Abstract
Description
- The present invention relates to a nonwoven fabric which has been impregnated with a liquid cleaning composition that provides a lasting antibacterial protection of hard surfaces.

- U.S. Patent Nos. 5,863,663; 5,952,043; 6,063,746 and 6,121,165 teaches cleaning compositions which are out in water emulsions.
- A cleaning wipe for cleaning and lasting antibacterial protection of hard surfaces such as walls, toilet bowl, bath tub, door handle, tables, counter tops and floors comprises a nonwoven fabric containing at least polyester fibers and viscose fibers, wherein the nonwoven fabric is impregnated with a liquid cleaning composition which comprises an anionic surfactant and a polycationic antibacterial agent, a nonionic surfactant or an emulsifier, optionally, a perfume, optionally, a proton donating agent, optionally, cosurfactants and solvents and water, wherein the liquid cleaning composition is not an emulsion and does not contain proteins, metallic salts, enzymes, amides, sodium hypochlorite, dimethicone, N-methyl-2-pyrrolidone, monoalkyl phosphate or silicon based sulfosuccinate.

The nonionic synthetic organic detergents generally are the condensation products of an organic aliphatic or alkyl aromatic hydrophobic compound and hydrophilic ethylene oxide groups. Practically any hydrophobic compound having a carboxy, hydroxy, amido, or amino group with a free hydrogen attached to the nitrogen can be condensed with ethylene oxide or with the polyhydration product thereof, polyethylene glycol, to form a water-sotuble nonionic detergent. Further, the length of the polyethenoxy chain can be adjusted to achieve the desired balance between the hydrophobic and hydrophilic elements.
- The nonionic surfactant class includes the condensation products of a higher alcohol (e.g., an alkanol containing 8 to 18 carbon atoms in a straight or branched chain configuration) condensed with 5 to 30 moles of ethylene oxide, for example, lauryl or myristyl alcohol condensed with 16 moles of ethylene oxide (EO), tridecanol condensed with 6 to moles of EO, myristyl alcohol condensed with 10 moles of EO per mole of myristyl alcohol, the condensation product of EO with a cut of coconut fatty alcohol containing a mixture of fatty alcohols with alkyl chains varying from 10 to 14 carbon atoms in length and wherein the condensate contains either 6 moles of EO per mole of total alcohol or 9 moles of EO per mole of alcohol and tallow alcohol ethoxylates containing 6 EO to 11 EO per mole of alcohol.
- A preferred group of the foregoing nonionic surfactants are the Neodol ethoxylates (Shell Co.), which are higher aliphatic, primary alcohol containing 9-15 carbon atoms, such as C9-C11 alkanol condensed with 2.5 to 10 moles of ethylene oxide (NEODOL 91-2.5 OR-5 OR-6 OR -8), C12-13 alkanol condensed with 6.5 moles ethylene oxide (Neodol 23-6.5), C12-15 alkanol condensed with 12 moles ethylene oxide (Neodol 25-12), C14-15 alkanol condensed with 13 moles ethylene oxide (Neodol 45-13), and the like.
