New alkyl mono and polyglycoside phosphate esters and anionic derivatives thereof are described which compounds have the general formula

Alkyl mono and polyglycoside phosphate esters

Glycoside products are successfully prepared directly from aqueous saccharide solutions or syrups, and with acceptably low levels of undesired homopolymerized saccharide by-products, by dissolving same in the desired alcohol reactant or in an alcohol reactant plus glycoside product mixture and contacting the resulting homogeneous aqueous saccharide solution and alcohol-containing reaction medium with an acid catalyst in a fashion such that no separate or distinct, substantially alcohol reactant-free aqueous saccharide solution-containing phase is permitted to come into contact with said acid catalyst material under conditions conductive to homopolymerization of said saccharide reactant.

Glycoside preparation directly from aqueous saccharide solutions or

The catalytic hydrogenation of a glycoside composition to reduce the color of the composition is disclosed.

Decolorization of glycosides

Medium and long-chain alkyl glycosides are prepared by reacting a saccharide and a monohydric alcohol in the presence of at least 1 mole N-methyl-2-pyrrolidone per mole saccharide unit. The saccharide is selected from the group consisting of unsubstituted saccharides, short-chain alkyl glycosides, and mixtures thereof. The monohydric alcohol is selected from the group consisting of medium-chain alcohols, long-chain alcohols, and mixtures thereof. The reaction is conducted at a temperature of about 80.degree. to 140.degree. C.

Preparation of alkyl glycosides

A homogeneous and single-phase liquid laundry detergent contains alkyl glycoside nonionic surfactant and a detergent builder having a water solubility at 25.degree. C. of less than about 55 weight percent.

Built liquid laundry detergent containing alkyl glycoside surfactant

A soiled hard surface is cleaned by applying thereto and subsequently removing therefrom a cleaning composition comprising: (a) about 0.1 to 50 weight percent alkali metal hydroxide or ammonium hydroxide; (b) about 0.1 to 40 weight percent alkyl glycoside; and (c) about 10 to 95 weight percent water.

Alkaline hard-surface cleaners containing alkyl glycosides

Glycoside products are successfully prepared directly from aqueous saccharide solutions or syrups, and with acceptably low levels of undesired higher polysaccharide by-products, by dissolving same in the desired alcohol reactant and contacting the resulting homogeneous aqueous saccharide+alcohol solution with an acid catalyst material in a fashion such that substantially no separate or distinct, predominantly aqueous saccharide solution phase is permitted to come into contact with said acid catalyst material under conditions conducive to homopolymerization of said saccharide reactant.

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.

Carpet shampoo or upholstery cleaning composition

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.

Liquid hand-soap or bubble bath composition

The invention describes branched glycosides which are substantially liquid materials at high solids concentration.

Branched chain glycosides

Desirable color of glycosides are obtained through bleaching and stabilization with a source of sulfur dioxide.

Color stabilization of glycosides

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.
