Patent number: 6232280Abstract: A cleaning composition includes a detectable substance which is relatively stable in the cleaning composition, for indicating whether the cleaning composition has been thoroughly removed from a vessel following a cleaning process. For pharmaceutical applications, the detectable substance is preferably a low-foaming surfactant that is detectable by high performance liquid chromatography at concentrations of around 10 ppm, or less. The surfactant is thus detectable in the same analytical procedure as are traces of pharmaceutical residues which have not been removed from the vessel. The analytical procedure is used to develop a cleaning protocol for future cleaning processes by determining the number of rinses needed for reducing the surfactant, and hence the cleaning product, and also the pharmaceutical residues, in the rinse water to predetermined acceptable levels.Type: GrantFiled: May 12, 1999Date of Patent: May 15, 2001Assignee: Steris CorporationInventors: Sayed Sadiq Shah, Herb J. Kaiser, Shahin Keller

Patent number: 6228824Abstract: A pink colored automatic dishwasher detergent composition is formulated as a gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, red color stability and improved cleaning performance. Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener.Type: GrantFiled: September 25, 2000Date of Patent: May 8, 2001Assignee: Colgate-Palmolive CompanyInventor: Philip Gorlin

Patent number: 6228179Abstract: A surface treatment composition containing a complexing agent as a metal deposition preventive in a liquid medium, in which the complexing agent is an ethylenediaminephenol derivative of the following general formula (1) or its salt: wherein X1 and X2 are hydroxyl groups; Y1 to Y8 are respectively independently a hydrogen atom, a hydroxyl group, a halogen atom, a carboxyl group, a phosphonic acid group, a sulfonic acid group, a carbonyl group, a nitro group, a nitroso group, an amino group, an imino group, a nitrilo group, a nitrile group, a thiocyanate group, a hydroxyamino group, a hydroxyimino group, or an alkyl or alkoxy group which may have a substituent, provided that at least one of Y1 to Y8 is not a hydrogen atom; Z1 to Z4 are respectively independently a hydrogen atom, a carboxyl group or a sulfonic acid group; and R1 to R4 are respectively independently a hydrogen atom or an alkyl group which may have a substituent.Type: GrantFiled: March 10, 2000Date of Patent: May 8, 2001Assignee: Mitsubishi Chemical CorporationInventor: Hitoshi Morinaga

Patent number: 6191094Abstract: An alkaline aqueous cleaning composition for cleaning a substrate contaminated with industrial-type soil contaminants contains (i) an aqueous portion and (ii) an active-ingredient portion composed of (A) an alkalinity-providing agent and (B) a surfactant mixture containing (a) an active concentration of an ethoxylated C12-14 alkanol surfactant having an HLB value at 25° C. of from 8 to 12 and (b) an active concentration of at least one aminocarboxylic acid surfactant of the general formula R—N(H)—R′, wherein R is a straight or branched chain aliphatic organic group having from 10 to 20 carbon atoms, and R′ is a straight or branched chain carboxylic acid having from 1 to 7 carbon atoms. At an active-concentration ratio of surfactant (a) to surfactant (b) of about 2.5:1, the surfactants have a synergistic effect on the cleaning composition's ability to remove certain types of industrial-soil contaminants.Type: GrantFiled: November 5, 1998Date of Patent: February 20, 2001Assignee: Church & Dwight Co., Inc.Inventors: Francis R.
