An alkaline-stable cleaning solution is mixed with an aqueous solution of alkali metal organosiliconates and applied to porous inorganic surfaces as a one-step cleaning and water repellent treatment. The mixture has been found to be stable and compatible. The one-step cleaning and water repellent treatment functions to simultaneously clean and protect porous inorganic surfaces and, thus, reduces the cost and time necessary to clean and protect such a surface.Type: GrantFiled: August 9, 1995Date of Patent: July 14, 1998Assignee: The Sherwin-Williams CompanyInventors: Victoria D. Scarborough, Leonard R. Clark

Patent number: 5747435Abstract: Composition useful as 2-in-1 cleansing products are disclosed that are extremely mild to skin and hair, which use neutralized, essentially chargeless, ionic complexes of fatty amines and fatty acids to deliver various levels of conditioning; neutralized, essentially chargeless, ionic complexes of a detersive surfactant comprising a water soluble cationic surfactant and/or polymer complexed with one or more anionic surfactants; or an amphoteric surfactant complexed with one or more anionic surfactants; or a water soluble cationic surfactant and/or polymer complexed with one or more amphoteric surfactants; or a water soluble cationic surfactant and/or polymer complexed with one or more anionic surfactants and an amphoteric surfactant; detersive surfactant-soluble but water-insoluble silicones or derivatives thereof; and water. These products exhibit true 2-in- conditioning properties, and are lower in cost than current 2 in 1 products. Clear or opacified products can be formulated.Type: GrantFiled: July 17, 1996Date of Patent: May 5, 1998Assignee: Colgate-Palmolive CompanyInventor: Amrit M. Patel

Patent number: 5744441Abstract: The present invention is directed to a process for forming a hydrotrope which effectively reduces the likelihood of phase separation in a liquid cleaning composition and simultaneously enhancing its cleaning properties by combining an alkyl polyglycoside having the formula IR.sub.7 O(Z).sub.a (I)wherein R.sub.7 is a monovalent organic radical having from about 6 to about 30 carbon atoms; Z is saccharide residue having 5 or 6 carbon atoms; a is a number having a value from 1 to about 6 and an amphoteric surfactant, in a percent actives ratio of about 1:1.The amphoteric surfactants to be used are preferably selected from the group consisting of N-alkyl beta-alanines, amino betaines, amido betaines, imidazoline betaines, amino oxides, as well as mixtures thereof.Type: GrantFiled: August 16, 1996Date of Patent: April 28, 1998Assignee: Henkel CorporationInventors: Allen D. Urfer, Michael Counts

Patent number: 5744440Abstract: Cleaning compositions are presented which surprising exhibit increased cleaning performance as the amount of solubilizing coupler is increased beyond that necessary to fully solubilize a very slightly water-soluble organic solvent component. Methods of use of the compositions to remove hydrophobic soils and soap scum are also described.Type: GrantFiled: February 6, 1996Date of Patent: April 28, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventor: Augustine Liu

Patent number: 5739096Abstract: Disclosed herein are bleaching systems that contain a peroxide and an activator. The activator is a cyanopyridine N-oxide, preferably 2, 3, or 4-cyanopyridine N-oxide. The peroxide is preferably hydrogen peroxide. When such bleaching systems are utilized in an aqueous alkaline environment, they provide bleaching performance on a variety of stains on both hard and soft surfaces.Type: GrantFiled: May 6, 1996Date of Patent: April 14, 1998Assignee: S. C. Johnson & Son, Inc.Inventor: Wayne M. Rees
