ethylenediaminetetraacetate, citrate, and mixtures thereof.

8. The premoistened wipe of claim 1, wherein said organic solvent is selected from the group consisting of C₂-C₆ alcohols, C₂-C₆ diols, C₂-C₆ triols, and mixtures thereof.

9. The premoistened wipe of claim 8, wherein said organic solvent is selected from the group consisting of ethanol, glycerol, and mixtures thereof.

10. The premoistened wipe of claim 1, wherein said composition comprises:

(i) from about 0.01% to about 5.0% by weight of composition of said anionic surfactant;

(ii) from about 0.0005% to about 3.0% by weight of composition of said chelant;

(v) from about 0.0005% to about 10.0% by weight of composition of said buffer;

(vii) from about 0.01% to about 1.0% by weight of composition of perfume; and

(viii) the balance comprising said aqueous carrier, said aqueous carrier comprising water and said low molecular weight, toxicologically-acceptable organic solvent.

11. An article of commerce according to claim 1, wherein said article is further provided with informational indicia, wherein said informational indicia is selected from the group consisting of an advertisement, logo, brochure, sticker, sign, and combinations thereof.

12. An article according to claim 11, wherein said informational indicia are a sign comprising a brand name of said premoistened wipes.

13. A method of treating a toy comprising contacting said toy with the premoistened wipe of claim 1.
