Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 81 words
A thickening composition consisting essentially of from about 5 to about 90 weight % of xanthan gum, from about 5 to about 90 weight % of guar gum, and from about 5 to about 90 weight % of starch ether, the xanthan gum being unmodified by a polyvalent cation and being unmodified by heating in a dry state before blending with the guar gum, the composition exhibiting a synergistic increase in viscosity compared to the additive viscosities of the individual components.
Claim 2
Dependent Claim 81 words
A thickening composition consisting essentially of from about 5 to about 90 weight % of xanthan gum, from about 5 to about 90 weight % of guar gum, and from about 5 to about 90 weight % of starch ether, the xanthan gum being unmodified by a polyvalent cation and being unmodified by heating in a dry state before blending with the guar gum, the composition exhibiting a synergistic increase in viscosity compared to the additive viscosities of the individual components.
Claim 3
Dependent Claim 41 words
A composition according to claim 1 containing from about 20 to about 70 weight % of xanthan gum, from about 15 to about 45 weight % of guar gum, and from about 15 to about 55 weight % of starch ether.
Claim 4
Dependent Claim 38 words
A composition according to claim 2 containing from about 40 to about 60 weight % xanthan gum, from about 22.5 to about 25 weight % guar gum, and from about 17.5 to about 25 weight % starch ether.
Claim 5
Dependent Claim 41 words
A composition according to claim 2 containing from about 30 to about 60 weight % of xanthan gum, from about 20 to about 35 weight % of guar gum, and from about 20 to about 35 weight % of starch ether.
Claim 6
Dependent Claim 41 words
A composition according to claim 2 containing from about 20 to about 40 weight % of xanthan gum, from about 25 to about 45 weight % of guar gum, and from about 35 to about 55 weight % of starch ether.
Claim 7
Dependent Claim 41 words
A composition according to claim 2 containing from about 50 to about 70 weight % of xanthan gum, from about 15 to about 25 weight % of guar gum, and from about 15 to about 25 weight % of starch ether.
Claim 8
Dependent Claim 25 words
A composition according to claim 2 containing about 50 weight xanthan gum, about 25 weight % guar gum, and about 25 weight % starch ether.
Claim 9
Dependent Claim 26 words
A composition according to claim 2 containing about 40 weight % xanthan gum, about 30 weight % guar gum and about 30 weight % starch ether.
Claim 10
Dependent Claim 26 words
A composition according to claim 2 contaiing about 50 weight % xanthan gum, about 22.5 weight % guar gum, and about 22.5 weight % starch ether.
