Abstract
Abstract A stable, non-gelling, low-foaming unbuilt aqueous liquid detergent is obtained by inclusion, in an aqueous medium, of 25-45% of a ternary nonionic detergent mixture, wherein the nonionics are high-, medium- and low-ethoxylated fatty alcohols with specific alkyl chain lengths.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
84 words
An aqueous liquid unbuilt detergent composition containing 25-45% by weight of a nonionic detergent surfactant mixture, said mixture consisting essentially of: (a) 50-80% by weight of a primary C 16 -C 19 saturated fatty alcohol, condensed with 15-19 moles of ethylene oxide; (b) 5-25% by weight of a primary C 8 -C 12 saturated fatty alcohol, condensed with 6-10 moles of ethylene oxide; (c) 5-25% by weight of a primary C 10 -C 14 saturated fatty alcohol, condensed with 1-4 moles of ethylene oxide.
Claim 2
Dependent Claim
84 words
An aqueous liquid unbuilt detergent composition containing 25-45% by weight of a nonionic detergent surfactant mixture, said mixture consisting essentially of: (a) 50-80% by weight of a primary C 16 -C 19 saturated fatty alcohol, condensed with 15-19 moles of ethylene oxide; (b) 5-25% by weight of a primary C 8 -C 12 saturated fatty alcohol, condensed with 6-10 moles of ethylene oxide; (c) 5-25% by weight of a primary C 10 -C 14 saturated fatty alcohol, condensed with 1-4 moles of ethylene oxide.
Claim 3
Dependent Claim
55 words
