Abstract
Abstract Liquid detergent compositions comprise 25-60% by weight of solids suspended in a liquid phase comprising at least 20% by weight of a condensation product of ethylene oxide with a mono- or di- or tri- hydroxy alkane having 1 to 4 carbon atoms having an average molecular weight in the range 150to 600. The solids comprise a builder and optionally a bleach, and the liquid phase preferably comprises a surfactant.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
73 words
A liquid detergent composition which comprises 25 to 60% by weight of the composition of solids suspended in a non-aqueous liquid phase, the solids comprising a builder, in which the liquid phase comprises at least 20% by weight of a condensation product of ethylene oxide with a mono- or di- or tri- hydroxy alkane having 1 to 4 carbon atoms which condensation product has a molecular weight in the range 150 to 600.
Claim 2
Dependent Claim
73 words
A liquid detergent composition which comprises 25 to 60% by weight of the composition of solids suspended in a non-aqueous liquid phase, the solids comprising a builder, in which the liquid phase comprises at least 20% by weight of a condensation product of ethylene oxide with a mono- or di- or tri- hydroxy alkane having 1 to 4 carbon atoms which condensation product has a molecular weight in the range 150 to 600.
Claim 3
Dependent Claim
52 words
A liquid detergent composition which comprises 25 to 60% by weight of the composition of solids suspended in a non-aqueous liquid phase the solids comprising a builder, in which the liquid phase comprises at least 20% by weight of a polyethylene glycol having a molecular weight in the range 150 to 600.
Claim 4
Dependent Claim
52 words
A liquid detergent composition which comprises 25 to 60% by weight of the composition of solids suspended in a non-aqueous liquid phase the solids comprising a builder, in which the liquid phase comprises at least 20% by weight of a polyethylene glycol having a molecular weight in the range 150 to 600.
Claim 5
Dependent Claim
32 words
A composition according to claim 2 in which the liquid phase comprises 50 to 85% by weight of the polyethylene glycol and 5 to 50% by weight of one or more surfactants.
