Publication number: 20020096537Abstract: A data processing system is used to manage and track use of chemical product in a washing machine. A detergent dispenser distributes the chemical products (e.g., detergent, rinse agent, and bleach) to the washing machine. The dispenser includes a monitor that detects dispenser data based on distribution of the chemical product by the dispenser. A database is coupled to the dispenser and stores an account identifier and an alignment identifier in association with the dispenser data of the dispenser. The database further stores corporate data in associating with the dispenser data, the account identifier, and the alignment identifier. An analysis application analyzes the dispenser data in relation with the corporate data to characterize use of the chemical product in the chemical application system and provide a feedback loop. The analysis application can limit its analysis to data associated with a given account identifier or a given alignment identifier.Type: ApplicationFiled: December 19, 2001Publication date: July 25, 2002Applicant: Ecolab Inc.Inventor: James P.

Patent number: 6399556Abstract: 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.Type: GrantFiled: March 20, 2001Date of Patent: June 4, 2002Assignee: Ecolab Inc.Inventors: Kim R.
