Built liquid laundry detergent containing alkyl glycoside surfactant

Claim 1

A liquid laundry detergent composition which is essentially free of hydrotropes and is homogeneous and single-phase at 25° C. and which comprises: (a) about 5 to 50 weight percent surfactant, at least 50 weight percent of which is an alkyl glycoside surfactant having the formula: RO--(R'O).sub.x --Z.sub.y where R is a monovalent alkyl radical containing about 8 to 25 carbon atoms, O is an oxygen atom, R' if a divalent alkyl radical containing 2 to 4 carbon atoms, x is a number having an average value of 0 to about 12, Z is a reducing saccharide moiety containing 5 or 6 carbon atoms, and y is a number having an average value of about 1 to 10; (b) a detergent builder consisting essentially of builders selected from the group consisting of sodium tripolyphosphate, alkali metal carbonates, alkali metal citrates, and alkali metal metasilicates; said detergent builder being present in a quantity at least equal to the greater of: (i) 3 weight percent; or (ii) 2 times the solubility limit of such builder in a corresponding benchmark composition wherein the alkyl glycoside surfactant has been replaced by an equal weight of an ethoxylated alcohol nonionic surfactant having an average of 7 ethylene oxide units per molecule and consisting of a blend of the following alcohols: about 28 weight percent dodecyl alcohol; about 36 weight percent tridecyl alcohol; about 19 weight percent tetradecyl alcohol; and about 17 weight percent pentadecyl alcohol; and (c) about 45 to 90 weight percent water.
