Detergent composition
A liquid hard surface detergent composition comprising a liquid mixed alkoxylate fatty alcohol non-ionic surfactant comprising a greater number of the lower higher alkoxylate group than the higher alkoxylate group in the molecule and a builder. The compositions provide good shine/anti-spotting characteristics on hard surfaces and are especially suitable for use as automatic dishwashing compositions.

a liquid mixed alkoxylate fatty alcohol non-ionic surfactant comprising at least one lower alkoxylate group and at least one higher alkoxylate group, wherein there is a greater number of moles of the lower alkoxylate group than of the higher alkoxylate group in the molecule, wherein the liquid mixed alkoxylate fatty alcohol non-ionic surfactant has the formula:
R1-[EO] n -[PO] m -[BO] p -Bu q
wherein:
R1 is an alkyl group of between C8 and C20;
EO is ethylene oxide;
PO is propylene oxide;
BO is butylene oxide;
Bu is butylene;
n is an integer from 6 to 10;
