Patent number: 4514444Abstract: Fabric cleaning/conditioning compositions of improved stability are disclosed for use through-the-wash in conjunction with machine dryers. This is accomplished by incorporating a low level of polyethylene glycol into small, discrete amine salt nodules. These nodules pass virtually unchanged through the wash and rinse; become entangled in the fabrics when spun or wrung out; and then melt, spread, and condition the fabrics when heated in a dryer.Type: GrantFiled: February 3, 1984Date of Patent: April 30, 1985Assignee: The Procter & Gamble CompanyInventors: Donald T. Ives, Michael J. Madill, Philip G. Sliva

Patent number: 4256598Abstract: Combined washing and bleaching of cotton fabrics is accomplished by use of a composition comprising surfactant and a photoactivator. The surfactant is anionic, nonionic, semi-polar, ampholytic, or zwitterionic in nature. The photoactivator is a sulfonated porphine or mono-, di- or tri-aza porphine; metal free or metallated with Zn(II), Ca(II), Cd(II), Mg(II), Sc(III), Al(III) or Sn(IV).Type: GrantFiled: January 10, 1979Date of Patent: March 17, 1981Assignee: The Procter & Gamble CompanyInventor: Nabil Y. Sakkab

Patent number: 4256597Abstract: Combined washing and bleaching of fabrics is accomplished by use of a composition comprising surfactant and a photoactivator. The surfactant is anionic, nonionic, semi-polar, ampholytic, or zwitterionic in nature. The photoactivator is a porphine or a mono-, di-, tri-, or tetra-aza porphine, solubilized with anionic, nonionic and/or cationic substituent groups, and metal free or metallated with Zn(II), Ca(II), Cd(II), Mg(II), Sc(III), Al(III) or Sn(IV).Type: GrantFiled: January 10, 1979Date of Patent: March 17, 1981Assignee: The Procter & Gamble CompanyInventor: Nabil Y. Sakkab

Patent number: 4255273Abstract: Improved fabric bleaching and stain removal are achieved by use of a composition comprising a photoactivator and a cationic substance. The photoactivator is a porphine or a mono-, di-, tri-, or tetra-aza porphine, solubilized with anionic, nonionic and/or cationic substitutent groups, and metal free or metallated with Zn(II), Ca(II), Cd(II), Mg(II), Sc(III), Al(III) or Sn(IV). The cationic substance is preferably one that, in a laundry bath, itself performs a desired function such as acting as fabric softener, electrostatic control agent, surfactant, or germicide.Type: GrantFiled: January 10, 1979Date of Patent: March 10, 1981Assignee: The Procter & Gamble CompanyInventor: Nabil Y. Sakkab
-
Patent number: 4253993Abstract: A shampoo composition in the form of flakes is prepared by processing an aqueous slurry of C.sub.12-14 alkyl sulfate, C.sub.12-14 monoethanol amide, sodium sulfate and water. The processing step can be drum-drying, or flash-drying followed by roller-milling.Type: GrantFiled: May 18, 1979Date of Patent: March 3, 1981Assignee: The Procter & Gamble CompanyInventors: James C. Ramsey, III, Philip J. Schoner

Patent number: 4240920Abstract: Combined washing and bleaching of fabrics is accomplished by use of a composition comprising a mixture of surfactant, peroxy bleach, and porphine bleach. The surfactant is anionic, nonionic, semi-polar, ampholytic, zwitterionic, or cationic in nature. The peroxy bleach is inorganic or organic. The porphine bleach is a porphine or a mono-, di-, tri-, or tetra-aza porphine, solubilized with anionic, nonionic and/or cationic substituent groups, and metal free or metallated with Zn(II), Cd(II), Mg(II), Ca(II), Al(III), Sc(III) or Sn(IV).Type: GrantFiled: February 27, 1979Date of Patent: December 23, 1980Assignee: The Procter & Gamble CompanyInventor: Manuel J. de Luque
-
Patent number: 4233164Abstract: Liquid fabric conditioning compositions having good chemical and physical stability are provided by mixtures of a quaternary ammonium salt, protonated dipolyethoxy mono-alkyl amine, a lower alcohol, and water. Addition of nonionic fabric conditioning agents is optional.Type: GrantFiled: June 5, 1979Date of Patent: November 11, 1980Assignee: The Proctor & Gamble CompanyInventor: James E. Davis
-
Patent number: 4217105Abstract: A process of bleaching cotton fabrics, especially in relation with household laundry, is provided by adsorbing on the fabric sulfonated zinc phthalocyanine photoactivator followed by rinsing and drying of the fabrics in the presence of visible light and oxygen.Type: GrantFiled: March 22, 1978Date of Patent: August 12, 1980Assignee: The Procter & Gamble CompanyInventor: John F. Goodman
-
