Patent number: 5922664Abstract: Aqueous detergent concentrates containing a mixture of two or more surfactants having a differing resistance to electrolytic salting out in the form of micellar solutions and having pourable viscosities are converted into lamellar solutions upon dilution with water where the dispersion contains a viscosity promoting electrolyte present at a narrow range of concentration. Transformation from the micellar phase to the lamellar phase produces an increase in viscosity such that the diluted concentrate has a viscosity equal to or higher than the viscosity of the original concentrate.Type: GrantFiled: May 6, 1997Date of Patent: July 13, 1999Assignee: Colgate-Palmolive Co.Inventors: Hoai-Chau Cao, Patricia Pagnoul

Patent number: 5912406Abstract: A method of cleaning soiled fabrics, particularly fabrics that are hydrophobic, with an aqueous fabric cleaning composition having a non-ionic surfactant. The method involves alternately adjusting the wash temperature to above and below the cloud point of the non-ionic surfactant to remove oily soils from the fabrics.Type: GrantFiled: May 20, 1998Date of Patent: June 15, 1999Inventor: Robert H. Black

Patent number: 5885952Abstract: A detergent base which is obtainable from the reaction of an ethylenically unsaturated sulfonic acid or carboxylic acid or anhydride thereof with a nonionic surfactant of the formulaR.sub.1 --O-(alkylene-O).sub.n.sbsb.1 --R.sub.2 (1)in whichR.sub.1 is C.sub.8 -C.sub.22 alkyl or C.sub.8 -C.sub.18 alkenyl;R.sub.2 is hydrogen, C.sub.1 -C.sub.4 alkyl, a cycloaliphatic radical having at least 6 C atoms or benzyl; andn.sub.1 is a number from 1 to 60;and if appropriate with sugar derivatives.The detergent base has a good calcium-dispersing power, is very stable to electrolytes and heat and has an excellent washing action and anti-redeposition properties. It is therefore suitable for the preparation of powder and liquid detergents.Type: GrantFiled: May 15, 1996Date of Patent: March 23, 1999Assignee: Ciba Specialty Chemicals CorporationInventors: Rolf Kuratli, Claude Eckhardt, Frank Bachmann, Werner Schreiber
