Patent number: 5700771Abstract: Disclosed is a detergent composition comprising a polyhydroxy fatty acid amide surfactant of the formula: ##STR1## wherein R.sup.1 is H, C.sub.1 -C.sub.4 hydrocarbyl, 2-hydroxy ethyl, 2 hyroxy propyl, or a mixture thereof, R.sup.2 is C.sub.5 -C.sub.31 hydrocarbyl, and Z is a polyhydroxy-hydrocarbyl having a linear hydrocarbyl chain with at least 3 hydroxyls connected directly to said chain, or an alkoxylated derivative thereof, and a non-borate, non-borate-forming bleaching agent such as the persulfates and especially the percarbonate bleaches. Mixtures of non-perborates with bleach activators such as tetraacetyl ethylene diamine are also used in the compositions. Also disclosed is a method for cleaning substrates, such as fabrics, fibers, textiles, hard surfaces, etc., at temperatures below about 50.degree. C., especially below about 40.degree. C.Type: GrantFiled: March 7, 1995Date of Patent: December 23, 1997Assignee: The Procter & Gamble CompanyInventors: Frederick Edward Hardy, Bruce Prentiss Murch

Patent number: 5698510Abstract: A process for making granular detergent compositions or components comprising from about 35% to about 85% by weight of a surfactant system comprising a mixture of polyhydroxy fatty acid amide and ethoxylated nonionic surfactant. The surfactant system is in the solid phase at temperatures of 25.degree. C. and below, and has a softening point from above 25.degree. C. to 100.degree. C. Additionally, the surfactant system has a viscosity profile whereby its viscosity is at least about 20,000 cps at a temperature of 10.degree. C. above the softening point, and less than about 10,000 cps at a temperature of 30.degree. C. above the softening point, all viscosities being measured at a shear rate of 25 s.sup.-1.Type: GrantFiled: March 12, 1996Date of Patent: December 16, 1997Assignee: The Procter & Gamble CompanyInventors: Carole Patricia Wilkinson, Paul Amaat Raymond France, John Christian Schmitt

Patent number: 5670473Abstract: A method for forming solid cleaning agents starts with hydrated forms of salts that generally have considerably lower melting points in their hydrated forms. The hydrated salt cleaning agents are heated to form a melted cleaning suspension. Additional ingredients can be mixed into the melted cleaning suspension. These additional ingredients can be selected from the group consisting of nonionic surfactants, anionic surfactants, alkaline builders, multivalent metal sequestering agents, active enzymes, soil suspending agents, defoamers, oxygenated solvents, fragrances, optical brighteners and colorants. An alternative method involves the formation of a mixture of powder or granular cleaning composition components. These components include at least 15 percent by weight of a moderate melting point cleaning additive. A receptacle with the cleaning components is heated to a temperature above the melting point of the moderate melting point cleaning additive.Type: GrantFiled: June 6, 1995Date of Patent: September 23, 1997Assignee: Sunburst Chemicals, Inc.Inventor: William H. Scepanski
