Abstract
Abstract An improved liquid detergent composition having a markedly decreased tendency toward film formation on the liquid surface when exposed to open air, without loss in detergency and foaming power. This includes a magnesium α-olefinsulfonate, an alcohol-ethylene oxide addition product and magnesium sulfate, all in limited concentrations, the balance being an aqueous solvent and optional additives.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
A liquid detergent composition consisting essentially of: (a) water (b) from 5 to 40% by weight of a magnesium α-olefinsalfonate having from 10 to 20 carbon atoms, (c) from 1 to 8% by weight of an addition product of a primary alcohol having from 3 to 13 carbon atoms with an average of from 1 to 20 moles of ethylene oxide per mole of said primary alcohol, or an addition product of a secondary alcohol having from 9 to 18 carbon atoms with an average of from 3 to 15 moles of ethylene oxide per mole of said secondary alcohol, and (d) from 0.2 to 5% by weight of magnesium sulfate, said constituents b, c and d being in dissolved form and the weight thereof being by weight of the composition.
Claim 2
Dependent Claim
131 words
A liquid detergent composition consisting essentially of: (a) water (b) from 5 to 40% by weight of a magnesium α-olefinsalfonate having from 10 to 20 carbon atoms, (c) from 1 to 8% by weight of an addition product of a primary alcohol having from 3 to 13 carbon atoms with an average of from 1 to 20 moles of ethylene oxide per mole of said primary alcohol, or an addition product of a secondary alcohol having from 9 to 18 carbon atoms with an average of from 3 to 15 moles of ethylene oxide per mole of said secondary alcohol, and (d) from 0.2 to 5% by weight of magnesium sulfate, said constituents b, c and d being in dissolved form and the weight thereof being by weight of the composition.
Claim 3
Dependent Claim
35 words
The liquid detergent composition as claimed in claim 1 wherein said magnesium α-olefinsulfonate has an average of from 13.5 to 16.0 carbon atoms, with from 25 to 75% of the same having 14 carbon atoms.
Claim 4
Dependent Claim
30 words
The liquid detergent composition as claimed in claim 1 wherein the amount of the component (c) in said detergent composition is in the range from 2 to 6% by weight.
Claim 5
Dependent Claim
24 words
The liquid detergent composition as claimed in claim 1 further comprising ethyl alcohol in a weight ratio to said water of 1.5 or less.
