Patent number: 8076155Abstract: A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. Response data obtained by the detector is indicative of the optical absorbance of the sample mixture as a function of time. A processor analyzes the response data to determine a corresponding best fit linear relationship. Depending upon an expected concentration range, the initial absorbance and/or the slope of the best fit equation are used to calculate the concentrations of the peracid and peroxide in the use composition.Type: GrantFiled: February 12, 2009Date of Patent: December 13, 2011Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, Christopher Owen, Paul R.

Patent number: 7531365Abstract: Described is apparatus and a process for the enablement of functional product analysis of the headspace proximate one or more substrate, such as hair, fabric or skin, surfaces having affixed thereto functional product, a fragrance composition and/or malodor counteractant composition-containing microcapsules. The apparatus employs mobile microcapsule-abrading solid objects, including agitating stainless steel spheres during analyte collection in a gas-flow/trapping tube analyte collection apparatus. The reciprocating motion and the air-flow are commenced simultaneously thereby enabling the solid objects to become mobile and to effectively abrade the microcapsules affixed to the semi-solid surfaces.Type: GrantFiled: January 8, 2004Date of Patent: May 12, 2009Assignee: International Flavors & Fragrances Inc.Inventors: Danielle Lagard, George Allen Reiner, Gary William Christensen
