Attorney, Agent or Firm:

Specific alkylpolysaccharide detergent surfactants uniquely provides structure and detergency to detergent granules prepared by drying aqueous mixtures of the granules' ingredients. Such granules can contain higher amounts of water while retaining good structure.

DETAILED DESCRIPTION What is claimed is: 1.
A homogeneous granular detergent composition comprising: (1) from about 2% to about 30% of alkylpolysaccharide detergent surfactant having the formula RO(R.
sup.
1 O).
sub.
t Z.
sub.
x wherein R is an alkyl, alkylphenol, hydroxyalkyl, hydroxy alkylphenol, or mixtures thereof, and said alkyl groups contain from about 8 to about 18 carbon atoms; wherein each R.
sup.
1 contains from 2 to about 4 carbon atoms; wherein t is from 0 to about 5; wherein Z is a moiety derived from a reducing saccharide containing from 5 to 6 carbon atoms; and wherein x is from about 11/2 to about 5; (2) from 0% to about 30% of detergent cosurfactant; (3) from about 10% to about 75% of water-soluble neutral or alkaline salt; and (4) from about 5% to about 20% water.
2.
The composition of claim 1 wherein R contains from about 10 to about 14 carbon atoms, t is 0, and x is from about 11/2 to about 21/2.
3.
The composition of claim 2 containing from about 6% to about 25% of (1).
4.
The composition of claim 2 wherein said detergent cosurfactant is calcium sensitive anionic detergent cosurfactant having the formula R(SO.
sub.
3).
sub.
y (COO).
sub.
z (OSO.
sub.
3).
sub.
n M.
sub.
q wherein R has the meaning given hereinbefore; y, z and n are numbers from 0 to about 4; y+z+n is from 1 to about 3, M is a cationic moiety selected from the group consisting of sodium, potassium, ammonium, ethanolammonium, diethanolammonium, triethanolammonium, calcium, magnesium and mixtures thereof; and q is selected to complete the formula, the ratio of (2) to (1) being from about 1:1 to about 6:1.
5.
The composition of claim 4 containing from about 10% to about 20% of (2) and (2) is selected from the group consisting of alkylbenzene sulfonates in which the alkyl contains from about 6 to about 20 carbon atoms, alkyl sulfates containing from about 6 to about 30 carbon atoms, alkyl sulfonates containing from about 6 to about 30 carbon atoms, fatty acid soaps containing from about 6 to about 30 carbon atoms, and mixtures thereof
