Abstract: Hard floor finishes and other stubborn soils can be removed using an aqueous dispersion of an alkylene glycol phenyl ether solvent combined with an ether alcohol solvent/coupler. Each component is used at a concentration that result in the creation of a visible dispersed appearance of the aqueous dilute use solutions. We have found that the alkylene glycol phenyl ether, in combination with at least one ether alcohol coupler or solvent, interacts with the aqueous medium to surprisingly provide enhanced cleaning performances. Hard to remove soils such as highly crosslinked urethanes and acrylic materials can be solubilized and removed by the alcohol solvent dispersions of the invention. We have found that the alkylene phenyl ether solvent requires a specific coupler cosolvent for activity. Such activity can be enhanced by the presence of a second coupler cosolvent and the use of a specific class of nonionic surfactant materials.

Abstract: The ability of aqueous laundry compositions to remove organic hydrophobic soils, such as oily, greasy or particulate soils, from a laundry item is substantially improved by pre-spotting or pre-treating such a soiled item with a treatment composition having a surfactant comprising a unique hydrophillic ethoxylate surfactant with less than two moles of ethylene oxide or a or blend of at least two surfactant compositions with a blended HLB value of about 7-12. The blend of surfactants with this HLB value penetrates soils and renders the soil more easily removed from the item using aqueous laundry detergent. The treatment composition can be used in a liquid or solid form and can be applied to individual laundry items in the form of a solid stick or liquid spray prior to introduction to the laundry machine. Laundry items can also be contacted in the laundry machine with the pre-spot or pre-treatment composition in the form of an aqueous presoak, preflush, prewash, or other step prior to the cleaning step. A preferred laundry machine comprises an institutional tunnel washer.
