  • Patent number: 6309471
    Abstract: The present invention relates to an improved method of removing iodine stains comprising contacting a surface having an iodine stain with a liquid cleaning composition for a sufficient time to decolorize the stain said cleaning composition comprising about 1% to about 100% by weight of at least one compound selected from the group consisting of salicylic acid, salicylic acid derivatives and mixtures thereof, and at least one solvent. The liquid cleaning composition has an adjusted pH of about 1-14.

  • Publication number: 20010014658
    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.

  • Patent number: 6180592
    Abstract: A hydrophobic and particulate soil removal composition is provided. The composition can be used for removing organic hydrophobic soils, such as oily or greasy soils, from a laundry item and/or from a hard surface such as an engine part and/or from skin. The 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. The treatment composition can be used as a recirculating liquid stream or bath for the cleaning of hard surfaces. The composition includes an ethoxylate component and a fatty acid ester component.
