Abstract:

Disclosed are detergent compositions and methods which utilize certain modified cellulose ethers as fabric treatment agents that can impart fabric appearance and integrity benefits to fabrics and textiles laundered in washing solutions which contain such agents. Such modified cellulose ether fabric treatment agents are those having selected types and amounts of anhydroglucose ring substituents in order to render them nonionic, cationic or anionic in nature.

Assignee:

The Procter & Gamble Company - Cincinnati OH

International Classification:

C11D 754
C01B 15037

US Classification:

252100

Abstract:

The present invention provides an aqueous liquid bleach composition which remains stable over an extended period of time. The liquid bleach is easily pourable since it has a relatively low viscosity. The liquid bleach generally comprises (a) from about 1% to about 25% by weight of a water-soluble bleach activator; (b) from about 0. 1% to about 10% by weight of hydrogen peroxide; (c) from about 1% to about 20% by weight of a phase stabilizer; (d) from about 0. 001% to about 2% by weight of a chelating agent; and (e) the balance water. The liquid bleach composition is isotropic, translucent and has a viscosity of less than about 500 cps.

International Classification:

C11D 104
C11D 172
C11D 339

US Classification:

510413

Abstract:

Disclosed are nonaqueous, bleach-containing liquid laundry detergent compositions which are in the form of a suspension of particulate material, including peroxygen bleaching agent and an alkyl sulfate anionic surfactant, dispersed in a liquid phase containing an alcohol ethoxylate nonionic surfactant and a nonaqueous, low-polarity organic solvent. Such compositions provide especially desirable cleaning and bleaching of fabrics laundered therewith and also exhibit especially desirable chemical and phase stability.

US Classification:

252 94

Abstract:

This is a bleach granule comprising the nonylamide of peroxyadipic acid with a average particle size of about 0. 1 to 260 microns, bleach-stable surfactant, and a hydratable, NAPAA-compatible material, e. g. sodium sulfate. The bleach granules are stable and are effective bleaching agents.
