  • Patent number: 5266690
    Abstract: A process for preparing high detergency or surfactant alkyl polyglycoside compositions and a purified alkyl monoglycoside and to compositions employing the polyglycosides for various end use applications. The process involves removal of a substantial portion of the monoglycoside present in a reaction product mixture containing alkyl polyglycosides resulting from the reaction of an alcohol and saccharide at elevated temperatures in the presence of an acid catalyst. Separation of the monoglycoside from the reaction product mixture may be carried out by molecular distillation.

  • Patent number: 5118439
    Abstract: The invention is a process for preparing a carbonate containing detergent slurry with reduced viscosity by incorporating in the detergent slurry from 0.5 to 10% of an alkylpolyglycoside and 0.5 to 10% of an alkali metal chloride, the percentage being by weight of the non-aqueous portion of the slurry.

  • Patent number: 4834903
    Abstract: Remarkably good surfactancy characteristics are exhibited by alkylene oxide (e.g., ethylene oxide, propylene oxide, etc.) adducts of relatively low degree of polymerication, (D.P.), long chain glycoside compositions of the sort which are predominantly composed of long chain monoglycoside species and in which the types and relative proportions of any long chain polyglycoside species contained therein are such that the average degree of polymerization of such long chain glycoside constituents is less than 2.7.The subject low D.P. long chain polyglycoside alkylene oxide adducts exhibit surfactancy and/or detergency characteristics at least about as good as, and in some respects substantially better than, the corresponding alkylene oxide adducts of higher D.P. long chain glycoside materials.

  • Patent number: 4678595
    Abstract: Aqueous liquid carpet and upholstery shampoo compositions are provided which comprise a glycoside surfactant, a normally solid, water soluble or water dispersible polymer component and water. In a particularly preferred embodiment, the surfactant ingredient employed consists essentially of one or more glycoside surfactants and utilizes a polymer-containing shampoo modifier system of the type disclosed in U.S. Pat. No. 4,203,859.The indicated compositions are utilized in the cleaning of soiled carpet or upholstery by applying said composition to the soiled carpeting or upholstery; permitting same to dry and harden thereon and thereafter removing at least a portion of the resulting soil-containing polymer residue by vacuuming.

  • Patent number: 4675127
    Abstract: Particulate detergent compositions are prepared by (a) forming an aqueous crutcher slurry having a total solids content of from about 40 to about 80 weight percent on a total weight basis and comprising a surfactant ingredient, al least about 0.1 weight percent (surfactant weight basis) of which is a glycoside surfactant; a builder ingredient; water; and, optionally, a filler ingredient and (b) thereafter drying said aqueous crutcher slurry. In an especially preferred embodiment, the glycoside surfactant is employed as an additive in a relatively small but effective amount (i.e., corresponding to less than about 2 weight percent on a dry solids weight basis) to provide reduced viscosity and/or enhanced homogeneity to the crutcher slurry compositions of interest.

  • Patent number: 4668422
    Abstract: Liquid hand-soap or bubble bath compositions are provided which comprise a glycoside surfactant, a nonionic foam booster and water and which have a viscosity of at least about 1,000 centipoise. Such compositions have a pleasing texture or consistency, are mild and fast rinsing and do not necessarily require the use of conventional moisturizing agents or additives. Preferred compositions further comprise an anionic or amphoteric surfactant material and especially preferred compositions contain an amphoteric surfactant and are substantially free of anionic surfactant components.

  • Patent number: 4488981
    Abstract: Lower alkyl glycosides are added to aqueous liquid detergents to reduce their viscosity and to prevent phase separation. The glycosides are represented by the formula R--O--(G).sub.n where "R" is a lower alkyl group having 2 to 6 carbon atoms, "O" is an oxygen atom, "G" is a saccharide unit, and "n" is a number from 1 to 10. The glycosides comprise about 1 to 10 weight percent of the detergents.

  • Patent number: 4170678
    Abstract: A multiple use article for conditioning of fabrics in a laundry dryer comprising an initially multiple-layer flexible substrate carrying a conditioning agent transferable to fabrics when tumbled therewith in a clothes dryer. The dryer operator modifies the shape of the multiple-layer flexible substrate between successive uses to expose additional fabric-conditioning agent for transfer to additional fabrics subsequently loaded in the clothes dryer.
