Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
17 words
a water-soluble substance selected from the group consisting of fatty acid soaps, synthetic detergents and mixtures thereof,
Claim 2
Dependent Claim
47 words
The composition of claim 1, wherein said water-soluble substance is present in a concentration of from about 5 to 30 percent by weight of said solution, and wherein said liquid fraction of lanolin is present in a concentration of from approximately 1 to 3 percent by weight.
Claim 3
Dependent Claim
17 words
a water-soluble substance selected from the group consisting of fatty acid soaps, synthetic detergent and mixtures thereof,
Claim 4
Dependent Claim
5 words
a liquid fraction of lanolin
Claim 5
Dependent Claim
47 words
The composition of claim 1, wherein said water-soluble substance is present in a concentration of from about 8 to 24 percent by weight of said solution, and wherein said liquid fraction of lanolin is present in a concentration of from approximately 1 to 3 percent by weight.
Claim 6
Dependent Claim
5 words
a liquid fraction of lanolin,
Claim 7
Dependent Claim
20 words
a non-ionic surfactant consisting essentially of a polyoxyethylene ether of lanolin alcohol condensed with 16 mols of ethylene oxide; and
Claim 8
Dependent Claim
16 words
The composition of claim 2, wherein said alkanolamide is a diethanolamide of coconut oil fatty acid.
Claim 9
Dependent Claim
20 words
a non-ionic surfactant consisting essentially of a polyoxyethylene ether of lanolin alcohol condensed with 16 mols of ethylene oxide, and
Claim 10
Dependent Claim
102 words
a diethanolamide of coconut oil fatty acid; said liquid fraction of lanolin being present in a concentration of from 1 to 3% by weight of the composition, said surfactant being present in a ratio of from about 1:1 to about 3:1 relative to the amount of said liquid fraction of lanolin, and said alkanolamide being present in a ratio of from about 1/2 :1 to about 7:1 relative to the amount of said liquid fraction of lanolin, whereby to effect complete solubilization of said liquid fraction of lanolin said composition being clear and transparent as initially produced and without requiring filtration thereof.
Claim 11
Dependent Claim
78 words
The composition of claim 3, wherein said liquid fraction of lanolin is present in a concentration of approximately 1 percent by weight, said non-ionic surfactant is present in a concentration of from approximately 2 to 3 percent by weight, and said alkanolamide is a diethanolamide of coconut oil fatty acid, present in a concentration of from approximately 0.5 to 3 percent by weight, the lower the concentration of said non-ionic surfactant the higher the concentration of said diethanolamide.
Claim 12
Dependent Claim
80 words
a higher fatty acid alkanolamide: said surfactant being present in a ratio of from about 1:1 to about 3:1 relative to the amount of said liquid fraction of lanolin, and said alkanolamide being present in a ratio of from about 1/2 :1 to about 7:1 relative to the amount of said liquid fraction of lanolin, whereby to effect synergistic solubilization of said liquid fraction of lanolin said composition being clear and transparent as initially produced and without requiring filtration thereof.
Claim 13
Dependent Claim
5 words
A composition consisting essentially of:
Claim 14
Dependent Claim
124 words
A liquid composition consisting essentially of: a. water b. a liquid fraction of lanolin, c. a non-ionic surfactant consisting essentially of a polyoxyethylene ether made by condensing lanolin alcohols with 16 mols of ethylene oxide; and d. a higher fatty acid alkanolamide; said surfactant and said alkanolamide each being present in ratios relative to the amount of said liquid fraction of lanolin to effect synergistic solubilization of said liquid fraction of lanolin, said ratio of said surfactant to said liquid fraction of lanolin being from about 1:1 to about 3:1, and said ratio of said alkanolamide to said liquid fraction of lanolin being from about 1/2 :1 to about 7:1 said composition being clear and transparent as initially produced and without requiring filtration thereof.
